B.3.75%
C.3.9%
D.6%

Answers

Answer 1
Answer: Percentage error =(error)/(actual measurement) * 100
Here error = 16 - 15.4 = 0.6
Therefore, percentage error =(0.6)/(15.4) * 100=0.039 * 100
=3.9%

Paint costs $29.95 per gallon. Nikki needs 12.25 gallons to complete a painting project. How much will Nikki spend on paint? (Round to the nearest penny)

Answers

Since you can't by 1/4 of a bucket of paint you round 12 up to 13. next you multiply the cost of each gallon (29.95) by the number needed (13) when you do this you get 29.95*13=398.35 so she would spend $398.35

Final answer:

Nikki will spend approximately $366.56 on her painting project, taking into account the cost of $29.95 per gallon and the need for 12.25 gallons.

Explanation:

This question requires multiplication to ascertain the total amount Nikki will spend on her painting project.Nikki needs 12.25 gallons of paint to complete a painting project. The cost of paint is $29.95 per gallon With each gallon of paint costing $29.95, and Nikki needing 12.25 gallons, you would multiply these two values together. So, $29.95 * 12.25 equals approximately $366.56

What is reciprocal of a fraction?

At first, it is important to know about fraction.

Suppose there is a collection of objects and a part of the collection has to be taken. The part which is taken is called fraction. In other words, part of a whole is called fraction.

The upper part of the fraction is called numerator and the lower part of the fraction is called denominator.

For example: (4)/(7) is a fraction. Here, 4 is the numerator of the fraction and 7 is the denominator of the fraction.

Let p be a fraction. Reciprocal of p is a fraction in which if the fraction is multiplied by p, the result obtained is 1 (multiplicative identity)

Here,

3(1)/(4) = (13)/(4)

Let the reciprocal of (13)/(4) be x

(13)/(4) * x = 1\n\n13x = 1* 4\n\n13x = 4\n\nx = (4)/(13)

Reciprocal of 3(1)/(4) is (4)/(13)
