find the estimated quotient.
1. 4234 devide 51
The estimated quotient of the division is 83.
In mathematics, a quotient is a quantity created by the division of two integers (from the Latin quotients, meaning "how many times").
The term "quotient" is used frequently in mathematics, and it can also refer to a fraction or a ratio as well as the integer portion of a division (in the case of Euclidean division)(in the case of proper division). For instance, the quotient in the sense of Euclidean division is "6 with a remainder of 2" when 20 (the dividend) is divided by 3 (the divisor).The most common way to represent the quotient is as two integers or two variables split by a horizontal line. The terms "dividend" and "divisor" relate to each component separately, whereas "quotient" describes the entire thing.Now let us divide 4234 by 51.
4234 ÷ 51 = 83.019...
Therefore the quotient is 83
4234 divided by 51 gives quotient 83 and remainder 1 .

Complete question is:
The function f(x) = 600 - 100x models the value, f(x), of a video game system x years after purchase. Which choice represents the most appropriate domain of the function?
Answer and explanation:
The domain of a function is the values you can plug into the function, the possible values for x.
While x could take any value, there are a range of apropiate values that it can take.
For example, since x represents years after purchase, x can not be a negative number, because that would represent negative years, thus x must be greater or equal to 0.

For this case our reference triangle is ABC and we want to describe what we need to do in order to obtain the triangle DEF

The true statement is g(-13)= 20.
What is domain and range?In mathematics, a function is represented as a rule that produces a distinct result for each input x. Mapping or transformation is used to denote a function in math. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
domain = -20 ≤ x ≤ 5
and a range = -5 ≤ g(x) ≤ 45
and g(0) = -2 and g(-9) = 6
First, g(-13)= 20
x=-13 is in our domain and 20 is also in our range .
So this is true for g(-13)= 20.
Now, g(-4) = -11
-11 does not comes under the range.
So this statement is not true.
Again, g(0) = 2 is false because g(0) = - 2.
and, g(7) = -1 D
7 is not in our domain .
So g(7) is not possible

Harry’s company can store 50,000 units of their new product in the warehouse, the maximum capacity for the warehouse. They sold 20,000 in pre-orders that will need to be shipped immediately. They can produce 3000 units per week, and they are receiving 1500 orders per week. How long will it take to fill the warehouse to maximum capacity based on the current production rate?
The company will take 47 weeks to fill the warehouse to its maximum capacity based on the current production rate.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Maximum capacity for the warehouse = 50,000 units
Pre-orders = 20,000 units
Number of units produced per week = 3000 units
Number of orders per week = 1500 units
The number of weeks to fill the warehouse to its maximum capacity:
We can make an equation as:
3000M - 1500M - 20,000 = 50,000 ____(1)
M = number of weeks
From (1) we get,
M ( 3000 - 1500 ) - 20,000 = 50,000 ____(2)
1500M - 20,000 = 50,000
1500M = 50,000 + 20,000
1500M = 70,000
M = 46.66 weeks
M = 47 weeks
We can also see that,
From (2),
M ( 3000 - 1500 ) - 20,000
47 x 1500 - 20,000
70,500 - 20,000
50,500
Thus,
The company will take 47 weeks to fill the warehouse to its maximum capacity based on the current production rate.

When riding his bike down a hill, Lance can maintain an average speed of 55.5 km/h. When riding uphill, his speed drops to an average of 24.25 km/h. On a recent ride, 28% of Lance's ride was uphill, 33% was downhill and the rest of the ride was on a mostly flat surface. If the distance he covers is 475 km, how long do you think he took to complete his ride? Show your work.
Answer:
10.59480821 hours
Step-by-step explanation:
First, we need to know the percent of the flat surface. so we are gonna add the uphill and down hill then take the sum and find the difference from 100% 28+33+x=10061+x=100[tex]\frac{61+x}{-61} =\frac{100}{-61}[/tex]x=392. Now we know the percent for each surface
Uphill = 28%Downhill = 33%Flat = 39%3. Now that we know the percent of each surface we need to find out how many km for each surface:
Uphill
0.28×475=133kmDownhill
0.33×475=153.75kmFlat
0.39×475=185.25km3. Now that we know all the percent and distance for each surface we need to know the km/h for each
Uphill = 24.25km/h
Downhill = x
Flat = 55.5km/h
4. Since we don't have the speed for downhill we need to know the difference between uphill and flat
55.5-24.25=31.255. Now we know the difference is 31.25 we can add that to the flat surface to get the downhill speed
55.5+31.25=86.75Downhill =86.75km6. Now we know all the speeds and now we can figure out how many hours it takes for each surface
( we are going to take the distance in 1 surface and then divide that by the km/h in that surface to ket how many hours)
Uphill
133÷24.25=5.484536082 hoursDownhill
153.75÷86.75=1.772334294 hoursFlat
185.25÷55.5=3.337837838 hours7. Now we add all the hours up
5.484536082+1.772334294+3.337837838= 10.59480821 hoursEASY) write and equation for x then solve for x

After solving basic fractions we have come to find that, we need 12.7 tiles to create a frieze above a Forrest.
What is fraction?When describing a portion or part of a whole in mathematics, a fraction is used. The equal components of the whole are represented by it. Both the numerator and denominator are components of a fraction.
Both the top and bottom numbers are referred to as the numerator and denominator, respectively. The denominator specifies the total number of equally sized pieces in the whole, whereas the numerator specifies the number of equal parts that were taken.
A fraction is something like 5/10.
The denominator in this case is 10, and the numerator is 5.
The measure of each tile = 2⅞
= 23/8
Measure of doorway = 36½

Given: A piecewise rectangular figure is given.
Required: To determine the area of the given figure.
Explanation: The area of the given figure can be determined by splitting the figure into two squares as shown below:
Now the figure is divided into a square with an edge of 3 cm and a rectangle of 8 cm by 5 cm.
And the area of the square is
[tex](edge)^2[/tex]And the area of a rectangle is the product of length by breadth.
Hence, the area of the figure is-

MATRECIES: Suppose ={u,v,w}⊆R3 is linearly independent. Determine if the set 4 ={u, v, v−w, u+v+w} is linearly independent or linearly dependent.
The set is linearly dependent.

[tex]c_1 u + c_2 v + c_3(v-w) + c_4(u+v+w) = 0[/tex]
or equivalently,
[tex](c_1 + c_4) u + (c_2 + c_3 + c_4) v + (-c_3 + c_4) w = 0[/tex]
which is the same as solving the system of equations
[tex]\begin{cases} c_1 + c_4 = 0 \\ c_2 + c_3 + c_4 = 0 \\ -c_3 + c_4 = 0 \end{cases}[/tex]
From the first and last equations, we have [tex]c_1=-c_4[/tex] and [tex]c_3=c_4[/tex]. Substituting these into the second equation leaves us with [tex]c_2-2c_1=0[/tex], and so the overall solution set is
