Answer:

$19575

$20945.25

Step-by-step explanation:

The current price of the car is $43500 but if I wait for 18 months, then it will be 55% cheaper.

So, the after 18 months the price of the car will be 43500(1 - \frac{55}{100}) = 19575 dollars.

If sales tax is 7%, then the total price of the car after waiting for 18 months will be 19575(1 + \frac{7}{100}) = 20945.25 dollars. (Answer)

Answer:

  • sin(X) = 6/7.5
  • XY = 4.5
  • cos(X) = 4.5/7.5
  • tan(X) = 6/4.5

Step-by-step explanation:

It is convenient to use the Pythagorean theorem to find XY to start with. That theorem tells you ...

  XZ² = YZ² + XY²

Solving for XY, you find ...

  XY² = XZ² - YZ²

  XY = √(XZ² - YZ²) = √(7.5² -6²) = √(56.25 -36) = √20.25

  XY = 4.5

The mnemonic SOH CAH TOA is very helpful here. It reminds you that ...

  Sin = Opposite/Hypotenuse

  sin(X) = 6/7.5

  Cos = Adjacent/Hypotenuse

  cos(X) = 4.5/7.5

  Tan = Opposite/Adjacent

  tan(X) = 6/4.5

_____

<em>Comment on the triangle and ratios</em>

The side lengths of this triangle are in the ratios ...

  XY : YZ : XZ = 3 : 4 : 5

If you recognize that the given sides are in the ratio 4 : 5, this tells you that you have a "3-4-5" right triangle with a scale factor of 1.5. At least, you can find XY = 1.5·3 = 4.5 with no further trouble.

The trig ratios could be reduced to sin(X) = 4/5; cos(X) = 3/5; tan(X) = 4/3, but the wording "don't simplify" suggests you want the numbers shown on the diagram, not their reduced ratios.

Leona [35]

Answer:

75+(-50)=75-50

Step-by-step explanation:

-let x be the profit made last week and y be the profit made this week.

-The two week profit/ loss is given as:

Profit=x+y

#We substitute actual values to calculate the profit/loss made:

Profit=x+y\\\\=75+(-50)\\\\=75-50\\\\=\$25

Hence, the two-week combined profit is $25.00
