Answer:
7 miles
Step-by-step explanation:
Distance = Rate times Time
Distance #1: (15 mph)(12/60 hr) = 3 miles
Distance #2: (12 mph)(20/60 hr) = 4 miles
Total distance ridden = 7 miles
Answer:
So, BC = BP+PC = 3 + 7 = 10 cm. Hence, the length of BC is 10 cm.
Step-by-step explanation:
Y=k+- a/b(x-h)
y=-+12x
12=a/b
a=12b
c²=a²+b²
(13,0) and (-13,0)
13²=(12b)²+b²
169=145b²
b= 13/12
169=a²+169/145
a²= 24336/145
x²/a²-y²/b²=1
145x²/24336 + 145y²/169=1
It is greater than the original because how much it is increasing (30%) is greater than how much it is decreasing (15%)
