Answer:

Step-by-step explanation:

A.) according to the graph, Austin appears to be burning 10 calories per minute. If you look at a perfect point on the graph, which I chose (50,5) and you do x over y or calories per minute, you get a unit rate of 10 calories per minute.
b.) Since you have already found the unit rate in question a, your slope would be 10.
Answer:
7.87 years
Step-by-step explanation:
#First we determine the effective annual rate based on the 9% compounded semi annual;

#We then use this effective rate in the compound interest formula to solve for n. Given that the principal doubles after 2 yrs:

Hence, it takes 7.87 years for the principal amount to double.
Answer:
C) Jo's drink will have a stronger orange taste
Step-by-step explanation:
tropical punch calls for 2 liters of pineapple juice and 3 liters of orange juice.
total is 2+3 = 5 liters
pineapple = 2/5
orange = 3/5
Jo creates a drink by mixing 3 liters of pineapple juice with 4
total = 7
pineapple = 3/7
orange = 4/7
Get a common denominator to compare
5 and 7 = 35
tropical punch
pineapple = 2/5 *7/7 = 14/35
orange = 3/5*7/7 = 21/35
Jo
pineapple = 3/7*5/5 = 15/35
orange = 4/7*5/5 = 28/35
Jo will have both a stronger pineapple and orange taste than the tropical drink and the orange will be stronger than the pineapple in her drink
