To find the unit rate you would need to find the cost per ounce of potato chips. To find this you would simply divide. $3.80/20 = .19
So the unit rate in your question is $0.19
Hope this helps! :)
Answer:
√(9/7)
Step-by-step explanation:
tan θ + cot θ = 7
Write tan and cot in terms of sin and cos.
(sin θ / cos θ) + (cos θ / sin θ) = 7
Multiply both sides by sin θ cos θ
sin² θ + cos² θ = 7 sin θ cos θ
Use Pythagorean identity.
1 = 7 sin θ cos θ
1/7 = sin θ cos θ
Remember that, we'll use it later. Go back to this step:
sin² θ + cos² θ = 7 sin θ cos θ
This time, add 2 sin θ cos θ to both sides.
sin² θ + 2 sin θ cos θ + cos² θ = 9 sin θ cos θ
Factor.
(sin θ + cos θ)² = 9 sin θ cos θ
Substitute.
(sin θ + cos θ)² = 9 / 7
Take square root.
sin θ + cos θ = √(9/7)
Option: rationalize the denominator.
sin θ + cos θ = 3√7 / 7
Answer:
D - ASA
This should be the answer since FH and IG can be said to be parallel and therefore we can find both alternate angles or a vertical opposite angle with one side given. We know that ΔFHJ is reduced by a factor of 2 to get ΔGIJ.
