Solve<span> A = bh for b. Since h is multiplied times b, you must divide both sides by h in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the </span>equation<span> by 2.</span>
Answer:
divied it
Step-by-step explanation:
s = standard version amount
h = high quality version amount
we know that there were 1090 downloads of the song, meaning s + h = 1090.
we also know that the total amount of MBs downloaded was 3353 MBs, and since the standard is 2.1 MBs and the high quality is 4.9MBs, then 2.1s + 4.9h = 3353.
A. To find the area of a circle you need to use the formula A= π r²
The radius (R) is half of the diameter . . . that's 6.5 cm .
r² = (
6.5)² = 42.25 cm²
Area = π r² = 42.25 π = <em>132.7 cm²</em>
B. Area of a rectangle is just (length) x (width).
Length = 12 cm
Width = 5 cm
Area = (12 cm) x (5 cm) = <em>60 cm²</em>
C. The shaded portion is the part of the circle that's NOT in the rectangle. So its area is (area of the circle) - (area of the rectangle)
Area = (132.7 cm²) - (60 cm²) = <em>72.7 cm²</em>
101.28-96 = 5.28
5.28/96 = 0.055
0.055 x 100% = 5.5%
