A cylindrical water tank is being filled with a hose. The depth of the water increases by 1 1/4 ft per hour.How many hours will it take for the water level in the tank to be 3 1/2 ft deep?

Enter your answer as a mixed number in simplest form in the box.

It would really Help :) Thank you

Answers

Expressing the values as improper fractions for easy calculations:
Rate of filling = 5/4 feet per hour
Depth to be reached = 7/2 feet

Time taken = depth / rate
Time = 7/2 x 4/5
Time = 14/5 hours

As a mixed number:
Time = 2 4/5 hours

How do you solve for r in the formula a=pi r squared

Answers

To solve for y, all you have to do is just separate r from all of the others and make it equal to the rest of the equation. So first it was, a=pi*r squared. 
Divide by pi on each side, 
a/pi=r^2
Take the square root of each side;
square root of (a/pi) =r
and that's all

Nick randomly selects a digit from the set { 0 , 1 , 2 , . . . , 9 } and a letter from the set { A, B, C, . . ., Z } . Matthew will try to guess both the digit and the letter. Which expression gives the probability that Matthew will incorrectly guess both the digit and the letter?

Answers

Answer: 259/260 or 0.99615 (depending on which answer format your teacher wants)

There are 10 numbers in the set {0, 1, 2, ..., 9}. There are 26 letters in the set {A, B, C, ..., Z}. Multiply those values: 10*26 = 260. So there are 260 ways to pick a number followed by a letter. One example is 7P.

There is only one way Matthew can get the correct answer, and there are 260 - 1 = 259 ways to get the wrong answer. We divide 259 over 260 to get the probability of getting the incorrect answer, which is 259/260.

If you need this fraction in decimal form, then use a calculator to find that 259/260 = 0.99615 approximately
