Answer:
3 1/3 hours
Step-by-step explanation:
First we need to find how much she gets paid per hour. We can find this by diving the pay by the hours worked. Let x equal the pay per hour.
90/5=x
We can simplify the fraction by diving both the numerator and denominator by 5
(90/5)(5/5)=x
Do the division
18/1=x
Gianna gets paid 18 dollars per hour.
Now to find how much she needs to work we can divide the money she wants by the pay she gets per hour. Let y be the number of hours she needs to work.
60/18=y
turn into a mixed number
3 1/3=y
She would need to work 3 1/3 hours to make $60
Yes, it has the same result
look at the picture. the red triangle is the first image. the green one is the result of reflecting over x-axis. then if you reflect it over y-axis, it would be the purple triangle
if you had rotated the red triangle at first, it would have the same result
good luck
Answer:
20
Step-by-step explanation:
If 36 boys can conplete a task in 4 hours, then 19.35 boys could do it in 2 and a fourth hours.
You can set up an equation
A fourth of an hour is 15 minutes, so,
36 is to 4 as x is to 2.15, or,
36=4 as X=2.15
Multiply 2.15 by 36 (77.4)
77.4 divided by 4= 19.35.
Of course, you cannot have 19.35 boys, so there must be 20.
Hope this helps!
