Bob and John are 450 feet apart when they start running towards each other. Bob runs at a speed of 11 feet per second, and John
Elena L [17]

Answer:

18 s

Step-by-step explanation:

We are given that

Distance between Bob and John=450 feet

Speed of Bob=11ft/s

Speed of John=14 ft/s

We have to find the time after they will meet when they are travel towards to each other.

Total distance traveled by Bob and John in 1 s=11+14=25 ft

25ft covered by Bob and John in 1 s

1 ft covered by Bob and John in \frac{1}{25}s

450 ft covered by Bob and John  in \frac{1}{25}\times 450=18 s

Hence, they will meet after 18 s.

A box contains10 pens, 5 of the pens are red, 4 are balck and 1 are bluem What is the probability of pulling out a black pen fir
antiseptic1488 [7]
Pulling out a black pen first will grant you a 40% chance of that occurring, then when you put it back the probability of you pulling out a red pen would be 50% so in decimal form these two values would be .40 and .50 multiply these two together you should get .20 or a 20% chance. Also a written fraction would be 1/5, all of which are valid answers.

The distance d of a particle moving in a straight line is given by d(t) = 2t^3 + 5t – 2, where t is given in seconds and d is me
Amanda [17]

Answer: 299 m/s

Step-by-step explanation:

The first step is to take the first derivative of the equation given. This will give us the equation for velocity which we will then substitute the 7 in for t.

To derive the equation you multiply the coefficient by the power of the variable, then subtract one from the variable.

v(t) = 6t^2 + 5

Now input 7 in for t to find the velocity.

v(7) = 6(7)^2 + 5

v(7) = 299 m/s
