Answer 1

Answer: Let's plug the given value is in the formula : ${ V }_( cylinder )=\quad \pi { r }^( 2 )h$

First cylinder : ${ V }_( cylinder1 )=\quad \pi { 8 }^( 2 )21=\pi \cdot 64\cdot 21=1344\pi \quad { cm }^( 3 )$

Second cylinder : ${ V }_( cylinder2 )=\quad \pi { 11 }^( 2 )45=\pi \cdot 121\cdot 45=5445\pi \quad { cm }^( 3 )$

$5445-1344=4101\n \n 4101\pi \quad { cm }^( 3 )$

Answer is D

write a fraction with a decimal value between 1/2 ans 3/4. Write both the fraction and the equivalent decimal.

Answers

1/2 can also be written as 4/8
3/4 can be written as 6/8
5/8 is between 4/8 and 6/8
the equivalent decimal of 5/8 is .625

1/2 = 4/8 = 0.5
3/4 = 6/8 = 0.75
therefore, a fraction between 1/2 and 3/4 is 5/8

Make g the subject of the formula 3e + 4g = 7 + 9e

Answers

Answer:

g = 7 + 9e - 3e /4

Step-by-step explanation:

3e + 4g = 7 + 9e

Subtract 3e from both sides to eliminate 3e on the left side

3e - 3e + 4g = 7 + 9e - 3e

4g = 7 + 9e - 3e

Divide both sides by 4 to isolate g

4g/4 = 7 + 9e - 3e /4

g = 7 + 9e - 3e /4

Answer:

g=(7+9e-3e)/4

Step-by-step explanation:

3e+4g=7+9e

4g=7+9e-3e

g=(7+9e-3e)/4

Robert is making 5 batches of lemonade. Each batch requires 2 1\3 quarts of water. How much water will Robert need?
Express your answer in simplest form.

A.10 1\3
quarts

B.10 2\3
quarts

C.11 1\3
quarts

D.11 2\3
quarts

Answers

2 1/3 quarts per batch, and five batches, so you multiply 2 1/3 x 5.

2 1/3 = 7/3 and 5 x 7/3 = 35/3 which simplifies to 11 2/3, so D. is the answer.

If you would like a more detailed answer just ask.
