The ratio of cats to all animals is 12:23.
Use the law of cosines:
c² = 8² + 11² - 2•8•11 cos(37°)
c² ≈ 44.4402
c ≈ 6.66634
Answer:
Discount:
$2.85
final price
$54.15
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 57 × 5/100
Discount = 57 x 0.05
You save = $2.85
Final Price = Original Price - Discount
Final Price = 57 - 2.85
Final Price = $54.15
To factor you have to do this:
s^2 + 9s = -20
+ 20 +20
s^2 + 9s + 20 = 0
now you need to numbers that multiplied give you 20
and then those same 2 numbers have to add to 9
5 x 4 = 20
5+ 4 = 9
(x + 4) (x+ 5)
that means that x= -4, and -5
