A pet store has three fish tanks, each holding a different volume of water and a different number of fish. Tank AAA holds 40\tex
bearhunter [10]

Answer:

C, A and B

Step-by-step explanation:

Tank A holds 40 Liters and 5 fish.

  • Volume per fish of Tank A =40 \div 5 =$ 8 fish per liter

Tank B holds 100 Liters and 12 fish.

  • Volume per fish of Tank B =100 \div 12 =$ 8.33 fish per liter

Tank C holds 180 Liters and 23 fish.

  • Volume per fish of Tank C =180 \div 23 =$ 7.83 fish per liter

Therefore, the volume per fish from least to greatest is:

7.83, 8 and 8.33

These correspond to the tanks: C, A and B respectively.

What two numbers multiply to -8 and add to -4
Ronch [10]

Answer:

  -2-2√3, -2+2√3

Step-by-step explanation:

Let x represent one of the numbers. Then the other number is -4-x. We want the product to be -8:

  x(-4-x) = -8

  -4x -x^2 = -8 . . . . . eliminate parentheses

  x^2 +4x = 8 . . . . . . multiply by -1

  x^2 +4x +4 = 12 . . . add 4 to complete the square

  (x +2)^2 = 12

  x +2 = ±√12 = ±2√3

  x = -2±2√3

The two numbers are -2-2√3 ≈ -5.4641, and -2+2√3 ≈ 1.4641.

The solution set to 6 + 2n > 12 is n > 3. Which are correct representations of this solution? Select two options.
s344n2d4d5 [400]

The correct representations of this solution are

  • (d) A number line going from negative 5 to positive 5. An open circle appears at positive 3. The number line is shaded from positive 3 to negative 5.
  • (e) (3, ∞)

<h3>How to determine the solution set?</h3>

The inequality is given as:

6 + 2n > 12

The solution is given as:

n > 3

When the above inequality is represented as an interval, we have:

(3, ∞)

Also, the inequality symbol > is represented using an open circle.

This means that the number line would use an open circle and the arrow would point right

Hence, the correct representations of this solution are (d) and (e)
