How do I round these numbers?

Answers

Answer 1

Answer: Do your sum which is $329.69 subtract $59.63 then if the unit is 4 or less round your answer to the nearest ten eg, 103 would be rounded to 100. If the unit is 5 and above you would round your answer up eg, 437 would be rounded to 440.

Really need help lol...Kristin lives in Alaska. She drives a car with a 12-gallon fuel tank. When Kristin fills her empty gas tank in Alaska, she has to pay a federal gasoline
tax of $.18 (or 18 cents) per gallon, plus a state gas tax of 8 cents ($.08) per gallon. Her taxes paid for a gallon of gas equal 26 cents.

You can calculate the percentage of a purchase that goes to taxes by dividing the tax amount by the total sale price. If Kristin buys gas at $3.69 per gallon, which includes all taxes, what percentage of the price is the state tax? What percentage is the federal tax?

Answers

The first sentence in the second paragraph tells you exactly
how to work this exercise.

For every gallon:

Total sale price = $3.69

State tax = $0.08
Fraction that goes for state tax =

   (0.08 / 3.69) = 0.0217 = 2.17 % .

Federal tax = $0.18
Fraction that goes for federal tax =

   (0.18 / 3.69) = 0.0488 = 4.88 % .

Extra info that's not asked for:

Total amount of the sale price that goes for taxes =

   2.17% + 4.88% = 7.05 % .

Check that: (0.18 + 0.08) / (3.69)

   = ( 0.26 / 3.69 ) = 0.0705 = 7.05 %    yay!

Is the following relation a function ?

Yes

No

Answers

Answer:

Step-by-step explanation:

For a relation to be a function, each value of x must map to exactly one unique value of y

Here x = 4 and x = 0 both map to y = 3

Thus the relation is not a function

The slope of a direct variation function is -4. What is the equation of the function? y = 4 x
y = - 1/4 x
y = -4 x
y = x - 4

Answers

Answer:

y = -4 x

Step-by-step explanation:

the answer is y = x - 4
