Two farmers pay a total rent of $140 for a pasture. The first farmer placed $4 oxen in the pasture, and the second farmer placed $30 sheep in the pasture. The farmers split the rent based on the proportion of the pasture eaten by their own animals that month. How much should the first farmer pay, if 1 ox eats as much as 10 sheep in a month?
given that 1 ox eats as much as 10 sheep:
4 oxen = 40 sheep
therefore,
first farmer: the equivalent of 40 sheep
second farmer: 30 sheep
that means 30+40 = 70 animals eating
$140 ÷ 70 = $2
so it is $2 per eat
2 x 40 = $80 for the first farmer's oxen
2 x 30 = $60 for the second farmer's sheep
Answer:
$80
Step-by-step explanation:
Since if 1 ox is equal to 10 sheep, then the first farmer posesses the equivalent of 40 sheep. With 70 sheep in total, then one sheep is worth 2 dollars. The first farmer has a total of 4 oxen, equivalent to 40 sheep. 40 times 2 is 80, so the answer is 80 dollars
A local coffee store is curious about the size beverages their customers are ordering. The beverages come in three sizes: small, medium, and large. An employee runs a simulation of 15 random outcomes using the values 1, 2, and 3 to represent small, medium, and large, respectively. What is the simulated probability that a customer will order the small beverage? 2 2 3 1 1 2 2 3 1 1 3 2 1 1 3
Answer:
2 out of 5 or 6 out of 15
Step-by-step explanation:
In this pattern, there is two people ordering it every five times. You can write it out as 6/15 or simplify it as 2/5 (six-fifteenths and two-fifths)
The simulated probability that a customer will order the small beverage is:
[tex]\dfrac{2}{5}=0.4[/tex]
Step-by-step explanation:The 1, 2, and 3 to represent small, medium, and large, respectively.
The simulation is as follows:
2 2 3 1 1 2 2 3 1 1 3 2 1 1 3
There are a total outcomes= 15
Also, the number of outcomes that the customer will order small beverage is: 6
( Since, 6 times such that 1 has occurred.
As 1 represent the simulation that the beverage comes in small size )
Hence, the simulated probability is:
[tex]\dfrac{6}{15}=\dfrac{2}{5}=0.4[/tex]
Triangle PQR is translated by the rule (x − 1, y − 1) and then dilated by a scale factor of 3 centered at the origin. Which statement describes the properties of triangles PQR and P''Q''R'' after the transformations? ∠P and ∠P'' are congruent after the translation, but not after the dilation. ∠P and ∠P'' are congruent after the dilation, but not after the translation. segment PQ and segment P double prime Q double prime are congruent after the translation, but not after the dilation. segment PQ and segment P double prime Q double prime are congruent after the dilation, but not after the translation
Answer:
segment PQ and segment P double prime Q double prime are congruent after the translation, but not after the dilation
Step-by-step explanation:
Translation and dilation have no effect on angles. All angles are congruent after either or both of translation and dilation.
Translation has no effect on size, so segments are congruent after translation. Dilation changes size, so segments are not congruent after dilation.
___
Comment on the problem wording
Ordinarily, the first transformation (translation) would result in figure P'Q'R', so P'Q' would be congruent to PQ. Then the second transformation (dilation) would change figure P'Q'R' to figure P''Q'' R'', which is no longer congruent to either figure P'Q'R' or figure PQR.
That is, talking about "segment P double prime Q double prime ... after the translation, but not the dilation" makes no sense, because there is no such segment. The segment that exists after the translation, but not the dilation, is segment P'Q'.
Answer:
line PQ and line P double prime Q double prime are congruent after the translation, but not after the dilation
Step-by-step explanation:
Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form.
−three fourthsx + y = 10
3x − 4y = −40
y = three fourthsx + 12
y = three fourthsx + 10
Answer:
[tex]3x-4y=-40[/tex]
Step-by-step explanation:
The standard form of a linear equation is [tex]ax+by=c[/tex].
The given line has equation:
[tex]y-4=\frac{3}{4}(x+8)[/tex]
This is the point-slope form of the given line.
To find the standard form, we clear the fraction
[tex]4y-16=3(x+8)[/tex]
We expand the parenthesis now to get:
[tex]4y-16=3x+24[/tex]
We group the variables on the LHS and the constants on the RHS.
[tex]4y-3x=24+16[/tex]
[tex]-3x+4y=40[/tex]
Multiply through by -1
[tex]3x-4y=-40[/tex]
This is of the form: [tex]ax+by=c[/tex].
Find the solution of this system of equations -2x=2+y , -6x-y=-2
Answer:
x = 1 and y = -4
Step-by-step explanation:
It is given that,
-2x = 2 + y
-2x - y = 2 ---(1)
-6x - y = -2 ----(2)
To find the solution of equations
Step 1: Subtract eq(2) from eq(1)
-2x - y = 2 ---(1)
-6x - y = -2 ----(2)
4x + 0 = 4
x = 4/4 = 1
Step 2: Substitute the value of x in eq (1)
-2x - y = 2 ---(1)
-2*1 - y = 2
-2 - y = 2
y = -2 - 2 = -4
Therefore x = 1 and y = -4

Which of these is not a typical application of investors money
Product improvement
Expansion
Employee salaries
Vacations
Vacations are not a typical application of investors' money as they do not contribute to future profitability or growth of a business, unlike product improvement, expansion, or employee salaries.
Explanation:The question asks about a typical application of investors' money which is not common. Of the options provided, vacations would not be a typical application of investor funds. Investors typically allocate capital to a business with the expectation of earning future profits.
Common expenses that may constitute investment in a firm include product improvement, expansion, and even employee salaries, as these are directly related to the operations and growth potential of the business.
Capital invested in the business is expected to generate future income and growth, through means such as buying long-term assets like machinery, building new plants, or initiating research and development projects. It's unlikely that investors would find vacations a viable investment category as it generally does not contribute to the future profitability or growth of a business enterprise.
Write the slope-intercept form of the equations
x=-3
and
x=5
Step-by-step explanation:
The slope-intercept form of an euqtion of a line:
y = mx + b
m - slope
b - y-intercept
x = a (a - any real number)
It's the equation of a vertical line. A vertical line has an undefined slope. They also do not have a y-intercept, because they run parallel to the y axis.
Therefore given equations can not write in the slope-intercept form.

Which rule describes the composition of transformations that maps ?DEF to ?D''E''F''? R0,90° ? T5,0(x, y) T–5,0 ? R0,90°(x, y) T5,0 ? R0,90°(x, y) R0,90°(x, y) ? T–5,0
Answer:
B. T–5,0 ∘ R0,90°(x, y)
Step-by-step explanation:
Just took Quiz.
Transformation involves changing the size and position of a shape.
The transformation rule from DEF to D"E"F is [tex]\mathbf{(b)\ T-5,0 \circ R0,90^o(x, y)}}[/tex]
From the complete question (see attachment), we have the following observations.
DEF is first rotated 90 degrees counterclockwiseThen translated to the left by 5 unitsThe 90 degrees counterclockwise rotation is represented as:
[tex]\mathbf{R0,90^o(x, y)}[/tex]
The left translation by 5 units is represented as:
[tex]\mathbf{T-5,0(x, y)}[/tex]
When both transformations are combined, we have:
[tex]\mathbf{T-5,0 \circ R0,90^o(x, y)}}[/tex]
Hence, the transformation rule from DEF to D"E"F is [tex]\mathbf{(b)\ T-5,0 \circ R0,90^o(x, y)}}[/tex]

Kira looked through online census information to determine the average number of people living in the homes in her city. What is true about Kira's data collection? Kira used an observational study where the data is qualitative. Kira used an observational study where the data is quantitative. Kira used published data that is qualitative. Kira used published data that is quantitative.
Answer:
Kira used published data that is quantitative
Step-by-step explanation:
Online census data is published data. It is numerical by nature, hence quantitative.
Answer:
Kira used published data that is quantitative.
Step-by-step explanation:
Firstly, we need to identify if the data is qualitative or quantitative.
The data is average number of people living in the homes.
Qualitative data as its name indicates is an attribute or characteristic. It can not be measured e.g color. Quantitative data is such a data which can be counted or measured.
Since the average number of people can be counted and measured, the data is Quantitative.
In an observational study the individuals are observed. In the given case, Kira did not observed the individuals to gather the data, rather she used an Online resource to gather the data.
Therefore, the correct answer will be:
Kira used published data that is quantitative.

Drawing five cards from a standard deck has how many possible outcomes and why?
Answer:
Step-by-step explanation:
Lots, even if you make this a combination problem. I'm going to treat it as a permutation first and then we'll look into a combination.
52 P 5 is the same thing as a counting problem
The first card drawn is 1 of 52
The second one drawn is 1 of 51
The third one drawn is 1 of 50
The 4th one drawn is 1 of 49
The 5 one drawn is 1 of 48
The answer you should get is 311 875 200
=====================
If your calculator does this then you should put in 52P5 and it will give you the possible outcomes. Remember the question asks you the number of outcomes not the probability.
=====================
The above number treats the order as different.
So 12345 is not the same as drawing 12354.
Those 2 sets of cards are counted as 2 not one.
I believe this to be the best answer.
======================
But if order does not matter, and you want 1 2 3 4 5 to be the same thing as 1 2 3 5 4 the problem is a combination problem. Ignoring the suits the answer is
52 C 5
which is 52 * 51 * 50 * 49 * 48 / 5! = 2598960
======================
I don't know how far into the course you are but the actual answer would have to account for the suits. This solution assumes that the actual card drawn remains upside down, that is, if it is the king of hearts, you don't know it.
