Answer 1
Answer: 5 x 2/4 = 5/1 x 2/4 =  2 2/4 = 2 1/2
8)   not equal, not equal, equal
9)   1/8 of a pound is in each portion
10)   $3.75

I hope this helps you. With number 8, all i did was simplify the fractions and see if the can be equal to the first fraction in the whole question and determined my answer by that. For number 9, i divided 1/2 of a pound by 2 and got 1/4 of a pound, and then divided that by 2, and i got the answer of 1/8 of a pound. When it come to number 10, i multiplied $0.50 by 7 and got $3.50, and since the last part was half a foot i knew it would cost $0.25 instead of $0.50, so i just added that to the answer and got the end result of $3.75.

Help no guessing please explain how to solveJulie earned simple interest on $8250 with an annual interest rate of 3.9% for 7 years. How much did she earn in interest? Round your answer to the nearest cent.

Answer_______

Answers

ok so easy

I=PRT
t=time=7
r=rate3.9%=0.039
p=principal=8250

I=8250 times 0.039 times 7
I=8250 times 0.273
I=2252.25

$2252.25
We meet again.  I see you are asking about another similar equation, and I will give you the same response I did last time.  You simply plug the values into the equation in solve, so it would look like this:
I=8,250*.039*7.
And you can do the rest.  I hope this was helpful, have a nice day! :)

McDonald's has sold more than a billion hamburgers. If it were possible to eat a hamburger every minute of every day without stopping, how many years would it take to eat a billion hamburgers

Answers


Generically, you're asking how many years make 1 billion minutes.

(1 x 10⁹ minutes) x (1hr/60min) x (1 da/24hr) x (1yr/365.25da) =

           (1 x 10⁹) / (60 x 24 x 365.25)  years =  1,901.3 years (rounded)
1 day = 24 hours
24 hours =1440 minutes

1 year = 365 days
365 x 1,440 = 525, 600 minutes per year.

it means, 525600 hamburger per year
