A gaming system is marked down from 290 to 188. What is the percentage of the discount?

1 answer:

5 0

Let P = percent of discount

(290-188)/290 = P/100

102/290 = P/100

290P = (102)(100)

290P = 10,200

Solve for P to find your answer.

what is the exact circumference of the base of a cone that has a volume of 1014 pi in^3 and a height of 18 in.

Evgen [1.6K]

$\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
V=1014\pi \\
h=18
\end{cases}\implies 1041\pi =\cfrac{\pi \cdot r^2\cdot 18}{3}
\\\\\\
1041\pi =6\pi r^2\implies \cfrac{1041\pi }{6\pi }=r^2\implies \cfrac{347}{2}=r^2\implies \boxed{\sqrt{\cfrac{347}{2}}=r}\\\\
-------------------------------\\\\
\textit{circumference of a }\stackrel{cone's}{circle}\\\\
C=2\pi r\qquad \qquad C=2\pi \left( \boxed{\sqrt{\cfrac{347}{2}}} \right)$

On an airplane there are two seats on the left side in each row and three seats on the right side there are 90 seats on the righ

Anuta_ua [19.1K]

The correct answer is 60 seats on the left side, but you might also want to know how I got that answer . . .

Let's say, n = number of rows

Since we know the airplane has an equal number of rows on the right side as it does on the left side, then we can mathematically show that:

number of sears on the right side = 3n = 90 seats
number of sears on the left side = 2n = ? seats

3n = 90

n = number of rows = 90/3 = 30 rows

Thus:

2n = 2(30) = 60 seats on the left side

as for how many seats all together, just add . . 90 + 60 = 150 seats total
