Answer:

Answer 2
Answer:

Answer:

126 students

Step-by-step explanation:

Boys : Girls

7 : 11

How do you get from 7 to 49?

49 ÷ 7 = 7

Therefore, you should multiply the number of boys by 7.

Multiply:

7 : 11

7 × 7 = 49

49 : 11

Remember that whatever we do to the left, do to the right.

Multiply:

49 : 11

11 × 7 = 77

49 : 77

Now, let's add the number of boys and girls in the class to find the total number of students.

Add:

49 + 77 = 126

Therefore, there are 126 students in all.

does the train go 72mph for 2 hours as well? if so the answer would be 324 because you have to add 90 twice scene it goes at that speed for 2 hours thats 180. assuming  the train goes 72 mph for 2 hours it would be 144. then add 180 and 144 and you get 324 merry christmas and a happy newyear to you and your family

What is 3.4 divided by 4 and please show your work.

Answers

Ok so you set up the problem by putting the 3.4 inside the division box and put the 4 outside. 4 can't go into 3 so bring up the decimal but it can go into 34 so you find out that 4 can go into 34, 8 times so 34-32 is 2. Then you add a 0 after 3.4 so it would look like 3.40 and bring it down making a 20 and 4 can go into 20, 5 times. Making the answer .85

Final answer:

The result of the division operation 3.4 divided by 4 equals 0.85 after following the correct division steps.

Explanation:

To answer the math problem of 3.4 divided by 4, you can follow these steps:

  1. Put the numbers in the correct division format. In this case, 3.4 will be your dividend (the number that is being divided) and 4 will be your divisor (the number you are dividing by). So, it will look like this: 3.4 ÷ 4.
  2. Perform the division operation. In this case, when you divide 3.4 by 4 on a calculator, you get 0.85.

So, 3.4 divided by 4 = 0.85.
