3. (05.02 LC) You can draw a quadrilateral with no parallel lines and at least one right angle. (1 point) True or False​

Answers

Answer:  True

======================================================

Explanation:

If you have exactly one right angle, then it is possible to have no parallel lines.   See the diagram below. Refer to the upper figure.

If you had exactly 2 right angles, then that would form a trapezoid. A trapezoid has exactly one pair of parallel lines.

If you had 4 right angles, then it would form a rectangle. Any rectangle is a parallelogram, so we have 2 pairs of parallel lines by this point.

It's not possible to have a quadrilateral with exactly 3 right angles (and the fourth angle is some non-right angle). This is because all four angles of any quadrilateral must add to 360 degrees.

Answer:

C. [tex]9\pi[/tex]

Step-by-step explanation:

We proceed to solve for [tex]x[/tex] by the Pythagorean Theorem:

[tex](x+1)^{2} = (x-1)^{2} + (2\cdot x - 4)^{2}[/tex] (1)

[tex]x^{2} + 2\cdot x + 1 = (x^{2}-2\cdot x + 1) + (4\cdot x^{2}-16\cdot x + 16)[/tex]

[tex]x^{2} + 2\cdot x + 1 = 5\cdot x^{2}-18\cdot x + 17[/tex]

[tex]4\cdot x^{2} -20\cdot x + 16 = 0[/tex]

[tex](2\cdot x)^{2} -10\cdot (2\cdot x) + 16 = 0[/tex]

[tex](2\cdot x -8)\cdot (2\cdot x -2) = 0[/tex]

There are two different solutions:

[tex]x_{1} = 4[/tex], [tex]x_{2} = 1[/tex]

A solution of [tex]x[/tex] is considered realistic when the length of every side of the triangle is a not negative number.

[tex]x_{1} = 4[/tex]

[tex]UV = 2\cdot (4) - 4[/tex]

[tex]UV = 4[/tex]

[tex]WU = 4 - 1[/tex]

[tex]WU = 3[/tex]

[tex]WV = 4 + 1[/tex]

[tex]WV = 5[/tex]

[tex]x_{2} = 1[/tex]

[tex]UV = 2\cdot (1) - 4[/tex]

[tex]UV = -2[/tex]

[tex]WU = 1 - 1[/tex]

[tex]WU = 0[/tex]

[tex]WV = 1 + 1[/tex]

[tex]WV = 2[/tex]

The only realistic set of solutions is for [tex]x = 4[/tex], and the radius of the circle is represented by the line segment [tex]WU[/tex]: [tex]r = 3[/tex]

And the area of the circle ([tex]A[/tex]) is calculated from the following formula:

[tex]A = \pi\cdot r^{2}[/tex]

[tex]A = \pi\cdot (9)[/tex]

[tex]A = 9\pi[/tex]

The correct answer is C.

Chris is playing a card game with his friends. The game uses only the four aces from a standard deck of cards. For each move, a player draws one card, replaces it, and then draws the second card.

Answers

Answer:

1/4

Step-by-step explanation:

Let's call the aces for hearts, diamonds, clubs, and spades. So,  are red and [tex] c, s[/tex] is black.

Since the first card is replaced, the two picks are identical. This means that the sample space is given by all the possible couple

There are 16 such couples (we have four choices for the first card, and the same four choices for the second card). Now let's compute the odds in our favor to deduce the probability of winning:

If we want a player to draw two cards of the same color, the following couples are good:

so 8 possible couples over 16. This means that a player's probability of drawing two cards of the same color is 8/16 = 1/2.

Similarly, the probability of drawing a red ace first and then a black ace is represented by the following couples:

which are 4 over the same 16 as above, thus leading to a probability of 4/16 = 1/4.

Jodie ran at an average speed of 6 km/h for 10 minutes.
How far did she run in km?

Answers

Answer:

Distance cover by Jodie = 1 kilometer

Step-by-step explanation:

Given;

Speed of Jodie = 6 kilometer/ hour

Total time Jodie ran = 10 minutes

Find:

Distance cover by Jodie

Computation:

Total time Jodie ran = 10 minutes = 10 / 60 = 0.1667 hour

Distance = Speed x time

Distance cover by Jodie = Speed of Jodie x Total time Jodie ran

Distance cover by Jodie = 6 x 0.1667

Distance cover by Jodie = 1.002

Distance cover by Jodie = 1 kilometer

Solve the equation. 6g = 48 what does g equal?

Answers

Answer:

8

Step-by-step explanation:

First we need to figure out what g equals

Since 6 x 8 = 48 your answer would be 8

6 x 8 = 48

~ LadyBrain

The value of g that satisfies the equation is 8.

To solve the equation 6g = 48 and find the value of g, we can isolate the variable g by dividing both sides of the equation by 6:

6g / 6 = 48 / 6

This simplifies to:

g = 8

Therefore, g equals 8. By dividing both sides of the equation by 6, we find that when g is multiplied by 6, it results in 48. Hence, the value of g that satisfies the equation is 8.

Adjacent angles are those angles that are always placed next to each other in such a way that they share a common vertex and a common side but they do not overlap each other.

The sum of the measures of a pair of adjacent angles can be any number, including 180 degrees, but it does not have to be 180 degrees.

Write 1/3 x^2 - 4x + 17 in vertex form

Answers

Answer:

f(x)=−4(x+ 41 ) 2 − 4 11

Explanation:

The given function is

f(x) = - 4 {x}^{2} - 2x - 3f(x)=−4x 2 −2x−3

To write the function is vertex form, we need to complete the square.

We first factor -4 to get:

f(x) = - 4 ({x}^{2} + \frac{1}{2} x) - 3f(x−4(x2 + 21 x)−3

Add and subtract the square of half the coefficient of x.

f(x) = - 4( {x}^{2} + \frac{1}{2} x + \frac{1}{16} ) - \frac{1}{4} - 3f(x)=−4(x 2 + 21 x+ 16 1 )− 41 −3

We factor the perfect square trinomial and simplify to get:

f(x) = - 4( {x + \frac{1}{4} )}^{2} - \frac{11}{4}f(x)=−4(x+ 41 ) 2 − 4 11
