Step-by-step explanation:

Yes, repeating decimals can be made into fractions, and in fact are racial numbers.

Y=3x-2 that’s the answer
Answer: y=3x-2

So to find the y-intercept, you look to see where the point is located when it crosses the y-axis. In this case, it crosses at (0, -2).

To find the slope, you do rise/run. Pick one point to start with. Count upwards, then over. You could also use slope formula if you know two points on the graph: slope= (y2-y1) / (x2-x1)

Put the following fractions in order from least to greatest, 1/8 2/5, 3/5, 1/6 1/4, 2/3, 1/3

Answers

Answer:

Order from Least to Greatest

1/8 < 1/6 < 1/4 < 1/3 < 2/5 < 3/5 < 2/3

Step-by-step explanation:

A fraction is a way to describe a part of a whole. The given fractions can be arranged as shown below.

What is a Fraction?

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

In order to put the following fractions in order from least to greatest, we need to take the LCM of the fraction so that all the fractions have the same denominator.

1/8, 2/5, 3/5, 1/6, 1/4, 2/3, 1/3

Since the LCM of 3, 4, 5, 6, and 8 is 120. Therefore, the fractions can be written as,

1/8 = (1/8) × (15/15) = 15/120

2/5 = (2/5) × (24/24) = 48/120

3/5 = (3/5) × (24/24) = 72/120

1/4 = (1/4) × (30/30) = 30/120

2/3 = (2/3) × (40/40) = 80/120

1/3 = (1/3) × (40/40) = 40/120

Now, the fractions can be arranged as,

15/120 < 30/120 < 40/120 < 48/120 < 72/120 < 80/120

Rewriting the fraction in there original form,

1/8 < 1/4 < 1/3 < 2/5 < 3/5 < 2/3

Answer in at least 2 complete sentences.

Answers

For example let’s pick 6 and 12. To find the greatest common factor, you will break down the number into the numbers you can multiply to get 6 or 12 as much as you can until you reach a prime number.
Now to find the least common multiple, you can set two tables, one of the multiples of 6 and another of the multiples of 12 and see what numbers they have in common and select the smallest number of the multiples they have in common.

A rectangle has its diagonal length increased from 5 cm to 25 cm. The new rectangle is similar to the original one. The original perimeter was 14 cm. What is the measure of the new perimeter?

Answers

Answer:

The measure of the new perimeter is 70cm.

Step-by-step explanation:

I thought putting up a picture would be easier than explaining it all. The picture is how you would write out the problem.

The original rectangle's measures were 5cm and 14cm. The new rectangles measures are 25 cm and X (We don't know yet.) So write it out. 5cm is to 14cm as 25cm is to X.

5cm/14cm = 25cm/X

Cross multiply. (The arrows I drew. Multiply diagonally.)

You should get

350 = 5X

We need to get X by itself, so divide both sides by 5.

5X/5 leaves X left

350/5 leaves 70

70 = X

The answer is 70 maybe?
