solve a package of 17 sliced apples $2.21.How much would a package with 25 sliced apples cost at the same price per slice?????solve pleaseee middle school
Answer:
$3.25
Step-by-step explanation:
So,
If a package of 17 sliced apples is $2.21, lets find out the price per apple.
2.21 / 17 = 0.13
so, the price per apple is $0.13
Now, we find the price of a package with 25 sliced apples.
0.13 x 25 = 3.25
So, the price of a package with 25 sliced apples is $3.25
Hope this helps!
The midpoint of AB is M(-4,2). If the coordinates of A are (-6,5), what are the
coordinates of B?
Answer:
(-2,-1)
Step-by-step explanation:
Midpoints are found when you do ([x(subscript A) + x(subscript B)]/2, [y(subscript A) + y(subscript B)]. Therefore your equation (for x of B) should look like this:
-4 = ([-6+x]/2)
After you solve for x, you should have gotten -2 for x.
Then you do the same for y:
2 = ([5+y]/2)
You should get -1. Your final answer should be (-2, -1)

A couple is starting a family and decides to have four children. Assume that the probability of having a boy or have a girl are equal. a) Find a probability model for the number of girls the couple has. b) Find the probability that the couple has at least one girl. c) What is the probability that the couple has exactly one boy or exactly one girl
Answer:
0.9375 ; 0.5
Step-by-step explanation:
Given that :
p = 0.5
Probability model for the Number of girls the couple has :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 0) = 4C0 * 0.5^0 * 0.5^4 = 0.0625
P(x = 1) = 4C1 * 0.5^1 * 0.5^3 = 0.25
P(x = 2) = 4C2 * 0.5^2 * 0.5^2 = 0.375
P(x = 3) = 4C3 * 0.5^3 * 0.5^1 = 0.25
P(x = 4) = 4C4 * 0.5^4 * 0.5^0 = 0.0625
Probability of having atleast one girl
Number of trials, n = 4
P(x ≥ 1) = p(x = 1) + p(x = 2) + p(x = 3) + p(x = 4)
Using the relation :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Using calculator ;
P(x ≥ 1) = 0.9375
Probability of having exactly one boy or exactly one girl
1 boy 3 girls OR 1 girl 3 boys
P(x = 1)
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 1) = 4C1 * 0.5^1 * 0.5^3
P(x = 1) = 4 * 0.5 * 0.125
P(x = 1) = 0.25
The probability of having one girl, 3 boys and vice versa is 0. 25
Hence, Probability of having exactly one boy or exactly one girl
0.25 + 0.25 = 0.5

Nancy is trying to decide which cell phone plan would be the right one for her. She has
narrowed her choices down to two, Spirit and Horizon. Spirit (s) has a fixed fee of $20 and an
additional charge of 5 cents per minute. Horizon (h) has no fee and charges 15 cents per minute.
Write two equations that could be used to determine the total cost for each plan for 300 minutes?
A. s = 5x + 20
h=15x
B. s = 0.05x + 20
h = 0.15x
C. s = 15x
h = 5x + 20
D. s = 0.15x
h = 0.05x + 20
Find the perimeter of this semi-circle with diameter,
d
= 37cm.
Give your answer rounded to 1 DP.
Answer:
58.1cm
Step-by-step explanation:
perimeter of a semi-circle = πd/2
d is the diameter
Given
diameter = 37cm
Perimeter of the semi circle = π(37)/2
Perimeter of the semi circle = 18.5(3.14)
Perimeter of the semi circle = 58.09 cm
Hence the perimeter of the semi-circle is 58.1cm
What is the equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line represented by y=34x−8?
Answer:
The equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line is:
[tex]y=-\frac{1}{34}x+\frac{91}{17}[/tex]Step-by-step explanation:
We know the slope-intercept form of the line equation
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
Given the line
[tex]y=34x-8[/tex]
comparing with the slope-intercept form of the line equation
The slope m = 34
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 34
Thus, the slope of the the new perpendicular line = – 1/m = -1/34 = -1/34
Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values of slope = -1/35 and the point (12, 5)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-5=-\frac{1}{34}\left(x-12\right)[/tex]
Add 5 to both sides
[tex]y-5+5=-\frac{1}{34}\left(x-12\right)+5[/tex]
[tex]y=-\frac{1}{34}x+\frac{91}{17}[/tex]
Therefore, the equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line is:
[tex]y=-\frac{1}{34}x+\frac{91}{17}[/tex][tex]cot(x)=\sqrt{3}[/tex]

10/15=z/6
z/10=15/6
10/15=6/z
What is the answer to the proportion you set up in the last problem? Type ONLY the number in the box.
Answer:
10/Z=6/15
Step-by-step explanation:
To find the missing measurement we need to use similarity ratio
10/Z=6/15 cross multiply expressions
15z = 60 divide both sides by 15
z = 4
Find the value of x in the triangle shown below

490 divided by 7 and i need to know the answer for that please
The result of 490 divided by 7 is 70.
To calculate 490 divided by 7, we can perform long division as follows:
70
__________
7 | 490
- 49 (7 times 7)
_______
0 (no remainder)
In the first step, we divide 7 into the first digit of 490, which is 4. The quotient is 0, and we bring down the next digit, which is 9.
Next, we divide 7 into 49. The quotient is 7, and there is no remainder.
Therefore, the answer to 490 divided by 7 is 70.

Item 4 A movie theater sells 70 regular tickets and 40 matinee tickets in one day. Each regular ticket costs $15 and each matinee ticket costs $12. What is the total amount of ticket sales on this day?
Answer:
The total amount of ticket sales on this day is $1530.
Step-by-step explanation:
From the information given, the total amount of ticket sales would be equal to the result of multiplying the number of regular tickets sold for its price plus the number of matinee tickets sold for its price, which would be:
Ticket sales=15R+12M, where
R= number of regular tickets sold= 70
M= number of matinee tickets sold= 40
Now, you can replace these values on the formula to find the total amount of ticket sales on this day:
Ticket sales=15(70)+12(40)
Ticket sales=1050+480
Ticket sales=1530
According to this, the answer is that the total amount of ticket sales on this day is $1530.

Vertical Shift of Functions
Given a linear function
y = mx + b
The value of b is called the y-intercept or the y-coordinate where the line crosses the y-axis. If the function is shifted up by a value of k, then the new function is:
y' = mx + b + k
Similarily to shift the function down, the value of k is subtracted:
y''= mx + b - k
We are given the function:
[tex]\displaystyle y=\frac{2}{3}x+2[/tex]
1) To shift up the line, we select a value of k=10. The new shifted-up function is:
[tex]\displaystyle y=\frac{2}{3}x+2+10[/tex]
[tex]\displaystyle y=\frac{2}{3}x+12[/tex]
2) To shift down the line, we select a value of k=5. The new shifted-down function is:
[tex]\displaystyle y=\frac{2}{3}x+2-5[/tex]
[tex]\displaystyle y=\frac{2}{3}x-3[/tex]
3) To shift to the origin, we must select a specific value of k that cancels the y-intercept. We must shift down by k=2:
[tex]\displaystyle y=\frac{2}{3}x+2-2[/tex]
[tex]\displaystyle y=\frac{2}{3}x[/tex]
This new function has the y-intercept equal to 0

Find the Area. Simplify your answer.
Answer:
Area = [tex]9x^2[/tex] square units
Step-by-step explanation:
Key skills needed: Area of a parallelogram
1) This shape is a parallelogram, and the way to find the area of a parallelogram is:
[tex]A = bh[/tex]
A = area
b = base (the side at the bottom
h = the height ( the length that runs from one side to another and makes a right angle)
2) The base (b) would be 3x. The height (h) would also be 3x
3) This means A = [tex]3x(3x)[/tex]
3 times 3 is 9 --> and x times x is [tex]x^2[/tex]
