To do this you need the mean.
(81*9+70)/10 that is the mean equation.
Solve.
(799)/10
79.9
79.9% Will be your grade or a C
given:
x² + 12x = 11
perfect square:
a² + 2ab + b²
a² = x² ⇒ x * x
2ab = 12x ⇒ 2(6)x
b² = 6² ⇒ 36
x² + 12x + 36 = 11 + 36
(x+6)(x+6) = 47
Both sides must be added with 36.
It’s A
Cuz 16 \ by 2 is 8 and 36/ by 2 is 18
Answer:
2.406%
Step-by-step explanation:
28600*18%=5148
$5148-28600=$23,452

if there is only 6 boys that means there are 14-6=8 girls
so the ratio of girls to boys is 8:6
know when it says all students we have to include girls too
so in a class of 14 there are 6 boys and 8 girls
14:8 is our answer
