Answer:
C = 4pi or approximately 12.56
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
C = 2*2*pi
C = 4pi
If we approximate pi by 3.14
C = 12.56
The perimeter of a triangle has the formula 2l + 2w. Since the length is twice as long as the width, l = 2w. We use this equations to two possible perimeters, 90 and 120 feet.
P = 90 feet
90 = 2(2w) + 2w
90 = 6w
w = 15 feet
P = 120 feet
120 = 2(2w) + 2w
120 = 6w
w = 20
Thus, the range of w is from 15 to 20 feet. The answer is <span>15 ≤ w ≤ 20</span>

Which ones you need help with? All of it?
Step-by-step explanation:
Around 4 times, maybe 3
Step-by-step explanation:
there's 2 red 3s and there's 52 cards in a deck. so u have a 2/52 chance to get a red 3 so its about a 4/104 chance to get a red 3 if u draw 1 card 100 times
-12x⁸y⁸ ÷ 3x⁴y².
Applying laws of indices. When you divide same base, you subtract the powers.
= (-12/3)x⁸⁻⁴y⁸⁻²
= -4x⁴y⁶
