Answer:
The answer is <u>140 cubic in</u>
Step-by-step explanation:
The formula for the volume of a prism is V=Bh, where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm. The area A of a rectangle with length l and width w is A=lw. Hope this helped! :) (ps. I am sorry if it does not help.)
Answer:
The second choice is correct. (f(x) = 8.50x+7.50)
Angel had +7.50 dollars to start off with and then worked 5 hours to get 42.50 dollars. This means, she earns 8 dollars 50 cents per hour, meaning that 8.50x would represent the total amount of money that she would earn from her job.
Let me know if this helps!
Answer:
f(x) = x² +x -6
Step-by-step explanation:
The standard form will look like ...
f(x) = x² +bx +c
where b is the opposite of the sum of the roots, and c is their product.
f(x) = x² -(-3+2)x +(-3)(2)
f(x) = x² +x -6
_____
<em>Additional comment</em>
In general, "standard form" is ax²+bx+c. In this case, the coefficient 'a' can be 1 since neither of the roots is expressed as a fraction. The sum of roots is (-b/a) and the product of roots is (c/a).
In order to calculate the volume of a cylinder, we can use the following formula:

Where r is the base radius and h is the height.
If the circumference is 8, we have:

Now, calculating the volume, we have:

So the correct option is the second one.
