Answer:
slope = -7/2
Step-by-step explanation:
To find the slope, we will solve the equation for y.
7x-2y=0.2
Subtract 7x from each side.
7x-7x-2y=-7x+0.2
-2y = -7x+0.2
Then we need to divide each side by -2
-2y/-2 = -7x/-2 + 0.2/-2
y = -7/2 x -0.1
This is in the form y= mx+b where m is the slope and b is the y intercept.
So the slope is -7/2 and the y intercept is -0.1
The number of bricks that they make will be 25 bricks.
Let the prism with a length of L, a width of W, anda height of H. Then the volume of the prism is given as
V = L x W x H
A company makes concrete bricks shaped like rectangular prisms. Each brick is 11 inches long, 8 inches wide, and 5 inches tall. Then the volume of each brick will be
V = 11 x 8 x 5
V = 440 cubic inches
If they have used 11,000 cubic inches of concrete, then the number of bricks that they make will be
⇒ 11,000 / 440
⇒ 25 bricks
The number of bricks that they make will be 25 bricks.
More about the volume of the rectangular prism link is given below.
