Help Please: Two boats start their journey from the same point A and travel along directions AC and AD, as shown below: What is the distance, CD, between the boats? 230.9ft 284.3ft 115.5ft 173.2ft
1 answer:
Answer:
230.9 ft
Step-by-step explanation:
The side ratios of a 30°-60°-90° triangle are 1 : √3 : 2
In ∆ABC, BC = AB/√3 ≈ 115.47 ft
In ∆ABD, BD = AB√3 ≈ 346.41 ft
Then the length CD is ...
346.41 ft -115.47 ft = 230.94 ft
The distance CD is about 230.9 ft .

equation would be 23 plus 9 equals 32 or p, the number of cans she bought
Step-by-step explanation:
You can first multiply the width by two. Then you subtract that from you perimeter to figure out your length. Whatever number you get divide it by two and there's your length.
Example:
Perimeter =30 Width=5
5 times 2= 10
30-10=20
20/2=10
So your length equals 10.
I hope this helps!
V = pi * r^2 *h
where r is the radius and h is the height of the cylinder
V = pi * 7^2 *4
V = pi* 49*4
pi is approximated by 3.14 or 22/7
V = 22/7 * 49 * 4
V = 616 units ^3
