Why does the quotient of 8 ÷ 1 not change when we add a place value in the dividend and the divisor to make 80 ÷ 10?

Answer:

Basically this is because division can be thought of as how many times does the divisor have to be multiplied in order to produce the dividend.

So you would need to multiply 1 8 times in order to produce the dividend,

Similarly, 10 goes into 80 8 times. The zeros are simply cancelled out in the division.

What is 0.368 written in expanded form?
Goshia [24]
There are two methods that can be used to write 0.368 in expanded form.

Method-1:

Take the first number after the decimal point and divide it by 10. Take the second number after the decimal point and divide it by 100. Take the third number after the decimal point and divide it by 1000. Lastly, add all of them.

\frac{3}{10} +  \frac{6}{100} +  \frac{8}{1000} = 0.368

Method-2:
Multiply first number after decimal point with 0.1; multiply second number after decimal point with 0.01; multiply third number after decimal point with 0.001, and add them all.

(3 * 0.1) + (6 * 0.01) + (8 * 0.001) = 0.368

Plssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss help !!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer:

C.)  f(x) = −4x + 200

Step-by-step explanation:

Since the number is decreasing, you know the slope will be negative, eliminating the first two choices. The equation in the last choice does not match the given data, so it can be eliminated.

In other words, the easiest way to solve this problem is to check the answers against the given data.

_____

If you want to write the equation from scratch, you need to find the slope. That is ...

 (change in number of cars)/(change in weeks) = (184 -192)/(4 -2) = -8/2 = -4

This matches only one answer, but you can go on to finish the equation by starting with point-slope form:

 y -192 = -4(x -2)

 y = -4x +8 +192 . . . . add 192, eliminate parentheses

 y = -4x + 200 . . . . matches choice C.)
