15% of 8quarts and 90% of 8 quarts = x% of 16 quarts
0.15 x 8 quarts + 0.90 x 8 quarts
=1.2 quarts + 7.2 quarts
= 8.4 quarts
8.4 quarts/16 quarts
= (8.4)/(16)
= 0.525
= 52.5%
ONLY because the solutions are 50-50 we could have averaged the percentages (15 + 90)/2 = 52.5
Answer:
The radius is 5 in
Step-by-step explanation:
The area of a circle is given by the formula
A = pi *r^2
We know the area = 78.5 in^2 (volume would be in^3 area is in^2)
78.5 = 3.14*r^2
Divide each side by 3.14
78.5/3.14 = 3.14/3.14*r^2
25 = r^2
Take the square root of each side
sqrt(25) sqrt(r^2)
5 =r
the slope will be -6. the -3 -3 will be equal to -6
