Answer:
- 4:5
- 16:20
- 32:40
Step-by-step explanation:
- 8 ÷ 2 = 4, 10 ÷ 2 = 5; put them together: 4:5
- 8 × 2 = 16, 10 × 2 = 20; put them together: 16:20
- 8 × 4 = 32, 10 × 4 = 40; put them together: 32:40
I hope this helps!

Answer: Distance between dolphin and helicopter = 93.5 feet
Explanation:
Distance at which dolphin swimming below the ocean= (-) 18 feet
(it is represented as the negative number as it denotes the distance below the ocean)
Distance at which helicopter is above the ocean = (+) 75.5 feet
(it is represented as the positive number as it denotes the distance above the ocean)
Distance between dolphin and helicopter = 75.5 - (-18) feet
= 75.5 + 18 feet
= 93.5 feet
A. theta = 210 (180 + 30) cos 30 = sqr(3)/2 sin 210 = -1/2
b. theta = 300 (360-60) tan 300 = - sqr(3)
c. sin = 1/2, cos = sqrt(3)/2, tan theta = 1/sqr(3), theta = 30
Miles in 3/5 hours = 3
Miles in a hour = 3 / 3/5
= 15/3
= 5 miles
