Answers

Answer 1

Answer: if the R is 5.2 and the V 713.21 it

8.4

use the formula

h=V/pi*R^2

so V=713.21/

5.2*3.14=16.328^2
so 16.328*2=32.56

713.21/32.56=21.9/2=10.4-2=8.4

Write an expression for the calculation subtract the difference of 20 and 13 from 70.

Answers

so subtract the diffference of 20 and 13 from 70
so first we find the difference and then subtract that from 70
use parenthases so
difference of 20 and 13 is equal to (20-13)
subtract that from 70
70-(20-13)
so you would do the pemdas and get 7 for the inside parethasees then do
70-7=63

equation is 70-(20-13)

70-(20-13)

A car 12.8 feet long. Jane uses a scale of 1 in. to 2 ft. for making a model of a car. How long is her car model.

the total length of her car model should be 6.4

The total length of her car model should 6.4 in. If you change the 2 ft into inches, the ratio becomes 1in. to 24in. Change the 12.8ft. to in. and get 153.6in. (by multiplying by 12) divide 153.6in. by 24in. and get 6.4in.

The quotient of a number and -9 increased by 10 is 11.Translate the sentence into an equation. then find the number that is described in the sentence.
I would like you to use the two-step equation process please.

Answers

so the division of a number and -9 or
x/-9

+10=11 or

(x/-9)+10=11
subtract 10 from both sides
x/-9=1
multiply both sides by -9
x=-9

Your equation would look like this . . .

n/-9 + 10 = 11

*solve by subtracting 10 from both sides, and then multiplying both sides by -9

n = (11 + 10)*-9 = -9

n = -9
