Answer:
18
Step-by-step explanation:
3 x 6 = 18
you just need to plug in the value for x
A) The shaded region is that portion of the rectangle that is not in the circle. You need the formulas for the area of a rectangle and a circle.
Area of rectangle = length*width
Area of circle = (π/4)*diameter²
b) The figure shows the width of the rectangle is 14 ft, the same as the diameter of the circle. The length of the rectangle is shows as 21 ft. The shaded area is the difference ...
Shaded Area = Area of rectangle - Area of circle
Shaded Area = (21 ft)*(14 ft) - (π/4)*(14 ft)²
Evaluating this expression, we have
Shaded Area ≈ 294 ft² - 153.9 ft² = 140.1 ft²
The answer is <u>143 miles.</u>
<h3>
EXPLANATION</h3>
The ratio between Dory's miles and Karly's miles is 11:1. This means that we need to <em>divide 156 by 12, </em>which is <u>13.</u>
Because Dory's miles make up 11/12 of the total miles, we need to take 1/12 (which is 13) from the 156 to get the final answer of <u>143 miles.</u>
Answer:
3, -8 , 11.
Step-by-step explanation:
f(x) = (x - 3)(x + 8)(x - 11)
Finding the zeros:
(x - 3)(x + 8)(x - 11) = 0
x - 3 = 0 gives x = 3.
x + 8 = 0 gives x = -8.
x - 11 = 0 gives x = 11.
