Answer:
Step-by-step explanation:
We have been given that Courtney had 15 hits in 60 at bats.
We know that batting average can be determined by dividing hits by number of at-bats.
Therefore, Courtney's batting average is 0.25.
We are already told that Katie's average was 0.300. Therefore, Katie's batting average is 0.300.
We have been given that Sara got a hit 32.5% of the time. To find Sara's batting average, we need to convert 32.5% into decimal as:
Therefore, Sara's batting average is 0.325.
Let the money spent by John = y
and Amy=x
ATQ
x+y = $29
It is given that jon spend 5 more than Amy. SO he spend
x +5
x+y = $29
x+x+5=$29
2x = 29-5
2x= 24
x = 24/2 =12
So Amy spend $ 12 and Jon spend x+5 = 12+5 = $17
Answer:
84°
Step-by-step explanation:
Solve for n. Note that the angle measurements of a circle will equal 360°. Set all the angles = 360°.
7n + 12 + 13n - 16 + 6n = 360
Combine like terms:
(7n + 13n + 6n) + (12 - 16) = 360
26n - 4 = 360
Isolate the variable, n. Note the equal sign, what you do to one side, you do to the other. First, add 4 to both sides:
26n -4 (+4) = 360 (+4)
26n = 360 + 4
26n = 364
Next, divide 26 from both sides:
(26n)/26 = (364)/26
n = 364/26
n = 14
Next, plug in 14 for n in the angle measurement, 6n:
6n = 6(14) = 84°
Note that these are central angles, which means that the arc's will be the same measurement as the angle's measurement.
arcBC = 84°
84° is your answer.

X = -14
x+10-5=-9
x+5=-9
