80
Triangle’s interior angles total measure always equal 180.
40+60=100
180-100=80
Step-by-step explanation:
emily: 10(5/8) = 6 1/4 or 6.25 pounds left
10- 6.25 = 3.75 used
Frances : 10(2/5) = 4 pounds left
10-4 = 6 pounds used
Bills : 10(2/5) = 4 pounds left
10-4 = 6 pounds used
add them together
15.75 or 15 3/4 pounds of soil in the first flower bed

i dont know the answer hahahahhahahhahahahah
Answer:
x = 105 degrees.
Step-by-step explanation:
The small polygon is a regular hexagon so each internal angle = 120 degrees while the large polygon is a regular octagon with internal angle =
135 degrees.
So angle x = 360 - ( 120 + 135)
= 360 - 255
= 105 degrees.
Note we use the fomula T = 180( n - 2) to find total internal angles in an n sided polygon. So for hexagon T = 180(6-2) = 180*4 = 720 so each internal angle in a regular hexagon = 720/6 = 120 degrees.
For part A, we need to find the rate of change and initial values for Elliot's business. Because it states that Elliot started his business in 2000, we can use that for the initial value, meaning that on our graph, instead of starting at 2000, we can just start at 0. And for the rate of change, all we have to do is use the information given to set up the slope equation, which is (y2-y1)/(x2-x1). Because we know that the independent values usually go on the x-axis, we know that the years will be our x values, leaving the prices to be our y values. To set up the equation, we should have (1350-750)/(2010-2000), which should simplify to 600/10, which further simplifies to 60. This will be our slope!
