You can add the exponents of x^3*x^4 instead of writing it all out. Do you would just have to add 3+4 since the variable (x) is the same. And you would get x^7
Conner: $354 - 243 cents
243 cents = $2.43 because 100 cents = 1 dollar
Conner: $354 - $2.43 = $351.57
$351.57
He has 351 dollars left.
The water should fill the aquarium to 1.5 feet
Solution:
Given that the directions for the aquarium say that it should be filled with 9 cubic feet of water.
This means volume of aquarium is 9 cubic feet
Given that aquarium is 2 feet wide and 3 feet long
To find: Height of aquarium
Since a aquarium is in shape of cuboid, we can use the volume of cuboid formula
<em><u>The volume of cuboid is given as:</u></em>
volume of cuboid = 
Where "l" is the length
w is the width
"h" is the height
Substituting the values, we get,

Thus the height of aquarium is 1.5 feet
Volume for a cone is 1/3 pi * r^2*h, where r is radius and h is height.
We have diameter = 1/2 radius. Thus, radius = 1.5in. We also have volume is 12 in.
Using formula for volume of a cone and plugging in what we know, we have
12 = 1/3*pi*(1.5)^2*h, were solving for h.
To get, h= (12*3)/(pi*(1.5)^2), which is approximately 5.0931in, 5 inches
The answer is A because if you look at the other points you can see a pattern that they are opposites so A is you answer <span />
