A toy maker needs to make $17,235 per month to meet his cost. Each toy sells for $45. How many toys does he need to sell in order to break even
Answer:
Step-by-step explanation:
i assume the figure he needs to "make" is the turnover and not the marginal profit - no indication of the cost of the toys he sells is given so it is impossible to work out the marginal profit of the each toy sold. (Though how the toymaker worked out the turnover required without knowing the cost of the toy is beyond me - though that didn't stop British Leyland pricing their best selling Mini in the 1970s.)
In this case divide the income required by the price of each toy, but as the income must be at least the required amount, any fractional part of a toy must be rounded *UP* to the next whole number.
17,235 ÷ 45 = 383 (so no rounding is needed).
He needs to sell 383 toys (made at zero marginal cost).
n+d=21
0.05n + 0.10d= 1.70
Answer:
To solve the system of equations:
n + d = 21 ---(1)
0.05n + 0.10d = 1.70 ---(2)
We can use the substitution method by solving for one variable in terms of the other from equation (1) and substituting it into equation (2).
Solving equation (1) for n:
n = 21 - d
Substituting this expression for n into equation (2):
0.05(21 - d) + 0.10d = 1.70
Distributing the 0.05:
1.05 - 0.05d + 0.10d = 1.70
Combining like terms:
0.05d = 0.65
Dividing both sides by 0.05:
d = 13
Substituting this value of d into equation (1):
n + 13 = 21
Solving for n:
n = 8
Therefore, the solution to the system of equations is n = 8 and d = 13.
Sugar Shack gourmet candy shop’s signature candy mixture contains sour drops, chocolate chews, and tangy twists in the ratio 2:3:4, respectively. How many more pounds of tangy twists than sour drops are in a 45-pound batch of this signature candy mixture?
Since Sour Drops, Chocolate Chews and Tangy Twists are in the ratio 2:3:4, respectively, it follows that Sour Drops account for 2/9 and Tangy Twists account for 4/9 of the candy mixture. So, Sour Drops make up (2/9)(45) = 2 × 5 = 10 pounds, while Tangy Twists make up (4/9)(45) = 4 × 5 = 20 pounds of the 45-pound candy mixture. Therefore, there are 20 – 10 = 10 pounds more Tangy Twists than Sour Drops. Alternatively, the given ratio means that Tangy Twists account for 4/9 – 2/9 = 2/9 more of the candy mixture than Sour Drops do. So, in a 45-pound batch of the candy mixture, there would be (2/9)(45) = 2 × 5 = 10 pounds more Tangy Twists than Sour Drops.
Nyelle purchases some Sour Drops, Chocolate Chews and Tangy Twists to combine into her personal batch of the Sugar Shack’s signature candy mixture using the same proportions as the previous problem. If the prices per pound for the candies are $6.00 for Sour Drops, $3.50 for Chocolate Chews and $4.25 for Tangy Twists, what is the total cost (not including tax) to purchase the exact amounts of all three candies required to make 4.5 pounds of this signature candy mixture?
Again, since Sour Drops, Chocolate Chews and Tangy Twists are in the ratio 2:3:4, respectively, it follows that Sour Drops, Chocolate Chews and Tangy Twists account for 2/9, 3/9 = 1/3 and 4/9 of the candy mixture, respectively. So, to make 4.5 pounds of this candy mixture, Nyelle needs (2/9)(4.5) = 2 × 0.5 = 1 pound of Sour Drops, (1/3)(4.5) = 1.5 pounds of Chocolate Chews and (4/9)(4.5) = 4 × 0.5 = 2 pounds of Tangy Twists. At the given prices per pound, we calculate Nyelle’s total cost to be 1(6.00) + 1.5(3.50) + 2(4.25) = 6 + 5.25 + 8.50 = $19.75.
Rae purchases 4.5 pounds of the signature candy mixture when it goes on sale at the Sugar Shack for $4.00 per pound. What is the absolute difference between Nyelle’s and Rae’s total costs (not including tax) to get 4.5 pounds of the signature candy mixture?
At a sale price of $4.00 per pound, 4.5 pounds of the candy mixture would cost Rae 4.5(4.00) = $18.00. From the previous problem, we know that Nyelle’s total cost was $19.75. Therefore, the absolute difference between Nyelle’s and Rae’s total costs is 19.75 – 18.00 = $1.75.

a committee of 7 members is to be chosen from 6 artists, 4 singers and 5 writers. in how many ways can this be done if in the committee there must be at least one member from each group and at least 3 artists ?
There are 1124 ways to choose a committee of 7 members with at least one member from each group and at least 3 artists.
Here, we have to solve this problem, we can use the concept of combinations, which involves counting the ways to choose a specific number of items from a larger set without regard to the order of selection.
Given the conditions that at least one member must be chosen from each group (artists, singers, writers) and there must be at least 3 artists, we can break down the problem into cases.
Case 1: Choosing 1 artist, 1 singer, and 5 members from the remaining groups (writers).
Case 2: Choosing 2 artists, 1 singer, and 4 members from the remaining groups (writers).
Case 3: Choosing 3 artists, 1 singer, and 3 members from the remaining groups (writers).
For each case, we will calculate the number of ways to choose members and then sum up the results from all three cases to get the total number of ways.
Let's calculate the number of ways for each case:
Case 1:
Number of ways to choose 1 artist: 6C1 (6 ways)
Number of ways to choose 1 singer: 4C1 (4 ways)
Number of ways to choose 5 writers: 5C5 (1 way)
Total ways for case 1: 6C1 * 4C1 * 5C5 = 6 * 4 * 1 = 24
Case 2:
Number of ways to choose 2 artists: 6C2 (15 ways)
Number of ways to choose 1 singer: 4C1 (4 ways)
Number of ways to choose 4 writers: 5C4 (5 ways)
Total ways for case 2: 6C2 * 4C1 * 5C4 = 15 * 4 * 5 = 300
Case 3:
Number of ways to choose 3 artists: 6C3 (20 ways)
Number of ways to choose 1 singer: 4C1 (4 ways)
Number of ways to choose 3 writers: 5C3 (10 ways)
Total ways for case 3: 6C3 * 4C1 * 5C3 = 20 * 4 * 10 = 800
Now, add up the total ways from all three cases:
Total ways = 24 + 300 + 800 = 1124
So, there are 1124 ways to choose a committee of 7 members with at least one member from each group and at least 3 artists.

An Ixl question from sixth grade IXL:FF.15 Rectangles: relationship between perimeter and area
The dimensions of the gray rectangle are approximately 61.9 km by 218.1 km.
What is perimeter of a rectangle?The distance around a rectangle's outside edge is known as its perimeter. It is computed by summing the measurements of the rectangle's four sides. The perimeter P of a rectangle with sides of length l and width w is given by:
P = 2l + 2w.
By understanding that a rectangle contains two pairs of equal sides (length and breadth), and that the distance around the rectangle is equal to the total of these four sides, one may deduce this formula.
Let us suppose the dimensions of the gray triangle as x and y.
The perimeter of rectangle is given as:
P = 2(1 + b)
For the blue triangle we have:
P = 2(72 + 68)
For the gray triangle we have;
P = 2(x + y)
Equating the two since they are equal we have:
2(72 + 68) = 2(x + y)
280 = x + y
We also know the area of the gray triangle thus:
xy = 3876
Substituting y = 280 - x into the second equation, we get:
x(280 - x) = 3876
x² - 280x + 3876 = 0
x = (280 ± √(280² - 4(1)(3876))) / 2
x ≈ 62.7 or x ≈ 61.9
We may discard the negative answer since a rectangle's dimensions cannot be negative.
Substituting the value of x we have:
y = 280 - 61.9 = 218.1 km.
Hence, the dimensions of the gray rectangle are approximately 61.9 km by 218.1 km.

a different pattern is made using 20 straight lines and 14 arcs
The total cost of metal in the pattern would be £24.6.
What is the total cost of the pattern?
Let's assume that the cost of one arc is 3x, then the cost of one straight line would be 2x.
The total number of lines and arcs is given as 20 + 14 = 34.
Since 20 straight lines cost £12, the cost of one straight line is £12/20 = £0.6.
Therefore, the cost of one arc is (3/2) * £0.6 = £0.9.
The total cost of the 20 straight lines would be 20 x £0.6 = £12.
The total cost of the 14 arcs would be 14 x £0.9 = £12.6.

where v is measured in meters per second and t is the time in seconds. Find the velocity and acceleration of the object when t = 3. What can be said about the speed of the object when the velocity and acceleration have opposite signs?
In calculus, the derivative is a fundamental concept that measures how a function changes with respect to its input variable. It is a mathematical tool used to study the behavior of functions and is used in many areas of mathematics, physics, engineering, and economics.
When t = 3, the velocity of the object is 27 meters per second, and its acceleration is -2 meters per second squared.
When the velocity and acceleration have opposite signs, the speed of the object is decreasing. The acceleration of an object can be calculated using the derivative of the velocity of the object with respect to time.
v(t) = 36 - t², 0 ≤ t ≤ 6
Let us take the derivative of the velocity, v(t), to obtain acceleration, a(t) = v'(t) = -2t.When t = 3, v(3) = 36 - 3² = 27 meters per second.Therefore, when t = 3, the velocity of the object is 27 meters per second. When t = 3, a(3) = -2(3) = -6 meters per second squared. The object's acceleration is -6 meters per second squared.

please help!!!
The probability that a person treated for an energy drink-related emergency was under 40 given that the person was at least 18 years old is approximately 0.550 or 55.0%.
What is the formula for probability?In general, probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in a sample space. Event probability P(E) = (number of favourable outcomes) (Sample space).
We must use conditional probability to determine the likelihood that a person treated for an energy drink-related emergency was under 40, given that the person was at least 18 years old.
We can use the following formula:
P(A | B) = P(A and B) / P(A and B) (B)
where A is the event "the person is under 40" and B is the event "the person is over 18".
According to the table, 11,146 people under the age of 40 and over the age of 18 were treated for energy drink-related emergencies. The total number of people over the age of 18 who have been treated for energy drink-related emergencies is 20,244.
So,
P(A, B) = 11,146
P(B) = 20,244
Therefore,
P(A and B) / P(B) = 11,146 / 20,244 0.550
So the probability that a person treated for an energy drink-related emergency was under 40 is approximately 0.550 or 55.0% if the person was at least 18 years old.

What is simple interest?Simple interest is a type of interest that is calculated on the original principal amount of a loan or investment. It is a fixed percentage of the principal amount that is paid by the borrower or earned by the lender over a specific period of time.
According to question:To compare the two options, we need to calculate the total cost of each option and compare them.
Option 1: 10% discount and pay off with 4% simple interest
The discount reduces the price of the television to $1000 x 0.9 = $900. If the customer chooses to pay it off at 4% simple interest, the total cost would be:
Total cost = $900 + ($900 x 0.04 x 3) = $972
Option 2: Full price and pay off in 3 years with no interest
The total cost of this option would be simply the full price of $1000 paid over 3 years, so:
Total cost = $1000 / 3 = $333.33 per year x 3 years = $1000
Comparing the two options, we see that Option 1 with the discount and 4% simple interest has a total cost of $972, while Option 2 with no discount and no interest has a total cost of $1000. Therefore, Option 1 is the better choice as it has a lower total cost.

Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse.
To construct the graph of the hyperbola, the procedure is as follows:
Marty first identifies the center of the hyperbola as (-5,2), and that the hyperbola opens up and down. Since a = 6, the coordinates of the vertices are (-5, -4) and (-5, 8).The slopes of the asymptotes of this parabola are a = ± 3/4, and the asymptotes pass through the center of the hyperbola. The equations of the asymptotes are y - 2 = ± 3/4(x + 5).Equation of an hyperbolaThe equation of a vertical hyperbola with center (x*, y*) is given according to the following equation:
(y - y*)²/a² - (x - x*)²/b² = 1.
A vertical hyperbola opens up and down.
In this problem, the equation is:
(y + 2)²/36 - (x + 5)²/64 = 1.
Hence the center is:
(-5, 2).
The value of coefficient a is:
a² = 36 -> a = 6.
Then the vertices of the hyperbola are:
(-5, 2 - 6) = (-5,-4).(-5, 2 + 6) = (-5,8).The slopes of the asymptotes of the parabola are given as follows:
±a/b.
Hence:
a/b = 6/8 = 3/4.-a/b = -6/8 = -3/4.Since the asymptotes pass through the center, the equation is:
y - 2 = ± 3/4(x + 5).

Two angles of an irregular polygon are 100⁰
each and each of the remaining angles is 1300.
Find the number of sides of the polygon.
there is no polygon that satisfies the given conditions.
Why it is and what is a Polygon?
Let the number of sides of the polygon be n.
We know that the sum of angles of an n-sided polygon is (n-2) × 180 degrees.
In this polygon, two angles are 100 degrees each, and the remaining (n-2) angles are 130 degrees each.
So, we can set up an equation:
2 × 100 + (n-2) × 130 = (n-2) × 180
Simplifying this equation, we get:
200 + 130n - 260 = 180n - 360
Solving for n, we get:
50n = 100
n = 2
However, a polygon with only 2 sides is not possible.
Therefore, there is no polygon that satisfies the given conditions.
A polygon is a 2-dimensional geometric figure that is formed by connecting a finite number of line segments to create a closed shape. These line segments are called sides of the polygon. The sides of a polygon only intersect at their endpoints, and the endpoints of each side are called vertices. A polygon with three sides is called a triangle, a polygon with four sides is called a quadrilateral, and a polygon with more than four sides is generally referred to by its number of sides (e.g. a pentagon has five sides, a hexagon has six sides, etc.).

Answer:
x = 9/10.
Step-by-step explanation:
0.5(4x + 9) = 3x * 7/3
2x + 9/2 = 3x * 7/3
2x + 9/2 = 7x
5x = 9/2
x = 9/10.
there are 20 rows of seats on a concert hall: 25 seats are in the 1st row, 27 seats on the 2nd row, 29 seats on the 3 rd row, and so on. if the price per ticket is $32, how much will be the total sales for a one-night concert if all seats are taken?
Answer:
Step-by-step explanation:
To solve this problem, we need to find out how many seats there are in total, and then multiply that by the price per ticket.
To find the total number of seats, we need to add up the number of seats in each row. We can use the formula for an arithmetic sequence to do this:
S = n/2 * (a + l)
where S is the sum of the sequence, n is the number of terms, a is the first term, and l is the last term.
In this case, we have:
n = 20 (since there are 20 rows)
a = 25 (since there are 25 seats in the first row)
d = 2 (since the difference between each row is 2 seats, the common difference is 2)
We can use d to find the last term as well:
l = a + (n-1)*d
l = 25 + (20-1)*2
l = 25 + 38
l = 63
Now we can plug these values into the formula:
S = 20/2 * (25 + 63)
S = 10 * 88
S = 880
So there are 880 seats in total.
To find the total sales, we just need to multiply by the price per ticket:
total sales = 880 * $32
total sales = $28,160
Therefore, the total sales for a one-night concert with all seats taken would be $28,160.
