Marie's pet turtle, Speedy, is getting too big for his tank! So, Marie bought a new tank shaped like a rectangular prism. The new tank is 2 feet long, 1 foot wide, and 11 feet high.
What is the volume of the tank?
Write your answer as a whole number, proper fraction, or mixed number.

Volume = 3¾ ft³

Step-by-step explanation:

Volume of the tank = Volume of a rectangular prism

= Length*Width*Height

Volume = 2½ × 1 × 1½

Convert to improper fraction

Volume = ⁵/2 × 1 × ³/2

Volume = (5 × 1 × 3) / (2 × 2)

Volume = 15/4

Volume = 3¾ ft³

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
