Answer:

volume of cylinder =π r^2 h

Step-by-step explanation:

Volume is proportional to square of radius and linearly proportional to height of cylinder. if h kept constant radius is doubled volume increases by 2^2 ie it becomes 4 fold. If radius trebled volume will be 9 times the original keeping h constant

if you keep h constant increase radius 4 times volume increases by 4 times only

v/πr^2h is constant =π like circumference/diameter =π

Answer:

y = 6.25x + 8.75

Step-by-step explanation:

Kayla works at a coffee shop. Yesterday she earned $6.25 an hour plus $8.75 in tips.

Let x represent the number of hours worked and y represent the total amount earned.

We have,

Net tip = $8.75

She earned $6.25 per hour.

Initial value = 8.75

So,

Total amount earned, y = 6.25x + 8.75

Hence, this is the required solution.

Answer:

70

Step-by-step explanation:

add 90 to 130 which equals 220 then subtract 220 from 360 which gives you 140 and after divide 140 by 2 and you get 70

130+90=220

360-220=140

Answer:The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

Answer:

Storm is 35, Cyclops is 33 and Wolverine is 38.

Step-by-step explanation:

W, S and C represent the agres of Wolverine, Storm and Cyclops.

W = S + 3

C = S - 2

W + S + C = 106

Making the indicated substitutions, we get:

(S + 3) + S + (S - 2) = 106

Combining like terms:

3S + 1 = 106, and 3S = 105.  Thus,

S = 35, C = 35 - 2, and W = S + 3.

Storm is 35, Cyclops is 33 and Wolverine is 38.

Answer:

30 Kilometers

Step-by-step explanation:

The longest measure from the given measures is 30 kilometers.

A no. of measurement values are given in the question.

We have to find out which is the longest from them.

What is the meaning of unit conversion ?

A unit conversion is done to express the same property as a different unit of measurement.

As per the question ;

Some measures i.e., 90 centimeters, 40 meters, 30 kilometers, 10 meters, 40 millimeters are given.

Let's check which is the longest by converting them all in same units say centimeters.

So ;

a) 90 centimeters

= 90 centimeters

b) 40 meters

= 40 × 100 centimeters

= 4000 centimeters

c) 30 kilometers

= 30 × 1000 meters

= 30000 × 100 centimeters

= 3000000 centimeters

d) 10 meters

= 10 × 100

= 1000 centimeters

e) 40 millimeters

=  40 / 10 centimeters

= 4 centimeters

So ; the longest is 30 kilometers.

Thus , the longest measure from the given measures is 30 kilometers.

Answer: 129 Feet

Step-by-step explanation:

You can make an equation where Height=h, and Base=b. So going backwards with the first question, the base will equal 4 times the height: b=4h, and 11 less. b=4h-11. The the other equation will be just that the base plus the height is 49. b+h=49. Then you put that into y=mx+b form. The first equation already is, and the second equation would be b=49-h. So, since the equations equal the same things, you throw away the b. Then you make a new equation by having 4h-11 equal 49-h. Since this is true seeing as they are the same triangle. Then you just use propreties of equality for the equation. You end up with 5h=60. The. You divide 60 by 5 to make 5h just equal h. So you get h=6. Then, like the qeuation said, the base (unknown) plus the height (6) is 49. So to get from 6 to 49, the answer is 43. The formula for that area of a triangle is (base x height) /2 = area. So 43 times 6 is 258. Then divided by 2 is 129. So the area of the triangle is 129.

The area of the triangle is 222 square feet.

The formula for calculating the area of the triangle is expressed as:

A = 0.5bh

The base of a triangle is eleven feet less than  four times its height,

b = 4h - 11

Also, if the sum of the lengths of  the base and height of the triangle is 49 is expressed as:

b + h = 49

4h-11+h = 49

5h = 49 + 11

5h = 60

h = 12

Since 4h = b + 11

4(12) = b + 11

b = 48 - 11

b = 37

A = 0.5(12)(37)

A = 222ft^2

Hence the area of the triangle is 222 square feet.

A = 180 units²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

The triangle on the left is right with h = 24 (7- 24- 25 triangle )

Here h = 24, b₁ = 4 and b₂ = 7 + 4 = 11 , then

A = [tex]\frac{1}{2}[/tex] × 24 × (4 + 11) = 12 × 15 = 180 units²

Answer:

B no

Step-by-step explanation:

If (n - 10) is a factor then if the polynomial equals zero when evaluated for 10 it is a factor

10³ - 17(10)² + 61(10) + 92

= 1000 - 1700 + 610 + 92

= 2 ≠ 0

Then ( n - 10) is not a factor of the polynomial

Slope intercept form is y=mx+b. So let's use the given equation and turn it into this form.

[tex]3x-5y=-30[/tex]

Move the -3x to the right side

Answer:

294 square meters

Step-by-step explanation:

The surface area of a certain pyramid is 54 square meters. Its volume is 648 cubic meters. If a similar pyramid has a volume of 8232 cubic meters, what is its surface area?

We solve the above question using Proportion

The surface area of a certain pyramid

= 54 square meters.

Volume of certain pyramid =

648 cubic meters.

Surface area of similar pyramid = x

Volume of similar pyramid = 8232 cubic meters.

Hence,

Surface area : Volume

= Surface area/ Volume

= 54 m²/648 m³ = x/8232 m³

Cross Multiply

54 × 8232 = 648 × x

x = 54 × 8232/648

x = 294 square meters

Answer:

The width of the box is 5 in

Step-by-step explanation:

the formula for the volume of a rectangular box of length L, width W and height H is V = L*W*H.  Here we know V, L and H and want to find W.  Solving this equation for W, we get W = V/(LH).

With V = 180 in^3, H = 4 in and L = 9 in, W comes out to be

            180 in^3

  W = ------------------ = 5 in

            (4 in)(9 in)

The width of the box is 5 in

Answer:

We have

[tex] \begin{cases} \sf Volume = \frak{480 \: cu \: cm}\\ \sf Length = \frak{4 \: in} \\ \sf Height = \frak{4 \: in}\end{cases}[/tex]

Volume = lbh

180 = 9 × b × 4

180 = 36b

180/36 = b

5 = b

Therefore,
