Answer:

Step-by-step explanation:

Volume = pi * r^2 * h = $\pi$ * 9^2 * 5 = 405 $\pi$

Surface area = 2 $\pi$ * h * r + 2 $\pi$ r^2 = 90 $\pi$ + 162 $\pi$ = 252 $\pi$

the amount of water in a bathtube as it drains can be modeled by this equation with y representing the number of gallons of wate

koban [17]

Since $y$ is representing the number of gallons of water in the tub, we need to replace $y$ with the number of gallons remaining in the tube to find the time. Fortunately, the problem is telling us just that: 17.8 gallons. The only thing left is replacing that value in the equation, and solve for $x$ to find the time:
$17.8=-7.3x+39.7$
$7.3x=21.9$
$x= \frac{21.9}{7.3}$
$x=3$

We can conclude that after 3 minutes <span>the tub will have 17.8 gallons of water remaining.</span>

The area of a triangle piece of stained glass is 50 centimeters if the height of the triangle is four times the base, how long a

gavmur [86]

Answer:

Base = 5 cm

Height = 20 cm

Step-by-step explanation:

Points to remember

Area of triangle = bh/2

Where b - base of triangle

h - Height of triangle

<u>To find the Height and Base of given triangle</u>

It is given that,area of a triangle piece of stained glass is 50 centimeters

the height of the triangle is four times the base

h = 4b

Area = bh/2

50 = (b * 4b)/2

100 = 4b²

b² = 100/4 = 25

b =√25 = ±5

b = 5 then h = 4b = 4 * 5 = 20

Base = 5 cm and Height = 20 cm
