Solve the inequality 5(2h+8)<60

Bezzdna [24]

Answer and Step-by-step explanation:

$Greetings!$

$Let's~answer~your~question!$

$First, ~let's~ work~ on ~the~ left~ hand ~side~ of ~your ~inequality,~ the~ 5(2h+8)~This\\ means,~ for~ instance, ~to ~see ~if ~it ~can~ be ~simplified ~at~ all.~Multiply~ h ~and~ 2$

$The~ answer~ is~ h$

$2\times h~ evaluates~ to~ 2h$

$2\times h+8 ~evaluates~ to~ 2h+8$

$Multiply ~5~ by~ 2h+8$

$we ~multiply~ 5~ by~ each ~term ~in~ 2h+8 ~term ~by~ term~and~we~use~distributive~\\property.$

$Multiply ~5 ~and~ 2h$

$5\times2h=10h$

$Multiply~ 5 ~and ~8$

$5 \times 8 = 40$

The area of a circle is 9π in². What is the circumference, in inches? Express your answer in terms of \piπ

dangina [55]

Answer:

$6\pi$ in

Step-by-step explanation:

The formula to find the area of a circle: $\pi r^{2}$ , where $r$ is the radius.

The formula to find the circumference (perimeter) of a circle: $2\pi r$ , where $r$ is the radius.

1) To find the circumference of the circle, we need to find the radius ( $r$ ) first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.

$9\pi =\pi r^2$

Cancel the $\pi$ by bringing it to the other side.

$9 =\pi r^2$ ÷ $\pi$

$9 = r^2\\\sqrt{9} = r\\3 = r$

2) Find the circumference of the circle by using the formula, $2\pi r$ .

= $2*\pi *3$

= $6\pi$ in

Jake's water bill is $24.40 per month plus $2.20 per ccf (hundred cubic feet) of water. What is the maximum number of ccf Jake c

siniylev [52]

Answer:the maximum number of ccf Jake can use if he wants his bill to be no more than $58.00 is $15.3

Step-by-step explanation:

Let x represent the number of ccf of water that Jake uses in a month.

Jake's water bill is $24.40 per month plus $2.20 per ccf (hundred cubic feet) of water. This means that if she uses x ccf of water in a month, her total water bill would be

24.40 + 2.2x

Therefore, the maximum number of ccf Jake can use if he wants his bill to be no more than $58.00 would be

24.40 + 2.2x ≤ 58

2.2x ≤ 58 - 24.4

2.2x ≤ 33.6

x ≤ 33.6/2.2

x ≤ 15.3

In the diagram ABC is equal to DEC what is the value of x?

Hatshy [7]

$\begin{gathered} \frac{25}{5}=\frac{18-x}{x} \\ 25x=(18-x)\times5 \\ 25x=90-5x \\ 25x+5x=90-5x+5x \\ 30x=90 \\ \frac{30x}{30}=\frac{90}{30} \\ x=3 \end{gathered}$
