The mode is the number that appears most often. In this case, the mode is 100.

Subtract 10 from both sides (6x + 10 - 10 = 40 - 10) This means that 6x = 30 Divide both sides by 6 (6x/6 = 30/6) This means x = 5

Since this is an equilateral triangle, all sides measure 5cm.
Perimeter = side+side+side
5+5+5=15

Area = base x height, but something must be cut in half (divided by 2).
The simplest thing to do here is to cut the base (10) in half, so:
5 x 7 = 35

One gallon = 16 cups, so 16 gallons = 16 x 16 cups, or 256 cups.

Some triangles have no equal sides. These are called "scalene" triangles. All of the other statements are true.

To find her average, add the test scores and divide by five (because there were five scores). This comes to 91.6, which rounds up to 92.

Multiply the cost of the television by the tax (written as a decimal): 536 x .08 = 42.88 Add 42.88 back to the price of the television: 536 + 42.88 = 578.88

a squared + b squared = c squared, so...
12 squared (144) + 14 squared (196) = c squared
144 + 196 = c squared
340 = c squared, so the square root of 340 = c
c = 18.4

The radius is always half of the diameter, and the diameter is always twice the radius.
