Answer:
? = 12
Step-by-step explanation:
Find the average of the 2 end values, that is
? = 
= 
= 12
The quadratic formula is shown below:
x = (-b±√(b^2-4ac))/2a
You have the equation 3x^2+5x+2 = 0; so "a", "b" and "c" are:
a = 3
b = 5
c = 2
When you substitute a=3, b=5 and c=2 in the Quadratic Formula, you get two roots:
x = (-5±√1)/6
x1 = (-5+1)/6 = -2/3
x2 = (-5-1)/6 = -1
The correct answer is "B":
x = -2/3, -1
Well if they are complementary, they add up to be 90 degrees. If one angle is 51 degree, the other is the difference of 90 and 51. 90 - 51 is 49, so angle b is 49 degrees.
Answer:
The answers are:
Question 23: 140
Question 24: 25
Step-by-step explanation:
Question 23:
Since 25% is 1/4 of the <em>total amount of members</em> in the club, we need to <em>multiply</em> the amount of drum player (35), by 4.
35 x 4 = 140
Question 24:
The absolute value of -25 is 25, since the absolute value is the value without any signs.
Therefore, the answers are:
Question 23: 140
Question 24: 25
