Solution :
Cost of carpeting per square yard = $ 15.00
<u>For 3 ft by 6 ft</u>
1 yard = 3 feet
∴ 1 feet = 
yard
So,
Therefore, area of 3 ft by 6 ft is = 
= 1 x 2
= 2 square yard
Therefore, cost of carpeting 2 square yard = 2 x 15
= $ 30
<u>For 9 ft by 12 ft</u>
1 yard = 3 feet
∴ 1 feet = yard
So,
Therefore, area of 9 ft by 12 ft is = 
= 3 x 4
= 12 square yard
Therefore, cost of carpeting 2 square yard = 12 x 15
= $ 180
Answer:
i = -6
Step-by-step explanation:
3 - 2i + 8 = 23
3 + 8 - 2i = 23
11 - 2i = 23
11 - 11 - 2i = 23 - 11
-2i = 12
-2i ÷ -2 = 12 ÷ -2
i = -6
Answer:
a.12/13
Step-by-step explanation:
- FORMULA: sine of an angle in a triangle is given by,
- here, in the given triangle PQR, for angle 'p'
opposite side= QR
adjacent side= PQ
hypotenuse=PR
- Therefore, sine of angle p=
- Thus, by using the above given formula, the sine of angle p in the triangle PQR is 12/13.
- hence, the trigonometric formulas as mentioned above should be remembered for sure to solve these type of problems
Answer:
- 3.68 feet using given equation (wrong)
- 12.5 feet using correct equation
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 <em>full revolutions</em>, so is back where it started — at 12.5 feet above the ground.
Let “T” represent the tax rate...
$150 x T = $7.50
Divide both sides by 150 to solve for T...
T = 7.5/150 = .05
So the tax is 5% (.05)
