Answer:

The volume of the cylinder is about 1256.6 cubic meters.

Step-by-step explanation:

The volume of a cylinder is given by the formula:

$\displaystyle V=\pi r^2h$

Where r is the radius and h is the height.

Our radius is 10 meters and our height is four meters. Substitute:

$\displaystyle V=\pi(10)^2(4)$

Evaluate:

$V=400\pi \text{ m}^3\approx 1256.6\text{ m}^3$

Thus, the volume of the cylinder is about 1256.6 cubic meters.

A=5x+20 B=9x-92 Solve for x and then find the measure of A

Leviafan [203]

Because of the transversal and the parallel lines, we know that A+B=180°.

So:
5x + 20 + 9x - 92 = 180
14x - 72 = 180
14x = 180 + 72
14x = 252
x = 252/14
x = 18

A = 5x + 20
A = 5*18 + 20
A = 90 + 20 = 110

(Let’s check:
B = 9*18 - 92
B = 162 - 92
B = 70
70 + 110 = 180)

Plz help me .....simplify the ratio of 0,0064kg to 32 grams

Degger [83]

Answer:

1/5

Step-by-step explanation:

1 kg = 1000 g so your ratio is ...

$\dfrac{0.0064\text{ kg}}{32\text{ g}}=\dfrac{0.0064\cdot1000\text{ g}}{32\text{ g}}=\dfrac{6.4}{32}=\boxed{\dfrac{1}{5}}$

On a rectangular soccer field, Sang is standing on the goal line 20 yards from the corner post. Jazmin is standing 99 yards from

nordsb [41]

Okay, so Sang is standing 20 yards away from one corner, and Jazmin is standing 99 yards away from the same corner. If this is a rectangle (I like visuals, so I'll use them to explain), then:

99ft
A ------------------------- B
   |    |
20 ft |    |
   |    |
C -------------------------- D

The question is asking you to solve for the diagonal line between points C and B. If you imagine a line there, you actually have the rectangle split into two triangles. So if you have triangle ABC, side CB would be the longest line, or the hypotenuse. That means you can use the Pythagorean Theorem to solve the problem.

A^2 + B^2 = C^2
99^2 + 20^2 = C^2
9,801 + 400 = C^2
10,201 = C^2

Now you solve for the square root of 10,201 to get C.

sqr (10,201) = C
C = 101 yards

Slope-Intercept Applications ( = mx +O)

Afina-wow [57]

The cost of downloading the app and downloading 30 songs is $40.7

Step-by-step explanation:

The equation can be written using slope-intercept form

Let x be the number of songs

Then

$1.29 per song will be written as

1.29x

for x number of songs

The initial charges are $2 so the equation will be:

$f(x) = 1.29x+2$

To find the cost of 30 songs, we have to put x= 30

So,

$= 1.29(30)+2\\=38.7+2\\=40.7$

Hence,

The cost of downloading the app and downloading 30 songs is $40.7
