The volume of a box(V) varies directly with its length(l). If a box in the group has a length of 25 inches and k = 15, what is its volume? 375 cubic inches
455 cubic inches
1 2/3 cubic inches

Answers

Answer 1
Answer: The problem says that V(x)varies directly with its length. This is a proportionality problem. So, V(x) =kl. If you are given a length of 25 inches and a k (proportionality constant)of 15, you are required to find its volume V(x). 

V(x) = kl
V(x) = (15) (25 inches)
V(x) = 375 cubic inches 

The volume of the box is 375cubic inches.

To add any fraction You need to make sure that the denominator of the fractions are same. ( denominator in your sum is 19 )

10/19 + 3/19 ( we have the same denominator )
we can also write this problem like
( 10 + 3 ) / 19  { add the numerators together }
13 / 19

So correct option is B.

hope this helped..  :)
10/19+ 3/19 (common denominator is 19)
= (10+ 3)/19
= 13/19

The correct answer is B. 13/19.

A foot is 12 inches long. If an inch is about 2.54 centimeters long, how many centimeters are in a foot?

Answers

This is a question that needs understanding. The calculation part is comparatively easy. We should first concentrate and write down all the important information's that are given in the question.
1 foot = 12 inches
1 inch = 2.54 centimeters
The thing that needs to be determined is
1 foot = ? centimeters
Now
1 foot = 12 inches
           = (12 * 2.54) centimeters
           = 30.48 centimeters
So from the above deduction we can clearly see that 1 foot is equal to 30.48 centimeters. I hope the procedure is simple enough for you to understand.

Answer: 30.48

Step-by-step explanation: There are 2.54 centimeters in an inch so of you multiply that by 12 you get 30.48

Answers

Answer:

The answer is -3.1, or 3 1/10.Since diving a negative and a positive equals a negative, your quotient will be negative. You can start by removing the 0.5, and divide 15 by 5 which is 3. Then with the 0.5 from -15.5, divide it by 5 and you get 0.1. 3 plus 0.1 is 3.1, and since it has to be negative, it's -3.1.

consider a job that pays $100,000 per year federal income taxes 19% and state income tax is 7% what is the annual total of the required deductions of federal and state income tax

Answers

Answer:

$26,000.

Step-by-step explanation:

We have been given that a job that pays $100,000 per year federal income taxes 19% and state income tax is 7%.

The annual total of the required deductions of federal and state income tax would be 19\%+7\%=26\%.

To find the total amount, we will find 26% of $100,000.

(26)/(100)* \$100,000

26* \$1000

\$26,000

Therefore, the annual total of the required deductions of federal and state income tax is $26,000.
first multiply 100,000 and 19% equaling 19,000

Then multiply 100,00 and 7% equaling 7,000

Lastly add 7,000 and 19,00 together to get your answer

Answer: 26,000
