In expanded form, 310409 would be 300000+10000+400+9
Unless you want it as
3*100000+1*10000+4*100+9
Or even
3*10^5+1*10^4+4*10^2+9
Answer:
10cm, 16 cm, 18 cm,
Step-by-step explanation:
The lengths of the sides of a triangle are in the extended ratio 5: 8.9. The perimeter of the triangle is 44 cm.
Sum of proportion = 5 + 8 + 9
= 22
Length of side a
5/22 × 44 = 10 cm
Length of side b
8/22 × 44 = 16 cm
Length of side a
9/22 × 44 = 18 cm
The lengths of the sides of the triangle in cm are 10cm, 16 cm, 18 cm,
There are several different forms for the equation of a line. Point-Slope works pretty well for this one.
Remember, point-slope form looks like this:

Where the _1 means you sub in a point that matches that coordinate.
(x,y)
m, is the slope.
So an equation of the line would look like this:
(y - 2) = 1(x - 1)
The times 1 slope is implied, so you could also write it as:
(y - 2) = (x - 1)
(Removing the parenthesis is also acceptable, in this case)
Let's say you were not given it in point slope form. Then let's take the point slope form we made and put it into the slope intercept form by solving for y.
y -2 = x - 1
Solve for y by adding 2 on both sides.
y - 2 + 2 = x - 1 + 2
y = x + 1
Once again the 1 slope is implied. So these are both acceptable forms. I hope this helps!
The total number of leaves that was collected by Lisa is the product of the number of days in a week and the number of leaves she collected per tree. This is shown below, (7 trees / week) x (7 leaves / 1 tree) = 49 leaves / weekThus, Lisa collected 49 leaves in a week.
