21/356 because there are 21 kids and 365 days in a year
ANSWER
2(s+175)
EXPLANATION
The total amount of garbage thrown away at the school each day is the amount of garbage thrown away by the students plus the amount of garbage thrown away by non-students.
total = lb students + lb non-students
lb students is 2s as each student throws away two pounds a day.
lb non-students is 350. Therefore, the total amount of pounds of garbage thrown away each day is
total = 2s + 350
We can factor out a 2 from this expression as each term is divisible by 2 and that is the greatest common factor. We end up with
total = 2(s+175)
Answer:
1500+337.50 = $1,837.5
Step-by-step explanation:
You want to calculate the interest on $1500 at 4.5% interest per year after 5 year(s).
The formula we'll use for this is the simple interest formula, or:
<em>
I = P x r x t</em>
Where:
P is the principal amount, $1500.00.
r is the interest rate, 4.5% per year, or in decimal form, 4.5/100=0.045.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 1500 × 0.045 × 5 to get that:
The interest is: $337.50
Answer:
54 teachers
Step-by-step explanation:
Step one:
given data
The ratio of teachers to students on a field trip to New York City is 2 to 9.
That is the ratio is 2:9
We are told that there are 243 students
Required
We want to find the number of teachers
Step two:
Applying the part to part method we have
let the number of teachers be x
2/9= x/243
cross multiply we have
9x= 243*2
9x= 486
divide both sides by 9
x= 54
Hence there are 54 teachers
