60 pounds of concrete each bag make.

Step-by-step explanation:Consider the provided information.

Let the number of concrete bags are used is represented by y.

Part (A)

3.5 bags of concrete mix for a new set of stairs and 2.25 bags  of concrete mix for a garden wall.

This can be written as:

Timothy mixed  345 pounds of concrete in all.

Therefore,

Hence, the required model is

Part (B)  Solve for y. How many pounds of concrete does each bag make?

Consider the above equation.

Solve the equation for y as shown.

Add the like terms.

Divide both the sides by 5.75

Hence, 60 pounds of concrete each bag make.

What is the volume of the prism given below?
patriot [66]

Answer: the answer is c. 420

Step-by-step explanation:

this is because

V= L*W*H

SO

V= 12*14*5

But since there is a triangle as the base you divide by 2 or multiply by 1/2

1/2( 12*14*5)= to 420

so the answer is 420

What is (-1,2) and (1,-4) in slope-intercept form?
omeli [17]
You will need the point slope formula if you don't know it already which is x2-x1 over y2-y1. so in this case, it would be 1-(-1) over -4 -(2) which gives you 1 over 3 simplified and that is your slope. you are then going to substitute one of the point in the slope formula, y=mx+b. so let's say you go with the first point and substitute it, that will give you, 2=1/3(-1)+b and you would solve for b. after you figure out your equation, you multiply 1/3 by -1 to give you -1/3+b=2. Then you would add -1/3 to both sides to get b by itself. You would have b= 2+(-1/3). you with then calculate the difference to get b= 2 1/3 or b= 2.3.

In your own words, explain what it means to dilate a triangle.
mrs_skeptik [129]

Answer:

It means that you take a triangle and make another one but this time it is not the same size of the first one but the same shape. In other words make it bigger or smaller than the first one.
