<h3>Answer:</h3>

The transformation is a rotation.

<h3>Step-by-step explanation:</h3>

The incorrect answers can be ruled out as follows:

  • dilation would change the size, but not the directions of the lines
  • reflection would change the DEF ordering from clockwise to counterclockwise
  • translation would move the figure, but not change the directions of the lines

The image is the same size as the original. Each of the sides of the triangle is moved through the same angle. The transformation is a rotataion.

The center of rotation can be found as the point of intersection of the perpendicular bisectors of DD', EE' and FF'

Vicky ran 5⁄14 of a mile and walked 1⁄7 of a mile. how much further did vicky run than walk?
raketka [301]
To solve, we need to subtract from these two fractions. In order to do this, we will change one of them to have the same denominator as the other.

We have 5/14 and 1/7
Let us change 1/7

Multiply 2/2 (a form of 1 so it does not change the value of the fraction)

2/2 • 1/7 = 2/14

Now subtract from 5/14
5/14 - 2/14 = 3/14

ANSWER: Vicky ran 3/14 of a mile more

In 20 minutes, John can wrap 10 small boxes and Hank can wrap 12 small boxes. So, Hank can wrap more small boxes in 20 minutes than John can.

Step-by-step explanation:

Given,

John wraps;

2 small boxes = 4 minutes

1 small box = \frac{4}{2} = 2\ minutes

In 20 minutes,

20 minutes = \frac{Total\ time}{Time per box} = \frac{20}{2}

20 minutes = 10 small boxes

Hank wraps;

3 small boxes = 5 minutes

1 small box =\frac{5}{3}\ minutes

In 20 minutes = \frac{Total\ time}{Time per box} = \frac{20}{5/3}

20\ minutes=\frac{20*3}{5}\\20\ minutes=\frac{60}{5}\\20\ minutes= 12\ small\ boxes\\

In 20 minutes, John can wrap 10 small boxes and Hank can wrap 12 small boxes. So, Hank can wrap more small boxes in 20 minutes than John can.

Two mechanics worked on a car. The first mechanic worked for 5
ArbitrLikvidat [17]

<u>Answer:</u>

$50 and $115

<u>Step-by-step explanation:</u>

We know that,

the sum of the two rates = $165 per hour

Let x and (165 - x) represent the $/hour of the 15hr and 5hr mechanics respectively.

Then combining their charges together to get:

(x*15)hour+(165-x)*5 hour=1325

Solving for x to get:

15x-5x+825=1325

10x=500

x=50

So the rate charged per hour by one mechanic is $50 and for the other mechanic = (165-50)= $115.
