**Answer:**

∡1 = 64°

**Step-by-step explanation:**

∡3 = 180-104 which is 76°

∡1 = 180 - (40 + 76) = 180-116 or 64°

Answer:

1.2 hours

Step-by-step explanation:

John can do a job in 2 hours

Ben can do the same job in 6 hours

Let y represent the time it will take both men to do the job together

y/2 + y/6=1

5y/6= 1

Cross multiply

5y = 6

y= 6/5

y= 1.2

Hence it will take both of them 1.2 hours to finish the work together

A. 4/5

To find the slope, you need to isolate y.

4x-5y=-1

-5y= -1-4x (or -4x-1)

-y= (-4/-5)x-1/-5

y=4/5x+1/5

First take 18 and divide by 50 = .36, so your percent is 36%.

In this problem the mass of the asteroid is completely irrelevant. To solve this we are going to take advantage of the fact the 1AU=<span>149,598,000 kilometers, so we can establish a conversion factor as follows:

<span>

We can conclude that the asteroid is 413,937,666 kilometers away from the sun, or in scientific notation </span>4.139376660

<span>·</span>

kilometers away form the sun.
