Since 30 times 5= 150, he worked 150 hours for the rest of the week.
Answer:
He will have $39,750 at the end of five years.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:

In this question:

Interest earned:

Total amount:

He will have $39,750 at the end of five years.
Answer:
y = 5 ft
Step-by-step explanation:
We are looking for y.
This is a right triangle, so we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a = 12 and b = y c = 13
12^2 + y^2 = 13^2
144 + y^2 =169
Subtract 144 from each side
144-144 +y^2 = 169-144
y^2 = 25
Take the square root of each side
sqrt(y^2) = sqrt(25)
y = 5
Answer:
1320 ways
Step-by-step explanation:
Here we have a situation where 3 ribbons will be awarded to 3 of the 12 contestants. We can use the permutation formula, because the order of awarding the ribbons matters.
The permutation formula is:

n = 12
k = 3
Now that we have our variables, let's plug them into the formula.



So there are 1320 different ways that the contestants will be awarded.
