Could be: 6*3 9*2 18*1

Explanation: Rectangles have one side longer than the other. To get the area of a rectangle you do Length*Width. So I divided 18 by whole numbers to get multiple choices for you.

Which of the following is the solution set to the inequality −25x+14>20?

Bezzdna [24]

Answer:

Option C. $x < -15$

Step-by-step explanation:

<u><em>The correct inequality is</em></u>

$-\frac{2}{5}x+14 >20$

Solve for x

subtract 14 both sides

$-\frac{2}{5}x+14-14 >20-14$

$-\frac{2}{5}x >6$

Multiply by -1 both sides

$\frac{2}{5}x < -6$

Multiply by 5/2 both sides

$x < -6(\frac{5}{2})$

$x < -15$

Factor completely x^2 − 10x + 25.

Olenka [21]

The answer is a.
x^2 -10x+25 = x*x-2*5*x+5*5 => (x-5)(x-5)

Kevin cuts lawns during the summer months. He charges $10 plus $5 per hour. The algebraic model is C = 5h + 10, where C represen

Oxana [17]

Answer:

$\begin{center}\begin{tabular}{ c c c }Hours(h) & Total Cost(C) \\ 1 & 15 \\ 2 & 20 \\ 3 & 25 \\ 4 & 30 \\ 5 & 35 \end{tabular}\end{center}$

Step-by-step explanation:

Given that:

Kevin charges $10 plus $5 per hours

C = 5h + 10

To find:

The table of values for hours worked from 1 to 5.

Solution:

First of all, let us put h = 1 in the given equation:

C = 5 \times 1 + 10

C = 5 + 10 = $15

Now, let us put h = 2 in the given equation:

C = 5 \times 2 + 10

C = 10 + 10 = $20

Now, let us put h = 3 in the given equation:

C = 5 \times 3 + 10

C = 15 + 10 = $25

Now, let us put h = 4 in the given equation:

C = 5 \times 4 + 10

C = 20 + 10 = $30

Now, let us put h = 5 in the given equation:

C = 5 \times 5 + 10

C = 25 + 10 = $35

So, the table becomes each row incrementing h by 1:

$\begin{center}\begin{tabular}{ c c c }Hours(h) & Total Cost(C) \\ 1 & 15 \\ 2 & 20 \\ 3 & 25 \\ 4 & 30 \\ 5 & 35 \end{tabular}\end{center}$

What is the EXACT volume of this composite figure?

mariarad [96]

Answer:

324π in.³

Step-by-step explanation:

The figure is a cone and a half sphere.

V = (1/3)πr²h + [(4/3)πr³]/2

V = (1/3)π(36 in.²)(15 in.) + (2/3)π(216 in.³)

V = [180π + 144π] in.³

V = 324π in.³
