What is 2 thirds plus 3 fourths

Answers

2/3 + 3/4. To solve this equation sir you must find a common denominator. The lowest common denominator is 12. It will equal 17/12 or 1 and 5/10.
In order to find this you need to find a common denominator. 2/3 and 3/4 common denominator would be 12 and so what you do to the bottom you must do to the top. 2x4 is 8 and 3x3 is 9. that would make 8/12 and 9/12. 8 plus nine is 17 and 12 stays there so the answer is 17/12 which equals 1 and 5/10.

Identify the asymptotes.
y=1/x-6

Answers

Horizontal asymptote
y=1x−6

limx→∞
=1/x−6

=(1/x) / [(x/x)−6/x]

 

=0 / 1

= 0

The function is also undefined at x=6. So there is a vertical asymptote at x=6.

The Hogwarts Express train has reduced its one-way fare from 360360 360 360 galleons to just 270270 270 270 galleons. What is the percentage decrease in the fare?

Answers

we are given

original fare =360

new fare =270

now, we can find decrease in fare

decrease in fare = original fare - new fare

so, we can plug value

decrease in fare = 360-270

decrease in fare =90

now, we can find percentage decrease in fare

=(90)/(360)* 100

=25%...........Answer

Answer: I will just start off saying I love how they made this question harry potter themed but anyways the answer is 25%

Answer:

A) 83 km/ hour

B) 2/7 penalties / game

C) $16 / CD

D) 9 donuts / box

Step-by-step explanation:

A)

For this question they are asking for the distance traveled in 1 hour.

Since 747km was travelled in 9 hours, we divide 747 by 9 to find the distance travelled in 1 hour

747 ÷ 9 = 83

The unit rate is 83 km/ hour

B)

You have to find the number of penalties per game

Like before divide 10 by 35:

10 ÷ 35 = 10/35 = 2/7

2/7 penalties / game

C)

Find the cost of 1 CD :

64 / 4 = 16

Write a compound inequality that represents the situation. On a road in the city of Rochester, the maximum speed is 50 miles per hour, and the minimum speed is 20 miles per hour.A. 20 > x > 50

B. 20 ≤ x ≤ 50

C. 20 ≥ x ≥ 50

D. 20 < x < 50

Answers

Answer:

B. 20 ≤ x ≤ 50

Step-by-step explanation:

If the maximum speed is 50 miles per hour, that means it cannot go above 50 miles per hour, it has to be 50 miles per hour or less, which is expressed like this

x\leq 50

Now, if the minimum speed is 20 miles per hour, that means the speed can only be 20 miles per hour or more, that's represented as

x\geq 20

If we unit both expression, we would have the following compound inequality

20\leq x\leq 50

This means that the speed has to be 20 miles per hour or more, but 50 miles per hour or less.

Therefore, the right answer is

The correct answer is b. Hope that helps!
