The angle k will be 100 in the triangle KJL and the side HI will be 4.

What is triangle?

A triangle is a plane figure formed by the three sides having sum of the angles 180 degree.

Here in triangle KJL we can see that it is a isosceles triangle So the angle j and angle L will be 40.

Now we can solve

[tex]\angle L + \angle J + \angle K=180\\\\\\40+40+\angle K=180\\\\\\\angle k=180-80\\\\\\\angle k=100[/tex]

Now the side HI in the triangle HGI

We can see that the triangle HGI is the equilateral triangle so the all sides will be equal so

[tex]HI=IG=GH=4\[/tex]

Hence the angle k will be 100 in the triangle KJL and the side HI will be 4.

find the value of each variable
x=
y=
z=

Answers

Answer:

Step-by-step explanation:

A 45 degree angle in a right triangle produces 2 equal sides. In this case z and the perpendicular line are equal. So that's were we'll start. Then you move on to the 60 degree angle to get x and y.

Finding z

z^2 + z^2 = (24√2)                    Combine the left

2z^2 = 24^2 * 2                         Divide both sides by 2

2z^2/2 = 24^2/2

z^2 = 24^2                                 Take the square root of both sides

√z^2 = √24^2

z = 24

Finding x and y

The perpendicular = 24. Because it is a 60 degree angle that's given, we can do this without a calculator.

Tan 60 = opposite over adjacent

sqrt(3) = Perpendicular / z                      Multiply both sides by z

z*sqrt(3) = perpendicular

The above calculation tells us the perpendicular is 24

z*sqrt(3) = 24                                           Divide by sqrt 3

z = 24/√3

z = 24/1.73

z = 8√3

Finding x

Use Pythagoras to determine x

Perpendicular^2 + (8√3)^2 = x^2

24^2 + 8^2*3 = x^2

576 + 192 = x^2

768 = x^2

√x^2 = √768

x = 27.71

Math hw areas urgent

Answers

Answer:

See below.

Step-by-step explanation:

The side of the square is k.

The area of the square is k².

The diameter of the circle is k.

For a circle, radius = diameter/2.

The radius of the circle is k/2.

Formula for area of circle: A = πr².

Here, the radius, r, is k/2.

The area of the circle is π(k/2)² = (πk²)/4

The shaded area is the difference between the area of the square and the area of the circle.

shaded area = k² - (πk²)/4

We are told that the shaded area = A

A = k² - (πk²)/4

Multiply both sides of the equation above by 4.

4A = 4k² - πk²

Answers

Answer:

I wouldn't say this is entirely correct, but I think it's 45%.

Step-by-step explanation:

If you started with $90 and it was reduced 20%, than 25% MORE, the final percentage that was lowered would be the 20% and 25% added together.

The answer is 45%.

(Please do tell me if I got this wrong!!)

The original price reduced to 60%.

What is a percentage?

A percentage is a ratio or number that can be expressed as a fraction of 100. Additionally, it is denoted by the symbol "%."

On September 1, a dress was priced at $90. On October 1, the price was reduced by 20%.

That means,

the price is now = $90 - (90 x 20 /100) = $72

On November 1, the price was further reduced by 25% of the October 1 price.

The price is now = $72 - ( 72 x 25 / 100) = $54

To find the percentage of original price;

The percentage of original price

= 5400 / 90

= 60%

Therefore, the final price is 60% of the original price.

Step-by-step explanation:

this is a nice parallelogram.

that means it has 2 pairs of equal and parallel sides (opposite of each other), 2 pairs of equal angles (also opposite of each other).

as in every quadrilateral the sum of all angles is 360°.

and because of the 2 pairs of equal (yet opposite) angles, every angle combines with one of its neighbors to 180°.

so,

(3x + 5) + (8x - 12) = 180

3x + 5 + 8x - 12 = 180

11x - 7 = 180

11x = 187

x = 17

and then the angle P is

a car travels at 49 km/hour how far does it travel in a 12 hour day​

Answers

Answer:   2.88 km.

Step-by-step explanation:

We will discuss here how to find the distance when speed and time are given.

When speed and time are given, the distance travelled is calculated by using the formula:

Distance = Speed × Time

The unit of time in speed should be the same as that of the given time.

Solved examples to calculate distance when speed and time are given:

1. How much distance will be covered in 5 hrs at a speed of 55 km per hour?

Solution:

Distance covered in 1 hour = 55 km.

We know, Distance = Speed × Time

Distance covered in 5 hrs = 55 × 5

                                  = 275 km.

Therefore, distance covered in 5 hrs = 275 km.

2. A bus travels at a speed of 45 km/hour. How far will it travel in 36 minutes?

Solution:

Speed = 45 km/hour

Time = 36 minutes

      = 36/60 Hour (Since we know, 1 hour = 60 minutes)

      = 3/5 hour

Distance = speed × time

           = 45 × (3/5) km

           = (45 × 3)/5 km

           = 27 km.

3. How much distance will be covered in 7 hrs at a speed of 62 km per hour?

Solution:

Distance covered in 1 hour = 62 km.

We know, Distance = Speed × Time

Distance covered in 7 hrs = 62 × 7

                                     = 434 km.

Therefore, distance covered in 7 hrs = 434 km.

4. Mike drives his car at a speed of 70 km per hour. How much distance will he cover in 3 hours 30 minutes?

Solution:

Speed of the car = 70 km/hr

Time taken         = 3 hours 30 minutes

                        = 3 ½ hours.

Distance covered in 1 hour = 70 km

Distance covered in 3 ½ hour = 70 × 3 ½ km

                                          = 70 × 7/2 km

                                          = 245 km.

5. How much distance will be covered in 1 ½ hour at a speed of 32 m per minute?

Solution:

[1 ½ hr = (60 + 30) minutes = 90 minutes].

Distance covered in 1 minute = 32 metres.

Distance covered in 90 minutes = 32 × 90 = 2880 m.

We know, 1 m = 1/1000 km.

                     = 2880/1000 km.

                     = 2.88 km.

Hope this helps!

Find The Mean, Median, and mode range of 13, 25, 7, 28, 42, 7, 15, 23, 1, 17. ​

Answers

Step-by-step explanation:

Mean :

13 + 25 + 7 + 28 + 42 + 7 + 15 + 23 + 1 + 17.

= 178

178 ÷ 10

= 17.8

Median =

13, 25, 7, 28, (42, 7,) 15, 23, 1, 17

= 42 + 17

= 59 ÷ 2

= 29.5

Range :

42 - 1

= 41

Hope it helps :))

Answer:

Mean- 17.8 Median- 16 Mode- 17.8

Step-by-step explanation:

1. Put the numbers in ascending order.

1, 7, 7, 13, 15, 17, 23, 25, 28, 42

2. Look for the median. The median is the number located in the middle of a set of numbers. In this case, the median is going to be between 15 and 17 because they are both in the middle. This means that the median will be 16.

1, 7, 7, 13, 15, 17, 23, 25, 28, 42

3. Find the mode. The mode is the number you see the most in a set of numbers. In this case, there are two 7's so 7 is the mode of this set.

1, 7, 7, 13, 15, 17, 23, 25, 28, 42

4. Find the mean. The mean is the overall average of a set of numbers. To find the average, find the sum of all the numbers in the set and divide it by the number of integers there are. In this case, there are ten integers, so we'll find the sum (178) and divide it by 10 to get a mean of 17.8.

[tex]\frac{1+7+7+13+15+17+23+25+28+42}{10}[/tex] = 17.8

5. Find the range. The range is basically the difference between the lowest and highest values in a set of numbers. The lowest number is 1 and the highest is 42. So, we'll subtract the two to get a range of 41.

1, 7, 7, 13, 15, 17, 23, 25, 28, 42

42 - 1 = 41

First, we need to find the vertex. The x-value of the vertex is:

h = -12/2*6 = -1

To get the y-value of the vertex, we need to evaluate the function in h, so we get:

y = 6 - 12 - 10 = -16

Then the vertex is (-1, -16)

This means that the vertex form is:
