They collected 300 cans in all. I did this by multipying 63 by 100 (6300) then divided it by 21. I hope this helps!
Answer:
40 pounds
Step-by-step explanation:
Given: Cost of a candy
=
per pound
Cost of candy 
Total amount of mixture of be produced = 
Selling price of mixture = 
Let´s x be the amount of
to be mixed in the mixture.
∴ Cost of
in the mixture = 12x
Next, Cost of
in the mixture = 
And we know the cost of final mixture = 
Now, putting all the value in the equation
⇒ 
⇒ 
⇒ 
∴ 
∴ 40 pounds of candy worth $12 per pound to be mixed in the mixture.
Answer:
cot(θ)=5/12
Step-by-step explanation:
(I'm going to replace theta with x to save time.)
Recall that sine is equal to opposite over hypotenuse. Thus:
sin(x)=12/13, this means that the opposite side is 12 while the hypotenuse is 13 (well, it doesn't have to be, but their ratios are).
Find the adjacent side using the Pythagorean Theorem.
13^2 = 12^2 + adj^2
adj^2 = 25
adj = 5.
Recall that tan(x) is opposite over adjacent. This means that cot(x) is adjacent is opposite.
Therefore: cot(x) = 5/12.
Answer:
d-{1,6}
Step-by-step explanation:
See the picture section.
The size of the dolphin would be 13.5 inches long because half of 27 is 13.5.
27/2 = 13.5
