Answer:
The distance is 29.3 feet
Step-by-step explanation:
Here, we want to find the distance from the diving board to the bottom of the pool
To get this, we will need to add the height of the diving board above the ground plus the distance of the bottom of the pool below the ground
Mathematically, we can have this as:
12.4 + 16.9
= 29.3 feet
X+8y=18
-5x+3y=-4
Multiply the first equation by 5
Add the two equations together
5x+40y=90
-5x+3y=-4
43y=86
Y=2
Plug y into one equation to find x
X+16=18
X=2
Answer:

Step-by-step explanation:
Given

Required
Solve for x
Subtract 5 from both sides


Divide through by 3


Answer:
336in^3
Step-by-step explanation:
The volume of a rectangulur prism can be found by multiplying the length of the box with its height and width.
Thus, we can find the volume using the solution below:
v=l*w*h
l = 12in
h = 7in
w = 4in
12*7*4 = 336in^3
