Answer:
Width = ft
Step-by-step explanation:
The tank holds 150 gallons of water.
7.5 gallons holds 1 ft³ of water.
So 150 gallons will hold;
× 1 ft³ = 20 ft³
The volume of the tank = Length(l) × Width(w) × Height(h) = 20 ft³
i.e 5 ft × w × 3 ft = 20 ft³
15w ft² = 20 ft³
w = = ft

Answer:
f=24km/h
Step-by-step explanation:
Alright, here's what we know.
He travels 2 hours at a fast speed, lets call that speed f km/h
He then travels 3 hours at (f-10) km/h
In these 5 hours, he travels 90km
So we have the formula velocity = distance/time. If you don't know where that formula comes from, let me know and I'll explain.
So we have:
d and t are given to us as 90 and 5 respectively
v is going to be his average speed, so we take 2 times the fast speed plus 3 times the slower speed and divide it by 5. This gives us the average speed he traveled over the 5 hours.
2f+3f−30=90 by cancelling the 5's in the denominator and expanding 3(f−10)
5f=120
f=24km/h
So his faster speed is 24 km/h. Let me know if this solution did not make sense to you at any point.
Answer:
6 and 12
Step-by-step explanation:
n + (n+6) = 18
2n +6 =18
2n = 12
n = 6
6+(6+6) = 18
6+12 = 18
18=18
