Answer:

808 km

Step-by-step explanation:

So in 9 hours, 1818 km are traveled.

     In 4 hours, x km are traveled.

We can setup a proportion with this information to solve for x.

\frac{9}{4}=\frac{1818}{x}

Cross multiply:

9x=1818(4)

Divide both sides by 9:

x=\frac{1818(4)}{9}

x=808

Find a ∩ b if a = {2, 5, 8, 11, 14} and b = {1, 3, 5, 7}. {1, 2, 3, 5, 7, 8, 11, 14} {5}
Maslowich

The intersection of given set a and b is a∩b = {5}.

According to the given question.

We have two sets a and b.

a = {2, 5, 8, 11, 14}

And, b = {1, 3, 5, 7}

As, we know that "the intersection of two sets A and B is the set of all those elements which are common to both A and B. Symbolically, we can represent the intersection of A and B as A ∩ B".

Since, only the element which is common to set a and set b is 5.

Thereofore, the intersection of given set a and b is given by

a∩b = {5}

HELP ME PLEASE LIKE PLEASE I DONT UNDERSTAND THIS MATH
mafiozo [28]

Given that:

- A race car game takes 6 points each time the player hits a cone.

- You must find the integer that represents the change in total points if the player hits 10 cones.

It is important to remember that the Set of Integers contains the negative numbers, the positive numbers, and zero.

Then, by analyzing the data given in the exercise, you can identify two integers that must be multiplied, in order to calculate the total points if the player hits 10 cones. These are:

\begin{gathered} 10\text{ } \\ -6 \end{gathered}

Since the game takes 6 points from the player each time this hits a cone, the integer that represents the points taken from the player must be negative.

In order to multiply the integers, you need to remember the Sign Rules for Multiplication:

\begin{gathered} +\cdot+=+ \\ -\cdot-=+ \\ +\cdot-=- \\ -\cdot+=- \end{gathered}

Therefore, you get this result:

(10)(-6)=-60

Hence, the answer is:

A certain city divides naturally into ten district neighborhoods. How might a real estate appraiser select a sample of single-fa
Marysya12 [62]

Answer:

An appropriate method is to generate a simple random sample of all single-family homes in the city or a stratified random sample by taking a simple random sample from each of the ten district neighborhoods.

Step-by-step explanation:

Since, the city is very large and it is divided into ten districts. So, collecting sample from one district or any particular are did not give the correct estimate of whole city. So, the appropriate method to collect sample is taking the sample randomly from each district and this type of sampling method is called Stratified Sampling.

A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 96m long and 74m wide.
Oduvanchick [21]

Answer:

11402.66 m^{2}

Step-by-step explanation:

The width of rectangle is the diameter of the semi-circle part

Area of one semicircle is given by \frac {0.5\pi d^{2}}{4}

Total area of semi circle will be 2\times\frac {0.5\pi d^{2}}{4}

Substituting 74 m for d and \pi as 3.14 we obtain

Total area semi-circle=2\times\frac {0.5*3.14\times 74^{2}}{4}=4298.66 m^{2}

Area of rectangle is given by the product of length and width

Rectangular area=96 m*74 m=7104 m^{2}

Total area of rectangular and semi-circles will be

4298.66 m^{2}+7104 m^{2}=11402.66 m^{2}

Therefore, area of training field is 11402.66 m^{2}
