A rate often involves time: e. g., 33 feet per second; also, we are finding the ratio of one type of measurement with respect to another: distance and time.

A proportion is often the ratio of different measures of the same thing:

e. g. 5 apples
------------
7 apples

To find the answer of this problem, we need to distibute and multiply all of the numbers with each other.

2x * x + 2x * 1 + 9 * x + 9 * 1
= 2x^2 + 2x + 9x + 9
= 2x^2 + 11x + 9

The answer would be the first option.

Hope this helps!

Use your equation from Exercise 6 to find m when n=40

Andreyy89

Answer:

=4/5(N+7)N

Step-by-Step Explanation:

We move all terms to the left:

-(4/5(N+7)N)=0

Domain of the equation: 5(N+7)N)!=0

N∈R

We multiply all the terms by the denominator

-(4=0

We add all the numbers together, and all the variables

=0

N=0/1

N=0

Step-by-step explanation:

Here is the complete question

Jenny used plastic cone shaped cups to serve punch. The cups were 6 inches in diameter and 5 inches tall. What was the volume of each cup?

Volume of a cone = $\frac{1}{3}$ πr²h

π = 22/7

Radius = diameter / 2 = 6 /2 = 3 inches

(1/3) x (3^2) x (22/7) x 5 = 47.14 in³

<h3>Question 1 ~</h3>

$log_{x}(64) = 2$

${x}^{2} = 64$

$x = \sqrt{64}$

$x = \sqrt{8 \times 8}$

$x = 8$

<h3>Question 2 ~</h3>

$log_{2}(x) = 5$

$x = 2 {}^{5}$

$x = 32$
