Answer:
33 minutes
Explanation:
The principle of progression suggests that overload must be increased using frequency, intensity, time and type, when your present routine of exercise is no more felt by your body. Hence since Sally is jogging three times per week for 30 minutes, she could either increase it to jogging same 3 times a week, but instead increase her time by a factor of three to 33 minutes.
Answer:
Minimum cost and vitamins are achieved at $0.24.
Explanation:
Two equations
8x + 6y = 48
x + 2y = 12
Cost function
C = 0.05x + 0.03y
Minimum cost is $0.24.
which is achieved at 0 ounces of oat and 8 ounces of rice
Vitamin A
8x + 6y - 48
Vitamin B
x + 2y = 12
Put these equations on a graph
C= 0.05 {0} + 0.03 {8}
C= $0.24
Thus the minimum cost and vitamins are achieved at $0.24.
