Answer:

Volume of the sphere ( V ) = 1436.02 cm³

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the radius of the sphere r = 7 cm

Volume of the sphere

                  V = \frac{4}{3} \pi r^{3}

                 V = \frac{4}{3} \pi (7)^{3}

                 V = \frac{4}{3} X3.14 X (7)^{3} = 1436.02

                 V = 1436.02 cm³

Volume of the sphere

                  V = 1436.02 cm³

stellarik [79]

Answer:

$44

Step-by-step explanation:

First, find how much he was making originally:

Multiply the number of hours he worked by the amount he got per hour:

20(8)

= 160

Then, find how much he gets now:

24(8.50)

= 204

To find his total weekly pay increase, find the difference between them:

204 - 160

= 44

So, his total weekly pay increase is $44

Evelyn has $524.96 in her checking account. She must maintain a $500 balance to avoid a fee. She wrote a check for $32.50 today.
cupoosta [38]

A linear inequality to represent the algebraic expression is given as 492.46 - x ≥ 500

<h3>Linear Inequality</h3>

Linear inequalities are inequalities that involve at least one linear algebraic expression, that is, a polynomial of degree 1 is compared with another algebraic expression of degree less than or equal to 1.

In this problem, her minimum balance must not decrease beyond $500 or she will pay a fee.

where

  • x = withdrawals

The inequality to represent this can be written as

524.96 - 32.50 - x ≥ 500

Simplifying this;

492.46 - x ≥ 500

The linear inequality is 492.46 - x ≥ 500
