Find the height of a cone with a diameter of 12 m whose volume is 565 m3

Use 3.14 for n and round your answer to the nearest meter.

A. 15 m
B. 47 m
C. 5 m
D. 8 m

Answer:

15°

Step-by-step explanation:

Hi there bud,

A right angle is 90° as you might know. So with the given information we have the angle divided into 2 parts.

1st part value : 30°

2nd part value : 4x

so we have to find the value of 4x

=== 30 + 4x = 90

moving 30 to the rhs we get

4x=60

x==60/4

x = 15°

Please mark me as brainliest if you found this helpful. Good day ahead.

i took the test and got 100%

Monica originally had $1.50

Data;

To solve this, we have to write the word problem in an equation which we can solve.

Assuming she had x amount of money and she gave half to her brother, we can write an equation for that

[tex]x - \frac{x}{2} = x- 0.5x[/tex]

But she also lost 25 cents and she have 50 cents left, let's put this in an equation.

[tex]x-0.5x-0.25 = 0.50[/tex]

let's collect like terms and solve for x

[tex]x-0.5x-0.25=0.50\\0.5x=0.5+0.25\\0.5x= 0.75\\\frac{0.5x}{0.5} =\frac{0.75}{0.5}\\ x = 1.5[/tex]

From the calculations above, Monica originally had $1.50

Answer:

There are 12 red marbles

Answer:

11, 13

Step-by-step explanation:

Let one of the odd positive integer be x , then the other odd positive integer is x+2.

Their sum of squares:

[tex]x^{2} +(x+2)^{2}[/tex]

[tex]x^{2} +(x+2)(x+2)[/tex]

[tex]x^{2} +x^{2} +4x+4[/tex]

[tex]2x^{2} +4x+4[/tex]

Given that their sum of squares = 290

[tex]2x^{2} +4x+4 =290[/tex]

[tex]2x^{2} +4x = 286[/tex]

[tex]2x^{2} +4x -286 = 0[/tex]

[tex]x^{2} +2x -143 =0[/tex]

[tex]x^{2}+13x-11x-143 =0[/tex]

[tex]x(x+13)-11(x+13)=0[/tex]

[tex](x+13)(x-11)=0[/tex]

Therefore x = 11, x=-13

We take positive value of x:

So, x =11 and (x+2)= 11+2=13

Therefore , the odd positive integers are 11 and 13

The arrangement of the blocks is an illustration of permutation and combination

The number of possible arrangement is 27720 ways

The given parameters are:

n = 12

Black = 6

Red = 4

White = 1

Blue = 1

The number of possible arrangement is then calculated as:

[tex]Ways = \frac{12!}{6!4!1!1!}[/tex]

Evaluate the factorials

[tex]Ways = 27720[/tex]

Hence, the number of possible arrangement is 27720 ways

Answer:

if i read the question correctly the hairdresser cuts off 4 inches

Step-by-step explanation:

32 inches is the total length of her hair

so 4 inches off the total length means 32 - 4 which is 28 inches

so the hairdresser cuts off 4 inches and now she has 28 inches of hair left

The barber cut 4 inches of hair out of 32 inches of hair.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
Abigail has lovely, lustrous black hair that is 32 inches long. She asks the hairdresser to cut off 4 of the total length of her hair.
So barber cut the 4-inch out of 32 inch

Thus, the barber cut 4 inches of hair out of the 32 inches of hair.

Answer:

Step-by-step explanation:

Answer: Check out the graph below

The graph is a straight line through the points (0,6) and (1,8)

====================================

Explanation:

Plug in x = 0 to find that...

y = 2x+6

y = 2(0)+6

y = 0 + 6

y = 6

The point (0,6) is on the line

---------

Repeat for x = 1

y = 2x+6

y = 2(1)+6

y = 2 + 6

y = 8

The point (1,8) is also on the line

---------

Now plot the two points together on the same xy grid.

Draw a straight line through the two points. Stretch the line as far as you can in either direction. See below. I used GeoGebra to make the graph. It's a free graphing app.

Desmos is another useful free graphing tool. There are many options if you don't have a graphing calculator.

The volume of the oil is 18.0864 that is filled at a rate of $22 then the cost to fill the drum of oil is $397.9.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.

Given

A drum of oil has a height of 4 feet and a radius of 1.2 feet.

The oil costs $22 per cubic foot.

We know the volume of the cylinder

[tex]\rm Volume = \pi r^2h\\\\Volume = \pi *1.2^2 * 4\\\\Volume = 3.14 *1.44*4\\\\Volume = 18.0864[/tex]

The cost to fill the drum of oil will be

cost to fill the drum of oil = 22 x 18.0864

cost to fill the drum of oil = 397.9

Thus, The cost to fill the drum of oil is $397.9.
