Help please time limit...Amanda is choosing between two exercise routines.
1 answer:
Amanda must spend more than 8 minutes on Routine #1 to burn more calories than Routine #2.
Step-by-step explanation:
Routine # 1;
Calories burned in running = 15.5 per minute
Let,
t be the minutes spent running.
T = total calories burned
T = 15.5t
Routine # 2;
Calories burned while walking = 22 calories
Calories burned while running = 12.75 per minute
T = 12.75t + 22
For burning more calories in Routine 1;
Routine 1 > Routine 2
Dividing both sides by 2.75
Amanda must spend more than 8 minutes on Routine #1 to burn more calories than Routine #2.

Answer:
The volunteers donated millimeters of blood.
Step-by-step explanation:
Given:
Total Number of Volunteers = 32
number of Volunteers failed to donate = n
Amount of blood donated by each volunteer = 470 mm
We need to find the Total amount of blood donated by the Volunteers.
Solution:
First we will find the number of volunteers donated blood.
the number of volunteers donated blood is equal to Total Number of Volunteers minus number of Volunteers failed to donate.
framing in equation form we get;
the number of volunteers donated blood =
Now we will find Total amount of blood donated by the Volunteers.
Total amount of blood donated by the Volunteers is equal to Amount of blood donated by each volunteer multiplied by the number of volunteers donated blood.
framing in equation form we get;
Total amount of blood donated by the Volunteers =
Hence The volunteers donated millimeters of blood.
