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

Answer 1
Answer: 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

Hey There!

The answer to this problem is 2.7

Steps
1. Multiply 9*0.3

2. Once you multiply you should get 2.7

3. To solve step one you have to  pretend you are multiplying 9*3

4. The answer you get for step 3 is 27

5. After you get that answer (27) you must put the decimal in

6. After you do step 5 you should get 2.7

In conclusion, you're final answer should be 2.7

Hope This Helped ;)
This question is a little tricky.  This means that 9 is 3% of x stores.  3% is equal to 0.03, because a percent is a hundredth of a whole.  To find the percentage of x stores, we multiply the percent (in decimal form) by x.  This is equal to 9.  Our equation is 9=0.03x.  Now, all we have to do is divide 9 by 0.03, to isolate x, and we'll know the answer!  9/0.03=0.03x/0.03.  9/0.03=300.  So, x=300.

Answer: 300 stores

HELP!!! I NEED HELP ON MY EXAM. (15PTS)The population f(x), in millions, of State A of a country after x years is represented by the function shown below:

f(x) = 4(1.08)x

The graph shows the population g(x), in millions, of State B of the country after x years:

graph of exponential function g of x that curves up from left to right and goes through points 0 comma 2 and 9 comma 4

Which conclusion is correct about the populations of State A and State B?

The original population of State A was double the original population of State B.
The original population of State B was double the original population of State A.
The original population of State A was four times the original population of State B.
The original population of State A was equal to the original population of State B.

Answers

Answer:

its A

Step-by-step explanation:

I believe it's A because it started at 4 million where the graph started at 2 million. Therefore it would be double.

A farmer wants to fence in a section of land for a horse pasture. Fencing costs $31 per yard. How much will it cost to fence the pasture?

Answers

Answer:$13671

Step-by-step explanation:

The land the farmer will fence is equal to the sum of the lengths of all the sides of the land=330+330+330+189+144=1323 ft.

3 ft= 1 yard.

1 323 ft = 1323÷3=441 yards

Cost of fencing per yard is $31.

cost of fencing 441 yards=441x31=$13671.

330+330+330+144+189= 1323 ft

1323/3 = 441 yards

441yrds times $31 = $13671
