Answer:
The answer is 6.
Step-by-step explanation:
Given is that the total volume is 360 cubic inches
The height is fixed at 3 inches
So, total area will be = square inches.
Let's assume the minimum size in any dimension to be 3 inches.
Now we have to find possible combinations of numbers greater than 2 that will make 120. So, we have
3 x 40
4 x 30
5 x 24
6 x 20
8 x 15
10 x 12
These have the same answer in reverse order as well. So we will consider these.
Therefore, there are 6 different paving stones with different base.

Answer:
The point is (7,0).
Step-by-step explanation:
The equation of a linear function in point-slope form is as follows :
...(1)
Where
(x₁,y₁) are the coordinates of the point which the line passes through it and (x,y).
Harold correctly wrote the equation y= 3(x–7)
or we can write it as :
y-0=3(x-7) ...(2)
Comparing equations (1) and (2), we get :
x₁ = 7 and y₁ = 0
So, the point is (7,0).
The correct option is (c).
Answer:
see graph of y=3/4 x-4
Step-by-step explanation:
Assuming you mean
Below is a graph of that one. The slope is 3/4 and the interception with the y axis is at y=-4. The equation is in its normal form y=ax+b with a=3/4 (slope) and b=-4 (y intercept), so no conversion needed.
You have to be careful on how you write these equations down. It might very well be that you meant:
or
However, those are more complex so I'm hoping for the first one... ;-)
