Answer:
Step-by-step explanation:
If OA is perpendicular to OC, then <OAC = 90°
<OAC = <AOB + <BOC
Given
<AOB = 6x-12
<BOC = 3x+30
On substituting this values into the formula:
6x-12+3x+30 = 90
9x+18 = 90
Subtract 18 from both sides
9x+18-18 = 90-18
9x = 72
x = 72/9
x = 8°
Since <AOB = 6x-12
<AOB = 6(8)-12
<AOB = 48-12
<AOB = 36°
Also <BOC = 3x+30
<BOC = 3(8)+30
<BOC = 24+30
<BOC = 54°

Answer:
1 bat : 0 hits
Step-by-step explanation:
To get this unit rate all you have to do is divide both sides by 4.
(4/4) : (0/4) = 1:0
We get the same number of hits as in the original problem because 0 divided by any number (other than 0) will always equal 0.
