Eva has 36 different combinations of camping gear to choose from.
What are combinations?Combinations are arrangements of a given set of objects, without regard to their order. Combinations are used in mathematics to describe the possible arrangements of a given set of objects.
In this case, there are 3 sleeping bags, 2 pillows, and 6 tents. In order to determine the total number of combinations, Eva would need to multiply 3x2x6 which equals 36.
If she decides to pick a sleeping bag first, then she can pick any of the 3 available sleeping bags. She would then need to pick one of the 2 pillows and one of the 6 tents. If the order in which she selects her gear does not matter, then she can use the same method to determine the number of combinations available.

What is combination?Combination involves selecting items from a set of items without regard to the order in which they are selected. It is typically expressed using the notation C(n,r) which stands for the number of combinations of n items taken r at a time, where n is the total number of items and r is the number of items taken at a time.
This is an example of a combination problem, as Eva is looking to select a set of items from multiple categories, rather than a permutation problem, which would be selecting a set of items where the order matters.
In this case,
n= 6 (the number of tents)+ 3 (the number of sleeping bags)+ 2 (the number of pillows)= 11.
We want to choose 1 of each item, so r is 3.
Plugging 11 and 3 into the formula, we get
11C3 = 11! / (3! * 8!)
= 11 * 10 * 9 / (3 * 2 * 1)
= 11 * 5

7,600 dollars is placed in a savings account with an annual interest rate of 6%. If no money is added or removed from the account, which equation represents how much will be in the account after 7 years?
Answers:
M=7,600(1+0.06)(1+0.06)
M=7,600(1-0.06)^7
M=7,600(1+0.06)^7
M=7,600(0.06)^7
Step-by-step explanation:
The equation that represents how much will be in the account after 7 years is:
M = 7,600(1+0.06)^7
Here's the explanation:
The formula for calculating the future value (M) of a present value (P) invested at an annual interest rate (r) for a certain number of years (t) is M = P(1+r)^t.
In this case, the present value (P) is 7,600 dollars, the annual interest rate (r) is 6% or 0.06, and the number of years (t) is 7.
Substituting these values into the formula, we get M = 7,600(1+0.06)^7. This represents how much will be in the account after 7 years if no money is added or removed from the account.
You spin the spinner twice the numbers are 5,4,6. What is the probability of landing on a number greater than 4 and then landing on a number less than 6
Answer:
Step-by-step explanation:
The probability of landing on a number greater than 4 on the first spin is 2/3, because 2 out of the 3 numbers (5, 4, 6) are greater than 4.
If the first spin lands on a number greater than 4, then there are two numbers left (4 and 5) for the second spin. The probability of landing on a number less than 6 on the second spin is 2/2 or simply 1, because both 4 and 5 are less than 6.
Therefore, the probability of landing on a number greater than 4 on the first spin and a number less than 6 on the second spin is:
(2/3) x (1) = 2/3 or approximately 0.67.

two similar sized potatoes start at 20 degrees celsius. one potato is placed in the oven at 200 degrees celsius. after ten minutes the baked potato is 37 degrees celsius. according to newton's equation, how long will it take for the potato to reach 90 degrees celsius to the nearest tenth of a minute?
The potato will take approximately 3.1 minutes to reach a temperature of 90 degrees Celsius to the nearest tenth of a minute.
What is the Newton's equation?According to Newton's equation, we need to find time taken for the potato to reach 90 degrees Celsius to the nearest tenth of a minute.
Newton's law of cooling equation is used.
Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature.
The law of cooling is given as
[tex]T(t) = T_m + (T_0 - T_m)e^{-kt}[/tex]
whereT(t) is the temperature of the object at time t.
[tex]T_0[/tex] is the temperature of the object initially.
[tex]T_m[/tex] is the temperature of the medium in which the object is kept.
k is a positive constant.
The formula is used to solve for the time it will take the baked potato to reach 90 degrees Celsius.
This is given as:
[tex]T(t) = T_m + (T_0 - T_m)e^{-kt}[/tex]
[tex]90 = 20 + (37 - 20)e^{-kt}[/tex]
Let's start by solving for k.
[tex]37 = 20 + (37 - 20)e^{-k(10)}[/tex]
[tex]17 = 17e^{-10k}[/tex]
[tex]ln(1) = -10k[/tex]
[tex]k = 0[/tex]
Substituting k = 0 in the equation,
we have
[tex]90 = 20 + (37 - 20)e^{0(t)}[/tex]
[tex]\frac{70}{17} = e^{(0(t))}[/tex]
Taking the natural log of both sides,
[tex]ln\frac{70}{17} = lne^{0(t)}[/tex]
[tex]t= 3.0748 minutes[/tex]
Therefore, it will take approximately 3.1 minutes for the potato to reach 90 degrees Celsius to the nearest tenth of a minute.

Sandesh sold 15kgs of apples for 2100rs and gained 12%. At what price per kg should he sell to gain 20% ?
As per the given percentage, Sandesh should aim to sell his apples at 250rs per kg in order to gain 20% profit.
Let C be the cost of the 15kgs of apples. Sandesh gained 12%, so his profit is 0.12C. We know that Sandesh sold the apples for 2100rs, so we can write an equation:
C + 0.12C = 2100
Simplifying this equation gives:
1.12C = 2100
Dividing both sides by 1.12 gives:
C = 1875
So Sandesh's cost for 15kgs of apples was 1875rs.
Now, we need to find the selling price per kg of apples that Sandesh should aim for in order to gain 20% profit. Let P be the selling price per kg of apples.
Since Sandesh wants to gain 20% profit, his selling price per kg of apples needs to be his cost plus 20% of his cost, or 1.2 times his cost.
So we can write another equation:
1.2C = 15P
Substituting the value of C we found earlier, we get:
1.2(1875) = 15P
Simplifying gives:
P = 250

Hunter is playing a video game on his tablet. The screen on the tablet is 8 inches long and 6 inches tall. The monster he is fighting on-screen is 5 inches tall. If Hunter connects his tablet to a 40-inch TV screen with the same 4:3 aspect ratio, how tall will the monster be?
The height of the monster on the 40-inch TV screen will be 8 inches, which is larger than its height on Hunter's tablet.
First, we need to find out the scale of the monster on Hunter's tablet, which can be calculated as follows
Screen aspect ratio = 8/6 = 4/3
Height of monster on tablet = 5 inches
Width of monster on tablet = (4/3) x 5 = 6.67 inches (because the aspect ratio is 4:3, the width of the monster is 4/3 times its height)
Next, we need to find out the height of the monster on the 40-inch TV screen, which has the same 4:3 aspect ratio as the tablet screen. We can do this by using a proportion
Tablet screen height, Tablet screen width = TV screen height : TV screen width
Substituting the values we know, we get,
6 inches : 8 inches = TV screen height : 10.67 inches (because 40 inches is 4/3 times the width of the TV screen)
Solving for TV screen height, we get,
TV screen height = (6/8) x 10.67 = 8 inches

Solve the following system of equations algebraically:x+y=7, x+2y=11
Answer:
(3, 4)
Step-by-step explanation:
Pre-SolvingWe are given the following system of equations:
x + y = 7
x + 2y = 11
We want to solve to find the values of x and y.
SolvingThere are three ways to solve a system of equations: substitution, graphing, and elimination.
Any one of these methods will work, however let's do elimination for this.
To eliminate, we can add or subtract the equations together to clear the variables.
It is helpful to rewrite this system as:
x + 2y = 11
x + y = 7
We can subtract x + y = 7 from x+2y=11:
x + 2y = 11
-(x+y = 7)
This is equivalent to:
x + 2y = 11
-x - y = - 7
_________
0 + y = 4
So, y = 4
Now, we need to find x.
We can plug in 4 for y in either x + y = 7 or x + 2y = 11.
Taking x + y =7 for instance:
x + 4 = 7
Subtract 4 from both sides.
x = 3
So, x = 3 and y =4
As a point, this is (3, 4).
The length in inches of each side of a square is given by the expression x + 2. the area of the square can be represented by (x + 2)2−16=0 when the area is 16 square inches. what is the value of x?
The value of x is 2 inches, which represents the length of each side of the square.
We can start by setting up the equation using the given expression for the side length and the given area:
(x + 2)² - 16 = 0
Expanding the left side and simplifying, we get:
x² + 4x = 0
Factoring out x, we get:
x(x + 4) = 0
So, either x = 0 or x = -4. However, since x represents a length, it must be positive. Therefore, the only solution is:
x = 0 + 2 = 2
So the value of x is 2 inches.

What is an equation for the quadratic function represented by the table shown?
(0,-1),(2,3),(4,-1),(6,-13)
The equation of the quadratic function represented by the given table is y = -x² + 4x - 7.
What is a quadratic function?A quadratic function is a function of the form:\sf(x) = ax^2 + bx + c\swhere a, b, and c are constants and x is the parameter. The graph of a quadratic function is a parabola, which is an Inverted curve. Whether the parabola opens up (if a > 0) or down (if a 0) depends on the sign of the coefficient a.
The width of the parabola is also determined by the coefficient a. The parabola is narrow if |a| is greater than 1. (i.e. it has a small width relative to its height). The parabola is wide if |a| is greater than 1.
The standard form of the quadratic equation is given as:
y = ax² + bx + c
Substitute the value of x and y from the table:
3 = a(2)² + b(2) + c
4a + 2b + c = 3........(1)
For point (4, -1):
-1 = a(4)² + b(4) + c
16a + 4b + c = -1..........(2)
For (6, -13):
-13 = a(6)² + b(6) + c
36a + 6b + c = -13..........(3)
From 1 we have:
c = 3 - 4a - 2b
Substitute the value of c in equation 2 and 3:
16a + 4b + 3 - 4a - 2b = - 1
12a + 2b = - 4........(4)
36a + 6b + 3 - 4a - 2b = -13
32a + 4b = -16.......(5)
Multiply equation 4 with 2 and subtract with equation 5:
32a + 4b = -16
-(24a + 4b = - 8)
a = -1
Substitute the value of a in equation 5:
32(-1) + 4b = -16
-32 + 4b = -16
b = 4
Substitute the value of a and b in equation 1:
16a + 4b + c = -1
16(-1) + 4(4) + c = -1
-16 + 8 + c = -1
-8 + c = -1
c = 7
Using the algebraic techniques we have:
a = -1
b = 4

Line A has a y-intercept of 3 and is perpendicular to the line given by
y = 5x + 2.
What is the equation of line A?
Give your answer in the form y = mx + c, where m and c are integers or
fractions in their simplest forms.
Answer:
Step-by-step explanation:
The given line is y = 5x + 2. We know that any line perpendicular to this line will have a slope that is negative reciprocal of 5. The negative reciprocal of 5 is -1/5.
Line A is perpendicular to y = 5x + 2, so it has a slope of -1/5. We also know that the y-intercept of line A is 3. Therefore, the equation of line A can be written as:
y = (-1/5)x + 3
or in the form y = mx + c, where m = -1/5 and c = 3.
Given that m∠A=(16x)°, m∠C=(8x+20)°, and m∠D=128°, what is m∠B
The value of m∠B is 212 - 24x.
How did we get the value?The totality of the angles in a quadrilateral is always amount to 360°. This is a primary property of all quadrilaterals, irrespective of their shape or size.
As a result, irrespective of the shape say if you are dealing with a square, rectangle, parallelogram, trapezoid, or any other type of quadrilateral, the totality of the angles will always be sum to 360°.
To determine the value of m∠B, one can employ the notion that the sum of the angles in a quadrilateral is 360°.
Thus,
m∠A + m∠B + m∠C + m∠D = 360
Substituting the given values, we get:
(16x)° + m∠B + (8x+20)° + 128° = 360
Simplifying and solving for m∠B, we get:
m∠B = 360 - (16x)° - (8x+20)° - 128°
m∠B = 212 - 24x
Therefore, the value of m∠B is 212 - 24x.

What is triangle?A triangle is a closed two-dimensional geometric figure with three straight sides and three angles. It is one of the basic shapes in geometry and can be classified based on the length of its sides and the measures of its angles. The sum of the interior angles of a triangle is always 180 degrees, and the length of each side is less than the sum of the lengths of the other two sides. Triangles have many properties and are used in various mathematical and real-world applications, including trigonometry, geometry, and engineering.
Here,
Since all the angles are equal, we can set up the following proportion:
LO/NO = 7/2
Multiplying both sides by NO, we get:
LO = (7/2)NO
We can also use the fact that the angles are equal to set up an equation involving m:
m + (1/2)LO + (1/2)NO = 180
Substituting LO = (7/2)NO, we get:
m + (7/4)NO = 180
Now we can substitute the given values for LO and NO:
m + (7/4)(14) = 180
m + 49 = 180
m = 131
Therefore, the answer is: m = 131, LO = 49, NO = 14

The probability that exactly 3 homes will be sold tomorrow is A) 0.1809.
To solve this problem, we can use the Poisson distribution formula, which is:
P(x; μ) = (e^-μ) (μ^x) / x!
where P(x; μ) is the probability of x events happening in a given time period, μ is the mean number of events in that time period, e is the mathematical constant approximately equal to 2.71828, and x! is the factorial of x.
In this case, we want to find the probability of exactly 3 homes being sold tomorrow, given that the average number of homes sold is 2 per day. So, we plug in μ = 2 and x = 3 into the formula:
P(3; 2) = (e^-2) (2^3) / 3! = 0.1809
Therefore, the probability that exactly 3 homes will be sold tomorrow is 0.1809 or approximately 18.09%. This means that out of every 100 days, we can expect that around 18 of those days will have exactly 3 homes sold by Acme Realty Company.

The measure of angle c is (4x-24. 6) and measure of angle d is (x+11. 3). If the angles are supplementary, find the value of x and measure of angle d
The measurement of of angle c is (4x-24. 6) and measure of angle d is (x+11. 3). If the angles are supplementary, the value of x is 38.66.
The measure of angle c is (4x-24. 6)
The measure of angle d is (x+11. 3)
If both angles are supplementary angles then,
angle c + angle d = 180
(4x-24. 6) + (x+11. 3) = 180
5x - 13.3 = 180
5x = 180 + 13.3
5x = 193.3
x = 193.3/5
x = 38.66
So, the value of x is 38.66
What distinguishes complimentary from supplementary angles?
Two angles are said to be supplementary angles because they combine to generate a linear angle when their sum is 180 degrees. When two angles add up to 90 degrees, however, they are said to be complimentary angles and together they make a right angle.
