The formula to solve a cylinder is V=πr²h

So, round pi to 3.14

We must plug in for the radius (r) in this equation. To do this, we must half up the diameter, 5. 5/2 = 2.5

6 is height

V=3.14 * 2.5² * 6

V=117.81 we must round though to tenth, and that would be:

Answer V=117.8m³

If f(x) = <img src="https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D" id="TexFormula1" title="\frac{1}{9}" alt="\frac{1}{9}" align=
boyakko [2]

Answer:

Solution given:

f(x) = \frac{1}{9} x-2

let f(x)=y

y = \frac{1}{9} x-2

interchanging role of x and y

x= \frac{1}{9} y-2

x+2= \frac{1}{9} y

y=9(x+2)

y=9x+18

So

<u>F</u><u>-</u><u>¹</u><u>(</u><u>x</u><u>)</u><u>=</u><u>9</u><u>x</u><u>+</u><u>1</u><u>8</u>

<u>a</u><u>n</u><u>d</u>

<u>F</u><u>-</u><u>¹</u><u>(</u><u>-</u><u>1</u><u>)</u><u>=</u><u>9</u><u>*</u><u>-</u><u>1</u><u>+</u><u>1</u><u>8</u><u>=</u><u>-</u><u>9</u><u>+</u><u>1</u><u>8</u><u>=</u><u>9</u>

A conveyor belt carries supplies from the first floor to the second floor, which is 26 feet higher. The belt makes a 60° angle w
tamaranim1 [39]
<h3>Answer:</h3>

30 ft; 0.4 min

<h3>Step-by-step explanation:</h3>

The mnemonic SOH CAH TOA reminds you ...

... Sin = Opposite/Hypotenuse

Here, the angle of elevation is opposite the triangle side representing the distance between floors. The hypotenuse is the length of the conveyor belt. Rearranging the formula (by muliplying by Hypotenuse/Sin), we get ...

... Hypotenuse = Opposite/Sin

Filling in the values from this problem, we have ...

... length of conveyor = (26 ft)/sin(60°) ≈ 30 ft

The time it takes to travel that distance is given by ...

... time = distance/speed

... time = (30 ft)/(75 ft/min) = 2/5 min = 0.4 min

Kelli and Karl each have a job. Kelli earns $20 an hour. She also receives a $100 weekly bonus.
Firlakuza [10]
Answer:   When they work 10 hours each, they both make $300.

kelli    y = 20x + 100
karl    y = 25x + 50

substitution:

y = 20x + 100

25x + 50 = 20x + 100
-20x  -50    -20x   -50
--------------------------------
5x = <span>50 
</span>5       5

x = 10

(Then plug into any equation)
y = 25x + 50
y = 25(10)  + 50
y = 300

When they work 10 hours each, they both make $300.
