Mary bought a car for $9000 but sold it to naomi at a loss of 75% after it was involved in an accident. naomi repaired the car and sold it to heather for 175% more than she paid for it. calculate how much
heather paid for the car.

Heather paid $6187.5 for the car.

Step-by-step explanation:

Mary bought a car for $9000 but sold it to Naomi at a loss of 75% after it was involved in an accident. This means that the price at which Naomi bought the car is Mary's cost of buying the car minus 75% of Mary's cost of buying the car. It becomes

9000 - (75/100 × 9000) = 9000 - 6750 = $2250

Naomi repaired the car and sold it to Heather for 175% more than she paid for it. This means that price that Heather paid will be the sum of Mary's cost of buying the car and 175% of Mary's cost of buying the car.

It becomes

2250 + (175/100 × 2250) = 2250 + 3937.5 = 6187.5

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
