Step-by-step explanation:
A fraction (from Latin fractus, "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A common, vulgar, or simple fraction (examples: {\displaystyle {\tfrac {1}{2}}}{\tfrac {1}{2}} and {\displaystyle {\tfrac {17}{3}}}{\displaystyle {\tfrac {17}{3}}}) consists of a numerator displayed above a line (or before a slash), and a non-zero denominator, displayed below (or after) that line. Numerators and denominators are also used in fractions that are not common, including compound fractions, complex fractions, and mixed numerals.

Step-by-step explanation:
Answer:
90 degrees
Step-by-step explanation:
Calculate whether an angle is 90 degrees using the Pythagorean Theorem.

Rod is paid $85 to install a screen door and $115 to install a wooden door. In one week he installed 18 doors and was paid a total of $1860. How many screen doors did Rod install?
Answer:Rod installed 7 screen doors
Step-by-step explanation:
Step 1
Let the number of screen door = x
And the number of wooden doors = y
since he installed 18 doors , we have that
screen door + wooden doors = 18
x + y = 18------ equation 1
Also the cost to install a screen door -= $85
and to install a wooden door = $115
And he was therefore paid a total of $1850
Therefore
85x + 115 y = $1860------- equation 2
Step 2----- Solving
x + y = 18------ equation 1
85x + 115 y = $1860------- equation 2
Multiplying equation 1 BY 85
85x + 85y= 1530------- equation 3
85x + 115 y = $1860------- equation 4
subtracting from equation 1 from (2)
115y- 85y= 1860-1530
30y=330
y = 330/30 = 11
To find x
x+ y=18
x= 18-y
x= 18-11= 7
Rod installed 7 screen doors and 11 wooden doors.

last year the cost of a season ticket for a rugby club £370. This year the cost of a season ticket for the club has been increase to £450. write down the increase in the cost of season ticket as a fraction of last years cost.
Answer:
[tex]\frac{80}{370}[/tex] OR [tex]\frac{8}{37}[/tex]
Step-by-step explanation:
So first you find the difference between the new cost and the old cost:
450 - 370 = 80
So the increase was 80.
When you write it as a fraction you write the increase ( 80 ) over the starting cost ( 370 ).
Thus the answer becomes [tex]\frac{80}{370}[/tex]
But you can always reduce it to its lowest terms thus:
[tex]\frac{8}{37}[/tex]

How many ways can eight letters be arranged into groups of five where order matters and the first two letters are already chosen?
100

240
720
Answer:
120
Step-by-step explanation:
There are 120 ways can eight letters be arranged into groups of five where order matters and the first two letters are already chosen.
What is Combination?A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Since, we're dealing with a problem where the order matters and the first two letters are already chosen we need to subtract the number of letters and the number of available slots per group.
Here, We use the permutation formula to find the answer, but before that let's check values.
n = 8
k = 5
Now since there are two letters already chosen we have to deduct two from both the value of n and k.
n = 6
k = 3
Hence, we can use the permutation formula:
P (n, k) = n! / (n - k)!
P (6, 3) = 6! / (6 - 3)!
P (6, 3) = 120
Thus, There are 120 ways can eight letters be arranged into groups of five where order matters and the first two letters are already chosen

The price of a smart watch is $109.99 and the sales tax is 6.5%. What is the total cost of the smart watch? Enter your answer in the box.
Answer:
$117.14
Step-by-step explanation:
A "sales tax" refers to a specific amount of money (according to its percentage) that you need to pay other than the price of the good stated.
So, if the price of the smart watch is $109.99 and the sales tax is 6.5%, you have to know much is 6.5% of $109.99. This can be computed by using the multiplication operation.
109.99 x 6.5% (0.065) = $7.15 (this is the sales tax)
In order to know the total cost of the smart watch, you have to add the sales tax to the price of the smart watch.
$109.99 + $7.15 = $117.14
The total cost of the smart watch is $117.14

Linear parent function f(x)=x is graphed on the grid. Which graph best represents
h(x) = -f(x) + 3
Answer:
See graph image
Step-by-step explanation:
If f(x)=x, and we substitute f(x) into h(x), we get h(x)=-(x)+3. The graph of -x+3 is shown in the image attached.
The graph which best represents the function; h(x) = -f(x) + 3 is the graph of h(x) = -x + 3 as in the attached image.
The function, f(x) is given as; f(x) = x.
However, the required graph is the graph of;
h(x) = -f(x) + 3
where, f(x) = x.Therefore,
h(x) = -x + 3Therefore, the graph of h(x) has intercept, h(x) = 3 and slope, m = -1 as in the attached image.

Find the values of x and y.
X= __
Y= __
Answer:
x = 20
y = 100
Step-by-step explanation:
To figure out x do this.
3x + 2x = 7x - 40 (collect like terms)
5x = 7x -40 (subtract 7x on both sides)
-2x = -40 (divide by -2 on both sides)
x = 20
Plug in to get y
Since 7x - 40 and y are vertical they equal the same amount
7(20) - 40 = y (multiply 7 by 20)
140 - 40 = y (collect like terms)
100 = y

Which scatterplot has a correlation coefficient closest to r = –1?
A coefficient of r = -1 is a negative so the dots would move downward as they move to the right ( higher dots are on the left side, lower dots on the right side. As the coefficient gets closer to -1 the dots form more of a straight line then being scattered across the graph.
The last graph, which is marked with the blue dot is the correct one.
The last scatterplot (option D) has a correlation coefficient closest to r = -1.
What is correlation coefficient?The correlation coefficient describes how one variable moves in relation to another.A positive correlation coefficient indicates that the two move in the same direction.A negative correlation coefficient tells you that they instead move in opposite directions.A correlation coefficient of zero suggests no correlation at all.For given situation,
When the y variable tends to decrease as the x variable increases, we say there is a negative correlation between the variables.
i.e., it must have negative correlation coefficient.
If we observe the last scatterplot i.e., option (D), then it must have negative correlation coefficient.
Therefore, the correct answer is option (D)

A van travels 180 miles on 12 gallons of gas. At that rate, how much gas will it need to travel 330 miles
Answer: 22 gallons of gas.
The amount of gas needed to travel 330 miles will be 36.67 gallons.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The rate is the ratio of the amount of something to the unit.
For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
A van travels 180 miles on 12 gallons of gas. Then the rate is given as,
Rate = 20 / 180
Rate = 0.1111 gallons per mile
At that rate, the amount of gas needed to travel 330 miles will be given as,
⇒ 330 x 0.1111
⇒ 36.67 gallons
The amount of gas needed to travel 330 miles will be 36.67 gallons.

Five times the second of three consecutive odd integers is thirteen less than three times the sum of the first and third integers. Find the largest odd number.
Answer: 15
Step-by-step explanation:
suppose; three consecutive odd integers are x; x + 2; x+ 4 (x is a odd integer)
because Five times the second of three consecutive odd integers is thirteen less than three times the sum of the first and third integers
=> 5(x + 2) = 3( x +x +4) - 13
<=> 5x + 10 = 6x + 12 - 13
<=>6x - 5x = 10 + 13 - 12
<=> x = 11
=> the largest odd number is 11 + 4 = 15
The largest of the three consecutive odd integers which could be written as a, a+2 and a + 4 is 15
Let the integers be : a, a + 2, a + 4
Creating a mathematical equation using the scenario given.
5(a + 2) = 3(a + (a + 4)) - 13
Open the bracket bracket
5a + 10 = 3(2a + 4) - 13
5a + 10 = 6a + 12 - 13
5a + 10 = 6a - 1
Collect like terms
5a - 6a = - 1 - 10
-a = - 11
a = 11
The largest integer = a + 4 ; 11 + 4 = 15
Therefore, the largest of the consecutive odd integers is 15
