Answer:

Option (B). Perimeter of the quadrilateral ABCD= 14.6 units

Step-by-step explanation:

From the figure attached,

Coordinates of the vertices are A(3, 5), B(1, 3), C(3, -1), D(5, 3).

Length of AB = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}

                      = \sqrt{(3-1)^2+(5-3)^2}

                      = \sqrt{8}

                      = 2.83 units

Length of AD = \sqrt{(3-5)^2+(5-3)^2}

                      = \sqrt{8}

                      = 2.83 units

Length of BC = \sqrt{(1-3)^2+(3+1)^2}

                      = \sqrt{20}

                      = 4.47 units

Length of DC = \sqrt{(5-3)^2+(3+1)^2}

                       = \sqrt{20}

                       = 4.47 units

Perimeter of the quadrilateral = AB + AD + DC + BC

                                                 = 2.83 + 2.83 + 4.47 + 4.47

                                                = 14.6 units  

Option (B) is the answer.

Dennis decided he wanted to go to the carnival. The carnival charges $6.00 for entry and $1.50 for each ride.
myrzilka [38]

We want to create a linear equation to model the given situation.

A) c(r) = $6.00 + $1.50*r

B) 19 rides.

We know that the carnival charges $6.00 for entry plus $1.50 for each ride.

A) With the given information we can see that if you ride for r rides, then the cost equation will be:

c(r) = $6.00 + $1.50*r

Where c(r) is the cost for going to the carnival and doing r rides.

B) If you have $35.00, then we can solve:

c(r) = $35.00 =  $6.00 + $1.50*r

Now we can solve the equation for r.

$35.00 =  $6.00 + $1.50*r

$35.00 -  $6.00 = $1.50*r

$29.00 = $1.50*r

$29.00/$1.50 = r = 19.33

Rounding to the next whole number we get: r = 19

This means that with $35.00, Dennis could go to 19 rides.

The equation Y equals 4/10 X describes the number of kilometers y that a van travels in x minutes. What is the constant speed of
Mekhanik [1.2K]

Answer:

\frac{4}{10}=0.4 kilometers per hour.

Step-by-step explanation:

We have been given an y=\frac{4}{10}x, which describes the number of kilometers y that a van travels in x minutes. We are asked to to find the constant speed of the van in terms of hours.

We can see that van travel \frac{4}{10}x kilometers in x hours. To find the constant speed of van, we will substitute x=1 in our given equation as:

y=\frac{4}{10}(1)

y=\frac{4}{10}

Since van travels \frac{4}{10} kilometers in one hour, therefore, constant speed of van is \frac{4}{10} kilometer per hour or 0.4 kilometers per hour.
