-4.375
Step-by-step explanation:
The answer to this question is 90 mm
Seun : Tayo : Dayo
4 : 3 : 2
Total parts = 4 + 3 + 2 = 9
9 parts = N120
1 part = N120 ÷ 9 = N12.33
Seun = 4 parts = N12.33 x 4 = N53.33
Dayo = 2 parts = N12.33 x 2 = N26.67
N53.33 + 26.67 = N80
Answer: N80
Answer:
-8 1/2 ft / min
Step-by-step explanation:
X = second diver rate
1 1/2 X = -12 3/4
3/2 X = - 51/4
X = - 51/4 * 2/3 = - 102/12 = -8 1/2 ft / min
