Answer:
20 seconds
Step-by-step explanation:
The distance to cover between the lead skater and trailing skater is 40 meters
The lead skater's rate is 12 m/s
The trailing one's rate is 14 m/s
So, we can say:
second skater is accelerating, or covering up the distance, in 14 - 12 = 2 m/s
So, at a rate of 2 meters per second, how long would it take to cover 40 meters??
We use the distance formula, substitute the known and solve for unknown.
Distance Formula = D = RT
Where
D is distance
R is speed/rate
T is time
We know
r = 2 m/s
d = 40 m
t = ?
Now,
D = RT
40 = 2t
t = 40/2
t = 20 (seconds)
Hence,
it will take 20 seconds for the second skater to catch up (pass)
Rounding to the nearest ten square feet means finding the closest multiple of ten to a given area in square feet.
Rounding to the nearest ten square feet means finding the closest multiple of ten to a given area in square feet. This is done by looking at the tens digit of the number. If the tens digit is 5 or greater, you round up to the next multiple of ten. If the tens digit is less than 5, you round down to the previous multiple of ten. For example, if you have an area of 67 square feet, rounding to the nearest ten square feet would give you 70 square feet.

Answer is B. 289
First find the area of the rectangle by multiplying Base x height. 17 x 13 = 221
Now to find the area of the huge triangle, you have to do (Base x height) / 2. So your height would be 8. Now your base would be the same as the length of the rectangle which is 17. (17 x 8) / 2 = 68
221 + 68 = 289
