Translate the following word phrase into an algebraic expression: nine times five less than twice x.

bagirrra123 [75]

The given statement is "nine times five less than twice x".

So, twice of x can be written as 2x and nine times five is 9*5.

Now 9*5 less 2x means we need to take out 9*5 from 2x.

Hence, this statement will be converted into an algebraic expression as follows:

2x-9*5

Find the volume of this sphere.

Sholpan [36]

<h3>Calculate the volume of the sphere</h3>

To start finding the volume of this sphere, we get the following data:

π = 3
r = 2 ft²

To find the volume we apply the following formula:

$\boldsymbol{\sf{V= \dfrac{3}{4}\pi r^{2} }}$ , where

v = volume
π = pi
r = radius

We substitute our data in the formula and solve:

Substituting values into the equation

$\boldsymbol{\sf{V=\dfrac{3}{4}*3*(2 \ ft)^{3} }}$

Calculate exponent cubed

$\boldsymbol{\sf{V=\dfrac{3}{4}*3*8 \ ft^{3} }}$

Multiplying

$\boxed{\boldsymbol{\sf{V=32 \ ft^{3} }}}$

Therefore, the volume of the sphere is 32 ft³.
