Answer: 9 energy drinks and 18 granola bars.
Step-by-step explanation:
Price per granola bar = $0.50
Price per energy drink = $2.
We can define G as the number of granola bars that she bought, and D as the number of drinks that she bought.
Then
"She buys twice as many granola bars as energy drinks."
G = 2*D
" If she spends $27 in total"
G*$0.50 + D*$2 = $27
So we have a system of equations:
G = 2*D
G*$0.50 + D*$2 = $27
The first step will be to replace the first equation into the second one, and solve it for D.
(2D)*$0.50 + D*$2 = $27
D*(2*$0.50) + D*$2 = $27
D*$1 + D*$2 = $27
D*$3 = $27
D = $27/$3 = 9.
So she bought 9 energy drinks, and we know that:
G = 2*D
G = 2*9 = 18
She bought 18 granola bars.

Answer: 89.5 degrees
Step-by-step explanation:
Arctan (16/7)
Since all angles in a triangle are equal to 180 and you already have two angles you just have to subtract.
So, 180-(65 + 45)
Simplify = 180- 110
Equals = 70
Answer:
73920
Step-by-step explanation:
Number of ways to choose 9 appetizers from 12: ₁₂C₉
Number of ways to choose 3 main courses from 8: ₈C₃
Number of ways to choose 2 desserts from 4: ₄C₂
The total number of ways is:
₁₂C₉ × ₈C₃ × ₄C₂
= 220 × 56 × 6
= 73920
