What is the exact volume of a sphere with a diameter of 18 cm? ______ cm3

1 answer:

4 0

The formula to find the volume of a sphere is: V= $\frac{4}{3} \pi r^{3}$
Since the diameter is 18 cm, so the radius is equal to r=18/2 = 9
Now we replace r by it's value, so we get:
$\frac{4}{3} \pi 9^{3}$
$\frac{4}{3} \pi 729$
$972 \pi$
And we get approximately $3053.63 cm^{3}$
Hope this Helps :D

Elmer started out with$103 in his bank account .he spent $4 per week at the cafeteria for snacks.what is the slope (m) for this

pochemuha

Answer:

The equation is $y=-4x+103$

The slope is m=-4

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

y is the amount left in the saving account

x is the number of weeks

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

The slope is equal to

$m=-\$4\ per\ week$ --> is negative because is a decreasing function

The y-intercept or initial value is

$b=\$103$

substitute

$y=-4x+103$

A pallet of floor tiles contains 40 cases of tiles and the yard has 10 complete pallets of tile. If you remove 180 cases for one

poizon [28]

Answer:

220 cases

Step-by-step explanation:

Each pallet contains 40 cases of tiles.

The yard has 10 complete pallets.

The total number of cases of tiles is therefore:

40 * 10 = 400 cases

If 180 cases are removed for the customer, then the number of cases of tiles remaining is:

400 - 180 = 220 cases

220 cases of tiles will be remaining.

T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released. The a

il63 [147K]

Answer:

The same number of tickets was sold on the fourth day and tenth day.

Step-by-step explanation:

Given, T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released.

The average rate of change in a function with respect to the independent variable gives the value of change in a particular period.

If average rate of change in T(d) for the interval d = 4 and d = 10 is is 0 , that means nothing has been changed in the number of tickets sold on 4th day and 10th day after the film release.

Hence, the correct statement is "The same number of tickets was sold on the fourth day and tenth day."
