It takes them 45 minutes if they start at the same time, but adding them together it would be an hour.

So 1/4 of an hour is 15 minutes so we have Tracy's time
and to find Trent's you multiply 15 by 3 and you get 45
so you add 15 by 45 it would be an hour (Or 60 minutes)

You earn $15 per lawn. 1 lawn would be $15. 15(1) is 15.
7 lawns would be 15(7), which is 105.

Hello!

You use the Pythagorean theorem to solve this

a^{2} + b^{2} = c^{2}

Put in the values it tells you to

a^{2} + 4.4^{2} = 5.5^{2}

Square the numbers

a^{2} + 19.36 = 30.25

Subtract 19.36 from both sides

a^{2} = 10.89

Take the square root of both sides

a = 3.3

The answer is 3.3

Hope this helps!

Step-by-step explanation:

Side a = 63

Side b = 21

Side c = 66.40783 = 21√10

Angle ∠A = 71.565° = 71°33'54" = 1.24905 rad

Angle ∠B = 18.435° = 18°26'6" = 0.32175 rad

Angle ∠C = 90° = 1.5708 rad = π/2Area = 661.5

Perimeter p = 150.40783

Semiperimeter s = 75.20392

Height ha = 21  

Height hb = 63

Height hc = 19.92235

Median ma = 37.85829  

Median mb = 63.86901

Median mc = 33.20392

Inradius r = 8.79608  

Circumradius R = 33.20392  

Vertex coordinates: A[0, 0] B[66.40783, 0] C[6.64078, 19.92235]

Centroid: [24.34954, 6.64078]

Inscribed Circle Center: [12.20392, 8.79608]

Circumscribed Circle Center: [33.20392, 0]
