Step-by-step explanation:

Answer: 2, 8, 96cm^2, 35 miles

What we know:

How to solve:

    By using our knowledge of ratios and substitution, we can solve these problems.

First problem

Set up ratio                                                             7.5:15

Find GCF                                                                (7.5:15)/7.5

Simplify                                                                   1:2

Solution:                                                                  2  

Second problem

Set up equation                                                     (x/10) = (6/7.5)

Rewrite                                                                   (x/10) = (60/75)

Simplify                                                                   (x/10) = (4/5)

Common denominator                                          (x/10) = (8/10)

Isolate variable                                                      [(x/10) = (8/10)]*10

Simplify                                                                    x = 8

Solution:                                                                  8

Third Question

where x represents the new width, y represents the new length, and A represents the new area.

Set up equation                                                    A = xy

Substitute                                                              A = (2*4)(2*6)

Simplify                                                                  A = (8)(12)

Simplify                                                                  A = 96

Solution:                                                                96 cm^2                                                      

Fourth Question

Where x represents the unknown length in miles

Set up equation                                                    (21:3) = (x:5)

Rewrite in fraction form                                        [(21/3)] /3 = (x/5)

Simplify                                                                   (7/1) = (x/5)

GCF                                                                        5(7/1) = (x/5)

Isolate variable                                                       [(35/5) = (x/5)]*5

Solution:                                                                  35 miles = x

Problem 1:

If the scale factor is 2, then the area of a square with the side measurement of 7.5 units should be (due to areas being squared) 1/2^2 of the square with the side measurement of 15 units. Let's solve this:

(1/2^2)(15*15) = (7.5*7.5)

(1/4)(15^2) = (7.5^2)

225/4 = 56.25

56.25 = 56.25

Therefore, a scale factor of 2 is correct.

Problem 2:

If x = 8, then 8/10 should equal 6/7.5. Let's solve this:

when x = 8:

8/10 = 6/7.5

0.8 = 0.8

Therefore, x = 8 is a correct solution.

Problem 3:

If a scale factor of 2 creates the new area of 96 cm^2, then the old area of (6*4) should be (due to areas being squared) 1/2^2 of the new area. Let's solve this:

(1/2^2)(96) = (6*4)

(96/4) = 24

24 = 24

Therefore, the new area is 96 cm^2.

Problem 4:

If the houses are 35 miles apart, then 3 in./21 mi. should be equal to 5 in./35 mi. Let's solve this:

(21/3) = (35/5)

7 = 7

Therefore, the houses are 35 miles apart.

Answer:

9 laps or 3600 meters.

Step-by-step explanation:

First you want to find who has ran the furthest and the least distance.

So we have Rory ran the most with 14 laps or 5600 meters and Daniel who ran the least with 5 laps or 2000 meters.Next we subtract becuase when you say to "find the difference" it means to subtract.We subtract  if you want to find the laps we do 14-5 and if you want to find the number of meters we do 5600-2000.

Answer:

15.21= 15.2 when rounded

Step-by-step explanation:

the formula for finding the area of a circle with the diameter is
A= 1/4 × π ×d^2

Answer:

15.21

Step-by-step explanation:

In order to find the area, you must find the radius first.

The diameter (4.4) divided by 2 = radius (2.2)

The area of a circle is pi times the radius squared ([tex]A = \pi r^{2}[/tex]).

In this situation, r, or radius =2.2.

[tex]A = \pi 2.2^{2}[/tex]

[tex]\pi[/tex][tex]2.2^{2}[/tex]= the area, 15.2053084434.

By rounding to the nearest hundredth, you get 15.21. The second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

Answer:

A: 4

Step-by-step explanation:

So first you can move the 2^-5 to the denominator, making the equation (2^2) (4^3) / (2^5) (2)

Then simplify the terms so you end up with (4)(64) / (32) (2)

Then multiply the denominator so you end up with (4) (64) / (64)

Since both the denominator and numerator have 64, those cancel out leaving you with 4

Answer:

A

Step-by-step explanation:

I didn't learn jrf, but I believe that it is the amount of females that watch action movies divided by the total amount of females.

Amount of females who watch action movies= 99

Total females= 250

So, A seems correct.

The joint relative frequency of being male and attending a drama film, divide 124 by 229.

The number of times an event occurs divided by the total number of events occurring in a particular scenario is described as relative frequency.

Two things must be understood in order to compute the relative frequency:

               Action           Drama              Total

Male           105                124                 229

Female       99                 151                  250

Total           204               275                 479

The joint relative frequency is the frequency in a given category divided by the total number of data values.

Here, The total number of males = 229

and, the number of males that like drama = 124

To calculate the joint relative frequency of being male and attending a drama film, divide 124 by 229.

Step-by-step explanation:

−5x − 25 = 78

Step 1: −5x − 25 − 25 = 78 − 25        WRONG

- 5x - 25 = 78

- 5x - 25 + 25 = 78 + 25

- 5x                  = 103

x = - 103/5

x = - 20,6

Answer:

Step-by-step explanation:

−5x − 25 = 78

Step 1: −5x − 25 − 25 = 78 − 25  <== this is where the error was made.

Step 2: −5x = 53

Step 3: = −5x/−5=53/−5

Step 4: x = −53/5

Right steps:

−5x − 25 = 78

Step 1: −5x − 25 + 25 = 78 + 25

Step 2: −5x = 103

Step 3: −5x/−5 = 103/−5

Step 4: x = 103

Step 1 was where the error was, because she subtracted 15 from both sides instead of adding 15, so they cancelled out.

Answer:

a. the first and last one

b. the second and third one

Step-by-step explanation:

a. 11x-3x-10x=18x, so the first one is definitely the answer. If you look at the last one, you can see that 10x+8x also equals 18x. The other options do not equal 18x, so those can be eliminated.

b. If you distribute the 3 outside of the parentheses, you can see that the expression 3(1+3y) equals 3+9y (because 3*1=3 and 3*3y=9y). So, the third one can be determined to be one of the answers. We can see that the second one also simplifies to be 3+9y, so this one can also be determined to be the answer. The other ones can be eliminated because they do not equal 3+9y.

Hope this helped! :)

Answer:

a) 18x and 8x + 10x

b) 3 × 1 + 3 × 3y and 3 + 9y

Step-by-step explanation:

11x - 3x = 8x and then 8x + 10x is left. The answers are 18x and 8x + 10x.

3 × 1 is 3 and 3y × 3 is 9y.

Answer:

The number b is bigger than the number a by 1/4 of a.

Step-by-step explanation:

If the number a is smaller than the number b by 1/5 of b, then

a + 1/5b = b.

Thus,

a= b - 1/5b= 4/5,

b= 5/4 a.

Consider the Expression b=5/4a:

b=5/4a= 4/4a+ 1/4a= a +1/4a

This gives that the number b is bigger than the number a by 1/4 of a.
