Converting Mexican pesos to US dollars, Kyle will get 2224 Mexican pesos for 200 US dollars.
In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.
A conversion factor is a number used to change one set of units to another, either by multiplying or dividing.
If 278 Mexican pesos is equivalent to 25 US dollars,
278 Mexican pesos = 25 US dollars
Dividing both sides by 25,
278/25 Mexican pesos = 25/25 US dollars
11.12 Mexican pesos = 1 US dollar
Therefore, 1 US dollar is equivalent to 11.12 Mexican pesos.
The conversion factor is 11.12 Mexican pesos/1 US dollar.
If Kyle wants to convert 200 US dollars to Mexican pesos for spending money, and 1 US dollar is equivalent to 11.12 Mexican pesos, multiply the amount by the conversion factor.
200 US dollars (11.12 Mexican pesos/1 US dollar)
= 2224 Mexican pesos

HELP Finding the initial amount and rate of change given a table for a linear function
The initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively
How to find the initial amount and rate of change given a table for a linear function?The table of linear function represents the given parameter
On the table, we have the following points
(x, y) = (6, 467) and (10, 647)
The rate of change is calculated as
Rate = (y2 - y1)/(x2 - x1)
So, we have
Rate = (647 - 467)/(10 - 2)
Evaluate
Rate = 22.5
This means that the rate of change is $22.5
The initial amount is calculated as
y = m(x - x1) + y1
Where
m = 22.5
So, we have
y = 22.5(x - x1) + y1
Using one of the points, we have
y = 22.5(x - 6) + 467
Set x = 0
So, we have
y = 22.5(0 - 6) + 467
Evaluate
y = 332
Hence, the initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively

The wavelength of the waves on a string that is vibrating at 220 MHz is 2.20 m. These waves move at a 4840 rpm rate as they move up and down the string.
What is a wave length?A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles. This length is typically defined in wireless systems in meters (m), centimeters (cm), or millimeters (mm) (mm). According to the available data, the wavelength is more frequently expressed in nanometers (nm), which are units of 10-9 m, or angstroms (), which are units of 10-10 m, for infrared (IR), visible light (VL), ultraviolet (UV), and gamma radiation ().

Under his cell phone plan, Logan pays a flat cost of $58 per month and $3 per gigabyte. He wants to keep his bill under $70 per month. Use the drop-down menu below to write an inequality representing gg, the number of gigabytes he can use while staying within his budget.
PLEASE HELPPPP 3
The inequality which can be used to determine the number of gigabytes is 58 + 3x < 70 and the solution is x < 4
How to write and solve an equation which can be used to determine the number of gigabytes?The given parameters are
Flat cost = $58
Rate = $3 per gigabyte
Budget = Under $70
The equation is represented as:
Total cost = Flat cost + Rate * Number of gigabyte
So, we have
y = 58 + 3x
The budget is under 70
So, we have
58 + 3x < 70
Subtract 58 from both sides
So, we have
3x < 12
Divide both sides by 3
So, we have
x < 4
Hence. the inequality which can be used to determine the number of gigabytes is 58 + 3x < 70 and the solution is x < 4

Lindsey is building a skateboard ramp. She wants the ramp to be 1 foot tall at the end and she wants it to make a 15^{\circ} angle with the ground. What length of board should she buy for the ramp itself? Round to the nearest foot.
The term "length" is used to describe an object's size or the separation between two points. Lindsey must buy 4 feet of the board for the ramp itself.
What is meant by length?The term "length" refers to the measurement or size of something from end to end. In other terms, it is the greater of the upper two or third dimension of a geometric shape or object.
Distance exists estimated in length. The length contain the dimension of distance in the International System of Quantities. The majority of measurement systems select a base unit for length from which all other units exists derived. The meter serves as the foundational unit of length in the International System of Units.
A rectangle, for instance, has length and width as its dimensions.
1/x = 15°
x = 1/sin 15°
simplifying the above equation, we get
x = 3.9ft
x ≈ 4 ft
Therefore, the value of x ≈ 4 ft.
Lindsey must buy 4 feet of the board for the ramp itself.

The other root of the given quadratic equation is a = ± 3/√2.
Given that, x=2 and x²+ax+12=0.
What are the roots of quadratic equations?The roots of a quadratic equation are the values of the variable that satisfy the equation. They are also known as the "solutions" or "zeros" of the quadratic equation.
Now, put x=2 in x²+ax+12=0 and find the value of a.
That is, 2²+2a+12=0
⇒4+12+2a=0
⇒16+2a=0
⇒2a=-16
⇒a=-8
So, the value of a is -8.
Put (0, 6) and (4, 6) in the function y=2x²+bx+c and find the value of b and c.
That is, 6=2(0)²+b(0)+c
⇒ c=6
6=2(4)²+b(4)+c
⇒ 6 = 32+4b+c
⇒ -26 = 4b + 6
⇒ 4b = -32
⇒ b = -8
So, the value of b is -8 and the value of c is 6.
Put x=a (root) in the equation 2x + x/a -9 = 0 and find the other root.
That is, 2a²+a/a -9 = 0
⇒ 2a² - 9 = 0
⇒ a²=9/2
⇒ a = ± 3/√2
Therefore, the other root of the given quadratic equation is a = ± 3/√2.
