Answer:
The answer is 6.75 calories or 
Step-by-step explanation:
First, we need to find out how many calories per 1/3 minute.
4 1/2 divided by 2 = 2 1/4 or 2.25
2 1/4 or 2.25 x 3 =
or 6.75 calories

Answer:
perimeter of the fountain = 15π ft. or 47.1 ft. to the nearest 10th
Step-by-step explanation:
The semicircles have a circumference of 1/2πd = 1/2π(10) = 5π
Both semicircles together have a length of 5π + 5π = 10π
The radius of the 1/4 circle is 10, so the diameter is 20
The length of the 1/4 circle's arc is 1/4 times the circumference of its circle
So, the length of that arc is 1/4π(20) = 5π
Now the perimeter of the fountain is 10π + 5π = 15π
2 + d = 2 - 3(d- 5) - 2
First, cancel 2 on both sides. / Your problem should look like:
Second, expand. / Your problem should look like:
Third, simplify -3d + 15 - 2 to get -3d + 13. / Your problem should look like:
Fourth, add 3d to both sides. / Your problem should look like:
Fifth, add d + 3d to get 4d. / Your problem should look like:
Sixth, divide both sides by 4. / Your problem should look like:

Answer:
7.2
Step-by-step explanation:
The amplitude is half the difference between the maximum and the minimum.
A = (7.7 − (-6.7)) / 2
A = 7.2
