Last week michael practices shooting free throws for 2 hours longer than gen. together michael and gen practiced shooting free throws for 12 hours how many hours did they each practice last week?

Michael (m) practiced 7 hours and Gen (g) practiced 5

Step-by-step explanation:

g+m+2=12

      -2   -2

g+m=10

10 divided by 2 is 5

They both practiced free throws for 5 hours. Michael practiced two hours more that Gen. 5+2=7. Therefore, Michael (m) practiced 7 hours and Gen (g) practiced 5.

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!

is only a line? i think so
