Farmer Fran is harvesting her crop of pomegranates. We don’t know when she started, but at 10:00 A.M., she had already harvested
1 answer:
Answer:
<em>r = 3.5 acre/hour</em>
Step-by-step explanation:
<u>Rate of Change</u>
Farmer Fran had harvested 2 acres of pomegranates at 10:00 A.M. At noon (12:00 P.M.) she had harvested 9 acres.
From both times, 2 hours had passed. During that time, she harvested 9-2=7 acres.
The rate of harvesting is:
Or, expressed in decimal:
r = 3.5 acre/hour

Step-by-step explanation:
Four times three cubed
Given the statement, times means multiplication.
four times three
4 x 3
It says three cubed, where cubed means raised to 3. So that means we right an exponent, and the exponent is 3.
4 x 3³
When we have an exponent, that tells you how many times you will multiply it by itself. So since the exponent is 3, we multiply 3 by itself 3 times.
3³ = 3 x 3 x 3
So 4 x 3³ = 4 x 3 x 3 x 3
Lastly, if we get the product your result will be 108.
4 x 3 x 3 x 3
=4 x 27
= 108
