Answer:
5 ft
Step-by-step explanation:
Since we have a rectangle, we know for sure that perimeter = double the width and double the height. Algebraically, that looks like:
P = 2W + 2H
Let's sub in the given values, P and W:
18 = 2(4) + 2H
Now, let's solve for the height, H:
18 = 8 + 2H
10 = 2H
10/2 = H
<u>5 = H</u>
I hope this helps!
Answer: 15 pounds per inches
Step-by-step explanation:
P1V1 = P2V2
12 ppi × 5L = P2 × 4L
P2 = 12 ppi × 5L / 4L
P2 = 12 ppi × 5 / 4 ( L in denominator is cancelled by L in numerator)
P2 = 3 ppi × 5 ( 12 is cancelled by 4 in denominator)
P2 = 15 ppi
Initial number of quarters; 6
x = number of days
Number of quarters added after x days: 2x
Total amount of quarters, y = 2x + 6
Note: the slope is 2 and the y-intercept is 6.
32 as well according to some rule in geometry
