Answer:
5/12
Step-by-step explanation:
Given that:
Ratio of Red to white marbles = 7 to 5
Total = (7 + 5) = 12
Number of red marbles = 7
Number of white marbles = 5
Hence, fraction of white marbles = (number of white marbles / total number of marbles)
Fraction of white marbles = 5/12
4 quarts per gallon
<span>10 gallons: 4x10 = 40 quarts. </span>
<span>Add the 11 quarts to get 51 quarts. </span>
<span>51 divided by 3 = 17 quarts, or 4 gallons + 1 quart.</span>
Answer:
72.96
Step-by-step explanation:
Let the first circle's radius be r and quarter circle's radius be R
Area of circle = π
= 3.14 × 8 × 8
= 200.96
Area of quarter circle = π/4
= 3.14 × 16 × 16
= 803. 84/4
=200.96
Area of shaded portion = (Area of Quarter circle - Area of semi-circle ACD - Area of triangle ABC) + (Area of the circle - Area of semi-circle ACD - Area of triangle ABC)
Area of Semi-circle = Area of the circle divided by 2
= 100.48
Area of triangle =
=
= 64
Therefore, The area of shaded portion= (200.96-100.48-64) + (200.96 - 100.48 - 64)
= 36.48 +36.48
=72.96
