In baseball, a pitcher can throw a perfect game if he strikes out every player. If 3 strikes are 1 out and you need 3 outside in an inning, how many strikes does a pitcher need to throw in an entire game to throw a perfect game? (note: there are 9 innings total).

He would need to pitch 81 times

Step-by-step explanation:

3 x 3 = 9 this is one inning

9 x 9 =81

81 strikes

Step-by-step explanation:

First, lets figure out how many strikes for each inning. If you need 3 strikes for 1 out, and you need 3 outs per inning you would multiply 3 strikes by 3 outs to get 9 strikes for inning 1.

So, you now know that you need 9 strikes per inning, so lets take those 9 strikes per inning and multiply that by 9 innings total. 9x9=81.

You now know that a pitcher would need to throw 81 strikes to throw a perfect game.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
