Therefore the group of order integers from least to greatest is -8, 5, 6 , |-7|, 8
At 6pm on October 23rd you exchange 100 JPY and receive 12.33 GSD
a state the rate you will take and how much you expect to receive?
Answer:
0.123 GSD are expected to be received by each JPY.
Step-by-step explanation:
The exchange rate is the ratio of GSD per each JPY, that is:
[tex]x = \frac{12.33\,GSD}{100\,JPY}[/tex]
[tex]x = 0.123\,\frac{GSD}{JPY}[/tex]
Which means that 0.123 GSD are expected to be received by each JPY.
In a test (+5) marks are given for every correct answer and (-2) marks are given for every incorrect answer . Roy answered all the questions and scored 30 marks though she got 10 correct? Find the total number of sums .
Answer:
20 questions
Step-by-step explanation:
Given
[tex]Correct \Marks= +5[/tex]
[tex]Incorrect\ Marks= -2[/tex]
[tex]Score\ Obtained = 30[/tex]
[tex]Number\ of\ correct\ answers = 10[/tex]
Required
Number of questions answered
First, we need to get the total correct marks obtained by Roy
This is calculated by multiplying the correct marks by number of correct answers
[tex]Total = +5 * 10[/tex]
[tex]Total = +50\ marks[/tex]
Subtract this from the total scores obtained; This gives the total incorrect answer obtained by Roy
[tex]Incorrect = Scores\ Obtained - Total[/tex]
[tex]Incorrect = 30 - (+50)[/tex]
Open bracket
[tex]Incorrect = 30 - 50[/tex]
[tex]Incorrect = -20[/tex]
Divide this by -2 to get the number of incorrect answers
[tex]Incorrect\ Answers = \frac{-20}{-2}[/tex]
[tex]Incorrect\ Answers = 10[/tex]
Add this to the number of correct answers to give the total number of question answered
[tex]Total = Correct\ Answers + Incorrect\ Answers[/tex]
[tex]Total = 10 + 10[/tex]
[tex]Total = 20[/tex]
Hence, Roy answered a total of 20 questions

1.Which numbers below could be classified as integers? 2.Which number belongs in the shaded portion of the diagram below?
Answer:
1). Option (3)
2). Option (D)
Step-by-step explanation:
1). Integers are the numbers which are whole numbers with negative or positive notations.
Integers can't be a fraction or a number with decimal.
Out of the numbers given,
-18 and 4 will be the integers
Option (3) is the correct answer.
2). Shaded portion of the diagram represents the rational numbers excluding integers,
By the definition of the rational numbers, any number which can be written as a fraction is a rational number.
Rational numbers → All numbers given are the rational numbers
Integers → [tex]\frac{16}{4}=4, -\frac{30}{5}=6, -\frac{32}{8}=-4[/tex]
Therefore, only one number [tex]\frac{30}{9}[/tex] will lie in the shaded region.
Option (D) will be the answer.

simplify (3x + 2)(4x - 4)
Answer:
12x² - 4x - 8
Step-by-step explanation:
Use FOIL method
(3x + 2)(4x - 4) = 3x*4x + 3x*(-4) + 2 *4x + 2*(-4)
= 12x² - 12x + 8x - 8 {add like terms}
= 12x² - 4x - 8
Hint: 3x * 4x -----> Multiply the coefficients = 3 *4 = 12 and then multiply the variables and for multiplying the two variable, add the powers
x*x =[tex]x^{1+1)=x^{2}[/tex]
3x * 4x = 12x²
There are 1,332 people under the age 20 in Pierce City. This represents 14% of the total population. What is the total population
Answer:
The total population = 9514.2857143 people.
Step-by-step explanation:
Let the total population be represented by X
In the question, we are told that,1332 people are under the age of 20 and this value = 14% of the total population.
Therefore, the total population is calculated as
14% of X = 1332
14/100 × X = 1332
14X/100 = 1332
Cross Multiply
14X = 1332 × 100
X = 1332 × 100/14
X = 9514.2857143
Therefore, the total population = 9514.2857143 people.

given the area, find the dimension of a rectangle
The length of a rectangle is 12m less than three times its width, its area is 63 square meters.
Answer:
Width W = 7 m
Length L = 9 m
Step-by-step explanation:
Area of a rectangle = L * W
Area = 63 m²
L = 3W - 12
Area = L * W
66 = (3W - 12) * W
63 = 3W² - 12W
3W² - 12W - 63 = 0 ( solve W by using quadratic equation)
-(-12) ± √ -12² - 4 * 3 * (-63)
W = -------------------------------------------
2 * 3
W = 7 ; W = - 3
therefore use W = 7 m
solve for L:
L = 3W - 12
L = 3(7) - 12
L = 9 m
check:
Area = L * W
63 = 9 * 7
63 = 63 ----- OK
Translate to an algebraic expression: 3 times the difference of a number and 4 is 33
Answer:
3 x (14-3) = 33
Step-by-step explanation:
The algebraic expression will be : 3(x - 4) = 33
Given,
3 times the difference of a number and 4 is 33

Step-by-step explanation:
f^-1(x) is the inverse of f(x). That means that f(x) = 2x - 6 becomes...
x = 2y - 6
2y - 6 = x
2y = x + 6
y = 1/2x + 3.
When x = 2...

A right triangle has a perimeter of 24 cm and a hypotenuse of 10 cm. Find the length of the other two sides.
Answer:
One of the sides is 6 cm and the other is 8 cm
Step-by-step explanation:
Let's call the unknown sides a and b. From the perimeter information (24 cm) we have:
a + b + hypotenuse = 24
a + b + 10 = 24
a + b = 14
b = 14 - a
So now we can right the Pythagorean theorem as follows:
[tex]a^2 + b^2 = hypotenuse^2\\a^2 + (14-a)^2=10^2\\a^2+ 14^2-28\,a+a^2=100\\2\,a^2-28\,a +96=0\\2\,(a^2-14\,a+48)=0\\2\,(a^2-6\,a-8\,a+48)=0\\2(a\,(a-6)-8\,(a-6))=0\\2\,(a-6)\,(a-8)=0[/tex]
and from this expression in factor form to be zero a must be 6 or a must be 8.
Therefore the solutions are a = 6 (and therefore b = 14 - 6 = 8)
or a = 8 (and therefore b = 14 - 8 = 6)
Perimeter of triangle = Sum of all sides.
One side of triangle = 10 cm
Measure of other two sides will be → 24-10
Other two sides sum will be = 14 cm
Let's assume one side as x and other as 14-x
Now hypotenuse is of 10 cm
According to Pythagorean theoram
Hypotenuse² = Perpendicular ² + base²
→ 10² = (x)² + (14-x)²
→ 100 = x² + (14-x)²
(a-b)² = a²+b² -2ab
→ 100 = x² + 196 + x² -28 x
→ 100 = 2x² + 196 - 28x
Taking 2 commen both sides
→ 50 = x² -14x + 98
→ 0 = x² -14x +98-50
→ x² -14 x +48 = 0
Factorising :-
→ x² - 6x - 8x + 48 = 0
→ x( x -6) -8(x -6) = 0
→ (x-6)(x-8) = 0
→ x = 6 or x = 8
So x is 6 or 8
Other two sides of triangle are 6 cm and 8 cm
Use the percent proportion to solve for X. 16 is 32% of x. Find the value of 1.

I dont get the question, is there suposed to be a chart?
Step-by-step explanation:
is the ratio 5:6 equivalent to 3:4
Answer:
No!
Step-by-step explanation:
This question is essentially asking if [tex]\frac{5}{6}[/tex] = [tex]\frac{3}{4}[/tex]
Well we can easily tell that it doesn't, but if we want to check, we can do cross multiplication.
So we are trying to find out if 5(4) = 3(6).
5(4) = 20 and 3(6) = 18.
[tex]20 \neq 18[/tex] so [tex]5:6 \neq 3:4[/tex]
They are not equal!

Marcella divided 40.8 gallons of paint amount 8 containers. how much paint is in each container?
Answer:
5.1 gallons
Step-by-step explanation:
Using the information provided, we know that there is of course 40.8 gallons of paint to be divided into 8 containers. This means we must use a division problem to figure out our answer.
We are splitting the 40.8 gallons into the 8 containers so that means our dividend is 40.8 and our divisor is 8. With this information, we can go ahead and put this into an expression of:
40.8/8
If you have a calculator, you can plug that equation in to get 5.1, but if you don't then a bit of easy long division will get you the same answer of 5.1 gallons.
Answer: 51 gallons

How many x or y intercepts can a quadratic function have?
0-2 x-intercepts and 0-1 y-intercept
2 x-intercepts and 1 y-intercept
0-2 x-intercepts and 1 y-intercept
1-2 x-intercepts and 0-1 y-intercept
Answer:
0-2 x-intercepts and 0-1 y-intercepts
Step-by-step explanation:
A quadratic function can have anywhere from 0 to 2 x-intercepts. This is possible because a function can have 0, 1, or 2 solutions.
A parabola can also have either 0 or 1 y intercepts. It is possible for the function to not intercept the y axis at all, and it is also possible for it to intercept it exactly one time.

Sorry it’s the best quality photo I could get
Explanation:
The idea is to isolate y getting it by itself. We can do this a number of ways, but possibly the quickest way is to add y to both sides
x/2 - y + 6 = 0
x/2 + 6 = 0+y
x/2 + 6 = y
y = x/2 + 6
This is now in slope intercept form, more or less. We could rewrite the x/2 as (1/2)x to get
y = (1/2)x + 6
Then compare this to y = mx+b and note the slope is m = 1/2 and the y intercept is b = 6.
