Cosine of B equals a divided by c
Answer:
Its a loss.
Step-by-step explanation:
This is because when you buy something for $20 and sell it for 35$ you lose money. After buying and selling youʻre only left with $15 which is less than the $20 you had in the first place.
You were given the data as statistics so that you can predict the number of a certain type of fish through ratio and proportion. The main focus here is then number of bluegill fish. From the given statistics, the number is 87. The total number of fishes at that time was 52+61+87 = 200. So, assuming that this composition is uniform in the said lake. We can then use the ratio from the given statistics to know the proportion of bluegills to the total fishes. Hence, we equate the two ratios:
87/200 = x/800
where x is the number of bluegills among the 800 total fishes that is in proportion to the gathered statistics. Solving for x, we determine the answer to be
x = 348

Answer:
x = 12
Step-by-step explanation:
Given x varies as the cube root of y then the equation relating them is
x = k![\sqrt[3]{y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7By%7D)
← k is the constant of variation
To find k use the condition x = 6 when y = 8, thus
k = ![\frac{x}{\sqrt[3]{y} }](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B%5Csqrt%5B3%5D%7By%7D%20%7D)
= ![\frac{6}{\sqrt[3]{8} }](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B%5Csqrt%5B3%5D%7B8%7D%20%7D)
= 
= 3
x = 3 ← equation of variation
When y = 64, then
x = 3 × ![\sqrt[3]{64}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D)
= 3 × 4 = 12
