x^2-9x=10|+20.25\\
x^2-9x+20.25=30.25\\
(x-4.5)^2=30.25\\
x-4.5=5.5 \vee x-4.5=-5.5\\
x=10 \vee x=-1

How many revolutions must be made by a wheel of diameter 2.8m in order to cover a distance of 484km?
arlik [135]
<h2>Answer :</h2>

A wheel is a circle.

Given diameter of wheel = 2.8 m

Then radius of the wheel = 2.8/2 = 1.4 m

Now we know that , circumference of circle =2\pi r

<h3>Then, </h3>

Circumference of wheel = 2 × 22/7 × 1.4

Circumference of wheel = 8.8 m

<u>From the above we can conclude that ;</u>

1 revolution = 8.8 m

x revolution = 484 km = 484000 m

<h3>Thus, </h3>

x =  \frac{1}{8.8}  \times 484000 \\  \\ x = 55000

<h3>Therefore, total of 55,000 revolutions are made by the wheel.</h3>

What is the scale factor in the dilation?
Bumek [7]

The scale factor of the given dilation is 3.

Step-by-step explanation:

Step 1:

In order to determine the scale factor, we divide the measurement after scaling by the same measurement before scaling.

In the given graph, the preimage has a length of 3 units while the image has a length of 9 units.

Step 2:

So here the measurement after scaling is the length of the image which is 9 units and the measurement before scaling is the preimages length of 3 units.

The scale factor =\frac{9}{3} = 3.

So the scale factor is the third option 3.
