Answer:
9
Step-by-step explanation:
a quotient is the result of dividing one number by the other, so we know 8 is being divided by 2
8÷2 is 4
five more just means adding 5
so we are left with 4+5 which =9

WHAT IS BODMAS ?Children can use the acronym BODMAS to help them remember the right order to carry out mathematical operations while solving problems. B-Brackets, O-Orders (powers/exponents or roots), D-Division, M-Multiplication, A-Addition, and S-Subtraction are all abbreviated as BODMAS.
The order of operations (or operator precedence) in mathematics and computer programming refers to a set of rules that represent standards for which operations to carry out first in order to evaluate a specific mathematical expression. For instance, since the advent of contemporary algebraic notation, multiplication has been given a higher priority than addition in mathematics and most computer languages.
As a result, 1 + (2 3) = 7 rather than 1 + (2 3) = 9 is the value assigned to the expression 1 + 2 3. Exponents were first used in the 16th and 17th centuries, when addition and multiplication were given priority. Exponents could only be used as a superscript to the right of their base. Consequently, 3 + 52 = 28 and 3 52 = 75.
CALCULATIONfirst add the total amount of flour =
= [tex]1\frac{1}{2} + 2\frac{3}{4}[/tex]
= 1.5 + 2.75

Write a linear function f(x)=mx+b for the table
The standard form the linear function is f(x)= -3x-3.
Linear FunctionAn equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=5x+3. Where:
m= the slope. It can be calculated for Δy/Δx .
b= the constant term that represents the y-intercept.
For the given example: m=5 and b=3.
You should replace in the minimum two given values for x and y in the standard form for a linear equation mx+b . Thus, you will write a system linear where from it, you can find the coefficients m and b. See below.
For x=0 and y=-3y=mx+b
-3=0*m+b
-3=b
For x=-2 and y=3y=mx+b
3= -2*m+b
Now, you find b=-3, then
3= -2*m-3
3+3= -2m
6=-2m
m= -3
Thus, you can write f(x)= -3x-3.

Show how 2/5 + 4/10 is the same as 4/5
Answer:
Explained through Step-by-step (Showed Work)
Step-by-step explanation:
Question: Show how 2/5 + 4/10 is the same as 4/5
Step-by-step:
2/5 and 4/10 are fractions. (So is 4/5)
To add fractions together, we need the denominators to be the same. This means that the bottom number of 2/5, which is 5 and the bottom number of 4/10 which is 10 have to be the same.
The easiest way to do this is to simplify 4/10. To simplify 4/10, we divide both the numerator (top number) and the denominator (bottom number) by the Greatest Common Factor.
In this case, 2 is the Greatest Common Factor because 4 divided by 2 is 2 and 10 divided by 2 is 5.
so, 4/10 can be simplified to 2/5.
Now, we can add 2/5 and 2/5 together by only adding the numerators. 2 + 2 = 4
so, 2/5 + 2/5 = 4/5
4/5 = 4/5
Therefore, 2/5 + 4/10 is the same as 4/5.
Hope this helps
10. Sam earns a salary of $25,000 while Charlie earns a salary of $30,000. They each receive
a $2000 raise. Which of the following is true?
(a) Sam's raise is larger than Charlie's in both absolute and relative terms.
(b) The raises are the same in absolute terms, but Sam's is larger in relative terms.
(c) The raises are the same in relative terms, but Sam's is larger in absolute terms.
(d) The raises are the same in absolute terms, but Charlie's is larger in relative terms.
If the salary of Sam is $25000 and Charlie earns $30000 and each get a raise of $2000 then the statement "The raises are the same in absolute terms, but Charlie's is larger in relative terms" is true.
Salary of Sam = $25000
Raise in Sam's Salary = $2000
New Total Salary = $25000 + $2000 = $27000
Salary of Charlie = $30000
Raise in Charlie's Salary = $2000
New Total Salary = $30000 + $2000 = $32000
Hence the absolute value of their salaries are same but Charlie will get more in relative terms.
Hence, option d is correct.

Please help me with this geometry question. Answer should be entered like this (answer, answer) thank you
Answer:
Q is the point (3, 4).
Step-by-step explanation:
The formulae for the coordinates of a point (h, k) which divides a line joining the points (x1, y1) and (x2, y2) in the ratio m : n is:
h = (mx2 + nx1) / (m + n), k = (my2 + my1)/(m+n)
Now we have S = (x1, y1) = (-2, -6) and T = (x2, y2) = (5, 8) and
m = 5 and n = 2.
So here, for point Q:
h = (5*5) + 2*-2)/(2+5)
= 21/7
= 3.
k = (5*8 + (-6*2) / 7
= 28/7

in class, we proved that the number of ways of tiling a $1 \times n$ rectangle with $1 \times 1$ and $1 \times 2$ tiles is $f {n 1}.$ (a) use a tiling argument to give a combinatorial proof that \[f 1 f 2 f 3 \dots f n
Here is a straightforward recursion you may employ to calculate the value.
let's use rectangles with integer aspects to represent the quantity of tilings of a $2 instances n$ rectangle as $T(n)$. There are $22n-2$ techniques to accomplish this if no rectangles of height $2$ are hired, wherein case we lessen to two wonderful times of the $1 times n$ state of affairs. If no longer, we set a situation based at the top-proper rectangle's $2 height. With the preliminary conditions $T(0)=1$ and $T(1)=2$, this results in $$T(n)=22n-2+sum k=0n-1 T(okay)+sum 0leq k ell leq n-1T(ok)22(n-ell-1)$. The center term inside the recursion corresponds to the case where the rightmost rectangle of top $2$ is absolutely the rightmost rectangle inside the tiling.It should be noted that the formula $2n-1$ for the $1 times n$ case is incorrect if $n=0$.

The equation can be modelled to a real scenario where every purchase can be use to calculate sales tax.
How to find a real world situation that models an equation?The equation to be modelled is as follows:
y = 1 / 20x
let
x = The total price of purchases
y = The amount of sales tax
This simply means a person pays 1 / 20 or 5% of every purchase he/she makes.
The total price of the purchase(including tax) is x while the actual amount of tax paid is y.
Let's say you buy a goods worth 400 dollars. Let's calculated the tax as follows:
x = $400
Therefore,
y = 1 / 20 × 400
y = 1 / 20 × 400
y = $20

For the given function f(x) = x^2 - 2x + 1, the difference quotient is {2x + h - 2]
How to find the difference quotient for the function f(x)?
Here we have the function f(x) = x^2 - 2x + 1
And we want to find the difference quotient, which is:
( f(x + h) - f(x))/h
Replacing the actual function there we get:
[ (x + h)^2 - 2*(x + h) + 1 - x^2 + 2x - 1]/h
Now we can simplify the numerator, we will get:
[ x^2 + 2xh + h^2 - 2x - 2h + 1 - x^2 + 2x -1]/h
[2xh + h^2 - 2h]/h

alysha is at a local library with her best friend. they've noticed a lot of cute boys in the library, and alysha bets that of the next twenty people to enter the library, exactly 12 will be cute boys. assuming there is a 50% chance that the next person to walk into the library is a cute boy, what is the probability that alysha will win the bet?
The probability that Alysha will win the bet is 0.12013
Let ‘x’ be the number of cute boys from next 20 persons that enter the library
And assume x be the integral values from 0 to 20
Given, the probability is 50% that the next person that enters the library is a cute boy,
total number of trials n=20 and probability of success p=50% = 0.5 = 1/2.
Hence, the p.m.f of X is given by
fX(x) = 20Cx(1/2)x(1−1/2)20−x
=20Cx(1/2)x(1/2)20−x
=20Cx(1/2)20
=20!(20−x)!x!⋅ 1220
=0,1,2,…,19,20
and the probability that X=x,
thus
P(X=x)=20!(20−x)!x!⋅1220
x=0,1,2,…,19,20
P(X=x)=20!(20−x)!x!⋅1220
x=0,1,2,…,19,20.
In particular, for X=x=12
P(X=12)=20!(20−12)!12!⋅1220
=20!8!12!⋅1220
≈0.12013
Hence, the probability that exactly 12 persons of the next 20 persons that walk into the library are cute boys is only approximately 0.12013.
Therefore, 0.1203 is less than 0.5, then it is more probable that Alysha will lose the bet than win it.

Jenna can't wait to play in her new sandbox! Her mom fills the sandbox with seven 50-pound bags of sand. Then, Jenna uses her bucket to dump out sand 10 times. If she dumps out 8 ounces of sand each time, how many pounds of sand are left in the sandbox?
Answer:
345 pounds
Step-by-step explanation:
Each bucket dumps out 8 ounces of sand
8 ounces = 1/2 pound
So total sand dumped 10 times = 1/2 x 10 = 5 pounds
Originally sandbox had 7 x 50 = 350 pounds of sand
Sand left in box = 350 - 5 = 345 pounds

The probability that the inspector finds exactly one nonconforming part is 0.4091.
What is combination?Combination is a selection of items from a collection in which the order of selection is irrelevant. Probability is defined as the ratio of favorable outcomes to total outcomes.
Now, according to the question;
Let X represent the event in which the inspector discovers a nonconforming part.
An inspector selects three parts at random from among the twelve, and two cavities have been affected by a temperature malfunction, resulting in parts that do not meet specifications.
The total number of ways to select three parts from a total of twelve is ¹²C₃ = 220.
The number of possible ways for an inspector to identify just one defective part is:
²C₁×¹⁰C₂ = 2×45
²C₁×¹⁰C₂ = 90
The likelihood that the inspector will discover exactly one nonconforming part is provided by:
P (x=1) = (²C₁×¹⁰C₂)/¹²C₃
= 99/220
P (x=1) = 0.4091
The inspector has a 0.4091 chance of finding exactly one nonconforming part.
Now, the probability that inspector finds no nonconforming parts is given by:
P (x=0) = ¹⁰C₃×¹²C₃
= 120/220
P (x=0) = 0.5455
Therefore, the inspector has a 0.5455 chance of finding exactly none nonconforming part.
