Answer:
100 girls
Step-by-step explanation:
The ratio of boys : girls is 2 : 5.
In other words, boys are 2 parts of the school while girls are 5 parts of the school.
Since there are 40 boys, 2 parts of the school is 40. Thus:
1 part is 20.
Since there are 5 parts girls, there are
100 girls.
Answer: 100 girls
Answer:
3
Step-by-step explanation:
Given the question :
The value of n is a distance of 3 units from 1 an 1/2 on a number line click on the number line to the possible values of n
From the context of the expression:
n is the distance which exists between 1 1/2 and 3 units from it;
Which may be ;
1 1/2 - - - - (1 1/2 + 3) = 4 1/2
1 1/2 - - - - - (3 - 1 1/2)
Either way, there exists a distance of 3 units between 1 1/2 and 3 units from it.
Hence, n = 3
He earned 32 for 4 hours, so you have 32/4.
Then you want to find the number of hours to make 80, so you have 80/h.
Set them to equal each other:
32/4 = 80/h
Now cross multiply:
(32 * h) / (4 *80)
Simplify:
32h = 320
Divide both sides by 32:
h = 320 / 32
h = 10
He will need to work 10 hours.
