7/8 + x = 1
subtract 7/8 from each side
x = 1-7/8
x = 8/8 - 7/8
x = 1/8
Workbook =x
1/4 3/5
x 5/5 (1 hour)
then x=(5/5 * 1/4):3/5
x= 5/20 * 5/3
x=1/4 *5/3
x= 5/12
Answer:
8
Step-by-step explanation:
It's clear that the ratio of the weight and cost is 1:2.
So when you increase the factor by 4 , the cost increases by 8.
That's all I can say, and I'm sure my answer is correct.
Either way. The probability of hitting the circle is:
P(C)=Area of circle divided by area of square
P(W)=(area of square minus area of circle divided by area of square
P(C)=(πr^2)/s^2
P(W)=(s^2-πr^2)/s^2
...
Okay with know dimensions, r=1 (because r=d/2 and d=2 so r=1), s=11 we have:
P(inside circle)=π/121 (≈0.0259 or 2.6%)
P(outside circel)=(121-π)/121 (≈0.9744 or 97.4%)
