(Brainliest to whoever answers correctly) What is the area of the trapezoid?

Answer:

Indeed, the given triangle is a right triangle.

Step-by-step explanation:

A triangle is formed by the following three points: [tex]A(x,y) = (x_{1}, y_{1})[/tex], [tex]B(x,y) = (x_{2}, y_{1})[/tex] and [tex]C(x,y) = (x_{2}, y_{2})[/tex]. Then, we construct the following vectors:

[tex]\overrightarrow {BA} = (x_{2}-x_{1}, y_{1}-y_{1})[/tex]

[tex]\overrightarrow{BA} = (x_{2}-x_{1}, 0)[/tex] (1)

[tex]\overrightarrow{BC} = (x_{2}-x_{2}, y_{2} - y_{1})[/tex]

[tex]\overrightarrow{BC} = (0, y_{2}-y_{1})[/tex] (2)

If triangle ABC is a right triangle, then [tex]\overrightarrow{BA}\,\bullet\,\overrightarrow{BC} = 0[/tex]. By (1) and (2) we have this expression:

[tex](x_{2} - x_{1})\cdot (0) + (0)\cdot (y_{2} - y_{1}) = 0[/tex]

Therefore, the given triangle is a right triangle.

The true statement would be A. The theoretical probability of landing on violet is 1/3.

Probability which is derived theoretically, irrespective of what outcome comes, is called theoretical probability.

Probability which is based on the outcomes of experiments performed is called experimental probability.

Suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events that belong to E, and total cases are the size of the sample space.

A spinner has 4 equal sections. After spinning the spinner 15 times, the results are recorded in a table.

The true statement would be A. The theoretical probability of landing on violet is 1/3.

Answer:

1st Option;

j = 4.5

k = 2

Step-by-step explanation:

Let's solve for "j" first:

=> We know that by the definition of midpoint segment theorem we can say;

3j = 5j - 9

0 = 5j - 3j - 9

0 = 2j - 9

0 + 9 = 2j

9 = 2j

9/2 = j

4.5 = j

=> Now that we have j-value we use the same method to solve for k-value;

6k = k + 10

6k - k = 10

5k = 10

k = 10/5

k = 2

Therefore;

j = 4.5

k = 2

So the first option would be correct!

Hope this helps!

Answer

y=1/3x+1

Step-by-step explanation:

to be perpendicular, the slope has to be the opposite reciprocal

Answer:

Part A: one solution:

Part B: x = 3, y = 4.

1) Part A: how many solutions does the pair of equations for lines A and B have?

The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.

In this case, there are two straight lines, which intersect in one and only one point.

Hence, the system has one solution.

2) Part B: what is the solution to the equations of lines A and B?

The solution is the pair of coordinates of the intersection point. It is (3, 4).

Therefore, the solution is x = 3, y = 4.

Answer:

y = 10

Step-by-step explanation:

Given y varies inversely as x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k use the condition x = 4 when y = 15 , then

15 = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )

60 = k

y = [tex]\frac{60}{x}[/tex] ← equation of variation

When x = 6 , then

y = [tex]\frac{60}{6}[/tex] = 10

Answer:

The answer is 3

Step-by-step explanation:

The equation that represents the number of hours, h, Erica rented the scooter is 25h + 12 = 73.

Consider variable h represents the number of hours Erica rented the scooter.

The term 25h represents the cost of the gas fee, which is $25 multiplied by the number of hours.

The term 12 represents the cost per hour of renting the scooter.

The equation states that the sum of the gas fee and the rental fee per hour equals the total cost of $73.

Therefore, the correct equation is:

25h + 12 = 73, which represents the number of hours Erica rented the scooter.

Answer:

88cm^3

Step-by-step explanation:

The volume of a pyramid is the base times height divided by 3. First, we can find the area of the base. We have a right triangle with a base of 8 and a height of 6. The area of a triangle is the base times height divided by 2. This gives us:

8 * 6 ÷ 2 = 24cm^2

We can see that 11cm is the height as it is perpendicular to the base. We can set up an expression from the formula mentioned at the beginning:

11 * 24 ÷ 3 = 88cm^3
