First, I'd like to say that this question is flawed because the diameter of the spool changes as you pull the line out. Some would argue it's negligible I suppose.
At any rate, assuming there's a magic spool where the diameter doesn't change, let's find the cicumference so we can find the length of one wrap around the spool.
circumference = 2*pi*r = 2 * pi * 4cm = about 25.133 cm
Now if it turns 16 times we'll have 16 times the circumference.
16 * (25.133 cm)
= 402.128 cm
Answer:
Step-by-step explanation:
slope m= (y2-y1) / (x2-x1) = 15-12 / 4-4 = 3/0 is undefined since we can not divide by 0
slope is undefined so the line is vertical
I’m pretty sure A is true <3
1 dozen = 12 apples.
3 apples cost 0.48, multiply that by 4 to get the price of 1 dozen.
0.48 x 4 = $1.92 per dozen.
Divide the total you can spend ( 3.84) by cost per dozen:
3.48 / 1.92 = 2
You can buy 2 dozen.
