<span>h = Williams hours
h + 2.5 = Jose's hours because he worked 2.5 hours more than William, so you add 2.5 to William's hours (which is represented by h) to get Jose's hours
then you add them together..</span><span>

Answer:
A. $3,984
Step-by-step explanation:
The amount of interest is computed from ...
I = Prt
For the given values, the interest is ...
I = $3600×0.08×(16/12) = $384
Then the total amount that needs to be repaid is ...
Principal + Interest = $3600 +384 = $3,984
_____
The time period is 16 months, so is 16/12 years.
The time periods of the interest rate and "t" in the formula must match. If the interest rate is an annual rate, then "t" is in years. If the interest rate is a monthly rate, then "t" is the number of months.
Answer:
628
Step-by-step explanation:
Deposit means money is going into the bank so add 129 onto 499
(b) writing a cheque means money is coming out of the bank so subtract 24 from your previous answer.
628 - 24 = 604
(c) again, this money is coming out so take 151 away from 604
(d) round 604 to the nearest hundred
(it's between 600 and 610 but which is it closest to?)
5,7
it aint even that hard bro
Answer:
29 cans
Step-by-step explanation:
To solve this problem we must use Heron's formula; A = 
S = 1/2 the perimeter of the given triangle
a, b, c = the measurements of the three given sides
The first step to solving this question is first finding the perimeter.
P = 65m + 74m + 67m
P = 206m
Now that we have our perimeter, we must divide P by 2 to get S.
S = 206/2
S = 103
Now we plug our numbers into Heron's formula.
A = 
A = 
A = 
A = 
A = 
Find the square root of this number.
A ≈ 2021.43909134... m²
If a can of paint covers 70 square meters, then you will need to figure out how many cans you need. This can be done by dividing the overall area of the triangle by the area that a single can of paint can cover.
= 28.8777013049...
We know we can't buy 28.87... of a can (people simply do not sell parts of cans or half-full containers... unless its a bag of lays chips and their 80% air nonsense...) so we must round up to the nearest whole number.
28.87... = 29
Thus we finally have our answer: 29 cans of paint!
