Mina is testing different types of heat lamps to determine which type is most effective for growing strawberry bushes. She purchases two different types of lamps from a local store. Mina applies brand A to one area of the yard and brand B to another area of the yard, both of which receive full sunlight. She waters the area with brand B daily; she waters the area with brand A every other day. At the end of the study, Mina concludes brand B is more effective in growing strawberry bushes. Is Mina's conclusion valid? Explain why or why not.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
