Your dad is designing a new rectangular garden for your backyard. He has 20 feet of fencing to go around the garden. He wants the length of the garden to be 2 12 feet longer than the width. How long should he make the garden?

A 6 ¼ feet
B 6 feet
C 5 ½ feet
D 5 feet

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

\(\tt {1)\:a^{-b}}=\boxed{\tt \cfrac{1}{a^b}}\)

\(\tt 2)\: \cfrac{a^b}{a^c}=\boxed{\tt a^{b-c}}\)

\(\tt \tt 3)\:\cfrac{a^c}{b^c}=\boxed{\tt \left(\cfrac{a}{b}\right)^c}\)

Step-by-step explanation:

\(\tt {1)\:a^{-b}}\)

Apply the exponent:-

\(\boxed{\tt a^{-b}=\frac{1}{a^b}}\)

___________________

\(\tt 2)\: \cfrac{a^b}{a^c}\)

Apply the exponent:-

\(\boxed{\tt \cfrac{x^a}{x^b}=x^{a-b}}\)

___________________

\(\tt 3)\:\cfrac{a^c}{b^c}\)

Apply the exponent:-

\(\boxed{\tt \frac{x^a}{x^b}\:=\:x^{a-b}}\)

\(\tt \left(\cfrac{a}{b}\right)^c\)

Answer: 52.2

Step-by-step explanation:

Answer: X = 34

Angle F = 68

Angle G = 15

Step-by-step explanation: 2x+22=90

2x=68 divided by 2 on both sides, X = 34

Answer:

x = 34

Angle F = 75

Angle G = 15

Step-by-step explanation:

Complementary = 90°

2x+7+15=90

2x+22=90

2x = 64

x = 34

Angle F

2 * 34 + 7 = 75

Answer:

12

Step-by-step explanation:

Opposite sides of a rectangle share the same side measurements (based on the definition of a rectangle). This means that the perimeter is found as:

P(perimeter)= 2l + 2w

Let:

length (l) = 4

width (w) = 2

Plug in the corresponding numbers tot eh corresponding variables:

P = 2(l) + 2(w)

P = 2(4) + 2(2)

Simplify. First, multiply, then add:

P = (2 * 4) + (2 * 2)

P = (8) + (4)

P = 12

12 will be your perimeter.

~

Check. Since it is given that it is a rectangle, by definition of a rectangle, you will know that opposite sides are congruent, and therefore share the same measurements.

P = 2 + 2 + 4 + 4

P = (4) + (8)

P = 12

12 will be your perimeter.

Answer:

$4.94

Step-by-step explanation:

We can first solve this by turning this sales tax percentage into a decimal

\(8.6\% = 0.086\%\)

Now that we got that and your first answer of $57.40, we can multiply the two numbers.

\(0.086 \times 57.40 = 4.9364\)

That rounds to 4.94

\(\textrm {Volume of rectangular pyramid :}\)

\(\mathrm {Volume = \frac{1}{3} \times length \times width \times height}\)

\(\mathrm {Volume = \frac{1}{3} \times 9 \times 8 \times 9}\)
