1 is the number which is the answer
The perimeter of a rectangle si length + length + width + width or 2l + 2w. Substitute your values in to get 2(70) + 2(65) → 140 + 130 → 270 feet
To find the acceleration of the bicycle rider, we are going to use the acceleration formula:
where
is the acceleration
is the initial speed
is the final speed
is the time
We know from our problem that increases his speed from 5 m/s to 15 m/s in 10 seconds, so his initial speed is 5 m/s and his final speed is 15 m/s; therefore,
,
, and
. Lets replace those values in our formula:
We can conclude that the acceleration of the bicycle rider 1 m/s^2
Answer:
$70
Step-by-step explanation:
break it down, 100% of 40 is 40, and 75% of 40 is 30, so add 40 and 30 to get 70
