Line segment CD is shown on a coordinate grid: The line segment is reflected about the y-axis to form C′D′. Which statement describes C′D′? (4 points) C′D′ is perpendicular to CD. C′D′ is half the length of CD. C′D′ is greater than twice the length of CD. C′D′ and CD are equal in length.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
