One train traveled south at 60 mph. The other traveled east at 50 mph. How far apart were the trains after 3 hours?

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

QUESTION POSTED AT 28/03/2020 - 12:39 PM

Tristen is a salesman whose base pay plus commissions amounted to $59,238 last year. if his base pay was? $31,050 and he made $97,200 in sales last year, what was his rate of commission? a) 61% b) 52% c) 29% d) 32%

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,

T = b + (r*s)

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)

59,238 = 31,050 + (r*97,200) .... subtract 31,050 on both sides

 28,188= r*97,200 .... divide both sides by 97,200

0.29 = r

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.

Krypton-91 is a radioactive substance that decays very quickly. The function Q(t)=Qoe^-kt models radioactive decay of krypton-91. Q represents the quantity remaining after t seconds and the decay constant k is approximately 0.07. How long will it take a quantity of krypton-91 to decay t o10% of its origional amount? round your answer to the nearest second.

Answer:

32.894 seconds ≈ 33 seconds

Step-by-step explanation:

Function : Q(t)=Q_0 e^{-kt}

The function models radioactive decay of krypton-91.

The decay constant k is approximately 0.07.

Q_0 denotes initial amount .

We are require to find How long will it take a quantity of krypton-91 to decay to 10% of its original amount

\Rightarrow 10\%\times Q_0

\Rightarrow 0.10\times Q_0

So, we neet to find t at which Q(t)=0.10 Q_0

0.10 Q_0=Q_0 e^{-0.07t}

0.10 =e^{-0.07t}

Taking log both sides

\log0.10 =-0.07t \log e

\log0.10 = -0.07t \times 0.434294481903

-1 = -0.0304006137332t

\frac{-1}{-0.0304006137332} = t

32.894= t

Thus it will take 32.894 seconds ≈ 33 seconds a quantity of krypton-91 to decay to 10% of its original amount.

A clerk in the sports department of a store is stacking tennis balls in the shape of a square pyramid. The top layer has 1 ball, the second layer has 4 balls, the third layer has 9 balls, and so on, as shown below. Which of the following represents the number of balls in the first 8 layers of the pyramid? A. a series that is arithmetic B. a series that is geometric C. a series that is neither arithmetic nor geometric D. a series cannot be used to represent this situation.

Answer:

It is a series that is neither arithmetic nor geometric

Step-by-step explanation:

We are given that The top layer has 1 ball, the second layer has 4 balls, the third layer has 9 balls, and so on,

The pattern is

1^2 = 1

2^2 = 4

3^2 = 9

4^2 = 16

n^2 is the pattern where n is the position in the series.

For arithmetic series Common difference: d=a_2-a_1=a_3-a_2

So,  d=4-1\neq 9-4

Thus it is not an arithmetic series .

For Geometric series there must be an common ratio : r = \frac{a_2}{a_1}=\frac{a_3}{a_2}

So, r = \frac{4}{1}\neq\frac{9}{4}

Thus it is not geometric series.

Thus Option C is correct.

It is a series that is neither arithmetic nor geometric

Joel is laying pipe for a sprinkler system before he plants his lawn. The lawn is a rectangle, 15 feet long and 8 feet wide. He needs to lay a piece of pipe that will run along the diagonal of the lawn. It will divide the area of the lawn into two right triangles. What will be the length of the pipe? A. 120 feet B. 17 feet C. 23 feet D. 289 feet

Answer: B is the right answer. Diameter of the given rectangular lawn=17 feet.


Step-by-step explanation:

Given: A rectangular lawn 15 feet long and 8 feet wide.

To find the diagonal of lawn such that it will divide the area of the lawn into two right triangles. [i.e. diagonal will be the hypotenuse]

So by Pythagoras theorem of right triangles,

hypotenuse^2=perpendicular^2+base^2\\\Rightarrow\ diagonal^2=length^2+width^2\\\text{substitute the values of length and width,we get}\\\Rightarrow\ diagonal^2=15^2+8^2=225+64=289\\\Rightarrow\ diagonal=\sqrt{289}= \sqrt{17\times17}=17

Therefore diameter of the given rectangular lawn=17 feet.

Ryan places a mirror on the ground 42 feet from the base of a tree. He walks backwards until he can see the top of the tree in the middle of the mirror. At that point, Jason's eyes are 6 feet above the ground and he is 7 feet from the image in the mirror. What is the height of the tree? A. 49 feet B. 36 feet C. 56 feet D. 39 feet

Answer: B. 36 feet

Step-by-step explanation:

Let h denotes the height of tree

.

According to the question, it can be seen that there is a proportional relationship [Property of similar triangles]  .

\text{i.e.}\dfrac{\text{Tree's height}}{\text{Distance between tree and mirror }}=\dfrac{\text{Jason's height}}{\text{Distance between Jason and mirror}}\\\\\\\Rightarrow\dfrac{h}{42}=\dfrac{6}{7}\\\\\\\Rightarrow\ h=\dfrac{6\times42}{7}=36

Hence, the height of the tree= 36 feet.
