First you need to look at what you have, in this problem you have 3 variables, h, g, and t. H is given to you, it is 6, t is what you are solving for, and g is 32ft/sec. With this we can plug our numbers into the equation.
6=-1/2(32)(t^2)+6
6=-16(t^2) +6
16= t^2
4=t
The time of the fall would be 4 seconds.
Okay, So We Need To Find 15% Of 80.
Set Them Up As A Fraction Equation.
X 15
--- = ---
80 100
Multiply Means And Extremes.
100X = 80*15
Simplify.
80 * 15 = 1200
So;
100x = 1200
Now, Divide:
100x/100 = 1x = x
X = 1200/100
1200/ 100 = 12.
So:
X = 12.
This Means, 15% Of 80 Is 12.
The answer is square inches
Answer: $18.52
Step-by-step explanation: First you multiply the grocery store purchases by 3%, then you multiply the other purchases by 1.5%. Then you add together to get your total cash back
$326.79x.03=$9.80
$581.34x.015=$8.72
$9.80+$8.72=$18.52
