does 9/20 and 18/30 form a proportion

Answers

Answer 1

Answer:

No, they don't.

Step-by-step explanation:

I'm going to divide 18 by 9 and 30 by 20. If the quotients are the same, then we do have a proportion.

18 ÷ 9 = 2

30 ÷ 20 = 1.5

The quotients aren't the same. Same thing if you convert the fractions to decimals:

9 ÷ 20 = 0.45

18 ÷ 30 = 0.6

This means the two values do NOT form a proportion.

Hope this helps! Have a great day!

Answer 2

Answer:

No.

Step-by-step explanation:

9/20=18/30

9*30=20*18

120=360

If you would like to know how this works please do not hesitate to ask.

Empire star Terrence Howard was paid $1.25 * 105 per episode filmed in season one. If Empire filmed 12 episodes in the first season, how much total salary did Terrence Howard earn?

Answers

Answer:

Terrence would have earned $1575 dollars

Step-by-step explanation:

First we multiply 1.25 by 105.

1.25 * 105 = 131.25

Next we multiply 131.25 by 12.

131.25 * 12 = 1575.

So, the answer is 1575.

Hope this helps! :)

Step-by-step explanation:

0.87          0.12

Hope this helps!

The two-way column relative frequency table is,

                                            Weekday                        Weekend  

Had an ice cream cone                0.29                              0.88                

Did not have an ice -                    0.87                               0.11            

cream cone  

          Total                                   1.00                                 1.00                        

What is two-way frequency table?

"It is a way to display frequencies for two categorical variables."

"One category is represented by rows and a second category is represented by columns."

Now, We need to find the column relative frequency table.

First we find the total of each column.

                                        Weekday                        Weekend  

Had an ice cream cone             23                                45            

Did not have an ice -                 155                                 6            

cream cone  

          Total                               178                                51                

Now, divide each element of column by its respective total.

                                              Weekday                        Weekend  

Had an ice cream cone               23/178                               45/51                

Did not have an ice -                    155/178                                6/51                

cream cone  

          Total                                  178/178                               51/51

Therefore, the two-way column relative frequency table would be,

                                          Weekday                        Weekend  

Had an ice cream cone                0.29                              0.88                

Did not have an ice -                    0.87                               0.11            

cream cone  

          Total                                1.00                                 1.00

What is the slope of the line that passes through the points

)
(4,−2) and
(
24
,
−
17
)
?
(24,−17)? Write your answer in simplest form.

Answers

Answer:

-3/4

Step-by-step explanation:

Given the coordinates (4, -2) and (24, -17), we are to find the slope of the line passing through the points

Slope = y2-y1/x2-x1

Slope = -17-(-2)/24-4

Slope = -17+2/20

Slope = -15/20

Slope = -3/4

Hence the required slope is -3/4

Two equivalent fractions for 2/3

B) x/5 = 8 — 1) Multiple by 5

C) 3 = -x/5 — 2) Multiple by -5

D) 7 = -5x — 4) Multiple by -1/5


Explanation:

A:
5x = 0.4

5x • 1/5 = 0.4 • 1/5

x = 2/25 or 0.08


B:
x/5 = 8

x/5 • 5 = 8 • 5

x = 40


C:
3 = -x/5

3 • -5 = -x/5 • -5

-15 = x

x = -15


D:
7 = -5x

7 • -1/5 = -5x • -1/5

-7/5 = x

x = -7/5 or -1.4

m = -40/-2
m = 20
