Answer:
Step-by-step explanation:
Let x represent height of the prism.
We know that volume of rectangular is equal to product of its height, width and length.
, where w, h and l represents width, length and height respectively.
We have been given that the surface area of rectangular prism is equal to the volume of the prism. So we can set an equation as:
We are also told that the measurements of the rectangular prism is 9 inches long and 4 inches wide. Upon substituting these values in above equation, we will get:
Let us solve for x.
Therefore, the value of x is 7.2 inches.
Answer for Problem 2:
x=61 degrees
Step-by-step explanation:
I'm not completely sure of problem 1, but I know what problem 2 is.
Tip: triangles always add up to 180 degrees.
1. 16+42= 58
2. 180-58= 122
3. 122 divided by 2= 61 degrees
ANSWER: x=61 degrees.
Answer:
y = 4
Step-by-step explanation:
An exponential function in standard form is
y = a 
Use ordered pairs from the table to find a and b
Using (0, 4), then
4 = a 
( note that = 1 ), so
a = 4, then
y = 4
Using (1, 8)
8 = 4 
= 4b ( divide both sides by 4 )
b = 2
y = 4 ← represents the values in the table
Answer: 3
Step-by-step explanation:
Distribute the 5: 15x-5=40
Add 5 from both sides: 15x=45
Divide 15 by both sides: 3
