Answer: Choice D) 11
----------------------------
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(35) = 9/x
x*cos(35) = 9
x = 9/cos(35)
x = 10.9869712988531 ... make sure your calculator is in degree mode
x = 11 ... rounding to the nearest tenth
(x+1)•(5x-2) hope this helps
Answer: B
Step-by-step explanation:
The area of a circle is pi*radius^2. But only a diameter is given, so in order to find the radius, you must divide the diameter by 2:
3.6/2 = 1.8
Now, you can plug the radius, 1.8, into the equation pi*radius^2 (
):
= about 10.18
Lastly, you must divide the area 10.18 by 2 because you are looking for only half the area.
10.18/2 = 5.09
Answer:
Step-by-step explanation:
-2 = 17
You need find what number that need to be in the blank spot
17 + 2 = 19
19 - 2 = 17
In the second question u need to find equal number
17 - 3 = 16 - 2
14 14
They need to be equal - =
19 - 6 = 18 - 5
13 13
