We know that 70% of all comic book fans are male, and that 40% of Company A fans are male.
Since 25% of all comic book fans are company A fans:
0.4 * 0.25 (meaning 40% of 25%) = 0.1, or 10% of all comic book fans are male company A fans.
What percentage, then, of male comic book fans are company A fans?
0.1 ÷ 0.7 = 0.142
We divide 10%, the percentage of all comic book fans that are male and company A fans, by the percentage of comic book fans that are male, since we are given that the fan is male.
Answer is 0.14
Answer: 25 games
Step-by-step explanation:
Take the fractions 76/100 and 19/x
Cross multiply. 76 times x equally 76x and 100 times 19 equals 1900.
Divide 76x by 76 which equals just x.
Divide 1900 by 76 which equals 25.
x=25

Answer:
$51.48
Step-by-step explanation:
Percent left: 100%-67%=33%
33% can also be expressed as the fraction 33/100
Then, 33% of 156 is 156*33/100=51.48
Answer:
ax²+ bx + c = 0
Step-by-step explanation
Multiplying (x+4) and (x−1) together (called Expanding) gets x2 + 3x − 4 :
expand vs factor quadratic
So (x+4) and (x−1) are factors of x2 + 3x − 4
Just to be sure, let us check:
(x+4)(x−1) = x(x−1) + 4(x−1)
= x2 − x + 4x − 4
= x2 + 3x − 4 yes
Yes, (x+4) and (x−1) are definitely factors of x2 + 3x − 4
