The Central Islip community has 9,649 homes in it. Smart Boards cost the school district $5,200 each. The HS needs 175, the Reed School needs 150 and the Mulligan school needs 50 new boards. Network Outsource the schools tech company has 12 workers for the HS, 8 for the Reed School and 4 for Mulligan. They all work 8 hours a day. They work 5 days a week, Monday thru Friday. They earn $58 per hour. It will take 45 weeks to finish the job. Find: a) Total Product Cost b) Total Labor Cost c) Total Cost d) Cost per Home e) Cost per Week
Using proportions, the costs are given as follows:
a) Total Labor Cost: $2,505,600.
b) Total Product Cost: $1,950,000.
c) Total Cost = $4,455,600.
d) Cost per home = $461.77.
e) Cost per week = $99,013.33.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For item a, the labor cost is found using the earnings of the workers, as follows:
45 weeks x 5 days x 8 hours x 58 per hour x (12 + 8 + 4 workers)
Hence:
Total Labor Cost = 45 x 5 x 8 x 58 x 24 = $2,505,600.
For item b, the product cost is the cost of the boards, hence:
(175 + 150 + 50 boards) x 5,200
Total Product Cost = 375 x 5,200 = $1,950,000.
For item c, the total cost is the sum of the product cost and the labor cost, hence:
Total Cost = 2,505,600 + 1,950,000 = $4,455,600.
For item d, the cost per home is found dividing the total cost by the 9,649 homes, hence:
Cost per home = 4455600/9649 = $461.77.
For item e, the cost per week is found dividing the total cost by the 45 weeks, hence:
Cost per week = 4455600/45 = $99,013.33.

Name the type of triangle formed by the points P(2, 5), Q(4, 2) and R(7, 4).
The triangle formed by joining three points on the graph is isosceles triangle
To find out the type we need to find the length of each side which can be found out with distance formula =√[tex](x2-x1)^{2}[/tex]+[tex](y2-y1)\^{2}[/tex] ) provided in the coordinate geometry
so, the length of side PQ of triangle PQR = √[tex](4-2)^{2}[/tex])+[tex](2-5) ^{2}[/tex])
= √[tex]2^{2}[/tex] +[tex](-3)^{2}[/tex]
= √4+9
= √13 units
So, the length of side QR of triangle PQR = √[tex](7-4)^{2}[/tex]+[tex](4-2)^{2}[/tex] )
= √[tex]3^{2}[/tex] + [tex]2^{2}[/tex]
= √(9+4)
= √13 units
So, the length of side PR of triangle PQR = √([tex](7-2)^{2}[/tex]+[tex](4-5)^{2}[/tex] )
= √([tex]5^{2}[/tex] + [tex](-1)^{2}[/tex] )
= √(25+1)
= √26 units
As the two sides of triangle are equal so this triangle formed by joining three points on the graph is isosceles triangle

Find the coordinates of the orthocenter of ΔA B C with vertices A(-3,3), B(-1,7) , and C(3,3)
The orthocenter of the ΔABC is ( -1,5 ).
What is orthocenter?In a right triangle, the orthocenter is the polygonal vertex of the right angle. When the triangle's vertices and orthocenter are joined, any point becomes the orthocenter of the other three points, according to Carnot (Wells 1991). These four locations thus form an orthocentric system.
Given the co-ordinates A( -3,3 ), B( -1,7 ) and C( 3,3 ).
To find the orthocenter using below steps:
1. First, we find the equations of AB and BC.
The general form of a line is y = mx + b
where m is the slope and b is the y-intercept.
Using the formula of slope given [tex]$m =\frac{y_2 - y_1}{x_2 - x_1}[/tex] , we will find the slope of AB and BC.
Now, slope of AB is m = (7-3/-1 + 3)
i.e. m = (4/2) = 2
Putting this 'm' in the general form and using the point B(-1, 1), we get the y-intercept as,
y = mx + b
1 = 2 × (-1) + b
i.e. b = 3.
So, the equation of AB is y = 2x + 3.
Also, slope of BC is m=(3-7/3+1) i.e. m=-4/4 i.e. m--1
Putting this 'm' in the general form and using the point B( -1,1 ), we get the y-intercept as,
y = mx + b i.e. 1 = (-1) × (-1) + b i.e. b = 0.
So, the equation of BC is y = -x.
2. We will find the slope of line perpendicular to AB and BC.
When two lines are perpendicular, then the product of their slopes is -1.
So, slope of line perpendicular to AB is [tex]m*2=-1[/tex] i.e. m = -1/2
So, slope of line perpendicular to BC is i.e.[tex]m*-1=-1[/tex] i.e. m = 1.
3. We will now find the equations of line perpendicular to AB and BC.
Using the slope of line perpendicular to AB m=-1/2 i.e. and the point opposite to AB
i.e. C(3, 3), we get,
y = mx + b
i.e. [tex]3=-1/2*3+b[/tex]
i.e. b = 9/2
So, the equation of line perpendicular to AB is
[tex]y=-x/2+9/2[/tex]
Again, using the slope of line perpendicular to BC i.e. m = 1 and the point opposite to BC
i.e. A( -3,3 ), we get,
y = mx + b
i.e. 3 = 1 × -3 + b
i.e. b = 6.
So, the equation of line perpendicular to BC is y = x+6
4. Finally, we will solve the obtained equations to find the value of (x, y).
As, we have y = x + 6 and y = -x/2 + 9/2
This gives, y = -x/2 + 9/2 → x + 6
y = -x/2 + 9/2
simplifying the above equation, we get
2x + 12 = -x + 9
3x = -3
x = -1.
So, y = x + 6
simplifying the above equation, we get
y = -1 + 6
y = 5.
The value of x = -1 and y = 5.
Hence, the orthocenter of the ΔABC is ( -1,5 ).

The slope is -A/B and y-intercept is C/B in the line (A/D)x + (B/D)y = C/D
What is a slope of line?A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.
The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.
Therefore,
m = y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.
Be aware that tan ∅ = y/x.
We also refer to this tan as the line's slope
We know that the equation for slope(m) and y - intercept(c) of a line is given by :
y = mx + c
Here the equation is give as (A/D)x + (B/D)y = C/D, lets simply
⇒ (A/D)x + (B/D)y = C/D
⇒ B(y)/D = C/D -(A/D)x

If SU = 16.2 centimeters, what is RT ?
The diameter of a circle is defined as being twice the length of its radius.
If SU = 16.2 centimeters then the value of RT = 8.1 cm.
What is the difference between the radius and diameter of a circle?The diameter of a circle is defined as being twice the length of its radius. The radius of a circle is measured from the center to one of the circle's endpoints, whereas the diameter is measured from one end of the circle to another end of the circle, passing through the center.
In geometry, a circle's diameter is any straight line segment that passes through the center of the circle and has endpoints on the circle. It is also referred to as the circle's longest chord. Both definitions apply to a sphere's diameter.
The diameter is twice the radius because the greatest distance between two points on a circle must be a line segment through the center of the circle.
Here, SU is the diameter and RT is the radius.
Radius of the circle = 1/2 d
Where d = 16.2 then
substitute the value of d in the above equation, and we get
Radius of the circle = 1/2 (16.2)
Radius of the circle = 8.1
Therefore, the value of RT = 8.1 cm.

Answer:
Total Money = $ 75.00
Step-by-step explanation:
Let X be the Total Money
Amount Spent for Shopping = 2/3 of X = 2X/3
Money Lost = 3/5 of (X -2X/3) = 3/5 of (3X-2X)/3 = 3X/15 = X/5
Balance in hand = $ 10.00

With the aid of the line's slope and a point on the line, the equation of a line may be created. For a better understanding of how a line's equation is created, let's learn more about the line's slope and the necessary point on the line. The slope of a line is the angle that the line makes with the positive x-axis and can be stated as a numerical integer, fraction, or as the tangent of that angle. The term "point" refers to a coordinate system point with the x and y coordinates.
