Put 38200 in standard Form
Answer: Thirty-eight thousand two hundred.
Step-by-step explanation: You'd get Thirty-eight thousand two hundred because the standard form is writing out the number using letters. So, we should break this down:
38,000 + 200 is a good strategy to divide big numbers.
So, 38,000 = Thirty-eight thousand
And 200 = two hundred
So, combine it and you get Thirty-eight thousand two hundred or Thirty-eight thousand and two hundred. (it's the same thing)

Answer:
x=20 degrees
Step-by-step explanation:
So, lets recall some things.
First off, opposite angles are the same.
So this would make x equal 20.
But lets test this.
When you look at a X, or any other sort of two lines that cross each other, can you ever think of a time when one side is not the same as the other? No.
This is because when you change one angle, since the lines are crossed together, it will change the opposite angle. This change will always be constant as long as the two lines connect at the same point
So if you changed a 10 degree angle of two lines, so that it was 30, this would change for the other line.
I attached a image below.
I hope this explains this to you and helps! :D
==================================================================
Respuesta:
x = 20 grados
Explicación paso a paso:
Entonces, recordemos algunas cosas.
En primer lugar, los ángulos opuestos son iguales.
Entonces esto haría que x sea igual a 20.
Pero probemos esto.
Cuando miras una X, o cualquier otro tipo de dos líneas que se cruzan, ¿puedes pensar alguna vez en un momento en el que un lado no sea igual que el otro? No.
Esto se debe a que cuando cambia un ángulo, dado que las líneas se cruzan, cambiará el ángulo opuesto. Este cambio siempre será constante siempre que las dos líneas se conecten en el mismo punto
Entonces, si cambia un ángulo de 10 grados de dos líneas, de modo que sea 30, esto cambiaría para la otra línea.

For which values of x does each expression make sense? square root of x-2 over square root of x-3
the answer is x>3
this is the answer becuase x-3 cannot be 0 because tou cant divide by zero and it cant be negative because it is in the square root notation which cant be negative without the use of inaginary numbers

Tom is adding soil to his raised garden bed. The depth of the soil is currently 8 inches, and for each bag of soil he adds, the depth will increase by 1/2 of an inch. You can use a function to describe the depth of the soil in the garden bed after Tom adds x bags of soil.
Write an equation for the function. If it is linear, write it in the form h(x)=mx+b. If it is exponential, write it in the form h(x)=a(b)^x.
The function that describes the depth of the soil is h(x) = -(1/2)x + 8.
Where x is the number of bags of soil.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Depth of the soil = 8 inches
One bag of soil increases by 1/2 of an inch.
Now,
The function denotes the depth of the soil.
h(x) = -(1/2)x + 8
Where x is the number of bags of soil
Thus,
The function is h(x) = -(1/2)x + 8.

if x+y+z=1 and 1/x+1/y+1/z=0
what is x²+y²+z²=?
A) 0
B) 1
C) 2
D) 3
Answer:
B
Step-by-step explanation:
Given
[tex]\frac{1}{x}[/tex] + [tex]\frac{1}{y}[/tex] + [tex]\frac{1}{z}[/tex] = 0 , then
[tex]\frac{yz+zx+xy}{xyz}[/tex] = 0 , so
yz + zx + xy = 0
Now
(x + y + z)² = x² + y² + z² + 2(xy + yz + zx) , that is

x² + y² + z² = 1
Find the volume of the right prism with a cylindrical hole. Round to the nearest tenth.
Answer:
11.2
Step-by-step explanation:
First, you get the volume of the right prism by multiplying the length times the width times the height, which is 2.5 cubed. Then we subtract the volume of the cylindrical hole. We do this by doing pi times the radius squared times the height, which is pi times 0.75 squared times the height. This will yield 11.2 cubic millimeters.

The measure of the angle of the shaded sector with an area of 65 cm² is 74.5°
What is an equation?An equation is used to show the relationship between numbers and variables.
The area of a two dimensional shape is the amount of space it occupies.
The area of a sector in a circle is given by:
Area = (Ф/360) * π * radius²
Where Ф is the sector angle
Given that sector area is 65 cm², radius is 10 cm, hence:
Area = (Ф/360) * π * radius²
Substituting gives:
65 = (Ф/360) * π * 10²
Ф = 74.5°
The measure of the angle is 74.5°

It takes 34 of an hour to paint a single shutter. It takes 9 hours to paint 12 pairs of shutters. The number of hours, y, that it takes to paint xshutters shows either a direct or inverse variation. What is the equation that relates x and y?
The equation that relates x and y for the given data is y = (3/4)x.
The relationship between the number of shutters (x) and the number of hours (y) is an inverse variation because as the number of shutters increases, the number of hours required to paint them decreases and vice versa.
An inverse variation is a relationship between two variables in which their product is always equal to a constant value. Mathematically, it can be represented by the equation: y = k/x where k is a constant and x and y are the variables in question.
Hence, the equation that relates x and y can be found using the information given:
y = (9 hours) / (12 shutters) * x shutters
y = (3/4)x is the required equation.

What is a reflection?In Mathematics, a reflection can be defined as a type of transformation which moves every point of the geometric figure by producing a flipped, but mirror image of the geometric figure.
In Geometry, a reflection across the y-axis (y = x) is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, a reflection over the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.
By reflecting the given function across the across the y-axis (y = x), we have the following:
f(x) = x/3 - 6
g(x) = f(-x)
g(x) = -x/3 - 6.

Find the constant a, P and Q such
that 3x²-12x+16=a(x+p) +q
Answer:
Step-by-step explanation:
Rewrite 3x²-12x+16 as follows:
3(x^2 - 4x) + 16
Complete the square of x^2 - 4x; it is (x - 2)^2 - 4. We then have:
3( (x - 2)^2 - 4) + 16, or:
3(x - 2)^2 - 12 + 16, or
3(x - 2)^2 + 4
Then a = 3, p = -2 and q = 4
********************************************************************
Completing the square of x^2 - 4x is done as follows:
1. Identify the coefficient of x: It is -4.
2. Take half of this result: It is -2
3. Square this, and then add the square to x^2 - 4x, and then subtract it:
x^2 - 4x = x^2 - 4x + 4 - 4
4. Rewrite this result in the form (x - a)^2 - c:
(x - 2)^2 - 4
5. Now follow the remainder of the problem solution (given above)

Given:
Lacy work 15 hours last week and she was paid $127.50.
To find:
The hourly pay of Lacy.
Solution:
We have,
15 hours pay = $127.50
To find the hourly pay of Lacy, we need to divide total pay by number of hours.

Gwen scans a photo that is 4inches wide by 6 inches long into her computer. If she scales the length down to 3inches how wide should the similar photo be?
The similar photo should be 4.5 inches wide.
What is scale factor?Direct variation of a quantity {y} with respect quantity {x} means that the value of {y} increases as the the value of {x} increases. Mathematically -
y = Kx
K = y/x
where -
{K} is scale factor. It also tells by how many times is {y} greater than {x}.
Given is that Gwen scans a photo that is 4 inches wide by 6 inches long into her computer. Now, she scales the length down to 3 inches.
We can write -
y₁/x₁ = y₂/x₂
6/4 = 3/x₂
x₂ = 6 x 3/4
x₂ = 6 x 0.75
x₂ = 4.5
Therefore, the similar photo should be 4.5 inches wide.

Question 1 options:

(-3,6)
(3,6)
(5,9)
Answer:
x=3,y=6
Step-by-step explanation:
2x−y=0
3x−2y=−3
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
2x−y=0,3x−2y=−3
To make 2x and 3x equal, multiply all terms on each side of the first equation by 3 and all terms on each side of the second by 2.
3×2x+3(−1)y=0,2×3x+2(−2)y=2(−3)
Simplify.
6x−3y=0,6x−4y=−6
Subtract 6x−4y=−6 from 6x−3y=0 by subtracting like terms on each side of the equal sign.
6x−6x−3y+4y=6
Add 6x to −6x. Terms 6x and −6x cancel out, leaving an equation with only one variable that can be solved.
−3y+4y=6
Add −3y to 4y.
y=6
Substitute 6 for y in 3x−2y=−3. Because the resulting equation contains only one variable, you can solve for x directly.
3x−2×6=−3
Multiply −2 times 6.
3x−12=−3
Add 12 to both sides of the equation.
3x=9
Divide both sides by 3.
x=3
The system is now solved.
x=3,y=6
