If he uses 1 quarter, he has 40 cent left to make.He can do that in two ways, by using 2 dimes andall four nickels, or all 3 dimes snd 2 nickels.That's 2 ways.
If he uses both quarters, he has 15 cent left to make.He can do that in two ways by using 1 dime and 1 nickel,or no dimes and 3 nickels.That's 2 more ways.    So there are four ways to make 65 cents.

Answer:

4 ways

Step-by-step explanation:

Given that A vending machine accepts​ nickels, dimes, and quarters.

Purchase amt = 55 cents

Coins available = 4 nickels, 3 dimes and 2 qrs

Values                    5             10                 25

To give 55 cents, there are these possibilities

(2 qrs, 1 nickel)  or (1 qr, 2 dimes),  or (1 qr, 1 dime, 2 nickels) Or (1 qr, 4 nickels)

If he does not use a quarter, total value of dimes and nickels = 30+20 = 50 only.

Thus he has to use atleast one quarter.

Hence there are only 4 ways to do this

A number changed to 12.6 after it was rounded. To what place was the number rounded? Explain how you know.
Anton [14]
If 12.6 was rounded, that means that it was rounded to the tenths place.
You know this because the number has one decimal place, so that must be what it was rounded to.

I don't know how to solve this. Anything will help!​
tigry1 [53]
Hello :) to solve this you would have to do invert sin (51/55) on your calculator. When you do that you will get 68.013 so I would round that and say that the angle is 68 degrees

1) If P(x,-8) is a point on the line y=3x-2 what are the coordinates of P?
aleksandr82 [10.1K]
For part one, this means that the y value (the second value) is -8, and since we know that y=3x-2, we can say that -8=3x-2.
Adding 2 to both sides using the addition property of equality, we get -6=3x. Next, dividing by 3 using the division property of equality, we get -2=x. Therefore, plugging -2 in the point, we get (-2,-8) as our point.

For the second point, we have 2 as the x value, so we can plug that into 3x-2 to get 3*(2)-2=6-2=4 as the y value, making the point (2,4)
