At the end of the day of teaching the skill of cutting and sewing to make capes, Ms. Ironperson and Mr. Thoro decided to go to the Shawarma Mediterranean Grill. Ms. Ironperson ordered 3 chicken shawarma wraps and 2 orders of spiced potatoes for a total bill of $42.95. Mr. Thoro ordered 5 chicken shawarma wraps and 4 orders of spiced potatoes for a total bill of $74.91. What is the cost of a chicken shawarma wrap? What is the cost of one order of spiced potatoes? If x denotes the cost of a chicken shawarma wrap and y denotes the cost of an order of spiced potatoes, what are the equations needed to solve this problem?
Answer:
The cost of a chicken shawarma wrap = $10.99
The cost of an order of spiced potatoes=$4.99
Equations needed
3x+2y =42.95
5x + 4y=74.91
Step-by-step explanation:
x = the cost of a chicken shawarma wrap
y = the cost of an order of spiced potatoes
Ms. Ironperson
3x+2y =42.95
Mr. Thoro
5x + 4y=74.91
3x+2y =42.95 (1)
5x + 4y=74.91 (2)
Multiply (1) by 2
6x + 4y=85.9 (3)
5x + 4y=74.91. (2)
Subtract (2) from (3)
6x - 5x= 85.9 - 74.91
x=$10.99
Substitute the value of x into (1)
3x+2y =42.95 (1)
3(10.99) + 2y =42.95
32.97 + 2y = 42.95
2y = 42.95 - 32.97
2y=9.98
Divide both sides by 2
y=9.98/2
=4.99
y=$4.99
Therefore,
The cost of a chicken shawarma wrap = $10.99
The cost of an order of spiced potatoes=$4.99

Step-by-step explanation:
a companys product development division has 60 employees. Of these, 1/3 are engineers. If 40% of engineers are moved to another division. How many engineers will remain in the product development department?
Answer: There will be 12 engineers remaining in the product development department.
Step-by-step explanation:
So the givens are:
60 employees and 1/3 are engineers and if 40% of engineers are moved to another division and how many engineers will remain in the product development department?
So what we need to do:
60 * 1/3 = 60 / 3 = 20
There are 20 engineers.
20 * 40% = 8
There are 8 engineers that are going to be moved to another division.
20 - 8 = 12
12 engineers will remain in the development department.
Hence, your answer.
By calculations, 12 engineers will remain in the development department.
A companys product development division has 60 employees. Of these, [tex]\frac{1}{3}[/tex] are engineers.
The third part of a number is obtained by dividing a number by three, or what is the same, multiplying by a third ([tex]\frac{1}{3}[/tex]), thus dividing the number into a total of three equal parts.
In this case:
[tex]\frac{1}{3}[/tex]×60= 20
So, a companys product development division has 20 engineers.
40% of engineers are moved to another division.
The percentage is a way of referring to a proportion taking the number 100 as a reference. To calculate the percentage of a quantity, the quantity is multiplied by the percentage and divided by 100.
In this case:
40% of engineers= 40%×20=[tex]\frac{40x20}{100}[/tex]= 8
8 engineers are moved to another division.
The number of engineers who remain in the department is calculated by subtracting the total number of engineers in the department and the number of engineers who move to another division:
20 - 8= 12
12 engineers will remain in the development department.

Find the greatest number of 5 digits which
when divided by 25, 30 and 40 leaves a
remainder 20,25, and 35 respectively.
Answer:
99,595
Step-by-step explanation:
We are looking at division and remainders. What do you do when a remainder is present? You usually add it when multiplying to get the final number, but since we are doing this backwards, we have to subtract the numbers divided by the remainder.
25 - 20 = 5
30 - 25 = 5
40 - 35 = 5
Look for the LCM (Least Common Multiple) for 20, 30, and 40 :
600
Now for the equation :
n + 5 = Multiple of all numbers and LCM =
n + 5 = 166 * 600 = 99,600
n = 99,600 - 5 = 99,595
The greatest 5 digit number which when divided by 25, 30 and 40 has a remainder of 20, 25, and 35 is 99,595
The reason why the above value arrived at is correct is as follows:
The required parameter;
To find a 5 digit number that with remainder of 20, remainder of 25 and a remainder of 35, when divided by 25, 30, and 40 respectively
Strategy;
Find the LCM of the divisor, then find the highest common multiple of the
LCM that is a 5 digit number, equate the expression for the required 5 digit
number to the highest common multiple of LCM of the divisors by adding
a value that will give a factor of the divisor as follows;
Let x represent the 5 digit number, from the question, we get;
x = 25·a + 20
x = 30·b + 25
x = 40·c + 35
x < 99,999
The 5 digit number is not a multiple of 25, 30, and 40, therefore, the number is not a multiple of the LCM of 25, 30, and 40 which is 600
The highest multiple of 600 which is a 5 digit number = 99,600
Therefore, we can write;
25·a + 20 + 5 = 30·b + 25 + 5 = 40·c + 35 + 5 = 99,600
However;
25·a + 20 + 5 = x + 5
By transitive property, we get
x + 5 = 99,600
∴ x = 99,600 - 5 = 99,595
The 5 digit number, x = 99,595

Land in downtown Columbia is valued at $10 a square foot. What is the value of a triangular lot with sides of lengths 119, 147, and 190 ft?
Answer:
$87,461
Step-by-step explanation:
Given that the dimensions or sides of lengths of the triangle are 119, 147, and 190 ft
where S is the semi perimeter of the triangle, that is, s = (a + b + c)/2.
S = (119 + 147 + 190) / 2 = 456/ 2 = 228
Using Heron's formula which gives the area in terms of the three sides of the triangle
= √s(s – a)(s – b)(s – c)
Therefore we have = √228 (228 - 119)(228 - 147)(228 - 190)
=> √228 (109)(81)(38)
= √228(335502)
=√76494456
= 8746.1109071 * $10
= 87461.109071
≈$87,461
Hence, the value of a triangular lot with sides of lengths 119, 147, and 190 ft is $87,461.

Answer:
x - 6 = 0
Step-by-step explanation:
The only lines that have undefined slopes are vertical lines. Vertical lines are found in the form x = c where c is a constant. With vertical lines, it doesn't matter what the y value is because x will always be c. In this case, c = 6 because the x-coordinate of (6, -1) is 6. Therefore, our equation is x = 6. In standard form, that would be x - 6 = 0.

hypothesis that there is a relationship between parents’ and children’s party identification. Would we be correct in inferring that such a relationship also exists in the population? Explain your answer. What is the probability that any relationship we found is due to pure chance?
Answer:
No
It could be purely due to chance.
Step-by-step explanation:
A population is defined as the whole group which has the same characteristics. For example a population of the college belongs to the same college . But a sample may be an element of a population.
So it is not necessary for a population to have the same characteristics as the sample.
But it is essential for the sample to have at least one same characteristics as the population.
So we would not be correct in inferring that such a relationship also exists in the population.
It is a hypothesis which can be true or false due to certain conditions or limitations as the case maybe.
For example in a population of smokers some may be in the habit of taking cocaine. But a sample of cocaine users does not mean the whole population uses it.
It could be purely due to chance if we find out that there is a relationship between parents’ and children’s party identification in the population.

Which equation best represents the relationship?
Answer:
The equation that best represents the relationship is [tex]y=\frac{1}{2}x+2[/tex].
Step-by-step explanation:
We are given the following table representing the two quantities below;
x y
2 3
4 4
6 5
8 6
Firstly, we will find the two-point slope here, that is;
Consider two points; ([tex]x_1,y_1[/tex]) = (2, 3) and ([tex]x_2,y_2[/tex]) = (4,4)
Now, the formula for finding slope is;
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{4-3}{4-2}[/tex] = [tex]\frac{1}{2}[/tex]
Similarly, finding the slope for the points (6,5) and (8,6);
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{6-5}{8-6}[/tex] = [tex]\frac{1}{2}[/tex]
Now, the linear equation of the line having slope is given by;
[tex]y-y_1=m\times (x-x_1)[/tex] ; where m = slope and consider ([tex]x_1,y_1[/tex]) = (2, 3)
So, the equation of the line is;
[tex]y-3=\frac{1}{2} \times (x-2)[/tex]
[tex]y-3=\frac{1}{2}x-1[/tex]
[tex]y=\frac{1}{2}x+2[/tex]
Hence, the equation that best represents the relationship is [tex]y=\frac{1}{2}x+2[/tex].
Answer:
y = -1/2x + 11
1) write the equation of the
line in slope intercept form
that passes through (0,-2)
and (2,1).
Answer:
y=3/2x-2
Step-by-step explanation:
Find the slope first:
[tex]m=\frac{y_{2-y_{1} } }{x_{2}-x_{1} } =\frac{1-(-2)}{2-0}=\frac{3}{2}[/tex]
Then solve for y-intercept:
[tex]y=\frac{3}{2}x+b\\-2=\frac{3}{2}(0)+b\\-2=b[/tex]
Now, write out your complete equation:
y=3/2x-2
