Reptile [31]

Answer:

Step-by-step explanation:

First of all substitute the values to where ever you see their corresponding variables to make them multiply.

x = 9

y = 3

z = 2

so we get

8x as 8(9),

7z as 7(2)

2y as 2(3)

then the it's will be

8(9) - 7(2) + 2(3)

which is

72 - 14 + 6

finally we get

Without using a trigonometric ratio, find the distance from the ship to the buoy, B. Round the distance to the nearest tenth of

alexdok [17]

Without using the trigonometry ratio, we can find the distance between the ship and the buoy by:

the distance between City and Lemont SUBTRACT the vertical distance between City and the point parallel to the Ship

The distance between the City and Lemont can be worked out using the Sin rule
$\frac{57.8}{sin(36)}= \frac{City-Lemont}{sin(92)}$
$City-Lemont= \frac{57.9sin(92)}{sin(36)} = 98.27.....$ ≈98.3

The vertical distance between the City and the point parallel to the ship can be worked out using the Pythagoras theorem
$\sqrt{57.8^{2}- 44.6^{2} } =36.765...$ ≈36.8

The distance between the ship and the Buoy is given:
$98.3-36.8=61.5$ miles

The Chens bought their house for $240 000 twenty years ago. They just sold the house

serg [7]

The percent is the new value of the house of the price they paid 20 years ago is 216.67%.

<h3>Percentage</h3>

Old price = $240 000
New price = $520 000

percent is the new value of the house = New price / Old price

= 520,000 / 240,000 × 100

= 2.16666666666666

= 216.666666666666%

Approximately,

percent is the new value of the house = 216.67%

Therefore, the percent is the new value of the house of the price they paid 20 years ago is 216.67%.
