Answer:
Step-by-step explanation:
Surface area formula= 6×side^2.
1. Side=4=>area=6×4^2=6*16=96 inches^2.
2.side=8=>area=6×8^2=6*64= 384 inches^2
3. 384+96=480 inches^2
Answer:
Input
Independent variable
Step-by-step explanation:
we know that
<u><em>Independent variables</em></u>, are the values that can be changed or controlled in a given model or equation
<u><em>Dependent variables</em></u>, are the values that result from the independent variables
we have the function

In this problem
The function d(t) represent the dependent variable or the output
The variable t represent the independent variable or input
Answer:
1 / 20
Step-by-step explanation:
Brian = 11.74 seconds
Luis = 11.69 seconds
Difference between their times :
11.74 - 11.69 = 0.05
Expressed as a fraction of a second :
0.05 / 1 = (0.05 * 100) / (1 * 100) = 5 /100 = 1/20
Answer:
126
Step-by-step explanation:
The number of numbers divisible by 9 is ...
j = floor(500/9) = 55
The number of numbers divisible by 7 is ...
k = floor(500/7) = 71
Then the total (j+k) is ...
j +k = 55 +71 = 126
