Since it's an ordinary deck, there are 52 cards in the deck. Assume the deck is fair.
Winning cards are spades and there 13 of those in the deck - the numbers 2 through 10 (9 if them), the three face cards (J, Q, K), and the A.
Winning cards are also aces are there four of them - one for each suit (Hearts, clubs, diamonds, spades)
However the Ace of spades is among both groups so we remove it from the last group to avoid double counting. (You could from the first, but the subtraction is a must)
So there are 13 + 4 - 1 = 16 winning cards out of the deck of 52.
Thus our probability is 16/52.
n² = -35 - 12n
Add 12n and 35 to both sides
n² + 12n + 35 = 0
Find the factors of 35 that add or subtract to positive 12:
Factors of 35: 1, 5, 7, 35
5 and 7 add up to 12
n² + 12n + 35 = 0
Instead of 12n, you can replace it with 7n + 5n because they add up to 12n
n² + 7n + 5n + 35
Factor the equation separately
n(n + 7) + 5(n + 7)
Now factor out the (n + 7)
(n + 7)(n + 5)
B= 20°
and c = 160°
b is equal to the given angle, b = 20°
c is 180 - 20 = 160°
If one serving of granola provides 4% of your daily protein, that means you need the another 96% of protein (which in this case is 48g)
x=48/0.96 (using x as daily protein)
x = 50
Therefore you need 50 grams of protein daily
Corresponding angles are 3 and 7, 4 and 8, and 2 and 6.
