Answer:
60° and 30°
Step-by-step explanation:
I'm going to assume you mean complementary angles.
Complementary angles are angles that form 90° or a right angle
From the question, it is saying that
(5x) +(4x-18) = 90
To work out x, solve the equation
9x-18 = 90
9x = 108
x = 12
Therefore the angle of 5x is 5x12 or 60° and the angle of (4x-18) is going to be 4x12-18 = 30°
To find how many cupcakes Ling must sell to break even, you will create an equation where the functions are equal.
0.25x + 30 = 1x; then solve the equation for x, the number of cupcakes.
0.25x + 30 = 1x
-0.25x -0.25x
<u>30</u> = <u>0.75x</u>
30 30
x = 40
Ling will need to sell 40 cupcakes.

Answer:
b) 9 in
Step-by-step explanation:
To find median arrange the data in ascending order and count the number of data's. if the total number of data is odd number, then (n/2)th term is the median.
If the total number of data is even, then Average of (n/2)th term and (n/2)+1 th term is the median
Ascending order:
6, 8, 8 , 8 , 9 , 9 , 10 , 11 , 12 , 16
total = 10. so even number
Median = average of 5th term and 6th term
=(9+9)/2
= 18/2
= 9
