If the amount of time is x seconds, then 15*x is the amount ran by one child and 6*x is the amount ran for the other child due to that they add 15 or 6 feet for each second. In addition, since they are 450 feet apart, 15x+6x=450=21x. Dividing both sides by 21, we get x=around 21.4 seconds. Since the mother is always between them, when those two meet is when the three meet. Therefore, she runs 20* around 21.4= around 428.57 feet
The answer for this question is 18
Answer:
f(-2) = 0.005
Step-by-step explanation:
f(x) = 1/8 x 5^x
f(-2) = When x in the function of f(x) is -2.
f(-2) = 1/8 x 5^-2
f(-2) = 1/8 x 0.04
f(-2) = 0.005
Use a calculator and divide
Area of the remaining countertop = original area - area of the hole.
<span>Original area = 3 feet * 5 feet = 15 sq ft. </span>
<span>Area of the circle = pi*0.5(D)^2 = 1.77 sq ft </span>
<span>Remaining area = 13.23 sq ft </span>
