Answer:
Yes it is an integer
Step-by-step explanation:
Answer:
Part 1)
The equation by factorization is
Both values of x are
Part 2) The dimensions of the cuboid are
, 
and 
Step-by-step explanation:
step 1
we know that
The volume of the cuboid is equal to
substitute the given values
so
Complete the square
square root both sides
so
therefore
The equation by factorization is
step 2
Find the dimensions of the cuboid
The dimensions are
M(h)=5h
that is marcia's number of candles where she makes 5 candles per hour (h)
kevin makes 4 but already did 7 so
k(h)=4h+7
when will they have same numbre of candles?
when will m(h)=k(h)
set equal
5h=4h+7
minus 4h from both sides
1h=7
answer is 7 hours
system of equation is
m=5h
k=4h+7
find what value of h makes m=k true
answer is 7 hours
42.9 is greater because 42.7<42.9
You are to calculate the # of students, based upon the starting volume of juice and the amount each student receives.
22 1/2 cups
This # of students is equal to ------------------------------
[1 1/4 cup / student ]
and this could be found easily by dividing 22.5 by 1.25: 18. There are 18 students.
