S = -2-4r. You can't simplify the expression past that.
Answer:
<u>The amount of interest earned is US$ 160 and none of the alternatives is correct.</u>
Step-by-step explanation:
Let's use the formula for calculating the interest in a simple interest problem, this way:
Interest earned = (Principal * Interest rate * time in years)
Replacing with the real values, we have:
Interest earned = (100 * 0.08 * 20)
Interest earned = 160
<u>The amount of interest earned is US$ 160 and none of the alternatives is correct.</u>
Answer:
100.48 cm³
Step-by-step explanation:
Volume of a cone, V = 1/3 * pi * r² * h
Radius, r = 4 cm ; h = 6cm
V = 1/3 * 3.14 * 4² * 6
V = 1/3 * 3.14 * 16 * 6
V = 3.14 * 16 * 2
V = 3.14 * 32
V = 100.48 cm³
Hence, the volume of the cone is 100.48 cm³
Answer:
B
Step-by-step explanation:
Area of the Rectangle = L*W
L = 25 cm
W = 14 cm
Area of the rectangle = 25 * 14
Area of the rectangle = 350
Area of the Triangle
Area = 1/2 B * H
B = 25
H = 11
Area = 1/2 *25 * 11
Area = 1/2 275
Area = 137.5
Area of the shaded part = 350 - 137.5
Area of the shaded part = 212.5
