The amount Troy charges to mow a lawn is proportional to the time it takes him to mow the lawn. Troy charges $30 to mow a lawn t

Inessa05 [86]

Answer:

D = 20H

Step-by-step explanation:

The amount Troy (D, in dollars) charges to mow a lawn is proportional to the time (H, in hours) it takes him to mow the lawn.

Hence, we can write D = kH ......... (1), where k is a constant.

Now, given that Troy charges $30 to mow a lawn that took him 1.5 hours to mow.

So, from equation (1) we get

30 = 1.5k

⇒ k = 20.

Therefore, equation (1) becomes D = 20H (Answer)

Please click the photo and there are two questions to solve .Please help me guys

madreJ [45]

Answer:

Step-by-step explanation:

Distance formula:

$\sqrt{(X_2-X_1)^2+(Y_2-Y_1)^2}$

Distance for AB

$\sqrt{(4-2)^2+(1-(-5))^2}=\sqrt{4+36}=\sqrt{40}\\$

Distance for AC

$\sqrt{(8-2)^2+(-3-(-5))^2}=\sqrt{36+4}=\sqrt{40}$

same formula solve when positive

$5=\sqrt{(6-3)^2+(y-2)^2}\\25=9+(y-2)^2\\16=(y-2)^2\\4=y-2\\6=y$

Now when it's negative

$5=\sqrt{(6-3)^2+(y-2)^2}\\25=9+(y-2)^2\\16=(y-2)^2\\-4=y-2\\y=-2$

so y can equal 6 or -2
