Let's called the train that traveled south train A, and the train that traveled east train B

After 3 hours, train A is 180 miles South

and Train B is 150 miles East

Using Pythagoras, distance between is sqrt(180^2 + 150^2)

30 sqrt(6^2 + 5^2) = 30sqrt(36 + 25) = 30sqrt 61 = 234.307 miles

After 3 hours, train A is 180 miles South

and Train B is 150 miles East

Using Pythagoras, distance between is sqrt(180^2 + 150^2)

30 sqrt(6^2 + 5^2) = 30sqrt(36 + 25) = 30sqrt 61 = 234.307 miles

Space in the box = volume

volume = length x width x height

box 1 volume = 15 x 20 x 10 = 3000

box 2 volume = 15 x 20 x 14 = 4200

how much space is left = box 2 - box 1 = 1200 inches

volume = length x width x height

box 1 volume = 15 x 20 x 10 = 3000

box 2 volume = 15 x 20 x 14 = 4200

how much space is left = box 2 - box 1 = 1200 inches

**Answer:**

The commission rate is** 0.29** or **29%**

**Step-by-step explanation:**

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

Before we can solve this problem, we need to create a formula that calculates the total amount of Tristen's payment. The formula would be the following,

Where:

**T**is the total pay**b**is the base pay**r**is the rate of commission**s**is the total sales

Now that we have the formula we can plug in the values from the question and then solve for the rate of commission **(r)**

.... subtract **31,050** on both sides

.... divide both sides by **97,200**

Now we can see that the commission rate is** 0.29** or **29%**

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

**Answer with Step-by-step explanation:**

There is a set of 100 observations with a mean of 40 and a standard deviation of 0.

standard deviation=0

means that variance=0 (since, variance=square of standard deviation)

now, variance is calculated as sum of the square of deviations of all the data points from the mean

i.e. if x1,x2,...xn are n observations, then

is the variance

since variance is zero means that each of is zero

i.e. xi=mean for each i=1,2,...n

Hence here each of the observation is equal to mean=40

**Hence, the value of the smallest observation in the set is:**

** 40**

Given that the 3 arcs are congruent, it means they have the same angle.

A circle measures 360 degrees, thus, let us divide it into three parts to get the arc length of the 3 arcs RC, CS, and SM which is in Circle A.

360 degrees / 3 = 120 degrees

Again, the three arcs are congruent so the length of arc RC is 120 degrees, same with arcs CS and SM.
