The sum of all the angles of this polygon is

(n-2)180

Where m is the number of corners

(5-2)180

3*180

540

Hence

Sum of all angles=540

139+92+71+9x+5x=540

302+14x=540

14x=540-302

14x=238

Dividing both sides by 14

Kinetic energy =[tex]\frac{1}{2} mv^{2}[/tex]

Here m = 1500 kg and v = 14 meter / second

Kinetic energy = [tex]\frac{1}{2} mv^{2}[/tex]= [tex]\frac{1}{2}\times 1500 \times 14^{2}[/tex] joule =147000 joule

2.

Here m = 2 unit and v = 5 units

Kinetic energy =[tex]\frac{1}{2} mv^{2}[/tex] =[tex]\frac{1}{2}\times 2 \times 5^{2}[/tex] units =25 units

3.

Here m= 2 units and v = 5 units

Kinetic energy =[tex]\frac{1}{2} mv^{2}[/tex] =[tex]\frac{1}{2}\times 4 \times 5^{2}[/tex]=5 0 units

4.

Here m= 2 units and v= 10 units

Kinetic energy =[tex]\frac{1}{2} mv^{2}[/tex]=[tex]\frac{1}{2}\times 4 \times 10^{2}[/tex]units = 200 units

The vertex form is [tex]y=(x-1)^{2} -6[/tex]

Step-by-step explanation:

The given equation [tex]y=x^{2} -2x-5[/tex] is a parabola. The vertex of the parabola is of the form [tex]y=ax^{2} +bx+c[/tex]  

The parameters of the parabola are [tex]a=1, b=-2[/tex] and [tex]c=-5[/tex]

The vertex of the x-coordinate is given by [tex]x=\frac{-b}{2a}[/tex]

Thus, substituting the values of a and b in [tex]x=\frac{-b}{2a}[/tex], we get,

[tex]\begin{aligned}x &=\frac{-(-2)}{2(1)} \\&=\frac{2}{2} \\x &=1\end{aligned}[/tex]

Now, substituting [tex]x=1[/tex] in [tex]y=x^{2} -2x-5[/tex], we get,

[tex]\begin{aligned}y &=1^{2}-2(1)-5 \\&=1-2-5 \\y &=-6\end{aligned}[/tex]

Thus, the vertex is [tex](1,-6)[/tex]

The equation of parabola to be in vertex form is [tex]y=a(x-h)^{2} +k[/tex]

where a is the coefficient of [tex]x^{2}[/tex], h is vertex of the x-coordinate and k is the vertex of the y-coordinate.

Hence, [tex]a=1, h=1[/tex] and [tex]k=-6[/tex]

Thus, substituting the values in the equation of the vertex form,

[tex]y=1(x-1)^{2} -6\\y=(x-1)^{2} -6[/tex]

Hence, the vertex form is [tex]y=(x-1)^{2} -6[/tex]

Answer: $7,864.32

Step-by-step explanation:

First you would do 100% -20% which would give you 80% (0.8)

1st year : $24,000 x 0.8 = 19,200

Then take your answer and times it by 0.8 again until you get to the 5th year

2nd year : $19,200 x 0.8 = $15,360

3rd year : $15,360 x 0.8 = $12,288

4th year : $12,288 x 0.8 = $9,830.40

5th year : $9,830.40 x 0.8 = $7,864.32

Therefore your final answer is $7,864.32

Final answer:

The resale value of the car after 5 years will be approximately $7,864.32.

Explanation:

To find the resale value of the car after 5 years, we need to calculate the depreciation rate each year and then apply it to the original purchase price. Since the resale value decreases by 20% each year, we can calculate the resale value after 5 years as follows:

After the first year, the resale value will be 80% of the original purchase price: $24,000 * 0.8 = $19,200.

After the second year, the resale value will be 80% of the previous year's resale value: $19,200 * 0.8 = $15,360.

After the third year, the resale value will be 80% of the previous year's resale value: $15,360 * 0.8 = $12,288.

After the fourth year, the resale value will be 80% of the previous year's resale value: $12,288 * 0.8 = $9,830.40.

After the fifth year, the resale value will be 80% of the previous year's resale value: $9,830.40 * 0.8 = $7,864.32.

Therefore, the resale value of the car after 5 years will be approximately $7,864.32.

Step-by-step explanation:

area if squre is πr^2

so...

[tex]\pi {r}^{2} = 3.14 \times 7 \times 7 = 153.86 {ft}^{2} [/tex]

r means radius and...radius is diameter/2

now we must subtract the area of the square

[tex] {a}^{2} = 10 \times 10 = 100 {ft}^{2} [/tex]

[tex]153.86 - 100 = 53.86 {ft}^{2} [/tex]

nearest answer is 50

Answer:

Step-by-step explanation:

r = 14/2 = 7 feet

Area of circle=πr²=22*7*7/7 = 22*7= 154 sq. feet

Area of square = side*side = 10*10 =100

Area of shaded region = Area of circle - Area of square

Answer:

20%

Step-by-step explanation:

let the percent be p

rewriting the expression:

p% of 170 is 34

or mathematically,

p% x 170 = 34

(p / 100) x 170 = 34   (divide both sides by 170)

p/100 = 34/170  (multiply both sides by 100)

p = (34 / 170)  x 100

p = 20

hence 34 is 20% of 170

Answer: yes , it is possible

Step-by-step explanation:

Let the first number be x and the second number be y .Then , the sum of the two numbers will be x + y , and their difference will be x - y.

Combining the two , we have :

x + y = 1 ............................... equation 1

x - y = 8 ................................. equation 2

solving the system of linear equation by substitution method. From equation 1 , make x the subject of the formula ,

x = 1 - y ...................... equation 3

Substitute equation 3 into equation 2 ,

1 - y - y = 8

1 - 2y = 8

add 2y to both sides

1 = 8 + 2y

subtract 8 from both sides

1 - 8 = 2y

- 7 = 2y

divide through by 2

y = [tex]\frac{-7}{2}[/tex]

y = - 3.5

substitute y = -3.5 into equation 3 to find the value of x , we have

x = 1 - y

x = 1 - ( - 3.5 )

x = 1 + 3.5

x = 4.5

Let us check :

x + y will be

4.5 + (-3.5) = 1

Also ,

x - y will be

4.5 - (-3.5)

⇒ 4.5 + 3.5 = 8

Answer:

C

Step-by-step explanation:

Slope-intercept form is y=mx+b. Y is y, m is the slope, x is x, and b is the y-intercept. The first thing you do is figure out the slope. The equation is (y2-y1)/(x2-x1). Then take 2 points from the table and substitute them in. I'll use the bottom two points: (4-2)/(2-1). You should get 2 as your answer. Substitute this in for m. Take a point from the table and substitute y in for y, x in for x. I'll use the last point: 4=2(2)+b. If I simplify further, I get 4=4+b, which means b is 0, and we won't need to put it in the equation.

Figure out the answer using the process of elimination: we know that because b=0, the answer can't be A or B. The slope is positive 2, which means that the answer can't be D. So it has to be C.

Answer:

Therefore the probability that in one turn James could roll an odd number and fip a heads on the quarter is  = [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex] = [tex]\frac{1}{4}[/tex].

Step-by-step explanation:

i) There are three odd numbered faces on the cube, that is the faces having 1, 3, and 5.

Therefore the probability of rolling an odd numbered face is = [tex]\frac{1}{6} + \frac{1}{6} + \frac{1}{6} = \frac{1}{2}[/tex] since the probability of rolling 1 = probability of rolling 3 = probability of rolling 5 = [tex]\frac{1}{6}[/tex]

ii) The probability of flipping a head on the quarter = probability of flipping a tail on the quarter = [tex]\frac{1}{2}[/tex]

iii) Therefore the probability that in one turn James could roll an odd number and fip a heads on the quarter is  = [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex] = [tex]\frac{1}{4}[/tex]

The probability that James could roll an odd number on a fair six-sided die and flip heads on a quarter in one turn is 1/4 or 25%.

The student is asking about the probability of two independent events happening simultaneously: rolling an odd number on a fair six-sided die and flipping heads on a quarter. To calculate the probability of both independent events occurring, we multiply the probabilities of each event.

The probability of rolling an odd number (1, 3 or 5) on a die is 3 out of 6 possibilities, which simplifies to 1/2 since there are three odd numbers out of six total numbers. The probability of flipping heads on a quarter is 1/2, as there are two sides to a coin and it is fair, meaning each side has an equal chance of landing face up.

Now, to find the combined probability, we multiply the probabilities of the independent events:

Combined probability = (1/2) x (1/2) = 1/4 or 0.25, which means there is a 25% chance to roll an odd number and flip heads in one turn.

1 oz --- ?

Then:

[tex]?=\frac{(1 oz)(\$1.68)}{3 oz}[/tex]

[tex]?=\$ 0.056[/tex]

This is the price in dollars, now we have to calculate it in cents, taking into account that [tex]100 cent=\$1[/tex]:

[tex]$ 0.056 \frac{100 cent}{\$1}=5.6 cents[/tex]  This is the price in cents of 1 ounce of tomato sauce

2) If Edward buys 60 cds for [tex]\$ 7[/tex] each, what is the cost of 60 cds?:

60 cds ---?

1 cd --- [tex]\$7[/tex]

[tex]?=\frac{(60 cds)(\$7)}{1 cd}[/tex]

[tex]?=\$ 420[/tex] This is what Edward spends in 60 cds for [tex]\$7[/tex] each

Now, we have to calculate how many cds Edward can buy for [tex]\$14[/tex] each and spend the same [tex]\$ 420[/tex]:

1 cd --- [tex]\$14[/tex]

? cds ---[tex]\$ 420[/tex]

[tex]?=frac{(\$ 420)(1 cd)}{\$14}[/tex]

I think it's histograms for the first blank; distribution for the second blank; frequency for the third and final blank.

Hope this helps please let me know if I'm wrong :)))

Histograms show the distribution and frequency for a set of values. Distribution is how the values are spread out or grouped, and frequency is how often a value occurs in a set of numbers.

A frequency distribution is like a detailed count of all the different values or groups of values in a data set. When data are collected, a histogram provides a visual representation of this distribution. The distribution of the data can be divided into various classes or bins, where the count or frequency of data falling into each bin is tallied. This tally helps to visualise patterns such as the center, spread, and overall shape of the data.
The histogram consists of contiguous rectangles, with the height of each bar corresponding to the frequency of data points within that class interval. The horizontal axis (x-axis) typically represents the values or categories of the dataset, while the vertical axis (y-axis) represents the frequency of occurrences. This graphical tool allows us to quickly ascertain which values are more prevalent and identify the spread or variability of the data, as well as the center, which is considered the middle or typical value of the dataset.
