It costs $5820 to get new windows for a certain house. Each of the 28 windows costs the same amount.
Marina86 [1]
Alright well for (A) you will round $5280 to $5300. Then you multiply $5300 by 28.

For (B) you just round up. So again $5280 rounds up to $5300.

What's the answer to this
timofeeve [1]

Answer:

AC ≈ 17.3 , BC ≈ 5.3

Step-by-step explanation:

using the tangent ratio in right triangle ACD

tan51° = \frac{opposite}{adjacent} = \frac{AC}{AD} = \frac{AC}{14} ( multiply both sides by 14 )

14 × tan51° = AC , then

AC ≈ 17.3 ( to the nearest tenth )

using the cosine ratio in right triangle ABC

cos72° = \frac{adjacent}{hypotenuse} = \frac{BC}{AC} = \frac{BC}{17.3} ( multiply both sides by 17.3 )

17.3 × cos72° = BC , then

BC ≈ 5.3 ( to the nearest tenth )
