Factor rainbow: you can use a factor rainbow whether a list of factors is correct. to create a factor rainbow, list the factors of a number in order from least to greatest. then draw arches that link the factor pairs. for perfect squares, there is no connecting arch in the middle. so, just circle the middle number. a factor for 12 is shown. create factor rainbows for 6, 24, 36 and 48.

The center of the circumscribed circle lies on line segment and the longest side of the triangle is equal to the of the circle.

The sat and act tests use very different grading scales. the sat math scores follow a normal distribution with mean 518 and standard deviation of 118. the act math scores follow a normal distribution with mean 20.7 and standard deviation of 5. suppose regan scores a 754 on the math portion of the sat. how much would her sister veronica need to score on the math portion of the act to meet or beat regan's score?

Maria found the least common multiple of 6 and 15. her work is shown below. multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, . . multiples of 15: 15, 30, 45, 60, . . the least common multiple is 60. what is maria's error?
