How to find the perimeter of the triangle

Sliva [168]

Answer:

A. 26.2

Step-by-step explanation:

To find the perimeter of the triangle, you have to find the distances of all three lines and add them up.

<u>Line AB</u>

Let's start off by finding the distance of line AB.

We will use the formula, $d = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$ .

Point A is (-2,5) and Point B is (4,-3).

To substitute the values, it will get to $d = \sqrt{(4--2)^{2}+(-3-5)^{2}}$ which in other words is $d = \sqrt{(4+2)^{2}+(-3-5)^{2}}$ .

Now we have to solve the parenthesis to get $d = \sqrt{(6)^{2}+(-8)^{2}}$ .

Now we have to solve the exponents which would get to $d = \sqrt{36+64}$ .

Now we have to simplify the square root to $d = \sqrt{100}$ . In other words, that is $d = 10$ .

Line AB = 10

<u>Line BC</u>

Now let's find the distance of line BC.

We will use the same formula, $d = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$ .

Point B is (4,-3) and Point C is (0,-6).

To substitute the values, it will get to $d = \sqrt{(0-4)^{2}+(-6--3)^{2}}$ which in other words is $d = \sqrt{(0-4)^{2}+(-6+3)^{2}}$ .

Now we have to solve the parentheses to get $d = \sqrt{(-4)^{2}+(-3)^{2}}$ .

Now we have to solve the exponents which would get to $d = \sqrt{16+9}$ .

Now we have to simplify the square root to $d = \sqrt{25}$ . In other words, that is $d = 5$ .

Line BC = 5.

<u>Line AC</u>

Now let's fine the distance of line AC.

We will use the same formula, $d = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$ .

Point A is (-2,5) and Point C is (0,-6).

To substitute the values, it will get to $d = \sqrt{(0--2)^{2}+(-6-5)^{2}}$ which in other words is $d = \sqrt{(0+2)^{2}+(-6-5)^{2}}$ .

Now we have to solve the parentheses to get $d = \sqrt{(2)^{2}+(-11)^{2}}$ .

Now we have to solve the exponents which would get to $d = \sqrt{4+121}$ .

Now we have to simplify the square root to $d = \sqrt{125}$ . In other words, that is $d = 5\sqrt{5}$ . To round that, $d = 11.2$ .

Line AC = 11.2.

<u>Perimeter of Triangle ABC</u>

Perimeter of Triangle ABC = Line AB + Line BC + Line AC.

Perimeter of Triangle ABC = 10 + 5 + 11.2

Perimeter of Triangle ABC = 26.2

Tickets to a baseball game cost $12 for adults and $7 for children. How much will tickets cost for 3 adults and 4 children?

ludmilkaskok [199]

Answer:

So total cost of tickets = $64

Step-by-step explanation:

Given:

Cost of adult = $12

Cost of Children = $7

Total Adults = 3

Total children = 4

To Find:

Total Cost = ?

Solution:

We are given per person price and no of persons too now

Total cost = Cost of children ticket + Cost of Adults ticket

Now we will find the values

Cost of 3 adults ticket = total person * cost per person

= 3 * 12

=$36

Cost of 4 Children ticket = total person * cost per person

= 4 * 7

=$28

Now

Total cost = Cost of children ticket + Cost of Adults ticket

putting value

Total cost = 28 + 36

= $ 64

So total cost of tickets = $64

Which of the following statements are true? check all that apply.

Margaret [11]

<u>Answer:</u>

1 and 5 are correct.

<u>Step-by-step explanation:</u>

1. The mean is affected by outliers. - TRUE

(the mean is the average so each of its values affect it.)

2. The mean is always a more accurate measure of center than the median. - FALSE

(the mean gives a better idea of the values while the the central values for normal distributions are described using the median value.)

3. Removing an outlier from a data set will cause the standard deviation to increase. - FALSE

(it makes the data set more normal by reducing the standard deviation, not increasing it. )

4. If the data set’s distribution is skewed, then 95%of its values will fall between two standard deviations of the mean. - FALSE

(the 68-95-99.9 rule works for the normal distribution, but the skewed distribution.)

5. If a data set’s distribution to skewed to the right, its mean will be larger than its median. - TRUE

(the mean is always pulled towards the direction of the skewness.)
