Answer:
Its D because 2×2×2 equals 8 and they are both minus and knowing - times - makes + so it becomes 8
ANSWER
5
EXPLANATION
The equation that expresses the approximate height h, in meters, of a ball t seconds after it is launched vertically upward from the ground is

To find the time when the ball hit the ground,we equate the function to zero.

Factor to obtain;

Apply the zero product property to obtain,


t=0 or t=5.1 to the nearest tenth.
Therefore the ball hits the ground after approximately 5 seconds.
Answer:
Ethan rollerbladed each day
kilometers.
Step-by-step explanation:
Given:
Ethan rollerbladed a total of 623 km over d days.
Now, to find the kilometers Ethan rollerblade each day.
Total number of distance rollerbladed = 623 km.
Total number of days = 
<u><em>As, Ethan rollerbladed each day the same distance.</em></u>
Now, to get the distance Ethan rollerbladed in each day we divide total number of distance rollerbladed by total number of days:


Therefore, Ethan rollerbladed each day
kilometers.
Answer:
p = 15/40
Step-by-step explanation:
Since the total number of marbles is 40, that is our size of the sample. there are 16 red ones on that sample, so the probability of extracting a red marble from the box is given by the ratio of successes divided the total number of marbles:
p = 15/40
