Luba_88 [7]

Answer:

  4 killer whales

Step-by-step explanation:

The dimensional analysis is ...

  (whales/ft³)(ft³/tank) = whales/tank

Putting the numbers with the units, we get ...

  (1.1142·10^-5 whales/ft³)(3.5900667·10^5 ft³/tank) = 4.00005... whales/tank

The maximum number of killer whales allowed in the main show tank is 4.

A line goes through the point (-8,9), and has a slope of 3/4
olya-2409 [2.1K]

Answer:

y=\dfrac{3}{4}x+15

Step-by-step explanation:

Given that,

A line goes through the point (-8,9), and has a slope of 3/4.

We need to express in the form of Ax+B for this line.

We have, m = 3/4

So,

y=\dfrac{3}{4}x+B

Put y = 9 and x = -8 in the above equation.

9=\dfrac{3}{4}(-8)+B\\\\9=-6+B\\\\9+6=B\\\\B=15

So,

y=\dfrac{3}{4}x+15

It is the required equation of the line.
