Answer:
Let x represent the amount that the supermarket paid for the box. We were told that the mark up was 20%. This mean that the amount, x was increased by 20%.
Recall, percentage is expressed in term of 100.
This mean that the amount by which it was increased is
20/100 * x = 0.2x
The selling price would be
x + 0.2x = 1.2x
If the supermarket sells the corn flakes for $3.6 per box, it means that
1.2x = 3.6
x = 3.6/1.2
x = 3
Thus, the amount that the supermarket paid for each box is $3

6. Gloves R’ Us was having a great day at their warehouse. Before lunch the store had sold a total of 82 pairs of gloves, and sales were brisk. At the end of the day, Dan, the owner, realized he just had the biggest day in Gloves R’ Us history with a total of 127 pairs of gloves sold. As he was heading back to restock for the next day, he asked his new employee, Mittsy, how many of each (cloth and rubber) they had sold. Poor Mittsy, being new, did not know that she was supposed to keep them separate. All she knew was that the rubber gloves were $8.95 each, the cloth gloves were $6.95 each, and the sales for the day totaled $1070.65. Help Mittsy keep her job by finding out how many of each type of glove was sold so Dan, the glove man, can restock.
Answer:
Step-by-step explanation:
c is the number of cloth gloves sold.
r is the number of cloth gloves sold.
c + r =127
c = 127 - r
6.95c + 8.95r = 1070.65
6.95(127 - r) + 8.95r = 1070.65
882.65 + 2r = 1070.65
r = 94
c = 33

On Thursday it snowed 3 ½ inches in 4 hours. On Friday it snowed 8 inches in 9 hours. On which day was it snowing faster?
Answer:
Friday
Step-by-step explanation:
Thursday 7/2 ÷ 4 = 7/8 inches an hour (.875)
Friday 8 ÷ 9 = 8/9 inches an hour (.888)
Friday it was snowing faster
Answer:
Friday
if Thursday snowed 3½ inch 4 hours
then for Friday
9 ÷ 8 = 1.125 inches for one hour
1.125 × 4 = 4.5 inches for 4 hours
1.25 inches more than Thursday. So, the answer is Friday ^^

1. x>17
2.x<17
3.x<_17
4.x>_17
Answer:
1. x > 17
Step-by-step explanation:
When the point on the graph is an open circle you are going to be using < or > as an open circle means greater than or less than
Immediately we can eliminate number 3 and 4
When the line is going in the direction of the right than the inequality sign will face the variable (x)
the numbers are getting larger meaning that x is greater than the constant (17)
Hence, your answer is x > 17
Extra notes:
when the point on the graph is a closed circle ( filled in ) then you will use ≤ or ≥ as a closed circle means greater than or equal to or less than or equal to

Ayden had a goal of finishing painting at least 80\%80%80, percent of the 500500500 square meters of a house's walls by today. He actually finished painting 415415415 square meters today. Did Ayden meet his goal? Why? , Ayden painted square meters than his goal.
Answer: Yes, [tex]15\ m^2[/tex]
Step-by-step explanation:
Given
The surface area of the house [tex]A=500\ m^2[/tex]
Ayden aims to finish 80% of the painting
The actual painting done by him is [tex]A_c=415\ m^2[/tex]
Now 80% of the total is
[tex]\Rightarrow A'=500\times \dfrac{80}{100}=400\ m^2[/tex]
Clearly, actual painting done is more than 80% of the painting
[tex]\therefore[/tex] Ayden meet his goal
[tex]\Rightarrow A_c-A'=415-400=15\ m^2[/tex]
He painted [tex]15\ m^2[/tex] more than his target

Step-by-step explanation:
An air-conditioning company counted 56 invoices at the end of the month. They charge $450 for a new installation and $75
for a service call. The total dollar amount of the invoices was $9,450.
How many installations and service calls did the company perform?
Answer:
14 installatons
42 service calls
Step-by-step explanation:
Let x = no. of new installations
y = no. of service calls
(1) x + y = 56 (2) 450x + 75y = 9450
y = 56 - x 450x + 75(56 - x) = 9450
450x + 4200 - 75x = 9450
375x = 5250
x = 14 installatons
y = 56 - 14 = 42 service calls
The number of installations are 14 and number of service calls are 42
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
An air-conditioning company counted 56 invoices at the end of the month.
For installation it charges $450 and $75 for a service call.
Let x be number of installations
y be number of service calls
x+y=56...(1)
and 450x+75y=9450..(2)
From equation 1
x=56-y
Now substitute x value in equation 2
450(56-y)+75y=9450
Apply distributive property
25200-450y+75y=9450
25200-375y=9450
Subtract 25200 from both sides
-375y=9450-25200
-375y=-15750
Divide both sides by 375
y=42
Now put y value in equation 1
x+42=56
x=14
Hence, the number of installations are 14 and number of service calls are 42

Find the perimeter RST. Round answer to the nearest tenth. Show all the work !!!
Given:
The figure of a triangle RST on a coordinate plane.
To find:
The perimeter of the triangle RST.
Solution:
From the given graph it is clear that the vertices of the given triangle are R(-2,7), S(-5,1) and T(-7,-5).
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, we get
[tex]RS=\sqrt{\left(-5-\left(-2\right)\right)^2+\left(1-7\right)^2}[/tex]
[tex]RS=\sqrt{\left(-5+2\right)^2+\left(1-7\right)^2}[/tex]
[tex]RS=\sqrt{\left(-3\right)^2+\left(-6\right)^2}[/tex]
on further simplification, we get
[tex]RS=\sqrt{9+36}[/tex]
[tex]RS=\sqrt{45}[/tex]
[tex]RS=3\sqrt{5}[/tex]
Similarly,
[tex]ST=\sqrt{\left(-7-\left(-5\right)\right)^2+\left(-5-1\right)^2}[/tex]
[tex]ST=2\sqrt{10}[/tex]
[tex]RT=\sqrt{\left(-7-\left(-2\right)\right)^2+\left(-5-7\right)^2}[/tex]
[tex]RT=13[/tex]
Now, the perimeter of the triangle RST is
[tex]Perimeter=RS+ST+RT[/tex]
[tex]Perimeter=3\sqrt{5}+2\sqrt{10}+13[/tex]
[tex]Perimeter=26.032759[/tex]
[tex]Perimeter\approx 26.0[/tex]
Therefore, the perimeter of the triangle RST is 26.0 units.
Given point P moving along a curve y = x²-1 and point Q moving along a line y = x-3. Find the coordinate of point Q and distance between P and Q that makes the distance between two points have minimum value. Show your work, thank you!
Answer:
Part A
The coordinates of point Q that makes the distance between the two points have minimum value is (9/8, -15/8)
Part B
The distance between P and Q at the closest point is approximately 1.287 units
Step-by-step explanation:
From the details given in the question, we have;
The curve along which point P is moving is, y = x² - 1
The (straight) line along which point Q is moving is, y = x - 3
The domain of the path of point P = All real numbers
The range of the path of point P = -1 < x ≤ ∞
The domain of the path of point Q = All real numbers
The range of the path of point Q = All real numbers
From the graph of the functions created with Microsoft Excel, we have that from point (0, 0) and moving to the positive x-axis, the slope of the path of P increases from 0 to ∞, while the slope of the path Q is constant and equal to 1
Given that the path of P is convex relative to the path of P, the two paths will be closest when they have equal slopes
Therefore at the closest point, for the path of point P, we have;
d(x² - 1)/dx = 1 (the slope of the path of point Q)
2·x = 1
∴ x = 1/2 on the path of point P at the closest point the path of point P to the path of point Q
∴ y = x² - 1 = (1/2)² - 1 = -3/4
y = -3/4
Given that two paths are parallel at the closest point, distance between the two paths is the perpendicular distance from the line y = x - 3 to the point (1/2, (-3/4)), which is given as follows;
∴ The slope of the line representing the perpendicular distance between the two paths = -1
Therefore, the equation of the line in point and slope form is given as follows;
y - (-3/4) = -1 × (x - 1/2)
y = -x + 1/2 - 3/4 = -x - 1/4
y = -x - 1/4
At the coordinates of point Q that makes the distance between the two points have minimum value, we have;
-x - 1/4 = x - 3
∴ 2·x = 3 - 3/4 = 2 1/4 = 9/4
x = 9/8
y = x - 3 = 9/8 - 3 = -15/8
Therefore, the coordinates of point Q that makes the distance between the two points have minimum value = (9/8, -15/8)
Part B
The formula for the length between two points is
[tex]l =\sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
The distance, d, between P and Q at the closest point is given as follows;
d = √(((9/8) - (1/2))² + ((-15/8) - (-3/4))²) = √(53/32) ≈ 1.287
The distance between P and Q at the closest point, d ≈ 1.287
