An oil tank has to be drained for maintenance. The tank is shaped like a cylinder that is 3.5 ft long with a diameter of 1.8 ft.

Suppose oil is drained at a rate of
1.7 n' per minute. If the tank starts completely full, how many minutes will it take to empty the tank?
Use the value 3.14 for at, and round your answer to the nearest minute. Do not round any intermediate computations.

Answer:

5 minutes

Step-by-step explanation:

Volume of cylinder = πr²h

Radius, r = diameter / 2 = 1.8 /2 = 0.9

Volume of cylinder = 3.14 * 0.9² * 3.5

Volume = 8.9019 feet³

Drain rate = 1.7 ft per minute

Volume / drain rate

8.9019 / 1.7

= 5.2364117

= 5 minutes (nearest minute)

Answer:

v=5.42m/s

Step-by-Step Explanation:

We can use conservation of energy to solve this  

mgh=1/2mv^2

2gh=v^2

v=sqrt(2gh)

v=sqrt[2*9.8m/s^2*(6.5-5)]

v=5.42m/s

A box of oat cereal costs $3.90 for 15 ounces. A box of rice of cereal costs $3.30 for 11 ounces. Which box of cereal costs less
Firlakuza [10]

Answer:

The cost of per ounce of oat cereal is $0.04 less than per ounce cost of rice.

Step-by-step explanation:

Given:

Cost of 15 ounces of oat cereal box = $3.90

Cost of 11 ounces of rice box = $3.30

To compare the unit prices of the the boxes.

Solution:

Using unitary method to find the unit prices:

If 15 ounce of oat box cost =$3.90

∴ 1 ounce of oat cereal would cost = \$\frac{3.90}{15}=\$0.26

∴ Per ounce cost of oat cereal = $0.26

If 11 ounce of rice box cost =$3.30

∴ 1 ounce of rice would cost = \$\frac{3.30}{11}=\$0.3

∴ Per ounce cost of rice = $0.3

Difference in unit costs of oat and rice = \$0.3-\$0.26=\$0.04

On comparing the the unit costs of oats and rice, we find out that the cost of per ounce of oat cereal is $0.04 less than per ounce cost of rice.

Write 2,670,000 in scientific notation.
hjlf
Scientific notation is just rewritten so that it has a single digit in front of the decimal and that this is multiplied by a power of ten that makes this decimal equal to the original number.

In this case we have 2.67 million.  Well a million is equal to 10^6, because 10*10*10*10*10*10=one million.

So in scientific notation you would write:

2.67X10^6
