LCM is 16
Step-by-step explanation:
2/3 - 1/2
There's something called whole fraction whereby the fractions should be multiplied to get the LCM 6
Here We Go!
2/2*2/3 - 3/3*1/2
The denominators are 2 and 3 and when multiplied. The above fraction will still give you the LCM to be 6
Write the following expression using a single exponent.
5^0 x 5^5
Choose all expressions that are equal to 16.02. #1 16 +0.02, #2 3.42 +8+4.6, #3 16.01 +1, #4 12.06 +3.14, #5 7.36 +8.66
Expression number #1, #2 and #5 are equal to 16.02 in the given question.
As per the question statement, we have to choose all expressions that are equal to 16.02
The options are
[tex]16+0.02[/tex][tex]3.42+8+4.6[/tex][tex]16.01 +1[/tex][tex]12.06+3.14[/tex][tex]7.36+8.66[/tex]Lets verify #1

stock was worth $2,486.95 before the loss. What was the stock worth after
?the loss
Answer:
Approximately $2,039.30
Step-by-step explanation:
Original value = $2,486.95
Value lost = 18%
100% value = $2,486.95
100% - 18% = 82% value remaining
.82 x 2,486.95 = 2039.299 or $2,039.30

5. If that same manufacturer miscalculates the demand of the market and manufactures 5,000 dozen of those sweaters, but only sells 3,000 dozen, what is the total profit from the sweaters? (Show your calculations.) $ profit.
If a manufacturer manufactures 5,000 dozen of sweaters, and sells 3,000 dozen of them only, then the total profit he/she earns from the these sweaters is [1000(3x - 5y)], assuming that the cost of manufacturing one sweater is "x" and the selling price of that sweater is "y".
As per the question statement, a manufacturer miscalculates the demand of the market and manufactures 5,000 sweaters, but sold only 3000 of them.
We are required to calculate the total profit earned by the manufacturer from the sale of the sweaters.
Since, no data about the manufacturing cost of the sweaters and their selling price is provided in the question statement, let us assume that the cost of manufacturing one sweater is "x" and the selling price of that sweater is "y". Solving with these variables will give us a generalized answer which we can use for any value.
Now, Since assumed that, manufacturing cost of one sweater is "x", then, manufacturing cost of 5000 sweaters will be [tex](5000*x)=5000x[/tex].
Similarly assumed that, selling cost of one sweater is "y", and then, selling cost of 3000 sweater will be [tex][(3000*y)=3000y][/tex].
Now, we know that,
[Profit = (Total Selling Cosy) - (Total Manufacturing Cost)],
Therefore, in this case, total profit from the sale of 3000 sweaters
[tex]=(3000y-5000x)\\=1000(3y-5x)[/tex].
Now, on using real integers or numbers in place of "x" and "y", if the value of Profit comes negative, it will mean, that for those values of "x" and "y", the manufacturer makes loss, not profit.
Profit: On sale of any goods, a person makes profit if he/she can sell the goods for a higher value than what they had bought for, or what they had manufactured at and is thus, calculated as the difference of total selling price of the goods and the manufacturing cost or buying price of them.Loss: This is the exact opposite of profit and is calculated as the difference of manufacturing cost or buying price of the goods and their selling price.To learn more about Profit and Loss, click on the link below.

the expression sinx + cotx cosx can be simplified to what
after simplifying the expression sinx + cotx cosx, we get the result as cosec x.
We are given the expression:
sinx + cotx cosx
We need to simplify the expression.
We know that cot x can also be written as
cot x = cos x / sin x
Substituting it in the expression, we get that:
= sin x + ( cos x / sin x ) cos x
opening the brackets, we get that:
= sin x + cos² x / sin x
= (sin² x + cos² x ) / sin x
Using the trigonometric identity that sin² x + cos² x = 1, we get that:
= 1 / sin x
= cosec x
Therefore after simplifying the expression sinx + cotx cosx, we get the result as cosec x.

On the last three physics exams a student scored 85, 87, and 91. What score must the student earn on the next exam to have an average of at
Least 90?
If you want to have an average of at least 90, the score that you need to get in the last exam is at least 97 points.
What score must the student earn on the next exam to have an average of at least 90?
We know that the scores on the first 3 exams are 85, 87, and 91.
If the score in the fourth exam is x, then the average of the 4 exams will be:
(85 + 87 + 91 + x)/4
If we want to have an average of at least 90, then we need to solve:
(85 + 87 + 91 + x)/4 = 90
Solving that for x we will get:
(263 + x) = 90*4
x = 90*4 - 263 = 97
The score that you need to get in the last exam is 97 points.

There are 63 students going on the trip, and you want to divide them up between 15 chaperones with 4 or 5 students in each group. How many groups will have 4 students, and how many will have 5?
There are 12 groups with 4 students and 3 groups with 5 students
How many groups will have 4 students, and how many will have 5?Represent the students as follows:
Group with 4 students = x
Group with 5 students = y
So, we have the following system of equations
4x + 5y = 63
x + y = 15
Make x the subject in x + y = 15
x = 15 - y
Substitute x = 15 - y in 4x + 5y = 63
4(15 - y) + 5y = 63
Expand
60 - 4y + 5y = 63
Evaluate
y = 3
Substitute y = 3 in x = 15 - y
x = 15 - 3
This gives
x = 12
Hence, there are 12 groups with 4 students and 3 groups with 5 students

A. More unequal distribution of natural resources
B. Improved incomes for poor people in all countries
C. Decreased competition for small businesses
OD. Decreased demand for natural resources
The phrase that best relates to the term "Globalization" is "Improved incomes for poor people in all countries".
As per the question statement, we are provided with the term of "Globalization" and we are required to match it with the best possible phrase from the four options provided.
Option (A) is "More unequal distribution of natural resources" which is incorrect because unequal distribution does not depend on globalization but on the size of the company and their effects on the environment.
Option (C) is "Decreased competition for small businesses" which is incorrect because this will increase the competition for small business.
Option (D) is "Decreased demand for natural resources" which is incorrect, since globalization speeds up the exchange of capital-labor production which requires more natural resources rather than their decrease.
Option (B) is "Improved incomes for poor people in all countries" which is the correct match, because globalization's main character is economic growth which directly affects the totally population of a country including the poor as the country becomes open to trade and then tends to work faster than the time when it was not open to trade, and this creates job opportunity for the people and helps in increasing the living standard of the people.
Hence, the best possible match to the term "Globalization" is "Improved incomes for poor people in all countries".

Fractions represent parts of a whole or collection of objects. In the above question the value of x is equals to 9
What is a fraction?Fractions represent parts of a whole or collection of objects. A fraction has two parts. The number on the top of the line is called numerator. It tells how many equal parts of whole or collection are taken. The number below line is called denominator. It shows total number of equal parts the whole is divided into or the total number of the same objects in a collection.
When whole is divided into equal parts, the number of parts we take makes up a fraction.
In the mathematics, there are three major types of fractions. They are the proper fractions, improper fractions and mixed fractions. Fractions are those terms which have the numerator and denominator. Fractions are the terms used to determine parts of a whole object.
