For an amount of 6250 Peso, Hank have the quantities of the following denominations: 2503 bills of 50 peso, 2498 bills of 200 peso and 1249 bills of 500 peso.
How to apply systems of linear equations in real life equations
In this question we must translate the statement of the problem into mathematical expressions and then we must solve the resulting system. We need three equations that describe the quantities of 50 peso, 200 peso and 500 peso bills:
y = x - 5 (1)
0.5 · y = z (2)
x + y + z = 6250 (3)
The solution of the system of linear equations is described below:
x = 2503, y = 2498, z = 1249
For an amount of 6250 Peso, Hank have the quantities of the following denominations: 2503 bills of 50 peso, 2498 bills of 200 peso and 1249 bills of 500 peso. [tex]\blacksquare[/tex]

Circle K has an area of 80 cm^2. Circle M has a radius that is 2 times the radius of Circle K. What is the area of Circle M?
Answer:
Two shapes are similar when they have the same shape while their sizes may be the same or different
Therefore, two similar shapes are shapes that have a relationship such that the dimensions of one of the shapes can be obtained from the dimensions of the other shape by multiplying by a scale factor
All circles have the same shape and are defined by their center and radius
Given circle with center at 'x' and radius 'r' and circle with center 'y' and radius 's', then there exist a scale factor a = s/r such that we have;
r × a = s
Where a = s/r, we get;
r × s/r = s
We can therefore, obtain a circle with with the same size as the circle with center 'y' and radius 's' by multiplying the radius of the circle with center at 'x' and radius 'r' by a
Therefore the circle with center at 'x' and radius 'r' is similar to the circle with center 'y' and radius 's'Step-by-step explanation:

A particle moves along a hyperbola
xy = 12.
As it reaches the point (4, 3), the y-coordinate is decreasing at a rate of 3 cm/s. How fast is the x-coordinate of the point changing at that instant?
first off, let's notice that "x" and "y" are encapsulating a function in terms of time or namely "t", and that dy/dt is decreasing at a rate of 3 cm/s, since the rate is decreasing, that makes the rate negative, thus is changing at -3 cm/s.
[tex]xy=12\implies \stackrel{product~rule}{\cfrac{dx}{dt}y~~ + ~~ x\cfrac{dy}{dt}}~~ = ~~0\implies \cfrac{dx}{dt}y~~ + ~~x(-3)~~ = ~~0 \\\\\\ \cfrac{dx}{dt}y=3x\implies \left. \cfrac{dx}{dt}=\cfrac{3x}{y} \right|_{(\stackrel{x}{4},\stackrel{y}{3})}\implies \cfrac{3(4)}{3}\implies 4[/tex]

A regular hexagon is dilated by a scale factor of 4/3 to create a new hexagon. How does the perimeter of the new hexagon compare with the original perimeter?
oPTIONS:
The perimeter of the new hexagon is 4/3 the perimeter of the original hexagon.
The perimeter of the new hexagon is 12/3 the perimeter of the original hexagon.
The perimeter of the new hexagon is 16/3 the perimeter of the original hexagon.
The perimeter of the new hexagon is 16/9 the perimeter of the original hexagon.
Answer:
When a figure is dilated by a scale factor of a/b, then the new perimeter is a/b of the original perimeter and the new area is a 2 b 2 of the original area. Therefore, if the hexagon is dilated by a scale factor of , then the new perimeter is of the original perimeter.

Question 5. Bob Orleans invested $3,000 and borrowed $3,000 to purchase shares in Verizon Communications. At the time of his investment, Verizon was selling for $47 a share.
o If Bob paid a $30 commission, how many shares could he buy if he used only his own money and did not use margin?
o If Bob paid a $60 commission, how many shares could he buy if he used his $3,000 and borrowed $3,000 on margin to buy Verizon stock?
o Assume Bob did use margin and paid a $60 total commission to buy his Verizon stock. Also, assume he paid another $60 to sell his stock and sold the stock for $54 a share. How much profit did he make on his Verizon stock investment?
The number of shares could he buy is 63.19 and 126.38. Then the profit gained by Bob is $764.68.
What is the profit gained by Bob?
Bob Orleans invested $3,000 and borrowed $3,000 to purchase shares in Verizon Communications.
At the time of his investment, Verizon was selling for $47 a share.

Find the value of x. Round your answer to the nearest tenth
Answer:
13.8
Step-by-step explanation:
Let us use tan theta to find the value of x.
tan Θ = Opposite ÷ Adjacent
Given that,
Opposite ⇒ 12
Let us solve it now.
tan Θ = Opposite ÷ Adjacent
tan 41 = 12 ÷ x
0.8692 = 12 ÷ x
x = 12 ÷ 0.8692
x = 13.80
x ≈ 13.8

Answer:
1st Part: Infinitely many solutions
2nd Part: Exactly one solution
3rd Part: No Solutions
Step-by-step explanation:
First Part: 4(x - 1) = 4x - 4
Distribute. 4x - 4 = 4x - 4
Because the equations are the same, any value can be substituted for x and both the equations' values would still be equivalent.
2nd Part:
x + 4 = 4(x + 1)
x + 4 = 4x + 4
Minus 4 both sides
x = 4x
Only 0 can make this equation true, meaning it only has ONE solution.
Third Part:
4x + 1 = 4(x - 1)
Distribute.
4x + 1 = 4x - 1
Subtract 4x both sides
1 = -1
Obviously, 1 and -1 are not equivalent, meaning there are no value that can be substituted for x to make this equation true.

The cost for the contractor to have all the dirt hauled away for a foundation of 12 feet long, 9 feet wide and 6 feet deep is $720
Volume of rectangular prism
volume of a rectangular prism = lwh
where
l = lengthw = widthh = heightTherefore,
l = 12 ft
w = 9 ft
h = 6 ft
volume of the foundation = 12 × 9 × 6
volume of the foundation = 648 ft³
Therefore, the contractor pays $180 per load for the trucks remove the dirt.
648 cubic feet = 24 cubic yard
6 cubic yards = 1 truck load
24 cubic yard =

For simplicity I will substitue [tex]x[/tex] for β.
