This is because two angles are zero and top is a straight line, and a line is 180 degrees!
hopes this helps :)
Let that certain number be 'n'
50% (n) = 39
50% ⇒ 0.5
0.5 (n) = 39
Divide both sides by 0.5
0.5n = 39
/0.5 /0.5
n = 78.
So that certain number is actually <em><u>78! :)</u></em>
CROSS CHECK:
50% of 78
0.5 × 78
= 39

A) there are 26 possible outcomes
B) 5/26 chances of picking a vowel
C) 21/26 chances of picking a consonant
P(x) = 2x² - 4xq(x) = x - 3
To find the answer, we plug q(x) into p(x):
p(q(x)) = 2(x - 3)² - 4(x - 3)p(q(x)) = 2(x² - 6x + 9) - 4x + 12p(q(x)) = 2x² - 12x + 18 - 4x + 12p(q(x)) = 2x² - 16x + 30
The third option is correct.
Answer:
150
Step-by-step explanation:
100% represents 500 jars
Subtract the sum of the percentage of other jars for percent of blue jars
100 - (30 + 25 + 15) = 100 - 70 = 30%
That is 30% of the jars are blue
Calculate 30% of 500 to obtain number of blue jars
30% = 
= 0.3, hence
number of blue jars = 0. 3 × 500 = 150
