8 minutes for 10 problems

We want to find the unit rate.
Basically, how long does it take to do just <em>1</em> problem?

Divide each number by 10.

8/10 minute for 1 problem

This could simplify to 4/5 because both the top and bottom are divisible by 2, but since 8/10 is one of the answers, pick that.

What is the theoretical probability that you will get a sum of 7? P(sum of 7)=
hammer [34]

Answer:

\frac{12}{36} or \frac{1}{3}

Step-by-step explanation:

Notice that there are 6 sums of 7 on the table provided. For example rolling a 1 and then a 6 would produce a sum of 7.

The reason the answer is 12 and not 6 is that you need to double it for the two dice. Let's say one die was green and the other was blue. The green die could be the 1 and the blue die could be the 6. That is one favorable outcome, but it could be switched. Maybe the green die was 6 and the blue die was 1.

dlinn [17]

Answer:

1. V = πr²h

2. dv/dt = πr²dh/dt

3. dv/dt = 113.04

Step-by-step explanation:

We have these information

Radius R = 3cm

Height = h

Volume = V

We have been given dh/dt = 4cm

1.

An equation relating V, r, h

Volume of cylinder = πr²h

2.

The related rates equation

dv/dt = πr²dh/dt

dv/dt = π3²dh/dt

3. Continuing from number 2 above, we have

dv/dt = π3²dh/dt

= π9x4

= 3.14x9x4

= 113.04

These are the answers to the questions
