ok the equation  in finding the volume of a come is

V= \pi r^2 \frac{h}{3}

step 1: plugin

\pi =3.14

3.14 x 6^2 x 11/3

3.14x 36 x 11/3 =   (6/3 turns into a 2)

113.04x 11/3= 114. 48, when rounded, it's going to give you 415 in^3

Hong reads 9 3/4 chapters in 3 3/8 hours. What is the unit rate in chapters per hour? Write your answer as a fraction or a mixed
Sav [38]

The unit rate is: 2\frac{8}{9} chapters per hour

Step-by-step explanation:

Given

chapters read = 9\frac{3}{4} = \frac{39}{4}

Time = 3\frac{3}{8} = \frac{27}{8}

Unit rate is calculated by dividing the total chapters by total time

So,

Unit\ rate = \frac{\frac{39}{4}}{\frac{27}{8}}\\= \frac{39}{4} * \frac{8}{27}\\= 13 * \frac{2}{9}\\=\frac{26}{9}\\=2\frac{8}{9}

Hence,

The unit rate is: 2\frac{8}{9} chapters per hour

ASAP!!! ASAP!!! <br> What is the volume of the rock???
STatiana [176]

Answer:

10 cm³

Step-by-step explanation:

According to Archimedes, if we place an object in water, the rise of the water in mL will be the volume of the object in cm³.

Without the rock, the water measures 20 mL.

With the rock, the water measures 30 mL.

The change here is 30-20=10, so 10 cm³ is the volume of the rock.

Hope this helped!

Let f(x)=x2 -4x and g(x) =7-x find (fg)(2)
marta [7]

Step-by-step explanation:

f(x) = x² - 4

g(x) = 7 - x

= (fog)(2)

= x² - 4

= (7 - x)² - 4

= (7 - 2)² - 4

= 5² - 4

= 25 - 4

= 21

(fog)(2) = 21
