What is the value of 3(4(-2)+5x3)-2(7(-2)-3x3)
Answer: 67
Answer:
Half Life
Step-by-step explanation:
Cells decay by half of how much they decayed last time. This is an example of exponential decay.
Answer:
60.79 square yards.
Step-by-step explanation:
d = 2r; d = 8.8.
8.8 = 2r
r = 8.8 / 2
r = 4.4 yards.
Since we now have the radius, we can find the area of the circle, which can be found using πr^2, or 3.14 * r^2.
4.4^2 * 3.14 = 19.36 * 3.14 = 60.7904.
Since the question tells us to round to the nearest hundredth, our final answer will be 60.79 square yards.
Hope this helps!
