Answer:
x + y = 20
Step-by-step explanation:
Let the amount collected by Alexa = $x
& the amount collected by Daniel = $y
Total amount collected = $20
Therefore,
x + y = 20
First, find the arc measure BD. The arc measure is twice the central angle measure. BD should be 48*2 = 96.
The chord BC looks like it’s the diameter of the circle, so it must have a measure of 180.
From here you can find DC. The total measure of a circle is 360.
360- 96-180 = 84, so DC is 84.
DBC is 360- DC
so 360- 84 = 276.
DCB is just 360- BD
so 360- 96 = 264.

Even numbers are divisible by 2 with no remainder. 13/2 = 6.5 so yes.
Answer:
88.8%
Step-by-step explanation:
1.) 30-18= 12 which is the number of member that had an average of 84
2.)Then multiply 12 times 84 = 1008
3.) You multiply 18 by 92 which equals 1656
4.)Add 1008 and 1656 together and get 2664.
5.)Divide 2664 / 30 and you get the average of 88.8
