Answer:

Twice as much water will fill twice as many containers. Thus, 1 cup of water will fill \frac43 of a container.

Step-by-step explanation:

<12 and <11 are not linear pairs to <14

Explanation:

A linear pair is created when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Answer:

424.1175

Step-by-step explanation:

Volume of the total pool = π[tex]r^{2}[/tex]h

                                        = π x [tex]6^{2}[/tex] x 5

                                        = 565.49

needed to fill a 3/4 of the pool = [tex]\frac{3}{4}[/tex] x 565.49

                                                   = 424.1175

Considering the volume of a cylinder, the amount of water needed to fill a 3/4 of the pool is 135π ft³.

Volume is a measure of the space occupied by an object in three-dimensional space, using cubic units to measure it. The volume formula depends on the shape of the figure and its different dimensions.

Volume can be considered as the capacity of a container to hold a quantity of fluid (gas or liquid).

In the case of a cylinder, it is characterized by having two circular bases and a surface that joins the two bases. So the volume of a cylinder is π×r²×h.

In first place, you must know that the length of the radius is half the length of the diameter.

On the other side, it is needed to fill a 3/4 of the pool.

Then, considering the definition of volume and the expression of volume of a cylinder, the amount of water needed is calculated as:

amount of water=(3/4)×π×(12 ft ÷2)²× 5 ft

Solving:

amount of water=(3/4)×π×(6 ft)²× 5 ft

amount of water= 135π ft³

Finally, the amount of water needed to fill a 3/4 of the pool is 135π ft³.

Answer:

-36

Step-by-step explanation:

y=-36x-25

y=mx+b

m=-36

m=slope

Hello there! :)

y+3=-4(9x+7)

This equation is written in point-slope form (y-y1=m(x-x1)

Where m is the slope.

In this case, it's -4.

Answer:

rational

Step-by-step explanation:

A rational number can be expressed in the form

[tex]\frac{a}{b}[/tex] where a and b are integers.

[tex]\sqrt{36}[/tex] = ± 6, and

± 6 × [tex]\frac{2}{3}[/tex] = ± 4 , that is [tex]\frac{4}{1}[/tex] or - [tex]\frac{4}{1}[/tex] ← rational numbers

Answer: 60 degrees / 360 = 1/6

the arc is (1/6)(2pi)radians

Answer :

A. infinite

4/5 (20x + 5) = 16x - 2

16x + 4 = 16x - 2

16x - 16x = -2 - 4

0x = -6

x = -6/0

x = infinite

The equation has zero solution.

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.

Given here,  the expression as 4/5 (20x+5)=16x-2

                                                   80x+20 = 80x-10

                                                        20 =- 10  which is not possible

Hence, the equation has no solution and thus D is the correct option.

Answer: x = 27

Step-by-step explanation:

The angles (4x + 7) and 5(x - 4) are opposite angles formed by intersecting lines.

When intersecting lines form two sets of opposing angles, both pairs are equal in angle measure.

As such, the angles (4x + 7) and 5(x - 4) are equal. Knowing this, you can solve for x by setting the angles equal to each other in an equation:

[tex](4x + 7) = 5(x - 4)\\\\4x + 7 = 5x - 20\\\\27 = x[/tex]

X = 27.

(0,0) is on the same line as (6,4) and (3,2) so it doesn't even form a triangle, much less a right triangle.

(3,6) forms a scalene isosceles triangle, but not a right triangle  It's a 4-sqr13-sqr13 triangle
