Carmen cuts a 60 inch long wire into pieces that are 3/4 inch long. How many pieces does she have?
Answers
= 60 ÷ 3/4
Keep the first number, change the sign, and flip the fraction.
= 60 × 4/3
You can reduce the numbers by the GCF (greatest common factor) of 3.
= 20 × 4/1
After reducing 60 to 20 and 3 to 1, you are left with 20 × 4/1 or simply 20 × 4.
Multiply the numbers as usual, and you will get your product of 80.
Carmen has 80 pieces.

Whiteboard markers cost $4.75 per set at an office supply store. Which equation can be used to determine the price, P, of n sets of these markers? P = 4.75n, n = 4.75P, P equals 4.75 over n, n equals 4.75 over P
Answers
The expression which represents the price of the n number of the set is p = 4.75n. The correct option is A.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

After 4 apples were added to a sack, there were 3 times as many apples in the sack as before. How many apples were in the sack before the addition?
Answers
So, your equation for this problem would be—
x+4=3x
To solve this equation, you need to move the variables (x) to only one side of the equation.
So, you would use the Subtraction Property of Equality.
x+4=3x
-x -x
—————
4=2x
Now, your new equation is 4=2x.
Using the Commutative Property, we can reverse this to—
2x=4
Your next step is to find X. To do this, we can divide each side by 2.
2x=4
———
2 2
____
2/2=1. 4/2=2
Thus your new equation is—
X=2.
As a conclusion, there were 2 apples in the sack before you added the extra ones.
To check this, you could do
2+4= 6
6/3= 2
There were 2 apples originally in the sack.

REASONING!
1. The sum of the four integers is (-6)
2. When you order the integers from LEAST to GREATEST the difference of the
middle two integers is (-4) and the sum is 0
3. The quotient when you divide the LEAST integer by the GREATEST is (-3)
4. The product of the two greatest integers is (+6)
Answers
The key is in conditions 2 & 3.
B-C=-4, and B+C=0
therefore B=-2, C=2 by solving the two previous equations.
Given that the product of the two greatest numbers is 6, we have C*D=6, or
D=6/C=6/2=3
Now since the sum of all the four numbers is -6, we have
A+B+C+D=-6
A-2+2+3=-6
A=-6+2-2-3=-9
Check: we were told smallest divided by greatest = A/D=-9/3=-3 ok.
So the numbers are
A=-9, B=-2, C=2, D=3.

What is the mean,median,mode(s) an range if the numbers are 15,30,17,15,24,31,15
Answers
Hello There!
Mean: Average of numbers in a set of data.
STEP 1: Add the numbers together. In this case, we would add
15 + 30 + 17 + 15 + 24 + 31 + 15 = 147
STEP 2: Divide the sum by the number of digits you added. We would divide
147 "sum of numbers" by 7 "number of digits" and we would get an answer of
21.
The mean for the set of data is 21
Median: The middle number when all the numbers are listed in order.
To find the median, we would put the lowest number on the left and the biggest number on the right and continue to go from least top greatest.
-Least To Greatest-
15-15-15-17-24-30-31
In our set of numbers, we cross out one number from the left and the right each time until we come across one number in the middle. The number that is in the middle in 17.
The median for this set of data is 17
Mode: The number that occurs most often in a set of numbers.
15-15-15-17-24-30-31
Since the number 15 occurs three times, the mode for the set of data is 15.
The mode for this set of data is 15
Range: The difference between the highest and the lowest number.
15-15-15-17-24-30-31
The highest number in the set of numbers is 31 and the lowest number in this set is 15.
31 - 15 = 16
The range for this set of data is 16

What is the Cartesian Product of two sets?The cartesian product of two sets A and B is a set containing ordered pairs (x, y), for every x ∈ A, and every y ∈ B.
How to solve the question?In the question, we are informed that Kelly is picking out an outfit to wear. The organized list below represents the sample space of all possible outfits.
Redshirt – Black pants
Redshirt – White pants
Pink shirt – Black pants
Pink shirt – White pants
We are asked to find the number of different color shirts Kelly has to choose from.
Assuming the sample space to be the Cartesian Product of the set of shirts and set of pants, we can write the set of shirts as the first element of every ordered pair to get:
Set of Shirts = {Redshirt, Redshirt, Pink Shirt, Pink Shirt}.
Removing the repeating terms, we get:
Set of Shirts = {Redshirt, Pink Shirt}.
Thus, the number of shirts Kelly has to choose from is 2, namely Redshirt and Pink shirt. Computed using the Cartesian Product of sets.

If (2x^2 - 5x + 7) is subtracted from (4x^2 + 2x - 11),
= (4x^2 + 2x-11) - (2x^2 - 5x + 7)
= 4x^2 + 2x - 11 - 2x^2 + 5x - 7

Aubrey and Charlie are driving to a city that is 120 mi from their house. They have already traveled 20 mi, and they are driving at a constant rate of 50 mi/h. Complete the function that models the distance they drive as a function of time. Then complete a reasonable domain for this situation.
Answers
120 = 20 + 50t
2. The minimum time would be 0 hours. The maximum time is when the total distance of 120 is fully covered.
t ≤ (120 - 20)/50
t ≤ 2 hours
Thus, the domain would be 0 < t ≤ 2.
The function that models the distance they drive as a function of time is 120 = 20 + 50t
The required domain must be within the range of 0 and 2 i.e. 0≤t≤2
The formula for calculating distance travelled is expressed as:
Distance = Speed × time
Given the following
Total distance = 120 miles
Distance already travelled = 20milesIf they are trying at a constant rate of 50mi/hr, the distance travelled at the time "t", this period will be 50t.The required function that models the distance is expressed as;
120 = 20 + 50t
Hence the function that models the distance they drive as a function of time is 120 = 20 + 50t
To get a reasonable domain, we need to get the value of t as shown;
120 = 20 + 50t
120 - 20 = 50t
100 = 50t
t = 100/50
t = 2sec
Hence the required domain must be within the range of 0 and 2 i.e. 0≤t≤2
