Calculate the volume of the composite solid.
1 answer:
Answer:
B.) 191.1 cubic cm.
Step-by-step explanation:
First find the area of the rectangular prism. Because the formula is l * w * h, this becomes = 149.1.
For the volume of a pyramid, the equation is . We already know the height, and because it's sitting on top of the rectangular prism, the base should have the same area. In other words, if the prism has a base of 7*6, then the pyramid can be found through
. 7 Multiplied by 6 is 42, and since it's multiplied but also divided by 3, they cancel out, leaving only 42.
The sum of both of these shapes is 191.1 cm³.

The values are a = 7, b = -9, c = -18.
<u>Step-by-step explanation:</u>
The given quadratic equation is
The general form of the quadratic equation is
where,
- a is the coefficient of x².
- b is the coefficient of x.
- c is the constant term.
Now, you have to modify the given quadratic equation similar to the general form of quadratic equation.
So, bring the constant term 18 to the left side of the equation for equating it to zero.
⇒
Compare the above equation with general form
⇒ a = 7
⇒ b = -9
⇒ c = -18
Therefore, the values of a, b, and c are 7, -9 and -18.
