36/3 x 42/3 = 12yd x 14yd

12×14=168

you will need 168 square yards to recarpet the kindergarten.


2)
168×24.99=4198.32

it will cost $4198.32 to recarpet the kindergarten.


3)
3.5 is 35% of 10

4198.32÷3.5=1198.52

they will need to sell 1199 coupon books to completely pay for the the recarpeting.

The price of a cd was decreased by 20% to £7.68. What was the price before the decrease?
love history [14]

Answer:

£9.6

Step-by-step explanation:

x = the original price of a CD

£x = 100% of the original price

The price of a CD was decreased by 20% to £7.68.

This means:

£7.68 = 100% - 20%

£7.68 = 80% of the original price

From this, we will find 1% of the original price.

£7.68 ÷ 80 = 1%

£0.096 = 1%

Since the original price ( x ) = 100% of the original price, we will find 100% of the original price.

£0.096 × 100 = 100%

£9.6 = 100%

Therefore, the original price of a CD = £9.6

Your answers are
A = 35.7°
B = 67.6°
C = 76.7°

cosine law

a^2 = b^2 + c^2 -2bc \cos A \\
-2bc \cos A = a^2 - b^2 - c^2 \\ \\
\cos A = \dfrac{a^2 - b^2 - c^2}{-2bc} \\ \\
A = \cos^{-1}\left[ \dfrac{a^2 - b^2 - c^2}{-2bc} \right] \\ \\
A = \cos^{-1}\left[ \dfrac{12^2 - 19^2 - 20^2}{-2(19)(20)} \right]  \\ \\
A = 35.723697

A = 35.723697
sine law for the rest of the angles

\displaystyle
\frac{\sin B}{b} = \frac{\sin A}{a} \\ \\
\sin B = \frac{b \sin A}{a} \\ \\
B = \sin^{-1} \left[ \frac{b \sin A}{a}  \right] \\ \\
B = \sin^{-1} \left[ \frac{19 \sin 35.723697 }{12}  \right]  \\ \\
B \approx 67.58886795

B = 67.58886795
All angles in triangle sum to 180 so find C with that

A + B + C = 180
C = 180 - A - B
C = 180 - 35.723697 - 67.58886795
C = 76.7°
