Answer: -83
Step-by-step explanation:
f(9)--22+20-9*(9)=-2-81=-83
100%-59%-=41%
41% divided by 94=0.44
59% divided by 6=9.83
9.83 divided by 0.44= 22.34. One of these 6 people would be 22.34 times as wealthy as one of these other 94 people.
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:
x=4
Step-by-step explanation:
1. isolate the variable by subtracting 7 on both sides: 4x=23-7
2. simplify: 4x=16
3. divide both sides by 4: x=16/4
4. simplify: x=4
The anwser is 90 because its 90 degree angle
