Dave measures his calculator using erasers and paperclips. It is about 2 erasers long. Which is true?

Step-by-step explanation:

In the US, the most common eraser that is sold are the regular Pink Press erasers. These, as shown in the image below, are roughly 2.2 inches long. The most commonly used paper clip size is about 1.375 inches long. Assuming that these are the items that Dave is using to measure, then we can calculate the size of the calculator which is 2 erasers long...

2.2 + 2.2 = 4.4 inches long

The calculator is roughly 4.4 inches long, we can also divide this number by the length of the paper clip to find out how many paper clips make up the calculators length

4.4 / 1.375 = 3.2 paper clips

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512
