Since 5/6 is a repeating decimal, Miguel should convert the fraction 5/6 to a decimal and multiply decimals.
Please Help Me!
The correcting answer is - Since 5/6 is a repeating decimal, Miguel should convert the decimal -0.6 to a fraction and multiply the fractions.
What is a fraction?Fractions represent the parts of a whole or collection of objects.
A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.
Now the given mixed fraction is,
-0.6(5/6)
Now since 5/6 is a repeating decimal,
Therefore converting 0.6 into fraction, we get
0.6 = 6/10
Therefore, -0.6(5/6) = -(6/10)*(5/6)
Rearranging we get,
-0.6(5/6) = -(6/6)*(5/10)
⇒ -0.6(5/6) = -1*(5/10)
or, -0.6(5/6) = -(5/10)
simplifying 5/10 we get,
-0.6(5/6) = -(1/2)
Thus, the correcting answer is - Since 5/6 is a repeating decimal, Miguel should convert the decimal -0.6 to a fraction and multiply the fractions.

The basketball team sells packages of licorice for $5 per package and bags of
M&M's for $8 per bag. The team sells a total of 240 of both for a total of $1614.
Find the number of packages of licorice and bags of M&M's they sold.
Answer:
The basketball team sells packages of licorice=Rs.5 per packageM&M's for =Rs.8 per bag
Both team sells a total 240 of a total of Rs.1614
Now
The total of both =1614-240=1374
The basketball team sold 102 packages of licorice and 138 bags of M&M's.
Given that the packages of licorice sold for $5 per package and that of the bags of M&M's for $8 per bag.
The total selling was total of 240 of both for a total of $1614.
We need to find the number of packages of licorice and bags of M&M's were sold.
Let's assume that the number of packages of licorice sold is represented by the variable "L" and the number of bags of M&M's sold is represented by the variable "M."
From the given information, we have two pieces of information to form equations:
The total number of packages and bags sold: L + M = 240
The total revenue from selling these items: 5L + 8M = 1614
Now, we can solve these two equations simultaneously to find the values of L and M.
First, let's solve the first equation for one of the variables (let's solve for L):
L = 240 - M
Now, substitute this expression for L in the second equation:
5(240 - M) + 8M = 1614
Now, distribute the 5:
1200 - 5M + 8M = 1614
Combine the M terms:
3M = 1614 - 1200
3M = 414
Now, solve for M:
M = 414 / 3
M = 138
Now that we know the value of M, we can find the value of L using the first equation:
L = 240 - M
L = 240 - 138
L = 102
So, the basketball team sold 102 packages of licorice and 138 bags of M&M's.

101+102-103+104-105+106-…-199+200
Please answer asap!!! Will give brainliest!!!!
Answer:
252
Step-by-step explanation:
One way we could think about this problem is by grouping the numbers together into pairs: -103+104 would be a pair, -105+106 would be a pair and et cetera up to the pair -199+200.
As you can see, each of these pairs add to 1 (-103+104=1, -199+200=1 etc.), so to solve this problem we can simply find how many of these pairs there are and multiply the number by 1 since each pair will total to 1.
To find how many pairs there are we need to find the number of numbers between 103 and 200 (incl.) and divide it by 2.
200-103= 97 numbers, adding 1 to count the one we started with gives us 98 numbers between 103 and 200 (incl.).
98/2 = 49 pairs of numbers. Since each pair totals 1, 1x49 is the total sum of all these pairs of numbers.
Now we need to address the other two numbers. The sequence started with 101+102 before we looked at the remaining pairs, so to find the sum, we just need to add together 101+102+49.
101+102+49 = 252

the length of a retangle is 4 times its width. The rectangles width is 8 m. What is the are of the rectangle?
The rectangle's width is 8m and the length is 4 times the width, so the length = 4 x 8 = 32m
To calculate the area of a rectangle, we take the width and multiply it with the length
A = 32 x 8 = 256m2

Answer:
soln ,given,
midpoint of CD=M(-2,5)

The linear equation in terms of the variable R is determined as x = R/10.
Given data:
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
The given equation is:
R = x + 9x
First, let's combine the like terms on the right side of the equation:
R = 1x + 9x
R = 10x
Now, we want to solve for x. To isolate x, divide both sides of the equation by 10:
R/10 = x
So, the solution for x is:
x = R/10

Invent two situations that you think would result in distributions with similar measures of variability
Explain your reasoning.
The two situations are:
Situation 1: Test Scores in Two ClassesSituation 2: Monthly Rainfall in Two CitiesSituation 1: Test Scores in Two Classes
Suppose we have two classes, Class A and Class B, taking the same exam with the same difficulty level.
The students in Class A are known to have a consistent level of performance, with most students scoring around the class average. The students in Class B, on the other hand, have a wider range of performance, with some students performing significantly better or worse than the class average.
In this situation, both classes are taking the same exam, so the central tendency (mean) of the test scores in Class A and Class B might be similar. However, the variability (spread) of the test scores in Class B is higher due to the wider range of performance among the students.
Situation 2: Monthly Rainfall in Two Cities
Consider two cities, City X and City Y, located in the same region. They experience a similar climate and weather patterns.
Over the course of a year, both cities receive roughly the same amount of rainfall on average. However, City X experiences more consistent monthly rainfall, with each month receiving rainfall close to the yearly average. In contrast, City Y has more variable monthly rainfall, with some months experiencing much higher or lower rainfall than the yearly average.
In this situation, the central tendency (mean) of the monthly rainfall in both cities will be similar since they receive the same average rainfall over the year.

What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.Given expression is 1/2 (-14m+ 4 )
To simplify this expression 1/2 (-14m+ 4 ) we get equivalent expression.
Multiply and Divide the expression by two.
⇒ -14m/2 + 4/2
To simplify the expression again, we get,
⇒ -7 m - 2

A transformation is the movement of a figure. There are four types of transformations: reflection, rotation, translation, and dilation. Of these four types of transformations, a transformation can either be a congruent or similar shape to the original image. Congruent means that the shape or figure retains its size, shape, length, and angles of the original shape.
A rotation is a turn around a centre point. In a rotation, the distance from each point on the shape to the centre remains the same. A rotation is identified by a shape turning a specific amount degrees, usually 90, 180, or 270 degrees, around a point either clockwise or counter clockwise. This means with each rotation performed four things are given.

Once someone has caught the virus, they do not catch it again.
The town has a fixed population of 700000

How many days does it take to make everyone in the town catch the virus?
Using an exponential function, it is found that it takes 20 days for everyone in the town to catch the virus.
What is an exponential function?An exponential function is given as follows:
[tex]y = ab^x[/tex]
In which:
a is the initial value.b is the rate of change.For this problem, we have that:
On the first day, one person has the virus.On the second day, the first person transmitted the virus to another person, hence two people have the virus.On the third day, each of the two people transmitted the virus to another two, hence four people have the virus.From this, we get that the parameters are given as follows:
a = 1, b = 2.
Hence the function for the number of contaminated people after t days is given by:
[tex]f(t) = 2^t[/tex]
Now, we have to solve for t when f(t) = 700000, hence:
[tex]2^t = 700000[/tex]
[tex]\log{2^t} = \log{700000}[/tex]
[tex]t\log{2} = \log{700000}[/tex]
t = log(700000)/log(2)
