I think the question is asking for the ratio to be simplified, if so then that's what the answer is.
Answer:
75
Step-by-step explanation:
12 : 50 :: 18 : x
In proportion, Product of extremes = Product of means
12 * x = 50*18
[tex]x =\frac{50*18}{12}=\frac{50*3}{2}[/tex]
x = 25 * 3 = 75

Step-by-step explanation:
∠VMC=180-90-48
=42
∠PMV=180-22-90-42
=26
5/sin48=VM/sin90
VM=6.728( correct to three decimal places)
6.728/sin22=PV/sin26
PV=7.873( correct to three decimal places)

0.606 0.606 0.631 0.631
0.584 0.584 0.592 0.592
0.644 0.644 0.597 0.597
0.639 0.639 0.607 0.607
0.564 0.564 0.673 0.673
Answer:
[tex]s = 0.0394[/tex]
Step-by-step explanation:
Given:
0.612 0.523 0.606 0.631 0.584 0.592 0.644 0.597 0.639 0.607 0.564 0.673
Required
Calculate the sample standard deviation
First, calculate the mean
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\bar x = \frac{0.612 +0.523 +0.606 +0.631+ 0.584 + 0.592+ 0.644 +0.597 +0.639 +0.607 +0.564+ 0.673}{12}[/tex]
[tex]\bar x = \frac{7.272}{12}[/tex]
[tex]\bar x = 0.606[/tex]
The sample standard deviation is then calculated using:
[tex]s = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
[tex]\sum (x - \bar x)^2 = (0.612 -0.606)^2+(0.523 -0.606)^2+(0.606 -0.606)^2+(0.631 -0.606)^2+(0.584 -0.606)^2+(0.592 -0.606)^2+(0.644 -0.606)^2+(0.597 -0.606)^2+(0.639 -0.606)^2+(0.607 -0.606)^2+(0.564 -0.606)^2+(0.673 -0.606)^2[/tex]
[tex]\sum (x - \bar x)^2 = 0.017098[/tex]
So, we have:
[tex]s = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
[tex]s = \sqrt{\frac{0.017098}{12-1}}[/tex]
[tex]s = \sqrt{\frac{0.017098}{11}}[/tex]
[tex]s = \sqrt{0.00155436363}[/tex]
[tex]s = 0.0394[/tex] -- approximated

12 of the students in the art class like to draw animals these 12 students make up 24% of the art class how many students are in the art class
Answer:
50 students in total or X=50
Step-by-step explanation: 12 is 24% of X
We can make this into a box-like figure
12 24
X 100 X is the missing number
We then multiply 12 by 100 which equals to 1,200.
We then divided the 1,200 by 24, this results in your X which equals to 50.

HELP ME Write and solve a proportion to find y.
Given:
A figure of dilation and the center of dilation is O.
To find:
The value of y.
Solution:
The distance between center and vertex of image (d') is proportional to the distance between center and the corresponding vertex of original figure (d).
[tex]d'\propto d[/tex]
[tex]d'=kd[/tex]
[tex]\dfrac{d'}{d}=k[/tex]
Where, k is the scale factor or constant of proportionality.
So, the scale factor for the given dilation is
[tex]k=\dfrac{OB'}{OB}[/tex]
[tex]k=\dfrac{36}{16}[/tex]
[tex]k=\dfrac{9}{4}[/tex]
We know that,
[tex]k=\dfrac{\text{Side length of image}}{\text{Corresponding side length of original figure}}[/tex]
[tex]\dfrac{9}{4}=\dfrac{A'C'}{AC}[/tex]
[tex]\dfrac{9}{4}=\dfrac{27}{y}[/tex]
[tex]9\times y=27\times 4[/tex]
Divide both sides by 9.
[tex]y=\dfrac{27\times 4}{9}[/tex]
[tex]y=3\times 4[/tex]
[tex]y=12[/tex]
Therefore, the value of y is 12.
Caroline and Chase are working on math homework. They decide to race to see who can finish first. Caroline is on number 12 and can solve 1 math problem in 1.5 minutes. Chase is on number 16 and can solve 1 math problem in 2 minutes. How many minutes will it take before they are on the same problem?
Answer:
It will take 24 minutes before they are on the same problem.
Step-by-step explanation:
Caroline is on number 12 and can solve 1 math problem in 1.5 minutes.
Per minute, she solved [tex]\frac{1}{1.5} = \frac{2}{3}[/tex] of a problem. So, after t minutes, she will be on the problem:
[tex]Ca(t) = 12 + \frac{2t}{3}[/tex]
Chase is on number 16 and can solve 1 math problem in 2 minutes.
Per minute, he solved [tex]\frac{1}{2}[/tex] of a problem. So, after t minutes, he will be on the problem:
[tex]Ch(t) = 16 + \frac{t}{2}[/tex]
How many minutes will it take before they are on the same problem?
This is t for which:
[tex]Ca(t) = Ch(t)[/tex]
So
[tex]12 + \frac{2t}{3} = 16 + \frac{t}{2}[/tex]
[tex]\frac{2t}{3} - \frac{t}{2} = 4[/tex]
[tex]\frac{4t-3t}{6} = 4[/tex]
[tex]\frac{t}{6} = 4[/tex]
[tex]t = 24[/tex]
It will take 24 minutes before they are on the same problem.

.) Which ordered pair shows an equivalent ratio
of pounds to dollars?
(24,30)
(20,25)
(25, 20)
(40.36)
Answer:
I think (25, 20) is your answer. hope it helps.
The equivalent ratio to (5, 4) is (25, 20). Therefore, option C is the correct answer.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
The coordinates from graph are (5, 4), (10, 8), (15, 12) and (20, 16).
Equivalent ratios are ratios that can be simplified to the same value by dividing both the values by a common fraction.
Here,
(5, 4)=5(5, 4)=(25, 20)
(10, 8)=2(10, 8)=(20, 16)
(15, 12)=2(15, 12)=(30, 24)
(20, 16)
The equivalent ratio to (5, 4) is (25, 20). Therefore, option C is the correct answer.

A spinner has five equal portions colored orange, red, blue, yellow, and green. What are the odds against spinning a red or an orange?
Answer:
2/5
the denominator is five because it says that there is five equal portions of the spinner. The numerator is too because you are trying to find the odds of getting two colors
Sally collected 32 coins. The ratio of Sally’s coins to Bill’s coins is 4 : 7. If Sally and Bill each double the number of coins they have now, what is the ratio of Sally’s coins to Bill’s coins?
Answer:
64 S
----
112 B
Step-by-step explanation:
The number of coins Sally and Bill will be 64 and 112 and the ratio will remain the same.
What is the ratio?
It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that Salley collected 32 coins, the ratio of Sally’s coins to Bill’s coins is 4: 7, and Sally and Bill each double the number of coins they have now.
Suppose the number of coins that Sally and Bill will be 4x and 7x respectively.
If Sally has the 32 coins and if she doubles the coins she has 64.
4x = 64
x =16
Sally’s coins,
4x = 4 × 16 =64
Bill’s coins,
7x =7× 16 = 112
Thus, the number of coins Sally and Bill will be 64 and 112 and the ratio will remain the same.
