What is the first 5 common multiples of 15 and 25

Answers

Answer 1

Answer: You can first find the missing factors of each number to find the lcm
So $15 = 5*3$ and $25 = 5*5$
In order to make them equal, Multiply 15 by 5 and 25 by 3 so that both of them are $5*3*5$ which equals 75.
After that you can just multiply each by 2, 3, 4, and 5 because all the other common multiples are multiples of 75. You get
150, 225, 300, 375, as well as 75
So:
75
150
225
300
375

Answer 2

Answer: 15 = 15,30,45,60,75,90,105,120,135,150,165,180,195,210,225,240, 255, 270,285,300,315,330,345,360,375
25 = 25,50,75,100,125,150,175,200,225,250,275,300,325,350,375

The first 5 common multiples of 15 and 25 are 75, 150, 225, 300, and 375.

Jane has a checkbook balance of $68.00. She then writes two checks, one for $5.00 and one for $62.50. She also deposits $75.00. She then uses her calculator to determine her new balance. Which of the following is the correct series of keys she should press? A.ON/C 6 8 + 7 5 = 5 = 6 2 . 5 0B. 6 8 + 75 – 5 – 6 2 . 5 0C. ON/C 6 8– 5 – 6 2 . 5 0 + 7 5 =D. 6 8 + 75 – 6 2 5 0 – 5 =

Answers

C because you want to do the steps in order. She started out with $68 then you subtract $5 and & 62.50 Then you add the deposit of $75.00

C because 5 and 62.50 is what she took at of her account. But she put in $75 somyou add that

What is the slope of a line that is perpendicular to the line y = 8x + 5?

Answers

perpendicular slopes are oposite inverse, ie. the slopes of perpendicular lines multiply to get -1
8 times -1/8=-8/8=-1

the slope is -1/8

just cancel 8 from both side and then you will have -1/8

A student spends no more than 2 hours on his math and English homework. If math takes about twice as long as long as english. How long will the student be able to finish hisEnglish homework?

Answers

E - English homework, M - Math homework;
M + E ≤ 2 hours
M = 2 E
2 E + E ≤ 2 hours
3 E ≤ 2 hours = 120 minutes
E ≤ 120 : 3
E ≤ 40 minutes
Answer:
The student will be able to finish his English homework in less or equal to 40 minutes.

Answer:

d) 2/3

Step-by-step explanation:

Step one: write your equations

"A student spends no more than 2 hours on his math and English homework." Our sign will be less than or equal to. Our operation will be addition since the question used "and" to connect math and English.

m=x; e=y

Equation a. x + y ≤ 2

Equation b. x = 2y (2y because math takes twice as long, therefore, we can multiply y by 2) Remember: x or y by itself has a coefficient of 1.

Step two: Substitute x into equation a.

x=2y so our new equation is: 2y + y ≤ 2

Step three: isolate y and solve

2y + y= 3y

3y ≤ 2

Next, isolate y by dividing both sides by 3.

3y/3 ≤ 2/3

y ≤ 2/3

There is your answer, English equals y, so the maximum time he can take on his English work is 2/3 of an hour or 40 minutes.

Dexter makes a scale drawing of his room. In real life, the room is 10 feet wide and 12 feet and 6 inches long. In Dexter's drawing, the room is 4 inches wide. What measure should the length be?

Answers

The length of modeled drawing room is 5 inches.

Given that, the room is 10 feet wide and 12 feet and 6 inches long.

What is scale factor?

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

So, scale factor = 4 inches

We know that, 1 feet = 12 inches

Now, scale factor = 4/(10×12)

= 4/120

= 1/30

Length = 1/30 ×(12 feet and 6 inches)

= 1/30 × (144+6)

= 1/30 × 150

= 5 inches

Therefore, the length of modeled drawing room is 5 inches.
