1 answer:

6 0

1. The answer is letter b. four more than twice a number.
Given number = 2n + 4,
=> 2n = twice a number, n represents the unknown number
=> + = add or more than
=> 4 = four
So, this can be say as = twice a number more than 4 , or four more than twice a number.
Thus, the given equation’s answer is letter B. four more than twice a number
=> Four = 4
=> more than = +
=> twice a number = 2n
=> 4 + 2n, the same as 2n + 4

The question is below

Anna35 [415]

Answer:

12) A = 27

13) B = 36

14) C = 25

15) D = 30

Step-by-step explanation:

We need to complete the ratio tables

We are given:

Footballs 15 5 20 C D

Baseballs A 9 B 45 54

The table shows the ratio of footballs to baseballs.

We are given the ratio $\frac{Football}{Baseball}=\frac{5}{9}$

All other ratios will also be simplified to get $\frac{5}{9}$

12) Calculate A

Footballs = 15

Baseballs = A

Common ratio is 5/9, we need to find a number that multiplies by 5 to get 15, same number will be multiplied by denominator to get A.

We know that $\frac{5\times3}{9\times3}= \frac{15}{27}$

So, A = 27

13) Calculate B

Footballs = 20

Baseballs = B

Common ratio is 5/9, we need to find a number that multiplies by 5 to get 20, same number will be multiplied by denominator to get B.

We know that $\frac{5\times4}{9\times4}= \frac{20}{36}$

So, B = 36

14) Calculate C

Footballs = C

Baseballs = 45

Common ratio is 5/9, we need to find a number that multiplies by 9 to get 45, same number will be multiplied by numerator to get C.

We know that $\frac{5\times5}{9\times5}= \frac{25}{45}$

So, C = 25

15) Calculate D

Footballs = D

Baseballs = 54

Common ratio is 5/9, we need to find a number that multiplied by 9 to get 54, same number will be multiplied by numerator to get D.

We know that $\frac{5\times6}{9\times6}= \frac{30}{54}$

So, D = 30

Select the correct answer. Which equation represents the measure of the unknown angles?

Arisa [49]

C. x+x+10
Angles in a triangle add up to 180-50=130
130-10=120/2=x
x(60)+x(60)+10=130

The bumper car ride at the state fair has 2 red cars, 4 green cars, an for the ride and is assigned a the probability that both

ollegr [7]

Answer:

a) 3.6%

Step-by-step explanation:

The given question mixed up, below is the correct question:

The bumper car ride at the state fair has 2 red cars, 4 green cars, and 2 blue cars. Garth is first in line for the ride and is assigned a car at random. Patty is next in line and is randomly assigned a car. Find the probability that both events A and B occur. Express your answer as a percent. If necessary, round your answer to the nearest tenth.

Calculation:

Given that the state fair has 2 red cars, 4 green cars and 2 blue cars.

There are therefore 2+4+2 = 8 cars in total.

Probability that Events A occurs P(A) = $\frac{2}{8}$ = 4
