Answer:
C. AB/EF = BC/EF
Step-by-step explanation:
If the triangles are similar then the ratio of these side lengths must be equal.
Answer:
Male Fish = 20
Female Fish = 16
Step-by-step explanation:
Let number of male fish be x and number of female fish be y
There are 36 fishes in total, so we can write:
x + y = 36
or
x = 36 - y
Also, male fish (x) cost 5 each and female fish (y) cost 7 each totalling $212, so we can write:
5x + 7y = 212
Now, we can put 1st equation in 2nd equation and get an equation in "y" and solve for y first:
We know x = 36 - y, so
x = 36 - 16
x = 20
Thus,
there are
20 Male fishes & 16 female fishes in the aquarium

Answer:
She can create a function for the total savings in terms of the time x by adding the two functions together. The new function should look like this:
T(x)=S(x)+a(x)
So now we can substitute the given functions:
T(x)=450+6(x-2)
But this function can be simplified for it to be easier for her to calculate her total amount of savings. We can do that by distributing the 6 into the parenthesis. This is, multiply the 6 by both the x and the -2, so we get:
T(x)=450+6x-12
and now we can combine like terms. We can subtract 12 from 450 so we get:
T(x)=6x+438
And that will be our final function.
