Answer:

12

Step-by-step explanation:

The 5 parts of the ratio represents 10 boys.

Divide number of boys by 5 to find the value of one part of the ratio.

\frac{10}{5} = 2 ← value of 1 part of the ratio

There are 6 parts of the ratio representing girls, thus

6 × 2 = 12 ← number of girls in the class

Pls help???????? need to have an explanation also
Ratling [72]

Answer:

I would say the answer is 40 cookies

Step-by-step explanation:

The reason I say this is because if you write out the amount of cookies she can make with 6 cups of flour, you would get 30/6. 30 and 6 are both divisible by 6, so if you divided both by 6 you will get 5/1. 1 times 8 is 8, so if you multiply 5 by 8 you will get 40 cookies.

Hope this helped!

i need help with a math problem right now it says A car rental agency advertised renting a car for $24.95 per day and $0.26 per
Dominik [7]

Answer:

He can drive 481 miles if David rents his car for three days

Step-by-step explanation:

This is true because if you take the 24.95 and multiply it by 3, because he rented it for three days, you'll get 74.85. Then you'll subtract 200 (the total money that can be spent) by 74.85 you'll get 125.15. Divide the remaining number, 125.15 by 0.26 to get 481.34. Take the decimals away because you don't need it, if you want to be sure it's correct you can multiply 481 by 0.26 to get 125.05 which is lower than 125.15 so it good because if you use 482 besides 481 it will be higher than the amount of money David can spend, that's why 481 is the right answer.
