Answer:
Ratio of blue fish in the small tank to the red fish in large tank is 10 : 6279
Step-by-step explanation:
Let the number of red fish and blue fish in the large tank are x and y respectively.
Similarly ratio of red fish and blue fish in the small tank are x' and y' respectively.
Since in each tank ratio of the red fish to blue fish is 333 : 444
That means x : y = 333 : 444
Or
⇒
⇒ y = --------(1)
Similarly x' : y' = 333 : 444
⇒
⇒
⇒ x' = ------(2)
Ratio of the fish in large tank to the fish in small tank is 464646 : 555
So (x + y) : (x' + y') = 464646 : 555
Now we replace the values of x and y' from equation (1) and equation (2)
Therefore, ratio of blue fish in the small tank to the red fish in large tank is 10 : 6279
Subtract 3 both sides first. R-3=ts²
next, divide both sides by t, (R-3)/t=s²
finally, take the square root of both sides
√(R-3)/t = s. 2nd choice.
Answer:
c
Step-by-step explanation:
1. We can asume that a = 2, b = 4. Then solve and find which option matches with the answer.
2. Equation itself plugged in with a = 2, and b = 4. 2^2 + 2 x 2 x 4 + 4^2 = 36 / (2 + 4)^3
3. 36 / 216 = 1/6
Find any option that matches your answer and plug in a for 2 and b for 4.
a. a + b = 2 + 4 = 6 - No doesn’t match 1/6
b. a^2 + b^2 = 2^2 + 4^2 = 4 + 16 = 20 - No doesn’t match 1/6
c. 1 / a + b = 1 / 2 + 4 = 1/6 - Yes does match 1/6
d. 1 / (a + b)^2 = 1 / (2 + 4)^2 = 1/36 - No doesn’t match 1/6
7 & 9 square's make 130.49+81=130.
