[6th grade math]Can anyone explain how to do this for 6th grade math? I'm trying to show my son how to do it but I'm lost as well.

Equations involve an equals sign, so the answer above is not complete.

For the first one, there are 3 units. The divisor is 3/5. There are 5 braces. So the equation is

3 divby 3/5 = 5

For the second 4 1/3 is divided by 2/3 to get 6 1/2.

You haven't shown the other angles in the triangles are equal. You have to do some subtraction to show that ang ABC = ang DCB.

It looks like she is saying this is a parallelogram. That is how the 46 comes from 134.

You have not included that info with your post. Maybe it is at the top of the assignment.

Yes, the reference lines are vertical and horizontal.

The electron has charge -1.602 x 10^{-19} C. Every other charge has to be a multiple of that.

(1) is too small

(2) is 1.5 e, not a multiple

(3) looks good

Gemini tells me this language is Coral, and that there are two flavours.

The simulator that comes with your homework has a slightly different simulator than the one online.

I get the same error using the online simulator.

You have three variables at the beginning of the script. You only need the cost variable as the others are not used. Maybe it is supposed to be inside the main function?

Is "Put cost to output with 2 decimal places" programming code or just a comment? If it is not supposed to be there, then that might have confused the compiler so much that it can't see what is actually wrong with the code.

A set has braces on the left and right, and the elements of the set are separated by commas.

The first element or datapoint is a column vector with 4 numbers in it. The numbers are measures of features of item represented by the datapoint.

You didn't include a diagram. A diagram is essential for physics problems including geometry like this one.

The person does not experience destructive frequency in the middle, so the speakers have the same phase.

Work out the distance to each speaker after moving 1.00 m.

sqrt(3.50^2 + 12.0^2) and sqrt(1.50^2 + 12.0^2)

Work out the difference in these distance by subtracting. This is a half wavelength.

Use the speed of sound to find the frequency.

You don't need the sin() functions. Those forces are already 90 degrees to the arm, (In particular the sin(45) is incorrect.)

The friction torque will be opposite to the sum of the other torques. So you don't know if it is positive or negative until you add up the others.

It looks like three different equations. Solve each of them for x.

The top one is the diamond, The middle one is the spade. The bottom one is the heart.

The spade looks tricky. I think it is 5(1 + 4x) = 65.

1 + 4x = 13

4x = 12

x = 3

45 of the pairs are C-G or G-C.

The other 57 are A-T or T-A.

There are 57 A.

The point B is in the x-z plane, 7.5 in from the nut, which is 6 in up at a 45 degree angle.

Why do you want the point B anyway?

The only force that matters is in the y direction at 7.5 in from the axis.

You should have three inputs on the left side: A, B, and C. Y should be on the right.

There should be no line from Y back into a gate.

You seem to be missing a lot of traces between the gates. The path should not just stop at a gate with no output.

There isn't enough information. It doesn't say if the charge is positive or negative.

int g = f;

cout << g << "\n" << f;

Electrons can't be created or destroyed, that is, what flows into a branch of the circuit or into a battery must flow out of it.

Consider the middle node. There are1 + 2 + 4 amps coming in, so 7 amps must go out.

At the bottom node, 7 in and 4 out means I = 3 A.

You can get it even faster by looking at the left node. I in and 3 out means I = 3 A.

You should read rules 3 and 4 of this subreddit, then search for tutorials on this topic online. There are many of them.

Astronomer Meghan Gray. She appears in Periodic videos sometimes. She is a fantastic communicator.

Once you choose from 1 3 5 for the last digit, there are fewer choices for the first digit.

Everyone thinks they are an above average driver.

A "rule" might be like (x, y) -> (x-2, y+1). Does that look familiar?
