4. Find the value of x.
(4x - 10)
Answer:
x = 20°Step-by-step explanation:
We know,
The angle of a straight line is 180°
therefore,
90 + (4x - 10) + x = 180°5x = 180 - 90 + 105x = 190 - 905x = 100x = 20°Hope it helps !!what is a domain and a rang piece piecewise function

At Dapper Dave's annual end-of-season sale, every necktie in the shop gets marked down. Dillon purchased 6 neckties during the sale. Each necktie cost $5 less than its full price. He paid a total of $162. What is the cost of each necktie at full price?
Answer:
6 times 5 = 30
the total is $162
162 + 30 = $192 at full price

Which of the expressions is rational
Answer:
the third one
Step-by-step explanation:
the square root of 25 is 5. 5+2 = 7.
this is a rational number (the set of all integers and fractions).
the other 2 portions contain at least one element that is not rational. and so the sum with such a number is not rational.
45 and 7 are no square numbers, and therefore the square root of these numbers contains a neverending chain of digits after the decimal point without having any repeating pattern. these are real numbers but not rational numbers.

in the figure four quarters each of radius 2 m are removed from a rectangle find the perimeter
Answer:
in the figure four quadrants each of radius 2 m are removed from a rectangle.
I have attached the required figure, assuming the sides of a rectangle based on given measurement of quadrants.
Let the sides of a rectangle be 2 m × 4 m.
The radius of quadrant is 2 m ( given )
From given, we have
Area of figure = Area of 4 quadrants - Area of rectangle .
= 4 × π/4 × r² - l × w
= 4 × π/4 × 2² - 2 × 4
= 3.14 × 4 - 8
= 12.4 - 8
= 4.4 m²
Therefore, the area of the figure is 4.4 m²
Perimeter of figure = Perimeter of 4 quadrants - Perimeter of rectangle
= 4 × [ 0.5πr + 2r ] - 2 ( l + w )
= 4 × [ 0.5 × 3.14 × 2 + 2 × 2 ] - 2 ( 4 + 2 )
= 4 × [ 3.14 + 4 ] - 2 (6)
= 28.56 - 12
= 16.56 m
the perimeter of the figure is 16.56 m

A spinner is divided into five sections numbered 1 through 5. Juana records the number the spinner lands on for each of 50 spins. She computes and graphs the relative frequencies for each number. Which of the following describes the probability distribution? A bar graph entitled Relative Frequency of Numbers Spun has x on the x-axis and Probability on the y-axis. The probability of 1 is 0. 5; 2 is 0. 12; 3 is 0. 12; 4 is 0. 12; 5 is 0. 12. Constant symmetric negatively skewed positively skewed.
The distribution of the probability of the given data is a Positive Skewed Probability distribution.
Given to us
A spinner is divided into five sections numbered 1 through 5. Juana records the number the spinner lands on for each of the 50 spins. She computes and graphs the relative frequencies for each number
What is a Probability distribution?It is a type of distribution in which the distribution has a constant probability, therefore, the probability of each event occurring is equal.
What is symmetric distribution?Symmetric distribution is the type of distribution where the left side of the distribution and the right side of the distribution are mirror images to each other, therefore, they are symmetrical.
What is Negatively Skewed Probability distribution?Negatively Skewed Probability distribution is a type of distribution of the probability where the right side(tail) of the distribution is more concentrated than the right side.
What is Positive Skewed Probability distribution?Positive Skewed Probability distribution is a type of distribution of the probability where the left side of the distribution is more concentrated than the right side.
Which of the following describes the probability distribution of the given data?Since in the given graph probability of every number occurring from 2 to 5 is equal to 0.12(12%), while the probability of number 1 occurring is 0.5(50%).
Thus, the distribution of the probability is towards the right end of the graph.
Hence, the distribution of the probability of the given data is a Positive Skewed Probability distribution.

A standard set of dominoes contains 28 tiles, with each tile having two sides of dots from 0 to 6. Of these tiles, 7 have the same number of dots on each side. If four players each randomly choose a tile, without replacement, what is the probability that each chooses a tile with the same number of dots on each side?
Answer:
first person has a chance of 7/28 or 1/4
The second = 6/27 or 2/9
The third = 5/26
And the fourth = 4/25
multiplying these together you get 4 / 2340=

This histogram below shows how long students is a class slept the night before. How many student slept less than 12 hours?
Answer:
18 students
Step-by-step explanation:
Assuming there are 21 students in the class,
3 of them slept for 12 - 15 hours
8 of them slept for 8 - 11 hours
8 of them slept for 4 - 7 hours
2 of them slept for 0 - 3 hours
Now we just add the number of students that slept under 12 hours
8 + 8 + 2 = 18 students

Julia's school is selling tickets to the annual dance competition. On the first day of ticket sales
the school sold 5 senior citizen tickets and 9 student tickets for a total of $149. The school took
in $103 on the second day by selling 7 senior citizen tickets and 3 student tickets. Find the price
of a senior citizen ticket.
The price of a senior citizen ticket is [x] dollars.
Senior tickets (x)
Child tickets (y)
First day: 3x + 5y = 70
second day: 12x + 12y = 216
Solve the system of equations (use elimination)
Multiply first equation by -4 -4(3x + 5y = 70), which makes it
-12x - 20y = -280
(+)12x + 12y = 216 add to second equation
-8y = -64
divide by -8. y = 8
Plugin the y value to either equation ( I will choose first equation)
3x + 5(8) =70
3x+ 40 = 70
3x = 30
x = 10
Senior tickets are $10, child tickets are $8

On a road trip, Jessica drove twice as many miles as Amy did. Together, they drove 312 miles. How many miles did Amy drive? Cant seem to get the answer to this so please someone help! Thanks!
Answer:
Amy drove 104 miles
Step-by-step explanation:
let 'a' = miles Amy drove
let '2a' = miles Jessica drove
a + 2a = 312
3a = 312
a = 312/3
a = 104
2a = 208
Check: 104+208 should equal 312 and it does
=========================================================
Explanation:
x = number of miles Amy drove2x = number of miles Jessica drove, since she drove twice the distance as Amy didCombine the two expressions: x+2x = 3x
The two girls traveled a total distance of 312 miles, so 3x = 312
Divide both sides by 3 to solve for x. You should get x = 104
Amy drove 104 miles and Jessica drove 2*104 = 208 miles
Check:
Amy + Jessica = 104 + 208 = 312
The answer is confirmed.
Which table respents a non-linear relationship between x and y?
Answer:
B, because y does not have a continuous pattern
Step-by-step explanation:
Two cars that are 150 miles apart start driving toward each other on parallel roads. The average speed of the first car is 60 miles per hour. The average speed of the second car is 55 miles per hour. Which equation can be used to determine t, the time it takes for the two cars to pass each other?
A table showing Rate in mile per hour, Time in hours, and Distance in miles. The first row shows First Car and has 60, t, and 60 t. The second row shows Second Car and has, 55, t, and 55 t.
60t – 55t = 0
60t + 55t = 1
60t + 55t = 150
60t – 55t = 150
Answer:
60T + 55T = 150
Step-by-step explanation:
[tex]T(60+55)=150\\115T=150[/tex]
[tex]T=150/115=1.304 hr[/tex]
The cars takes 1.304 hrs (1h 18 min aprox) to pass each other
