103 times x hours=618
divide both sides by 103
x=618/103
x=6

No guessing please help no direct answer please help understandPeyton earned simple interest on $12,550 with an annual interest rate of 2.7% for 5 years. How much did she earn in interest? Round your answer to the nearest cent.

simple interest: I = P • r • t

Answer:_______

Answers

I was about to give you the formula you need,
but I see you already have it.

Simple interest: I = P · r · t

Interest = (Principle) · (rate) · (time)

The question says ...

Principle = $12,550
Rate = 2.7% (that's 0.027)
Time = 5 years

Now it's your turn.
Write the numbers into the formula, and calculate the interest.

The short answer is $1,694.25. To get this answer you plug it into the equation, so P would be $12,550, r would be .027, and t would be 5, so it would look like this in expanded form:
I=12,550*.027*5.
If you do the math from there, simple multiplication, you will get my answer. I hope this helps, have a nice day! :)

V=(1/3)hpir^2
r=7
h=21
V=(1/3)21pi7^2
V=7pi49
V=343pi cm^3

answer is D

V= π·r²·h/3 is the formula to calculate this.

So, V= 3.14 · 7² · 21/3

Remember to use PEMDAS

Exponents are first so:

V= 3.14 · 49 · 21/3

Now division:

V= 3.14 · 49 · 7

Now multiply from left to right:

V= 153.86 · 7

V= 1077.02

But, in your case, the answer is D) 343π cm³

A 1178 foot cable weighs 266 pounds. How many pounds will 36 inches of cable weight? round answer to two decimal places (1 pound equals 16 ounces)

Answers

Answer:

36 inches of cable weighs 0.68 lbs

Step-by-step explanation:

1178 ft cable weighs 266 lbs...and u want to know how many lbs a 36 inch cable weighs....

we need to turn ur ft to inches....1 ft = 12 inches....so 1178 ft = (1178 * 12) = 14,136 inches

14136 in. to 266 lbs = 36 in.to x lbs

14136 / 266 = 36 / x...cross multiply

14136x = (36)(266)

14136x = 9576

x = 9576 / 14136

x = 0.6774 rounds to 0.68 lbs <===
