Answer:
across the mibble to the down
Step-by-step explanation:
A) Divide the total height by the average height:
26.4 / 1.2 = 22 total boys.
B) Divide total feet by total time:
440 feet / 20 seconds = 22 feet per second.\
Because the submarine is diving the rate would become negative 22 feet per second.
The answer is -13z because there is no reasons to square it, it cannot be positive, and there has to be a z in the answer.
Answer:
C. 400 miles
Step-by-step explanation:
In each hour, it travels 80 miles. (That is the meaning of "80 miles per hour.") So you can add up the distances over a period of 5 hours:
80 miles + 80 miles + 80 miles + 80 miles + 80 miles
After the first sum (80+80=160), you can see what the correct answer will be. Continuing, you find the sum to be ...
= 400 miles
___
Multiplication was invented to make repeated addition easier.
5 × 80 miles = 400 miles
_____
Strictly speaking, you are multiplying numbers with units here:
(5 h) × (80 mi/h) = 400 mi·h/h = 400 mi . . . . . . the units h/h cancel
