219+159≤x≤369+309
The answer can then be simplified to
378≤x≤678
Answer:
d
Step-by-step explanation:
in order for it to be a triangle the angles have to add up to equal 180
5+75+100=180 so its not a
10+80+90=180 so its not b
20+60+100=180 so its not c
45+45+45=135 so its d because the angles dont add up to 180
50+50+80=180 so its not e
1. The surface that will be exposed to the rain is the lateral surface of the cylinder and the hemisphere.
2. The lateral area of the cylinder is a rectangle with height equal to the height of the cylinder and width equal to the circumference of the base of the cylinder.
3. the circumference of the base = 2

r=2*

*5=10

so the lateral area = 10

*h=10

*40=400

(

)
4. The surface area of a sphere is

so the surface of the hemisphere =

(

)
5. Total area exposed = 450
Answer:
its b. cuz got the friggen question wrong when i did it. >:(
Hey,
Depends on what you want us to do with the equation.
If you want us to simplify the expression, here you go:

.
Let me know if this isn't what you need, and I'll try to help the best I can.
