Kevin drove for 4 hours and then stopped to eat dinner. The total distance he had driven at different time intervals is shown on

natta225 [31]

Answer:

If you want a simple average, you can add all the speeds you see and divide them by the number of how many they are.

So firstly you have to calculate the speed of the first point, which is:

20 miles/0.5 hour

That means: 40 miles/hour

That would be your first "speed"

Then you calculate all of them :speed1+speed2+speed3 = something.

As an example: 20miles/hr + 40miles/hr+0miles/hr = 60miles/hr

Then, you divide it by how many "speeds" they are: 60miles/hr divided by 3 if I continue my previous example.

It is my first answer, and I hope I could help you a bit!

Sorry for the awkward English, as it is not my mother tongue.

Which sequence explains a geometric method of determining 3 - 17i/2 +2i?

never [62]

Answer:

That would be D.

Step-by-step explanation:

first, turn both to polar form. Then you plot the first one and scale by the second. also, using a Rectangular to Polar calculator, we can see that 2.82 is 2 sqrt 2, so it cannot be A or B. It also can't be C since you graph 3-17i first.

Alice has a total of 12 dimes and nickels. She has 2 more nickels than dimes

valkas [14]

This is a problem of system of linear equations in two variables. This concept of mathematics is very useful in real-life problems. You can solve a system by finding the solution. A solution of a system are the values of the variables that satisfies each equation in the system. So by knowing these concepts we can get a system of equation by analyzing each statement step by step, that is:

1. Alice has a total of 12 dimes and nickels.

Let the variables:

$D: Dimes \\ N:Nickles$

1st. Equation:

$D+N=12$

2. She has 2 more nickels than dimes

2nd Equation:

$N=D+2$

Therefore our system of linear equations is:

 $(1) \ D+N=12 \\ (2) \ N=D+2 \\ \\ Substituting \ (2) \ in \ (1): \\ D+(D+2)=12 \therefore 2D=10 \therefore D=5 \\ \\ Solving \ for \ N \ in \ (2): \\ N=5+2=7$

Conclusion:

Alice has 5 dimes and 7 nickels.
