Alexeev081 [22]

Answer:

Well, I don't think I can remember EVERY skill I was taught through the years but in Kindergarten we used Number Sense so we could accurately... also there's estimation and of course PEMDAS. I've also learned how to round up so that the solution is at least around those numbers if the skill is to be applied.

Step-by-step explanation:

I'm not sure if this'll help but go ahead and have it... just try and change it a bit so they don't get ya for plagirism

Two boats start their journey from the same point A and travel along directions AC and AD, as shown below: ABC is a right triang
Dmitriy789 [7]

*See the figure in the attachment below

Answer:

346.4 ft

Step-by-step Explanation:

The distance between the boats, CD = BD - BC

Using trigonometric ratio formula, find the length of BD in right triangle ∆ABD, and also find the length of BC in right triangle ABC.

Length of BD in triangle ABD:

Opposite length to <30° = 300 ft

Adjacent length = BD

tan(30) = \frac{300}{BD}

BD*tan(30) = 300

Divide both sides by tan(30)

\frac{BD*tan(30)}{tan(30)} = \frac{300}{tan(30)}

BD = 519.6 ft (nearest tenth)

Length of BC in triangle ABC:

Opposite length to <60° = 300 ft

Adjacent length = BC

tan(60) = \frac{300}{BC}

BC*tan(60) = 300

Divide both sides by tan(60)

\frac{BC*tan(60)}{tan(60)} = \frac{300}{tan(60)}

BC = 173.2 ft (nearest tenth)

distance between, CD, between the boats = BD - BC

= 519.6 - 173.2 = 346.4 ft

Helen [10]

Answer:

x+4=20 is a solution to 5(x+4)=100.

Step-by-step explanation:

Following PEMDAS, divide 5 from both sides of the equation 5(x+4)=100, and you have x+4=20 remaining.

This means that both equations have the same solution.
