Answer:

13%

Step-by-step explanation:

<u>Given:</u>

  • MP = 2080
  • Discount = d%
  • VAT = (d-2)%
  • Cost = 1997.84

<u>Apply discount:</u>

  • 2080 - d% = 2080*(1 - 0.01d)

<u>Add VAT:</u>

  • 2080*(1 - 0.01d) + (d - 2)%
  • 2080*(1 - 0.01d) * (1 + (d -2)/100)
  • 2080*(1 - 0.01d) * (0.98 + 0.01d) = 1997.84
  • (1 - 0.01d)(0.98 + 0.01d) = 1997.84/2080
  • 0.98 + 0.01d - 0.0098d - 0.0001d² = 0.9605
  • - 0.0001d² + 0.0002d + 0.98- 0.9605 = 0
  • 0.0001d²- 0.0002d - 0.0195 = 0
  • d² - 2d + 195 = 0

<u>Solving the quadratic equation we get:</u>

  • d = 15

<u>Then</u>

  • VAT rate = 15 - 2 = 13%

Answer:

x = 15

Step-by-step explanation:

8x + 9 and 51 are same- side interior angles and sum to 180° , then

8x + 9 + 51 = 180

8x + 60 = 180 ( subtract 60 from both sides )

8x = 120 ( divide both sides by 8 )

x = 15

The angles shown are

  • <QPR
  • <SPR

PR is the bisector of angle P

So

  • <P=<QPR+<SPR or =<QPS

I really need help with 1 and 2 please help me
AlekseyPX
R=50 because 8×50=400 so that is what r would equal
The exponent would be 5 the fifth power, because since the number your using to multiply it by is 5 and you are multiplying is by 5 fives it would be 5 to the fifth power
