Let us for a few seconds nevermind there's a circle at all, so we only really have a triangle by itself.
now, EF = 18, wait a second! EF is the base of the triangle, and h = 10.725, wait a minute!! "h" is the height of the triangle.
so, what's the area of a triangle whose base is 18 and has a height of 10.725? yeap, we knew you'd know that one.
what's the length of the arcEF? well, we know the central angle of ∡FOE is 80°, well, arc's get their angle measurement from the central angle they're in, so if ∡FOE is 80°, so is arcEF then.
4.a)2x+10 >27
4.b) 27-10= 17
17/2=8.5
3.a) 40-2x>7
3.b) 7-40=-33
-33/-2=16.5
So 16 students in her class
Answer:
D
Step-by-step explanation:
We can see in the graph f(x) that the x intercept is 
.
In the table of g(x), we can see that the x intercept is 
.
Since 
, the x intercept of the graph f(x) is greater than the x intercept of graph g(x).
Answer:
If the mean of four numbers is 7, we know that their sum is 7 * 4 = 28. We can use this information to find the last number. If the fourth number is x, we can write:
2 + 5 + 17 + x = 28
24 + x = 28
x = 4
Answer:
Exact form: x=19/9
decimal form: x=2.1r
Mixed number form: x=2 1/9
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
