In (A) statistics class Wilson's students earn a higher ratio of a's to b's.

<h3>What are ratios?</h3>
  • A ratio in mathematics describes how many times one number contains another.
  • For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six.
  • Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.

To find the higher ratio:

Given -

  • Geometry class = a:b = 12:20 = 3:5
  • Statistics class = a:b = 11:15

As we can observe that 3:5 < 11:15.

Therefore, in (A) statistics class Wilson's students earn a higher ratio of a's to b's.

The equation that can be used to find the length of the tank is 240 = l × 12 × 10

<h3>How to find the volume of rectangular prism?</h3>

The volume of a rectangular prism can be found as follows:

volume of rectangular prism = lwh

where

  • l = length
  • w = width
  • h = height

Therefore,

volume of rectangular prism = lwh

volume of rectangular prism = 240 ft³

h = 12 ft

w = 10 ft

Therefore, the let's find the length of the tank.

240 = l × 12 × 10

240 = 120l

divide both sides by 120

l = 240 / 120

l = 2

Suppose that y varies inversely with x. Use the information to find k, and then choose the equation of variation. X= 2.5 when y=
puteri [66]

Answer:constant of variation(k) is, 250.

Step-by-step explanation:

The inverse variation says that:

then, the equation is in the form of :

       ....[1] where, k is the constant of variation

As per the statement:

Suppose that y varies inversely with x.

then,

by definition of inverse variation we have;

When x = 2.5 and y = 100 then

Substitute these in [1] we have;

Multiply 2.5 both sides we have;

or

k = 250

⇒

Therefore, the constant of variation is, 250 and the equation we get
