Answer:

1229 km

Step-by-step explanation:

The missing angle is ...

180° -60° -75° = 45°

Knowing that, the Law of Sines can be used to find the side opposite the 75° angle.

?/sin(75°) = 900 km/sin(45°)

? = (900 km)sin(75°)/sin(45°) ≈ 1229.423 km

The UFO is about 1229 km from KA-12.

Jenna can clean the gutters at her house in four hours. Her older brother, John, can clean the gutters in three hours, if they w

OlgaM077 [116]

Answer:

1 hour and 42.8 minutes

Step-by-step explanation:

To answer this question let's call $t_1$ while it takes Jenna to clean the gutters

Let's call $t_2$ while it takes John to clean the gutters

$t_1 = 4$ h

$t_2 = 3$ h

t = total time

g = job = 1 (clean the gutters)

The speed of each one is:

$V_1 = \frac{1}{4}$ g/ h

$V_2 = \frac{1}{3}$ g/h

$V = V_1 + V_2 = \frac{g}{t} = \frac{1}{t}$

So:

$V = V_1 + V_2 = \frac{1}{4} +\frac{1}{3}$

$\frac{1}{t} = \frac{1}{4} + \frac{1}{3}= \frac{7}{12} g/h$

$t = \frac{12}{7}$ h

Then, both together paint $\frac{7}{12}$ of gutters for each hour.

This means that it takes $\frac{12}{7}$ hours to clean the gutters together

Finally cleaning together takes 1,714 hours or also

1 hour and 42.8 minutes
