Answer:
120 mph
Step-by-step explanation:
Distance = rate * time
D = 70 miles
t = 35 minutes
So that gives us:
70 mi = r(35 min)
Divide both sides by 35 min:
70/35 mi/min = r
simplify:
2 mi/min = r
If you wish to convert to miles per hour, remember that there are 60 minutes in an hour:
2 * 60 = 120
120 mph = r
Answer:
y=-3/4x+5
Step-by-step explanation:
3x+4y>20
4y>-3x+20
y>-3/4x+5
Answer:
26%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
Here, the new number is £504, and the old number is £400.
percent change = (£504 - £400)/(£400) * 100% =
= £104/£400 * 100% = 0.26 * 100% = 26%
