solve for x please!!!!

Answers

11) Since the triangle has a pair of congruent base angles, it is an isosceles triangle which means that the two pairs of legs are congruent.

Make them equal to each other in an equation.

5x = x + 20

Subtract x from both sides.

4x = 20

Divide both sides by 4.

x = 5

12) The two legs are congruent so that means the base angles must be congruent. First find the measure of the base angles. Create an equation:

x + x + 50 = 180

Combine like terms.

2x + 50 = 180

Subtract 50 from both sides.

2x = 130

Divide both sides by 2.

x = 65

Now make the base angle plus x equal 180, because they form a straight line.

65 + x = 180

Subtract 65 from both sides.

x = 115

13) You know the vertex angle (top angle) is 90 degrees because it is supplementary to a right angle. The triangle is isosceles because the two legs are congruent, so make the base angles plus 90 add up to 180 in an equation.

x + x + 90 = 180

Combine like terms.

2x + 90 = 180

Subtract 90 from both sides.

2x = 90

Divide both sides by 2.

x = 45

Describe the type of angles formed when you divide a circle into 4 equal parts

Answers

we know that

when a circle is divided into four equal parts, we will get 4 right angles
so
360°/4=90° each part

see the attached figure to better understand the problem

When we divide a circle into 4 equal parts, the angles formed are the right angles.

When a circle is divided into 4 equal parts, we get 4 quarters of the circle.

What is a quarter of a circle?

The area that is intercepted by two radii that are at 90° to each other and a quarter portion of the circumference of a circle is known as a quarter circle.

In a quarter of a circle, the angle between radii is 90 degrees.

So, When we divide a circle into 4 equal parts, the angles formed are the right angles.

Hence, When we divide a circle into 4 equal parts, the angles formed are the right angles.

Of the 34 cars in a parking lot, 20 are green, 8 are gold, and the rest are black. What are the odds against the next car leaving the lot being black?

Answers

The odds against the next car leaving the parking lot being black are calculated by finding the number of black cars (6) and using the formula (Total cars - Black cars) : Black cars, which results in odds of 14:3.

To answer the question regarding the odds against the next car leaving the parking lot being black, we need to calculate the number of black cars and then the odds.

There are a total of 34 cars in the lot, with 20 green and 8 gold, so the rest are black.

To find the number of black cars, subtract the number of green and gold cars from the total:
34 (total cars) - 20 (green cars) - 8 (gold cars) = 6 (black cars).

The odds in favor of an event are the ratio of the probability of the event happening to the probability of it not happening. Therefore, the odds against an event are just the opposite -- the ratio of the probability of the event not happening to the probability of it happening.

To calculate the odds against picking a black car, we use this ratio:
Odds against a black car = (Total cars - Black cars) : Black cars
Odds against a black car = (34 - 6) : 6
Odds against a black car = 28 : 6
Odds against a black car = 14 : 3.

So, the odds against the next car leaving the lot being black are 14:3.

find the value of sin2a, if tana=-12/5 in the fourth quadrant

Answers

[tex]\tan a=-\dfrac{12}5[/tex]

Recall the following identities:

[tex]1+\tan^2a=\sec^2a=\dfrac1{\cos^2a}[/tex]
[tex]\cos^2a=\dfrac{1+\cos2a}a[/tex]

from which we get

[tex]1+\left(-\dfrac{12}5\right)^2=\dfrac1{\cos^2a}[/tex]
[tex]\implies\cos^2a=\dfrac{25}{169}[/tex]

Since [tex]a[/tex] is in the fourth quadrant [tex]\left(\dfrac{3\pi}2<a<2\pi\right)[/tex] we know that [tex]\cos a[/tex] should be positive, so when we take the square root here, we should take the positive root.

[tex]\implies\cos a=\sqrt{\dfrac{25}{169}}=\dfrac5{13}[/tex]

Now recall that

[tex]\cos^2a+\sin^2a=1[/tex]

and since [tex]a[/tex] is in the fourth quadrant, we expect [tex]\sin a[/tex] to be negative. So,

[tex]\sin^2a=1-\cos^2a=\dfrac{144}{169}\implies\sin a=-\sqrt{\dfrac{144}{169}}=-\dfrac{12}{13}[/tex]

One final identity:

[tex]\sin2a=2\sin a\cos a[/tex]

from which we get

[tex]\sin2a=2\cdot\left(-\dfrac{12}{13}\right)\cdot\dfrac5{13}=-\dfrac{120}{169}[/tex]

The easiest way to solve this question is to use each of the given order pairs, substitute with them in the equation and check whether the equation is satisfied or not.

The given equation is:
2x - 3y = 18

1- For (0,8):
2(0) - 3(8) = -24 .....> not equal to 18 .....> wrong choice

2- For (2,5):
2(2) - 3(5) = -11 .....> not equal to 18 .....> wrong choice

3- For (3,-4):
2(3) - 3(-4) = 18 .....> equal to 18 ......> correct choice

4- For (6,2):
2(6) - 3(2) = 6 .....> not equal to 18 ......> wrong choice

Based on the above, the correct choice is (3,-4)

If x has a value of 3, what is the area of the square? Show all of your steps. Previous Powered by LinkIt!

Answers

Part 1:
 The parimeter of the square by definition is given by:
 P = 4L
 Substituting values:
 P = 4 (2x + 4)
 Rewriting we have:
 P = 8x + 16

 Part 2:
 For x = 5 we have:
 P = 8 (5) + 16
 P = 40 + 16
 P = 56

 Part 3:
 The area of the square is:
 A = L ^ 2
 Substituting values:
 A = (2x + 4) ^ 2
 For x = 3 we have:
 A = (2 (3) + 4) ^ 2
 A = (6 + 4) ^ 2
 A = (10) ^ 2
 A = 100

What is the total number of outcomes in the sample space for Tossing a coin and spinning a spinner with 5 equal sections

Answers

2/5 i believe 
because a coin has two sides ( heads or tails) then the spinner is 5 equal sections so 2/5 <3
hope it helps

There are 10 possible outcomes in the sample space when tossing a coin and spinning a spinner with 5 equal sections.

When tossing a coin and spinning a spinner with 5 equal sections, the total number of outcomes in the sample space can be calculated by multiplying the number of outcomes for each event.

For the coin toss, there are 2 possible outcomes: heads (H) or tails (T).

For spinning the spinner, there are 5 possible outcomes: each of the 5 sections.

So, the total number of outcomes in the sample space is the product of these two numbers:2×5=10.

a new parking lot is being built for a medical office. the expression representing the number of parking spots in the new lot is 15x/4-9 where x represents the number of parking lots in the first row. how many spots are in the parking lot if there are 32 parking spots in the first row?

Answers

111 parking spots. 15x32 = 480 480 divided by 4 is 120 and 120 - 9 = 111

Answer:

The number of spots in the parking lot if there are 32 parking spots in the first row =111.

Step-by-step explanation:

We are given that a new parking lot is being built for a medical office.

We are given that

The expression representing the number of parking spots in the new lot =[tex]\frac{15x}{4}-9[/tex]

Where x= The number of parking lots in the first row

We have to find number of spots in the parking lot when parking spots in the first row is 32.

The number of parking spots in the first row =x=32

Substitute the value of x in the given expression then we get

Number of spots in the parking lot =[tex]\frac{15\times 32}{4}-9[/tex]

Number of spots in the parking lot=[tex]\frac{480}{4}-9[/tex]

The number of spots in the parking lot=120-9

The number of spots in the parking lot=111.

Hence, the number of spots in the parking lot if there are 32 parking spots in the first row=111.
