Write and solve an equation of ratios:
12 x
----- = -----------
17 $289
Cross multiplying results in 17x = 3460, or x = $3460/17 = $204.
Jenny would make $204 for 12 hours of work.
I believe the equation shown above is an example of:
B. Associative Property of Addition.
Hope I helped!!
Apply the Pythagorean Theorem here.
Square the lengths of the 2 shorter sides: (20 mi)^2 and (40 mi)^2. Correct results are 400 and 1600. Combine these: obtain 2000.
Then the length of the diagonal (which is the distance between the 2 cities) is
sqrt(2000) = sqrt(400)*sqrt(5) = 20 sqrt(5) (answer)
