Answers

The pairs that are equivalent to each other are 40/1000 and 40%, 6/5 and 120%, 1/8 and 12.5% . They are the correct answers because if we divide for example 6/5 , we would get 1.2 and to turn a decimal into a percent we have to move the decimal point 2 times to the right meaning that the percentage would be 120% and you just do that for all!

Find the quotient. Express your answer as a simplified fraction. 3/10 divided by 3.8

Answers

Answer:

4/5



Step-by-step explanation:

3/10÷3/8

=(3×8)/(10×3)

=24/30

Simplifying 24/30, the answer is

=4/5

The value of the quotient of ''3/10 divided by 3.8'' as a simplified fraction would be 3/38.

Given that;

The expression is,

3/10 divided by 3.8

Now it can be divided as,

3/10 divided by 3.8

3/10 ÷ 3.8

3/10 × 1/3.8

3/38

Therefore, the value of the quotient as a simplified fraction would be 3/38.

What is the absolute value? What symbol represents absolute value?

Answers

Answer:

Absolute value is the distance the number away is from 0. In simpler terms, if you had a -8 the absolute value is 8. I attached a picture of the absolute value symbols. The absolute value of a normal positive 8 is still 8 though because it's the same distance on a number line.

The most common way to represent the absolute value of a number or expression is to surround it with the absolute value symbol: two vertical straight lines. |6| = 6 means “the absolute value of 6 is 6.” |–6| = 6 means “the absolute value of –6 is 6.” |–2 – x| means “the absolute value of the expression –2 minus x

Two cars are traveling down the highway at the same speed. If the first car increases its speed by 10 kilometers per hour, and the second car decreases its speed by 10 kilometers per hour, then the first car will travel the same distance in two hours that the second car travels in three hours. What is the original speed of the cars?

Answers

Answer:

50mph

Step-by-step explanation:

Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.

A = 50+10

b = 50-10

A = 60

B = 40

A2 = 120

B3 = 120

120 = 120

Answer

120km

Step-by-step explanation:

let s = the original speed

Write a distance equation; dist = time * speed

3(s-10) = 2(s+10)

3s - 30 = 2s + 20

3s - 2s = 20 + 30

s = 50 km/hr is the original speed

confirm this, find the distances

3(50-10) = 120 km

2(50+10) = 120 km

What is the distance between the points? Round to the nearest tenth if necessary.

Answer:

-1/2x-2

Step-by-step explanation:

Distribute the negative sign from the right side to make the equation positive

1/4x - 7 + (-1)(3/4x) + (-1)(-5)

(basically multiplying -1 to 3/4x and -5 to eliminate it)

1/4x - 7 + -3/4x+ 5

Make the equation similar

(1/4x + -3/4x) + (-7 + 5)

combine like terms

1/4x + -3/4x = -2/4x --> Simplifies to -1/2x

Do the other integers

-7 + 5 = -2

Put it together

-1/2x-2
