Answer: they will meet after 3 hours.
Step-by-step explanation:
Let t represent the number of hours it will take them to meet.
A walker and a cyclist are 45 miles apart. If they move towards each other, in t hours, they would have covered a total of 45 miles
Distance = speed × time
They move towards each other with speeds of 5 mph and 10 mph respectively. It means that the distance covered by the walker in t hours is 5 × t = 5t
Also, the distance covered by the cyclist in t hours is 10 × t = 10t
Since the total distance covered us 45 miles, then
5t + 10t = 45
15t = 45
t = 45/15
t = 3 hours
Answer:
B. x = -6
Step-by-step explanation:
Use a graphing calculator such as desmos and enter each equation, you'll find the only one that falls on (-6, -9) and is perpendicular is B.
Answer: 0.22 kilolitre
Step-by-step explanation:
First, let’s find the volume of the tank. We know the volume of a cylinder is represented by the equation V=πr^2h,
Radius = 1 m
Height = 7 cm = .07 m
The tank is 0.22 cubic meters
Now that we found the volume, we will try to find how many liters are in the tank.
1 cubic meter = 1 kilolitre
So, 0.22 cu. m = 0.22 kilolitre
Answer:
4,680,000
Step-by-step explanation:
Whenever multiplying by 10s, 100s or 1000s, just add the 0s to the answer.
So 4680 plus three 0s would be 4,680,000
Have a good day :)
