EASY BRAINLESS... seventy percent of the fish in an aquarium are salmon. if there are a total of 450 fish in the aquarium, how many salmon are there? how many fish are not salmon​

there are 135 fish that are not salmon and 315 that are.

Step-by-step explanation:

There are 315 salmon and 135 fish that aren't salmon.

Step-by-step explanation:

The number of salmon in the aquarium would be 70% of the 450 fish, so to find the number you multiply .7 by 450:

450 × .7 = 315

So, there are 315 salmon. To find how many fish are not salmon, you would subtract 315 from 450:

450 - 315 = 135

So, 135 of the fish are not salmon.

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
