<h2>Answer:</h2>

<u>Original price of a phone</u> = $42000.

<u>Tax </u><u>on p</u><u>hone</u> = 2%.

so, <u>Cost price = Original price </u><u>+</u><u> tax% deduction</u>

= $129.99 + 2% of $129.99

= $129.99 + 2/100 × 129.99

= $129.99 + 1.2999 × 2

= $129.99 + $2.59

= $132.58.

Add 3/7 + 8/9 . Simplify the answer and write as a mixed number
Fudgin [204]
You will get both of the fractions over the same denominator, so it will be 27/63 and 56/63, then you will add the two numerators, so it will then come out to 83/63, and you will then simplify that by subtracting 63 from 83, and will get 1  20/63

A rental car company charges $68.80 per day to rent a car and $0.08
viktelen [127]

Answer:

  • 5 days maximum

Step-by-step explanation:

<u>Given</u>

  • Daily charge = $68.80
  • Charge per mile = $0.08
  • Target distance = 325 miles
  • Money limit = $370

<u>Required inequality:</u>

  • 68.8d + 325*0.08 ≤ 370

<u>Solving for d:</u>

  • 68.8d + 26 ≤ 370
  • 68.8d ≤ 344
  • d ≤ 344/68.8
  • d ≤ 5

Up to 5 days is the answer

Find the center and radius of the circle described by the equation
Debora [2.8K]
Complete the square fr x and y's sepreatly to get into form
(x-h)²+(y-k)²=r²
the center is (h,k) and radius is r

so


group x's and y's seperatly
(4x²-10x)+(4y²+24y)+133/4=0
undistribute leading confident from each
4(x²-2.5x)+4(y²+6y)+133/4=0
take 1/2 of each linear confident and square it and add negative and positive inside the parenthasees
-2.5/2=-1.25 (-1.25)²=1.5625
6/2=3, 3²=9
4(x²-2.5x+1.5625-1.5625)+4(y²+6y+9-9)+133/4=0
factor perfect squares
4((x-1.25)²-1.5625)+4((y+3)²-9)+133/4=0
expand
4(x-1.25)²-6.25+4(y+3)²-36+133/4=0
4(x-1.25)²+4(y+3)²-9=0
add 9 to both sides
4(x-1.25)²+4(y+3)²=9
divide both sides by 4
(x-1.25)²+(y+3)²=9/4
(x-1.25)²+(y+3)²=(3/2)²

the center is (1.25,-3) and the radius is 1.5
