In order to divide these numbers, first let's start with a 0 in the unit place, since 9.2 is smaller than 52.063.
Then, we multiply 9.2 by 10, this way we will calculate the tenths place.
Now, dividing 92 by 52.063, we have 1 as the result.
The remainder will be 92 - 52.063 = 39.937.
Again, let's multiply the remainder by 10, so now we will calculate the hundredths of the result.
Dividing 399.37 by 52.063 we have 7.
The remainder is 399.37 - 7*52.063 = 34.929.
Multiplying by 10, we have 349.29, and now we calculate the thousandths.
Dividing 349.29 by 52.063 we have 6.
Until now, the result of the division is 0.176.
Rounding to the nearest hundredth, we have 0.18 as the result of the division.

BD bisects ABC, m/ABD = 2(3x), and m/ABC = 42°.
What is the value of x?
In the given triangle ABC where BD bisects ABC and according to the values of the given angles, the value of x is found out to be 3.5.
It is given to us that -
BD bisects ABC.
m/ABD = 2(3x) ----- (1)
and, m/ABC = 42 ------- (2)
We need to find out the value of x.
Since BD bisects triangle ABC,
The angles created with respect to the bisector are equal.
=> m/ABD = m/CBD ----- (3)
Also, it is also known that -
m/ABD + m/CBD = m/ABC ----- (4)
Substituting equation (3) in equation (4),
m/ABD + m/CBD = m/ABC
=> m/ABD + m/ABD = m/ABC
=> 2 m/ABD = m/ABC ----- (5)
Substituting the values of m/ABD and m/ABC from equation (1) and (2) in equation (5), we get
2 m/ABD = m/ABC
=> 2*2(3x) = 42
=> 12x = 42
=> x = 3.5
Thus, according to the values of the angles of the triangle, the value of x is 3.5.

Answer:
A). 34%
B). 62%
Explanation:
Part A:
How many shoppers have an email account?
The answer is 32 + 2 = 34 shoppers have an email account.
What percent of the total shoppers are 34 shoppers?
We know the there are 100 shoppers in total ( 32 + 2 + 6 + 60 = 100); therefore, 34 shoppers is

Answer:
A
Step-by-step explanation:
First off we can see that there are 46 pencils - and 7 students - so we can divide the two
46/7 is not a whole number, so we need to find a number that can be multiplied by 7, and is right below 46.
If you multiply 7 by 6, you get 42, which is the highest you can get with multiply by 7, which is also below 46.
Now that we know that each student gets 6 pencils, we need to find out how many are left.
We can do 46 (total pencils) minus 42 (pencils given) to get a leftover of 4 pencils, so the answer is A.
the scatter plot below was constructed using data on length and inches (x) of several alligators and weight in pounds (y)right if you sent this describing the relationship between weight and length for these alligators
Answer
We are told that the relationship describing the weight and length, for alligators.
The length in inches is presented on the x-axis and the weight in pounds is presented on the y-axis.
The observations about this include
- From the scatterplot, we can see that the more the length of the alligator (that is, as x increases), the weight of the alligator also increases (that is, y increases too).
- This points to a direct relationship between the length of alligator and the weight of the alligator.
- Small alligators weigh light weights and longer alligators are heavy.

What is equation of line?
The algebraic form of representing set of points is known as the equation of line.
The point slope form is as follows:
[tex]y-y_{1}=m(x-x_{1})[/tex] ... (1)
Here, [tex]y_{1}[/tex] is [tex]y[/tex] co-ordinates, [tex]x_{1}[/tex] is [tex]x[/tex] co-ordinates, and [tex]m[/tex] is the slope.
Also, slope is given by the following expression:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Hence, equation (1) can be written as follows:
[tex]y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1})[/tex] ... (2)
Consider the following points:
[tex](g(x_{1}),x_{1})=(1250,0)\\(g(x_{2}),x_{2})=(750,5)[/tex]
substitute values in equation (2).
[tex]y-1250=\frac{750-1250}{5-0}(x-0)\\y-1250=-100x[/tex]
On comparing the above equation with equation (1), the value of slope [tex]m=-100[/tex]
Now, calculate the slope intercept form.
The following form is known as the slope intercept form:
[tex]y=mx+c[/tex]
Here, [tex]c[/tex] is the [tex]y[/tex] intercept that the value of [tex]y[/tex] when [tex]x=0[/tex] .
Substitute the value of slope that is -100 and value of g(x) when x =0 that is 1250 for [tex]c[/tex] in the above equation.
[tex]y=-100x+1250[/tex] ... (3)
Standered form of a line is as follows:
[tex]Ax+By=C[/tex]
Here, A,B, and C are integeres.
Rearrange equation (3) as follows:
[tex]y=-100x+1250\\100x+y=1250[/tex]
Hence, the point slope form is [tex]y-1250=-100x[/tex]. The slope intercept form is [tex]y=-100x+1250[/tex]. The standered form of line is [tex]100x+y=1250[/tex].

A driver accelerates her car from rest to a velocity of 35.9 mi/hr in 8.2 seconds. What is the acceleration of the car?
The acceleration of the car will be 0.002 m / s².
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The velocity of the car = 35.9 m/hr
The time take by car = 8.2 seconds
Now,
Since, We know that;
⇒ Acceleration = (Final velocity - Initial velocity) / Time
Since, The driver accelerates her car from rest to a velocity of 35.9 mi/hr.
So, Initial velocity = 0
And, Final velocity = 35.9 m / hr
= (35.9 / 3600) m/s
= 0.01 m / s
So, We get;
⇒ Acceleration = (Final velocity - Initial velocity) / Time
⇒ Acceleration = (0.01 - 0) / 8.2
⇒ Acceleration = 0.01 / 8.2
⇒ Acceleration = 0.002 m / s²
Thus, The acceleration of the car will be 0.002 m / s².

Type the correct answer in each box. Use numerals instead of words. This graph represents a quadratic function. What is the function’s equation written in factored form and in vertex form? Graph shows upward parabola plotted on a coordinate plane. The parabola has vertex at (2, minus 8) with the left slope at (0, 0) and the right slope at (4, 0).
The function’s equation written in factored form and in vertex form are respectively;
f(x) = 2x(x - 4)
f(x) = 2(x - 2)² - 8
How to Interpret Quadratic Graphs?The factored form of a quadratic function is;
f(x) = a(x - p)(x - q)
where:
p and q are the x-intercepts
a is a constant
Now, we are given x-intercepts as; (0, 0) and (4, 0)
Thus;
f(x) = a(x - 0)(x - 4)
f(x) = ax(x - 4)
To find a, substitute the given vertex (2, -8) into the equation and solve for a:
2a(2 - 4) = -8
-4a = -8
a = 2
Thus;
f(x) = 2x(x - 4)
The vertex form of a quadratic equation is;
f(x) = a(x - h)² + k
where:
(h, k) is the vertex
a is constant
Since vertex is (2, -8), then we have;
f(x) = a(x - 2)² - 8
Put the coordinate (0, 0) to find a;
0 = a(0 - 2)² - 8
4a = 8
a = 2
Thus;
f(x) = 2(x - 2)² - 8

Lina picks a 4 digit number.
The number is more than 5000.
The number is odd.
The second digit is a prime number.
How many different possible numbers could Lina pick?
Answer:
1000
Step-by-step explanation:
The easiest way to go about this is by turning our number into ABCD.
A will be in the 1000th spot, B 100th, C 10th, and D 1st.
A has to be ≥ 5. So 5, 6, 7, 8, 9.
B has to be a prime number. 2, 3, 5, 7.
C is able to be any number it wants, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Since the number is odd, D has to be 1, 3, 5, 7, 9.
A has 5 different possibilities. B has 4, C has 10, and D has 5.
You'll then multiply all of these numbers for your answer.
5 * 4 * 10 * 5 = 1000
