What is the best estimate for the length of a baseball bat?

42 inches

By regulation it may be no more than 2.75 inches (7.0 cm) in diameter at the thickest part and no more than 42 inches (1.067 m) in length.

Step-by-step explanation:

baseball bat - is a smooth wooden or metal club used in the sport of baseball to hit the ball after it is thrown by the pitcher.

length- a measure of distance.

30 inches

Step-by-step explanation:

STEP-BY-STEP SOLUTION:

~ Question No. 11 ~

To find x -

Corresponding angles are equivalent to each other.

There are corresponding angles in this problem. We can identify this through the 'F' shape which the angles form as well as that it is on paralell lines.

Therefore:

3x + 49 = 7x - 23

3x - 7x = - 23 - 49

- 4x = - 72

x = - 72 / - 4

x = 72 / 4

x = 18

To find y -

There are more corresponding angles in this problem. We can identify this through the 'F' shape which the angles form as well as that it is on paralell lines.

Therefore:

x = 18

3x = 11y - 1

11y - 1 = 3x

11y - 1 = 3 ( 18 )

11y - 1 = 54

11y = 54 + 1

11y = 55

y = 55 / 11

y = 5

FINAL ANSWER:

Hence, the answer is:

x = 18

y = 5

~ Question No. 12 ~

To find x -

Alternate angles are equivalent to each other.

There are alternate angles in this problem. We can identify this through the 'Z' shape which the angles form as well as that it is on paralell lines.

Therefore:

5x - 38 = 3x - 4

5x - 3x = - 4 + 38

2x = 34

x = 34 / 2

x = 17

To find y -

We will use the angle sum of a triangle to find y.

Angle sum of a triangle = 180°

Therefore:

x = 17

7y - 20 + 5x - 38 + 90 = 180

7y - 20 + 5 ( 17 ) - 38 + 90 = 180

7y = 180 + 20 - 5 ( 17 ) + 38 - 90

7y = 180 + 20 - 85 + 38 - 90

7y = 63

y = 63 / 7

y = 9

FINAL ANSWER:

Hence, the answer is:

x = 17

y = 9
