I don't get it.

Answer=65° & 130°
195°=angle1+angle2
195°=(11+4x)+2(11+4x)
195°=33+12x
subtract 33 for both sides
162=12x
13.5=x
Now lets solve for the measure of the angles
angle1=11+4x
angle1=11+4(13.5)
angle1=11+54
angle1=65°
angle2=2(11+4x)
angle2=2(11+4(33.5))
angle2=2(11+54)
angle2=2(65)
angle2=130°
Answer:
The profit margin for the concert sponsorship is 31.3725 %
Step-by-step explanation:
An arena receives for 1 event = $1700
An arena receives for 12 events =
An arena receives for 12 events = 20400
The costs for this sponsorship total $14,000
Profit = 20400-14000
Profit =6400
Profit margin =
Profit margin =
Hence the profit margin for the concert sponsorship is 31.3725 %
Answer:
1. IQ range
2. Frequency
3. Mean
4. Standard deviation and variance
Step-by-step explanation:
To use statistics the researcher must determine the standard deviation, mean and variance. He will need the following to calculate the mean:
1. The IQ score range and the frequency of the range.
To calculate the standard deviation and mean:
1. Need the mean and frequency of the IQ scores
Therefore the 4 things needed is:
1. IQ range
2. Frequency
3. Mean
4. Standard deviation and variance
Answer:
(x − 6i) (x + 6i)
Step-by-step explanation:
Using real numbers, x² + 36 is already simplified.
Using imaginary numbers:
x² + 36
x² − 36i²
(x − 6i) (x + 6i)
