Hourly rate:
39(1.3r) = 541.80
(hours times hourly rate equals profit)
then solve
1.3r = 13.89
r = 10.69
the hourly rate is $10.69
to answer the bottom question, 390 + 117 = 507, but that’s not close to 541.80 so I have no idea what they’re asking there
Answer:
2 and 3
Step-by-step explanation:
2) If two polygons are similar, the ratio of their areas is equal to the square of the ratio of their corresponding sides.
side ratio: 1/4------- area ratio: 1²/4² = 1/16 = 1:16 ratio
3)If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths.
The ratio of the perimeters is the same as the scale factor.
scale 1:4
Answer:
The mean tells us soccer players spend more time outdoors overall. The data set for soccer players shows that they have equal amount of variability when compared to the data set for basketball players.
Step-by-step explanation:
The average, the mean, for soccer players is greater, so they spend more time outdoors overall. The range, however, is the same, so they have an equal amount of variability.
(–1, 4) to (–4, 1) and <span>(4, 1) to </span><span>(–1, –4)
so
The rule is (x,y) --> (-y,-x)
The reflection over y = - x
hope it helps
