Answer:
mp=sp+25%ofsp=1.25sp
mp=1.25sp
sp=1/1.25×mp=0.8mp
cp=mp-30%ofmp=0.7mp
discount=mp-sp=mp-0.8mp=0.2mp
- discount %=discount/mp×100%=0.2mp/mp×100%=20%
- profit=sp-cp=0.8mp-0.7mp=0.1mp
- profit%=profit/cp×100%=0.1mp/0.7mp×100%=0.1×100/0.7%=10/0.7%=14.28%

Examine the relationship between y and x, waiting until later to examine the y-intercept. For example: If we look at B, and mult. x = 2 by 0.55, we get 1.10, which is not even close to the y = 6.5 given in the table. If, however, we mult. 2 by 3.55, we get 7.10, which is not the same as the y = 6.5 given in the table, but is much closer than 1.10.
Also note that all y values in the table are positive, so a negative slope would be inappropriate. That eliminates choices A and D.
Focus now on the remaining choices B and C. Again, let x= 2 and determine the associated y value. Which y value is closer to the table's 6.5?
B: 0.55(2) + 3.55 = 4.65 (relatively far away from the table's 6.5)
C: 3.55(2) - 0.55 = 6.55 (very close to the table's 6.5)
C is the correct answer.

If there is 6 people more in choir all you have to do is take the number that you already have (54) and times it by how many people you would have in choir (6)
Answer:
x = 25
Step-by-step explanation:
Correct question
In a right triangle Sin (40-x)=cos(3x) what is the value of x
Since Sin theta = Cos(90-theta)
Sin (40-x) = Sin(90-3x)
40 - x = 90 - 3x
-x+3x = 90 - 40
2x = 50
x = 25
Hence the value of x is 25
