3 10 / 24 + 6 3 /6 =

1 answer:

6 0

Well first we need to make our fractions have a common denominator. Since 24 is the higher one we will turn 6 into 24. In order to do that we have to multiply our top number and bottom number by 4. 4x6=24 and 3x4=12 therefore our new fraction is 12/24. Now add 6 and 3 which is 9. After adding 6 and 3 we add our fractions. Adding fractions is kind of odd because you only add the top numbers. So, we add 10 and 12 to get 22. Our final step is figuring out if we can simplify the fraction which in this care we can! So, in order to simplify this fraction we divide by 2 which will then make our fraction 11/12 which can not be simplified. So your final answer would be 9 and 11/12. Hope this helps! :)

The ratio of girls to boys in a particular classroom is 8: 7. How many boys are in the class if there are 45 students?

Dmitry [639]

9514 1404 393

Answer:

Step-by-step explanation:

Rearranging the given ratio, we can find the ratio of boys to the total.

boys : (boys +girls) = 7 : (7+8) = 7 : 15

Then the number of boys is ...

(7/15)(45) = 21

There are 21 boys in the classroom.

What is x? I will give brainliest if you explain your answer.

horsena [70]

Answer:

x = {0, π/2, 3π/2, 2π}

Step-by-step explanation:

cotx cos x - cot x = 0
cotx( cosx - 1) = 0

1. cotx = 0

x = π/2 + πn
In the interval [0, 2π] we have π/2 and 3π/2

2. cosx = 1

x = 0 + 2πn
In the given interval we have 0 and 2π

So the solution set is:

x = {0, π/2, 3π/2, 2π}

Which is an example of discrete data?

poizon [28]

Discrete data in information that we collect that can be counted and that only has a certain number of value. EXAMPLES OF DISCRETE DATA: include the number of people in a class, test questions answered correctly, and home runs hit.

Hope this helps :)
