Answer:
The jar contains 132 grams of zinc
Step-by-step explanation:
zinc to copper = 3 : 19
New equivalent weights
zinc to copper = x : 836
Now, let us solve for x as follows

the jar contains 132 grams of zinc
To check if the answer is accurate, the answer gotten when the weight of zinc is divided by copper will be the same for both the old and new ratios:
old ratio: 3 ÷ 19 = 0.158
new ratio: 132 ÷ 836 = 0.158

Answer:
2.1
Step-by-step explanation:
By the Law of Cosines,
a² = 5² + 6² - 2(5)(6)cos(20°)
a = sqrt(5² + 6² - 2(5)(6)cos(20°)), which is about 2.1
The answer is A.
First, you change the degrees to radians.
133(pi/180)= 2.3212879051524583373085087220899 (long number)
Then you just plug that into the formula!
(r^2*theta)/2
(13.9^2 * 2.3212879051524583373085087220899) / 2 = 224.24801807725323767568848509749
