Use 1/2ab sin C formula pls
Harman [31]

Step-by-step explanation:

area =  \frac{1}{2} a.b \sin(C)  \\ from \:cosine \: rule \\  {c}^{2}  =  {a}^{2}  +  {b}^{2}  - 2a.b \cos(C)  \\ 36 = 144 + 81 - (2 \times 12 \times 9) \cos(C)  \\ 189 = 216 \cos(C)  \\  \cos(C)  = 0.875 \\ C =  \cos {}^{ - 1} (0.875) \\ C = 28.96 \degree \\ area =  \frac{1}{2}  \times 144 \times 9 \times  \sin(28.96 \degree)  \\ area = 313.8 \: sq \: units

PLSSS? i dont really get it<br> Thanks
solmaris [256]

Answer:

A) 83 km/ hour

B) 2/7 penalties / game

C) $16 / CD

D) 9 donuts / box

Step-by-step explanation:

A)

For this question they are asking for the distance traveled in 1 hour.

Since 747km was travelled in 9 hours, we divide 747 by 9 to find the distance travelled in 1 hour

747 ÷ 9 = 83

The unit rate is 83 km/ hour

B)

You have to find the number of penalties per game

Like before divide 10 by 35:

10 ÷ 35 = 10/35 = 2/7

2/7 penalties / game

C)

Find the cost of 1 CD :

64 / 4 = 16

$16 / CD

D)

Find the amount of donuts per box:

72/8 = 9

9 donuts per box
