Answer:
5 batches
Step-by-step explanation:
Each batch takes 2 1/5 = 11/5 cups of flour. That is 1/5 of 11 cups of flour.
If Mike has 11 cups of flour and uses 1/5 of that amount for each batch, he can make 5 batches.

the degree of 8^8t
16777216t : the degree of the mnonmial is 1, because the degree of the variable is 1
Answer:
21 mph
Step-by-step explanation:
The relationship between time, speed, and distance is ...
time = distance/speed
The speed downstream is b+7 if the boat's speed is b. The speed upstream is b-7, and the times in each direction are equal. This means ...
20/(b+7) = 10/(b-7) . . . . . . time in each direction are the same
20(b-7) = 10(b+7) . . . . . . . cross multiply
(20-10)b = 7(10+20) . . . . . add 7(20)-10b
b = 7(20 +10)/(20 -10) = 21 . . . . mph
The speed of the boat in still water is 21 mph.
Answer:
X = 10
Y = 48/5
Step-by-step explanation:
Your welcome.
Answer: The function that modes this situation would be: y = 475(1 + .0125)^x.
This is an example of an exponential equation. These equations are always in the form y = ab^x.
The a value is the starting value. The b value is the interest rate. The x value is the number of years.
The only thing to be careful about is the rate. We are adding 1.25% or 0.125. Make sure that you are adding 1 whole to the 1.25% and don't just use 0.125.
