Answer:
1. 50 cm
2. 550 mm
3. 5000 mm
4. 5000 cm
5. 5000 m
Step-by-step explanation:
We can convert all the measures in same unit to arrange them one by one.
5000 cm:
As there are 10 millimeters in 1 cm,
5000 cm = 5000*10mm
=> 50000 mm
5000 meters:
As there are 100 cms in one meter
5000 m = 5000*100 cm
=> 500000 cm
Now to convert in millimeter
500000*10= 5000000 mm
50 cm:
50*10 = 500 mm
Then there is 550 mm and 5000 mm
So, the order from least to greatest is:
1. 500 mm which is equivalent of 50 cm
2. 550 mm
3. 5000 mm
4. 50000 mm which was equivalent of 5000 cm
5. 5000000 mm which was equivalent of 5000 m ..
Answer:
J- 2
Step-by-step explanation:
its where the line goes through the plot on the vertical axis
Answer:
x-int: (4, 0)
Step-by-step explanation:
First, we need to find the equation of the line.
The equation of a line is y = mx + b, where m is the slope and b is the y-intercept.
Thus, we need to find the slope first by using the slope formula:
or change in y / change in x
So we have: ![\frac{3-2}{1-2}=\frac{1}{-1}=-1=m](https://tex.z-dn.net/?f=%5Cfrac%7B3-2%7D%7B1-2%7D%3D%5Cfrac%7B1%7D%7B-1%7D%3D-1%3Dm)
We must plug in the slope to find the y-intercept:
![3=-1(1)+b\\3=-1+b\\4=b](https://tex.z-dn.net/?f=3%3D-1%281%29%2Bb%5C%5C3%3D-1%2Bb%5C%5C4%3Db)
So the equation of the line is y = -x + 4
The x-intercept means that the y coordinate is 0 so we can use the equation:
![0=-x+4\\-4=-x\\4=x](https://tex.z-dn.net/?f=0%3D-x%2B4%5C%5C-4%3D-x%5C%5C4%3Dx)
Answer:
7.5 days
Step-by-step explanation:
A working = 10 days
AB working = 4 days
AB = 4 --> 10B = 4
/10 /10
B = .4
AB = 3
A(.4) = 3
/.4 /.4
A working alone = 7 .5 days
<em>*pretty much solve for B and then equal AB to the amount of days the worked together before B left, 3 days, then it gives you the amount of time A must work to finish the house alone*</em>
