You need a ruler and a pencil. Oh and paper. Make sure that each side is equal to 4 inches. Then make a scale of 1:12, meaning 1 inch=1 foot.
Answer:
There are 40 problems on the test
Step-by-step explanation:
Let p = the number of problems on the test
The number of problems on the test times the percent correct is the number correct
p * 85% = 34
p * .85 = 34
Divide each side by .85
p * .85/.85 = 34/.85
p = 40
There are 40 problems on the test
If you have a ratio like 1 yard for 3 feet you can graph that to get a better understanding of size
Math:
7 dogs, 3 cats, 5 birds. In total, there are 15 animals all together.
So ignore the 3 and 5 those are in there to throw you off. To get the percentage, you do 7/15
So you'd get 0.4666667
Answer: 0.467
Rounded Answer: 0.47 (Or 47% B)
Let me help you, but first I will explain the formula used to calculate monthly compound interest.
The formula used to calculate compound monthly compound interest is
a=p(1+r/n)^nt
P Represents the principal
R Represents the rate (in decimal)
N is basically 12 months
T Represents the time (in years)
Let's plug the numbers in.
First statement
"His bank has offered him a loan at 13% interest for 36 months"
12000(1+.13/12)^(12)(3)
12000(1+.13/12)^(12)(3) = $17,686.64
Second statement
"12% interest for 60 months"
Plug in the numbers into the formula.
12000(1+.12/12)^(12)(5)
12000(1+.12/12)^(12)(5) = 21,000.36
<u>Answer</u>
The answer would be "13% interest for 36 months" as it is much lower compared to the other statement.
