Step-by-step explanation:

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.

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:

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°

Answer:

  see attachments

Step-by-step explanation:

The solutions to the two systems of inequalities are probably best represented on a graph. In each case, the boundary line of the solution area will be dashed, indicating the values on the line are not part of the solution. The doubly-shaded area is the solution space.

see the first attachment

x=-3 is a vertical line; 6x +4y < -8 has x-intercept -4/3 and y-intercept -2. The slope of the line is -3/2.

__

see the second attachment

y = 3 is a horizontal line; 2x -3y < -3 has x-intercept -3/2 and y-intercept 1. The slope of the line is 2/3.

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.

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]

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

We can measure the dimension of the triangle with the help of a ruler and protector.

In triangles, ΔABC and ΔGEF.

The side of AB is equal to EF, the side BC is equal to FG, and the side AC is equal to GE.

Since the (S, S, S) condition is fulfilled.

Step-by-step explanation:

Answer:

D. 60°

Step-by-step explanation:

The interior angles of all triangles add up to 180 degrees.

There are two y's on the triangle

And one of the degree lengths is 60°, so we do:

2y + 60 = 180

Subtract 60 from both sides

2y + 60 - 60 = 180 - 60

2y = 120

Divide 2 from both sides

2y/2 = 120/2

y = 60°

Also, In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

All three sides are equal

All the three interior angles are equal to 60 degrees

The interior angles of all triangles add up to 180 degrees.

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
