Answer:
7/165
Step-by-step explanation:
This is a mixed recurring decimal (the zero is not repeating)
We take number after the decimal point 042
then we subtract the non repeating.In this case is 0 so we not subtract anything
This will be the numerator 42
Now ,the denominator:
For each repeating decimal we write a 9 (in this case 2 nines)
For each non repeating decimal we write a zero
Denominator is 990
42/990 = 7/165
7:165 = 0.0424242......
I can't directly tell you the answer, but I can help you for how to do it.
So every single time you want to find the rate of change (slope) label 2 points with x1, y1, x2 and y2. We can use the point-slope form to sind the slope:
y1-y2/x1-x2
And we just need to plug in the point to get the Y intercept.
When the x is 0, the y value will be the y-intercept.
The slope intercept form is: y=Mx+B. M stands for slope and B stand for y-intercept. Just plug the slope and y-intercept in and get the answer.
Here are some
1 ) 4 ( x - 3 )
2 ) 10 x - 2 x - 12
3 ) 8 x - 4 - 8
Answer:
D. 30 kilometers
Step-by-step explanation:
Add all the given distances relative to the map together:
6.5 + 9.5 + 4 = 20
Multiply that by the scale to convert centimeters to kilometers:
20 x 1.5 = <u>30</u>
Your answer is 30 kilometers.
You also could have gotten the same answer by multiplying each number by the scale and then adding those together but that is slightly more work so the way I showed is more convenient.
