An aquarium is to be drained. The aquarium is shaped like a rectangular prism with length 33 in , width 26 in , and height 12 in

artcher [175]

Answer:

To empty the aquarium it takes 26 minutes

Step-by-step explanation:

step 1

Find the volume of the aquarium

The volume of rectangular prism is

$V=LWH$

we have

$L=33\ in\\W=26\ in\\H=12\ in$

substitute the given values

$V=(33)(26)(12)=10,296\ in^3$

step 2

Divide the volume by the rate of 396 in^3 per minute

$10,296/(396)=26\ minutes$

therefore

To empty the aquarium it takes 26 minutes

(secA+cosA)(secA-cosA)=tan^2A+sin^2A

vlabodo [156]

$(\sec A+\cos A)(\sec A-\cos A)=\sec^2A-\cos^2A$

$\sec^2A-\cos^2A=(1+\tan^2A)-(1-\sin^2A)$

$(1+\tan^2A)-(1-\sin^2A)=\tan^2A+\sin^2A$

luda_lava [24]

Convert percent to decimal by moving the percent sign two places to the left.

12% => 0.12

'Of' in math means multiply: 0.12 * 30 = 3.6

3.6 is the answer.
