A table is in the shape of a regular pentagon with a side length of 3 feet and an

ehidna [41]

Answer:

15.5 ft²

Step-by-step explanation:

The area (A) of a regular polygon is calculated as

A = $\frac{1}{2}$ pa ( p is the perimeter and a the apothem )

Here side of regular pentagon is 3 ft, thus

perimeter = 5 × 3 = 15, so

A = 0.5 × 15 × 2.06 ≈ 15.5 ft ( to the nearest tenth )

A unicycle travels 50 feet. If the radius of the tire is 24 INCHES, how many times does the tire rotate? A) about 8 times B) abo

Pie

The total distance traveled by cycle = 50 * 12 = 600 inch
1 complete rotation measures = 2 * 3.14 * 24 = 150.72 inch

Total rotation = 600 / 150.72
= approx. 4

I need the answer please. Because I think i got mine wrong

Gekata [30.6K]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

• $a^{-m}$ ⇔ $\frac{1}{a^{m} }$

• $a^{0}$ = 1

• $a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

Given

(a)

$8^{-2}$ = $\frac{1}{8^{2} }$

(b)

$\frac{1}{3^{-3} }$ = 3³

(c)

$6^{-12}$ × $6^{8}$ × $6^{0}$

= $6^{(-12+8)}$ × 1

= $6^{-4}$

= $\frac{1}{6^{4} }$
