What is the height of a rectangle when I base is 8 ft and the area is 30 ft

To do this you have to fill in the equation $base*height=area$ , but you don't know the height, so we'll use $h$ for height. Plugging in the numbers you gave me, the equation is: $8*h=30$ . To solve this, we need to find $h$ . To find height you do $\frac{area}{base}$ . Doing this, we get $h$ = 3.75 ft.

Hope this helped!

Two friends purchase 2 pounds of pinto beans, 1 pounds of brussels sprouts, and 2 pounds of olives. If the friends split the tot

fiasKO [112]

The cost per friend is $6.84.

<h3>What is the cost per friend?</h3>

The first step is to determine the total cost of the vegetables the two friends bought.

Total cost of the vegetables = ( 1 x $2.82) + 4.19 X 2 + (1.24 x 2) = $13.60

In order to determine the cost per friend, divide the total cost of the vegetables by the number of friends that purchased the items.

$13.6 / 2 = $6.84

PlzplPzlpzlzpzl .......i beg u do this easy question for me ....

Answer: $-p^2-(q+r)^2$

Work Shown:

I'm assuming your teacher wants you to factor as much as possible.

$-p^2-q^2-r^2-2qr\\\\-p^2-q^2-2qr-r^2\\\\-p^2-(q^2+2qr+r^2)\\\\-p^2-(q+r)^2\\\\$

In the last step, I used the rule that $(a+b)^2 = a^2+2ab+b^2$

We cannot factor any further. If the first term was $p^2$ instead of $-p^2$ , then we could use the difference of squares factoring rule.

Calculate the volume of the cylinder, where a = 18 and b = 11. Use 3.14 for pi and round your answer to the nearest tenth.

cupoosta [38]

Answer:

Volume of cylinder $=2797.7$

Step-by-step explanation:

Let $a$ be diameter and $b$ the height of the cylinder

$Then\ radius(r)=\frac{diamater\ (a)}{2}\\\\r=\frac{18}{2}\\\\r=9$

Volume of cylinder $=\pi\times(radius)^2\times(height)$

$=\pi\times(9)^2\times11\ \ \ \ \ \ (\pi=3.14)\\\\=3.14\times9\times9\times11\\\\=2797.74\\\\\approx2797.7$
