Answer:

UV corresponds to RS.

\angle R corresponds to \angle U

Step-by-step explanation:

Given

\triangle SRQ and \triangle VUT

Transformation: Rigid

Required

Determine the true options

When a rigid transformation occurs from SRQ to VUT, the following are the corresponding sides:

SR to VU, SQ to VT, RQ to UT

And the corresponding angles are:

<S to <V, <R to <U and <Q to <T

From the corresponding sides above, we have:

SR to VU

Rewrite:

RS to UV

Hence: (c) is correct

From the corresponding angles above, we have:

\angle R to \angle U

Hence:

(b) is correct

This one is hard! try your best please.

Answer:

1. 301.6 in^{3}

2. 576 in^{3}

3. 274.41 in^{3}

Step-by-step explanation:

We know that the diameter of one of the spheres must be 4 in, because the length of the box is 12 in and there are 3 spheres along each side, and \frac{12}{3} =4. That means that the radius of a sphere is 2 in. Put 2 into the formula for the volume of a sphere, and then multiply your solution by 9, to get the total volume.

Then, you can find the volume of the box, because you know its dimentions are 12x12x4.

Subtract your answer for part 1 from your answer for part 2, and you have the solution to part 3. Hope this helps!! :-)

4x + 160y = 120
and
1x + 240y = 80

that will be be the equations. if we multiply the bottom equation by 4 we get:
4x + 960y = 320

now subtract one equation from another:
4x + 160y = 120
-(4x + 960y = 320)

and get:
-800y = -200
y = $0.25

now plug this into one equation
x +240(.25) = 80
x + 60 = 80
x = $20

so $20 per day and $0.25 per mile
