Find an expression equivalent to 18 +30.
Factors of 18: 1, 2, 3, 6, 9, 18
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
18+30=6(3+10)
Answers
Answer:6 times 10 is not 30 it is 60 the and should be 18+30=3(6+10)
Step-by-step explanation:
The factor that multiplies with 6 to get 18 is 3 but the factor that multiplies with 6 to get 30 is 5.
The numbers in parenthesis should be a 5 and not a 10.
18 + 30 = 6(3 + 5)

For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.

Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)

In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.

We also have these reductions
Q to SR to PThis is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Answers
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

Answer:
what is a quartile?
Step-by-step explanation:
Answer:
The interquartile range is Q3 minus Q1, so IQR = 6.5 - 3.5 = 3.
Step-by-step explanation:
consider the following numbers: 1, 3, 4, 5, 5, 6, 7, 11. Q1 is the middle value in the first half of the data set. Since there is an even number of data points in the first half of the data set, the middle value is the average of the two middle values; that is, Q1 = (3 + 4)/2 or Q1 = 3.5. Q3 is the middle value in the second half of the data set. Again, since the second half of the data set has an even number of observations, the middle value is the average of the two middle values; that is, Q3 = (6 + 7)/2 or Q3 = 6.5.

A tart contains either 3 white, or 4 red, or 5 black cherries. A tray of 20 tarts contains 89 cherries. How many red cherries are on the tray if it contains 3 tarts with white cherries?
Answers
- x be the number of tarts with white cherries
- y be the number of tarts with red cherries
- z be the number of tarts with black cherries
From the problem, we know that each tart can only have one type of cherry. So we can set up the following system of equations:
x + y + z = 20 (the total number of tarts is 20)
3x + 4y + 5z = 89 (the total number of cherries is 89)
We also know from the problem that each tart with white cherries contains 3 cherries. So the total number of white cherries is 3x. We are looking for the number of red cherries, which is 4y.
To solve for y, we can use substitution. We can rearrange the first equation to get:
z = 20 - x - y
Then we substitute this expression for z in the second equation:
3x + 4y + 5(20 - x - y) = 89
Simplifying this equation, we get:
2x - y = -3
Now we can solve for y by isolating it on one side of the equation:
y = 2x + 3
We know that each tart with white cherries contains 3 cherries, so the total number of white cherries is 3x. We also know that each tart with black cherries contains 5 cherries, so the total number of black cherries is 5z. So we can rewrite the equation for the total number of cherries as:
3x + 4y + 5(20 - x - y) = 89
Simplifying this equation, we get:
2x - y = -3
Now we can solve for y by isolating it on one side of the equation:
y = 2x + 3
We know that each tart with white cherries contains 3 cherries, so the total number of white cherries is 3x. We also know that each tart with black cherries contains 5 cherries, so the total number of black cherries is 5z. So we can rewrite the equation for the total number of cherries as:
3x + 4y + 5(20 - x - y) = 89
Simplifying this equation, we get:

The height of a desk is 11 inches shorter than the height of a chair. The height of the chair is 41 inches.
Write an equation to find the height of the desk.
What is the height of the desk?
Answers
Answer:
equation: y=41-11
answer: the desk is 30 inches.
Step-by-step explanation:
So if the desk is 11 inches SHORTER than the chair, and the height of the chair is 41 inches, all you need to do is subtract 11 from 41, which will give you a total of 30 inches.
Hope this helps!
The required equation to find the height of the chair x is x + 11 = 41.
The height of the desk is 30 inches.
What is a linear equation?A linear equation is a relation between two expressions used to determine the value of an unknown variable.
How do we solve the given question?Let the height of the desk be x inches.
We are said that the height of the desk is 11 inches shorter than the height of the chair.
∴ Height of the chair = 11 inches + the height of the desk
or, Height of the chair = 11 + x.
We are said that the height of the chair is 41 inches.
We now equate the computed height and the given height of the chair to get the required equation,
x + 11 = 41.
∴ The required equation to find the height of the chair x is,
x + 11 = 41.
To find the height of the desk, we subtract 11 from both sides of the equation, to get:
x + 11 - 11 = 41 -11
or, x = 30
∴ The height of the desk is 30 inches.

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15
