Ariel weighed a mitten on her balance and recorded a mass of 2.3 grams. Her teacher told her that there was obviously something wrong with her balance because it was giving her a reading, which was actually 3 grams. What was the percent error of Ariel’s balance?

Answer:

23.33%

Step-by-step explanation:

Percent error = | E - A | /A * 100%

= | 2.3g - 3g | / 3g * 100%

= 23.33% error

(Read end and look at attached file for correct answers) Mrs. Ibarra wants to create a right triangle for a geometry test. She plans to use 15, 36, and 41 as side lengths. Which statements should she consider to determine whether it will be a right triangle? Check all that apply. 15 + 36 greater-than 41, so the side lengths will form a triangle. 15 + 36 not-equals 41, so those lengths will not form a triangle. 15 squared + 36 squared = 1,521 41 squared = 1,681 Since a squared + b squared not-equals c squared, it will not be a right triangle. 15 squared + 36 squared = 297 41 squared = 82. The correct answers are actually A, C, D, and E. I got it wrong because people said the answer were only A and C. And of course it was on a test so I couldn't fix it. Anyway i just want to prevent from anyone else being misled. Look at the attached file.
