Answer:
12
Step-by-step explanation:
Subsitute for s and do the arithmetic.
.. A = 54s²
.. A = 54(1/3)² . . . . put 1/3 where s is
.. A = 54(1/9)
.. A = 6 . . . . . . square units
Her average rate is .615 miles per minute or about 37 miles per hour
This is the concept of algebra. Given that Holly has 30 pencils, the total number of pencils that Holly remained with after she gave her friends 6 pencils are:
Total=30-6=24 pencils
The fraction of pencils that need to be sharpened is 3/8
The number of pencils represented by this fraction will be:
(fraction of un-sharpened pencils)×(total number of remaining pencils)
3/8×24
=9 pencils
therefore we conclude that 9 pencils are not sharpened.
Answer:
400 employees
Step-by-step explanation:
Let the total no. of employees be x
From the information we get that,
30% of x= 120
Hence, 30/100x=120
x=120×100/30
x=400
