Suppose both factors in a multiplication problem are multiples of 10. Why might the number of zeroes in the product be different than the total number of zeroes in the factors?

Answers

Answer 1

Answer:

Multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.

Step-by-step explanation:

Let the first five multiples of ten be

10*1= 10

10*2= 20

10*3=30

10*4=40

10*5= 50

Suppose we chose 20 and 50.

Now multiplying 20 with 50 we get

20*50= 1000

IF we count the total number of zeros in the factors ( 20 and 50) they are 2.

But the number of zeros in the product (1000) are 3.

This is because when we multiply 2 with 5 we get 10 which adds to the existing number of zeros ( i.e 2) and we get a total of 3 zeros.

And multiplying 10 with 50 we get

10*50= 500

IF we count the total number of zeros in the factors ( 10 and 50) they are 2.

But the number of zeros in the product (500) are also 2.

This is because when we multiply 1 with 5 we get 5 which does not add to the existing number of zeros ( i.e 2) and the total number of zeros remain the same.

Similarly multiplying 20 with 30 we get

20*30= 600

IF we count the total number of zeros in the factors ( 20 and 30) they are 2.

But the number of zeros in the product (600) are also 2.

This is because when we multiply 2 with 3 we get 6 which does not have a zero and the total  number of zeros remain the same as in the factors.

So we see that multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.

What is the answer for "The points (4,r) and (8,-11) lie on a line with slope -3. Find the missing coordinate r."?​

Answers

Answer:

r = 1

Step-by-step explanation:

Use the slope formula:

m = (y₂ - y₁)/(x₂ - x₁)m = -3, x₁ = 4, y₁ = r, x₂ = 8, y₂ = -11

Substitute values and solve for r:

-3 = (-11 - r)/(8 - 4)-3 = -(11 + r)/411 + r = 12r = 12 - 11r = 1

Answer:

The answer to your question is R=1

Answer:

Step-by-step explanation:

Since this is a test/homework I'll give a hint.

For a linear equation, you have no idea what x and y is, but thats ok! The test itself has already given you 4 options, so you can just input the x/y coordinates, and if they fit, good for you! If they don't, you may need to try again. There are other more complex and faster ways, but they are (a) more complex.

X actually equals 16 becaausw if yiu add 16+4 you get 20 and then you have to multiply 20 by 1 and you get 20 so x=16

Answer:

x = 16

I dont quite understand the x = 48 situation? But thats wrong if that's your answe

Step-by-step explanation:

So you have to find out what x is

in order to do that you have to work out the equation and whatever you do to one side you must do to the other side

simplify 1(x+4) = 20

x + 4 = 20

in order to get rid of 4 on one side you have to subtract it on both sides

so x = 16

trigonometry problem​

Answers

Answer: -3π/2

Step-by-step explanation:

The unit circle is tricky, but here are some things to know:

When measuring angles, you usually move in the counter-clockwise direction. If you are moving clockwise (like shown in your picture), the angle will be negative. The unit circle is typically measured in radians, not degrees

              - To convert from radians to degrees, multiply by 180/π

              - To convert from degrees to radians, multiply by π/180

The whole unit circle measures 2π (360 degrees). This means that the positive x-axis can be referred to as 0 or 2π, the positive y-axis is referred to as π/2, the negative x-axis is referred to as π, and the negative y-axis is referred to as 3π/2.

              -If the angle is negative, switch the signs of the axis above.

The information above is all you need to answer the above question, but if you want/need anything else on the unit circle, just let me know.
