Step-by-step explanation:
Given an expression that represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute is as follows :
-320+15y
We need to find the depth of submarine after 15 minutes.
Put y = 15 in the above expression.
-320+15y = -320+15(15)
= -320 + 225
= -95
Hence, the submarine is below sea level at 95 feet.
I think that to find the volume , you just need to do:
3.5 grams *1ml/8.75 g =0.4 ml
so you do it the way that the gram will be cancelled
Answer:
113
Step-by-step explanation:
4x-5=96, 4x = 101, x= 25.25
25.25 * 4 = 101
101 + 12 = 103
Answer:
2.6 hr
Step-by-step explanation:
distance / rate = time
rate = 75 + 95 = 170 mile/hr
distance = 442 miles
442 miles / 170 mile/hr = 2.6 hr
-1/5 * n ≤ 17
n ≥ -17/5 is the answer
