A rectangular prism has a volume of 1,200 cubic units. The area of the base is 80 square units.
What is the height of the prism?
(Show work)
Answers
Answer:
v= whl
1200= h X 80
1200/ 80 = h
so the height is 15 unit

v = h * l * w OR v = h * a
a = l * w
1,200 = h * 80
1200/80 = 15 units
9. The two figures below have a scale factor of 3 : 2. What is the value of x?
Answers
The value of x can be found by setting up a proportion based on the given scale factor of 3:2 is 16/3 units.
The breadth of the first parallelogram is 8 and the breadth of the second parallelogram is x.
Setting up the proportion, gives:
8/3 = x/2.
To solve for x, cross-multiply:
[tex]8 \times 2 = 3 \times x.[/tex]
Simplifying the equation, gives:
16 = 3x.
Next, divide both sides of the equation by 3 to isolate x:
x = 16/3.
Therefore, the value of x is 16/3.

Answers
HOPE IT HELPS
The graph of the equation is attached .
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The slope-intercept form of the line equation
y= mx + c
where m is the slope
b is the y-intercept
We are Given that the profit y (in dollars) for a business from selling x coats is represented by the equation
y=47x .
Now comparing with the slope-intercept form of the line equation;
m = 47
We know that the value of the y-intercept can be determined by setting x = 0
substitute x = 0 in the equation
y = 47(0)
y = 0
Thus, the y-intercept b = 1
Thus,
The slope m = 47
The y-intercept b = 1
The graph of the equation is also attached.
