As they are similar corresponding sides are in the same ratio, so

18/15 = x / 4

x = 4*18 / 15
x = 4.8 answer

A sphere has a radius of 6 inches. What is the volume of the sphere in terms of π?
natka813 [3]

The volume of sphere in terms of \pi is 288\pi cubic inches, if the sphere has a radius of 6 inches.

Step-by-step explanation:

The given is,

                       A sphere has a radius of 6 inches

Step:1

                      Formula for volume of sphere is,

                                               Volume, V =\frac{4}{3}\pi  r^{3}...........................(1)

                      where, r - radius of sphere

                      From given,

                                  r -  6 inches

                     Equation (1) becomes,

                                                               = \frac{4}{3}\pi  (6)^{3}

                                                               = \frac{4}{3} \pi(216)            ( ∵ 6^{3} = 6×6×6 =216 )

                                                               =  (1.3333)\pi (216)

        ( The volume of the sphere in terms of π, So keep the value of \pi )

                                                               = 288\pi

                                                               = 288\pi Cubic inches

                           Volume of sphere, V = 288\pi Cubic inches

Result:

              The volume of sphere in terms of \pi is 288\pi cubic inches, if the sphere has a radius of 6 inches.

The equation of three other functions are given which function or functions have a slope equal to the slope of Function 1
ratelena [41]

Answer:

See Explanation

Step-by-step explanation:

Required

Function(s) with the same slope as function 1

The question is incomplete as function 1 and the three additional functions are not given.

However, I will provide a general explanation.

A slope is represented as:

y = mx + b

Where

m \to slope

So, considering the following equations

y = 2x + 3

y = \frac{3x}{2} + 9

y = 2x - 5

y = -2x + 3

The following equations have the same slope

y = 2x + 3 and y = 2x - 5

Because: y = mx + b implies that:

m = 2 for y = 2x + 3 and y = 2x - 5

What is the solution to this system of equations?
Semenov [28]

Answer:

D

Step-by-step explanation:

y=2x²+2x+1.... i

y=2x+3......... ii

Equating i and ii,

2x²+2x+1=2x+3

2x²+1-3=0

2x²-2=0

x²-1=0

x=1 or -1.

From ii, if x=1,y=5

If x=-1, y=1.

The points are (-1,1) and (1,5)

The volume of a rectangular box is 330 cubic inches. The length on one side of the top is 11 inches, and the height of the box i
Fiesta28 [93]

Answer: 110 square inches.

Step-by-step explanation:

The volume of a rectangular box would be:

V=length*width*height

In this case, we know the volume, the length and the height, and we don't know the width, so we're going to isolate it:

width=\frac{V}{length*height}

Substituting the data:

width=\frac{330}{11*3} =10in

This width is also the width of the top of the box, so the area of the top would be:

A=length*width\\A=11*10\\A=110in^{2}
