24 is 31.25% of what number? Prove your answer in the show your workbox.

FinnZ [79.3K]

Answer:

76.8

Step-by-step explanation:

1. We assume, that the number 31.25 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 31.25, so we can write it down as 100%=31.25.

4. We know, that x% equals 24 of the output value, so we can write it down as x%=24.

5. Now we have two simple equations:

1) 100%=31.25

2) x%=24

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=31.25/24

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 24 is what percent of 31.25

100%/x%=31.25/24

(100/x)*x=(31.25/24)*x - we multiply both sides of the equation by x

100=1.3020833333333*x - we divide both sides of the equation by (1.3020833333333) to get x

100/1.3020833333333=x

76.8=x

x=76.8

now we have:

24 is 76.8% of 31.25

The lines represented by the equations y = -X – 3 and

xz_007 [3.2K]

The equations y = -x -3 and 5y + 5x = -15 represents the same line option 'the same line' is correct.

<h3>What is linear equation?</h3>

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.

We have two equation of the line:

y = -x -3 and

5y + 5x = -15

From the equation 5y + 5x = -15:

Divide by 5 on the above equation:

y + x = -3

y = -x -3

The two equations y = -x -3 represents the same line.

Thus, the equations y = -x -3 and 5y + 5x = -15 represents the same line option 'the same line' is correct.

40 points | Sierra and Alek each have five cousins. Their ages are listed below.

faust18 [17]

Find the mean for both:

Sierra: 2 + 11 + 12 + 13 + 15 = 53

53/5 =10.6

Median is the middle value = 12

Alek: 9 + 11 + 11 + 12 + 13 = 56

56/5 = 11.2

Median = 11

A: The medians do not equal the mean.

B: Sierra's are more spread out, ( no identical ages and a greater range ).

C: Sierra's mean is less than Alek.

D. Sierra has an outlier (2).

The answer would be B

WILL MARK BRAINLIEST ANSWER!!!!!!! Quadrilateral KLMN is similar to quadrilateral WXYZ. Write a proportion that must be true for

snow_tiger [21]

Answer:

Since, In Quadrilaterals KLMN and quadrilateral WXYZ,

Sides Kl, LM, MN and NK are corresponding to the sides WX, XY, YZ and ZW respectively.

Also, If two shapes are similar the ratio of their corresponding sides must be same are in same proportion,

Here, Quadrilateral KLMN is similar to quadrilateral WXYZ,

Therefore,

$\frac{KL}{WX}=\frac{LM}{XY}=\frac{MN}{YZ}=\frac{NK}{ZW}$

Which is the required proportion that must be true for the given figure.
