Answer: 22/2, 88/8, and 7062000/642000

Explanation: Notice that the ratio in this problem is written with a fraction bar, so we can find equal ratios in the same way that we find <em>equivalent fractions</em>. In other words, we can simply multiply both the numerator and denominator of 11/1 by the same number.

For example, we can multiply both the numerator and denominator of 11/1 by 2 to get the equal ratio 22/2.

We can also multiply both the numerator and denominator of 11/1 by 8 to get the equal ratio 88/8.

We could also multiply the numerator and denominator of 11/1 by 642,000 to get the equal ratio 7062000/642000.

So the ratio 11/1 is equal to  22/2, 88/8, and 7062000/642000.

avanturin [10]
<h2>Answer:</h2>

Option: D is the correct answer.

  D.    The slope of is 3, and passes through O.

<h2>Step-by-step explanation:</h2>

It is given that:

AB is dilated by a scale factor of 3 to form AB .

Also, the line AB pass through the origin.

So, if AB pass through (0,0) and some point (x,y) then the slope of line AB is:

Slope=\dfrac{y-0}{x-0}\\\\i.e.\\\\Slope=\dfrac{y}{x}=3

( Since, it is given the slope of AB is 3 )

Now , if AB is dilated to A'B' by a scale factor of 3 then

(0,0) → (0,0)

and

(x,y) → (3x,3y)

i.e. (0,0) and (3x,3y) will lie on A'B'.

Hence, the slope of line A'B' is given by:

Slope=\dfrac{3y-0}{3x-0}\\\\i.e.\\\\Slope=\dfrac{3y}{3x}\\\\i.e.\\\\Slope=\dfrac{y}{x}=3

Hence, both have the same slope.

                The answer is :  Option: D

g100num [7]

Answer:

1618 minutes

Step-by-step explanation:

Jerold reads at a rate of 3 pages in 2 minutes. He as a 2427 page novel to read and a 906 page mystery book to read. How long will it take him to read his novel?

From the question above, the number of pages for his novel = 2427 pages

His reading rate =

3 pages = 2 minutes

Hence:

3 pages = 2 minutes

2427 pages = x minutes

Cross Multiply

3 pages × x = 2427pages × 2 minutes

x = 2427pages × 2 minutes/3 pages

x = 1618 minutes

It would take him 1618 minutes to read his 2427 paged novel

OleMash [197]
The area of a rectangle is calculated my multiplying the length of the rectangle and the width of the rectangle. In this case, the length (the longer side) is 70 feet while the width (shorter side) is 30 feet. Hence the area is 2,100 ft2.

Lewis walked 9/10 of a mile. His friend walked 2/5 of the way with him. How many miles did Lewis's friend walk with him?
iVinArrow [24]

Answer:

Lewis's friend walked with him 9/25 miles

Step-by-step explanation:

Given that

Lewis walked 9/10 of a mile

And His friend accompanied him on 2/5 of the way.

This is a simple question of fraction multiplication

The fraction 2/5 has to multiplied with the miles walked by lewis

So

= \frac{2}{5} * \frac{9}{10}\\=\frac{9}{25}

Hence,

Lewis's friend walked with him 9/25 miles
