Step-by-step explanation:the ratio is 4 boots for every 5 athletic shoe so you divide 40 by 5 and get 8 so you have to multiply 8 by 4 which 32 so when they stock 40 pair of athletic shoes they will also stock 32 pairs of boots
No receives a $5 discount each month on his cell phone bill because he signed up for autoplay from his bank account over the last eight months nor has pay a total of $284 for his cell phone bill what would Noah be charged for his cell phone bill each month if he stopped using autoplay?
Answer:
$36Step-by-step explanation:
Normally Noah is expected to pay an amount without a discount.
let this amount be x
so the amount paid monthly after the discount is removed is (x-5)
Noah paid this amount for 8 months
(x-5)*8=248
solving for x we will get the amount that Noah is expected to be charged when he stopped using the autoplay
(x-5)*8=248
8x-40=248
8x=248+40
8x=288
divide both sides by 8 we have
x=288/8
x=$36
Which is a function and not a function
Answer:
Function: A, C, F, H,I
NOT: B,D,E,G
Step-by-step explanation:
To be a function every x is only allowed to pair up with one y. If there's no repeated x's, then its a function. If x repeats, it has to have the same y as the first time it showed up. If a vertical line (up and down) touches a graph in more than one place, its NOT a function. Any y can partner up with however many x's it wants to, doesn't matter, its still a function. But to be a function ONLY ONE y for each x. Life's not fair.

Central angle BAC of circle A measures 20" radians. Arc BC has a length of 63.487 centimeters. What is the radius of the circle?
The radius of circle A is ✓ centimeters.
Answer:
r = 55.2 cm
Step-by-step explanation:
the arc length is calculated as
arc = circumference × fraction of circle
= 2πr × [tex]\frac{\frac{23}{20}\pi }{2\pi }[/tex] ( r is the radius )
given arc = 63.48π , then
2πr × [tex]\frac{\frac{23}{20}\pi }{2\pi }[/tex] = 63.48π ( cancel 2π on numerator/ denominator )
r × [tex]\frac{23}{20}[/tex] π = 63.48π ( divide both sides by π )
[tex]\frac{23r}{20}[/tex] = 63.48 ( multiply both sides by 20 to clear the fraction )
23r = 1269.6 ( divide both sides by 23 )
r = 55.2 cm

A sports analyst determines that the number of points scored in a basketball game is related to the number of shots taken during the game. The least-squares regression line is y = 5. 0 + 1. 2x, where y is the predicted number of points scored and x is the number of shots taken. In one game, a team takes 50 shots and the residual is –10. How many points were scored by this team in this game?
45
55
65
75
Answer:
65
Step-by-step explanation:
y= 5.0 + 1.2x
when x = 50
y = 5.0 + 1.2 x 50
= 5.0 + 60
= 65
The value of y is 65 when x = 50, or the number of points the team was scored was 65.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A sports analyst determines that the number of points scored in a basketball game is related to the number of shots taken during the game.
y= 5.0 + 1.2x
Plug x = 50
y = 5.0 + 1.2 x 50
= 5.0 + 60
= 65
Thus, the value of y is 65 when x = 50, or the number of points the team was scored was 65.

The probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.
What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event. The probability of an event can not be more than the number 1.
John is playing a game of darts. In this game of dart,
The probability that he throws a dart into the center of the dart board (the Bull’s eye) is 1/10. The probability that he throws the dart into the 10-point ring is 3/10.The probability that he either hits a Bull’s eye or scores 10 points is equal to the sum of the probability he hits the bull's eye and the probability that he throws the dart into the 10-points ring.
Let, the probability that he either hits a Bull’s eye or scores 10 points is P. Thus,
[tex]P=\dfrac{1}{10}+\dfrac{3}{10}\\P=\dfrac{4}{10}\\P=\dfrac{2}{5}[/tex]
Hence, the probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.

If the circumference of a circle is increased by 40%,
then the area of the circle is increased by
A. 18%. B. 20%. C. 40%. D. 96%.
Answer:
96%
Step-by-step explanation:
c=100=22/7D
D=7/22×100
get the radius and find the area
R=D/2
A=pi×r^2
repeat that assuming
C=140
get the area
find the %age
A2_A1=Area difference
A(diff)/A1×100=96.01%
[tex]r_{2}[/tex]Answer:
D) 96%
Step-by-step explanation:
let the circumference of circle be C = 2π[tex]r_{1}[/tex] and [tex]r_{1}[/tex] = [tex]d_{1}[/tex]/2
Initial radius (radius before increment) = [tex]r_{1}[/tex]
initial diameter (diameter before increment) = [tex]d_{1}[/tex]
Increasing the circumference of a circle other factors are constant except the radius which can be used to find the diameter hence increasing the circumference of a circle is equivalent to increasing the diameter
area of the circle before increment [tex]A_{1}[/tex] = π[tex]r_{1}[/tex]²
[tex]A_{1}[/tex] = π × ([tex]d_{1}[/tex]/2)²
[tex]A_{1}[/tex] = π[tex]d_{1}[/tex]²/4
Increment of circumference results to increment of only the diameter
diameter after increment by 40%, [tex]d_{2}[/tex] = 1.4[tex]d_{1}[/tex]
1.4 represents increment by 40%
radius after increment [tex]r_{2}[/tex] = [tex]d_{2}[/tex]/2 = 1.4[tex]d_{1}[/tex]/2 = 0.7[tex]d_{1}[/tex]
area after increment, [tex]A_{2}[/tex] = π[tex]r^{2} _{2}[/tex]
[tex]A_{2}[/tex] = π(0.7[tex]d_{1}[/tex])²
[tex]A_{2}[/tex] = π × 0.49[tex]d_{1}[/tex]²
Change in area = [tex]A_{2}[/tex] - [tex]A_{1}[/tex]
[tex]A_{2}[/tex] - [tex]A_{1}[/tex] = π × 0.49[tex]d_{1}[/tex]² - π [tex]d_{1}[/tex]²/4
[tex]A_{2}[/tex] - [tex]A_{1}[/tex] = π [tex]d_{1}[/tex]²(0.49 - ¼)
[tex]A_{2}[/tex] - [tex]A_{1}[/tex] = π [tex]d_{1}[/tex]²(0.49 - 0.25)
[tex]A_{2}[/tex] - [tex]A_{1}[/tex] = 0.24 π[tex]d_{1}[/tex]²
Percentage increment = ([tex]A_{2}[/tex] - [tex]A_{1}[/tex]/ [tex]A_{1}[/tex]) × 100
= ((0.24 π[tex]d_{1}[/tex]²)/(π[tex]d_{1}[/tex]²/4)) × 100
= (0.24 × 4 ) × 100
= 0.96 × 100
= 96 %

The students in Ms. Baca's art class were mixing yellow and blue paint. She told them that two mixtures will be the same shade if the blue and yellow paint are in the same ratio. How many different shades of paint did the students make?
Answer:
Two shades will be prepared.
Step-by-step explanation:
Ms Baca told the students that when two colors yellow and blue are mixed in the same ratio same shade is prepares.
From the table attached,
If A is a mixture of 1 part yellow and 2 parts of blue color,
Ratio of the colors = 1 : 2
If B is a mixture of 2 parts yellow and 3 parts of blue color,
Ratio of the colors = 2 : 3
If C is the mixture of 3 parts yellow and 6 parts of blue color,
Ratio of the colors = 3 : 6 = 1 : 2
If D is a mixture of 4 parts yellow and 6 parts of blue color,
Ratio of the colors = 4 : 6 = 2 : 3
If E is a mixture of 6 parts yellow and 9 parts of blue color,
Ratio of the colors = 6 : 9 = 2 : 3
Therefore, mixtures A, C will create the same shade while mixtures B, D, E will be of same shade but different from A and C.
Two shades of the paints will be made by the students.
Use the angle relationship in the figure below to solve for x. Assume that line A and line B are parallel, line C is a transversal and the given angles are given in
degrees
AC
4x+29
12x+55
B
Answer:
x = 6
Step-by-step explanation:
The 2 angles given are same- side interior angles and are supplementary, thus
4x + 29 + 12x + 55 = 180, that is
16x + 84 = 180 ( subtract 84 from both sides )
16x = 96 ( divide both sides by 16 )
x = 6
