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.

Answer:
1872 gross should Reggie order for a three month supply.
Step-by-step explanation:
Given:
200 guitar picks each week.
To Find:
How many gross should be ordered for three months period
Solution:
Now the guitar picks corresponds to the order picks by gross as follows;
given that 200 guitar picks corresponds to 144 gross orders
Now 200 are sold for each weeks i.e 7 days
<em>Now for 3 months there are approximately 13 weeks </em>
so Total sell for 3 months=13*200=2600 guitars
Now The ratio of guitar picks to gross orders is ,
144/200
=1/1.39=0.72
So 2600 guitars corresponds to 2600*(1/1.39)
i.e. 2600/1.39
=1872 Gross orders are required to get three month of supply
Answer:
Step-by-step explanation:
You can look at it and see that 1/3 is added to each term. The common difference is 1/3. If you want to be be more formal,
d = d4 - d3
d = 0 - - 1/3
d = 0 + 1/3
d = 1/3
Ummm 48 cm ima be honest I need some points my fault
Answer:
The number of butterflies he collects = 176
The number of moth he collects = 44
Step-by-step explanation:
This question has to do with ratio.
We are told in the question that:He collects 4 butterflies for every moth.
Hence, the ratio of
Butterflies : Moth
4 : 1
Sum of the proportion = 4 + 1 = 5
We are also told he has a total of 220 butterflies and moths.
Hence:
The number of butterflies he collects is calculated as
4/5 × 220 = 176 butterflies
The number of moth that he collects =
1/5 × 220 = 44 moth
