Ron is paid $1,500 every month plus an additional $100 bonus for every tractor he sells, 2. Which equation represents the total amount of money, y, Ron makes each
month?
PLEASE ANSWER ASAP!
Answer: y= 100x +1500
Step-by-step explanation:
The 1500 value never changes, so it doesn’t need a variable
The 100 value will change based on how many he sells, so it needs a variable
Answer:
its the first one.
Step-by-step explanation:
the 1500 stays the same so it would be 100×how ever many tractors so 100z+1500
The _____ _____, denoted modifyingabove p with caret, is given by the formula modifyingabove p with caretequals_____, where x is the number of individuals with a specified characteristic in a sample of n individuals. the ▼ ▼ deviation mean proportion error variance , denoted modifyingabove p with caret, is given by the formula modifyingabove p with caretequals ▼ xn startfraction n over x endfraction startfraction x over n endfraction , where x is the number of individuals with a specified characteristic in a sample of n individuals.
Answer:
Sample proportion ; phat
x / n
Step-by-step explanation:
The sample proportion may be explained as a proportional representation of part of the population or larger sample which have a certain character or exhibit a particular trait.
The sample proportion is expressed Mathematically as ;
phat = x / n
x = number of subjects with a specified characteristic ;
n = total sample size
For instance ;
The proportion of black balls in a sample of 100 balls is 15 ; the sample proportion of bla k balls will be :
phat = x / n = 15 / 100 = 0.15
Quadrilateral ABCD has vertices A(- 3, 1), B(4, 2) B(4, 2), C(9, - 3) , and D(2, - 4) . aProve that quadrilateral ABCD is a rhombus b )Prove that ABCD is not a square .
9514 1404 393
Explanation:
The vectors representing the diagonals are ...
AC = C - A = (9, -3) -(-3, 1) = (12, -4)
BD = D - B = (2, -4) -(4, 2) = (-2, -6)
The dot-product of these vectors is the sum of the products of corresponding coordinates:
(12)(-2) +(-4)(-6) = -24 +24 = 0
When the dot-product is zero, the vectors are perpendicular. These vectors are different lengths (BD = 1/2·AC), so they are not the diagonals of a square.
__
The midpoints of the diagonals will be in the same place if the quadrilateral is a rhombus.
(A +C)/2 = (B +D)/2
We can simplify our effort a bit by multiplying by 2.
A+C = B+D
(9, -3) +(-3, 1) = (2, -4) +(4, 2)
(6, -2) = (6, -2) . . . . . . . . . . . . . . . . yes, the midpoints are the same point
__
We have shown the diagonals of the quadrilateral are different lengths and perpendicular bisectors of each other, so the quadrilateral IS A RHOMBUS, NOT A SQUARE.

A café has a monthly fixed cost of $4700, and a typical customer order costs the café $2. Therefore, the cost to serve x customers in a month is given by x = 4,700 + 2x. The typical order costs $10. So revenue is y = 10x. Find the number of customers that would need to come in the café for the company to break even. (Intersection point)
Answer:
The number of customers that would need to come in the café for the company to break even is 470.
Step-by-step explanation:
Given
Revenue = y = 10x ……………….…. (1)
Cost = x = 4,700 + 2x ……………… (2)
Since the company will break even when Revenue is equal to Cost, we therefore equate equations (1) and (2) and then solve for x as follows:
10x = 4,700 + 2x
10x - 2x = 4,700
x = 4,700 / 10
x = 470
Therefore, the number of customers that would need to come in the café for the company to break even is 470.

Uno se pierde, el otro se recicla.
Explicación:
El movimiento de nutrientes difiere del flujo de energía en un ecosistema porque los nutrientes se pueden reciclar mientras que, por otro lado, la energía se pierde en el ecosistema. Tanto los nutrientes como la energía fluyen en la misma dirección y toda la energía del ecosistema proviene del sol, que es la principal fuente de energía. Entonces podemos decir que la energía perdida y los nutrientes se reciclan en el ecosistema.

Answer:
18x^2 - 30x
Step-by-step explanation:
Distribution:
You just have to distribute 6x by each term in the parenthesis.
Equation: 6x(3x-5)
(You can also think of it as: 6x * 3x + 6x * -5)
18x^2 - 30x
This is as simplified as can it can be.
(You can’t add terms that have different variables, seeing as the first term has x^2 and the second one only has x).

Brianne's town is building a pool based on a scale drawing that is 20 centimeters by 10 centimeters and uses the scale 1 cm:250 cm. What is the area of the pool in square meters? Enter the area of the pool in the box.
Answer:
[tex]A=1250m^2[/tex]
Step-by-step explanation:
From the question we are told that
Dimension of drawing
20 centimetres by 10 centimetres
Scale of drawing
1 cm:250 cm
Generally the the Main dimension of the pool is mathematically given as
[tex]L=length\ of\ scaled\ pool*250 cm\\B=length\ of\ scaled\ pool*250 cm\\L=20*250=5000 cm=50m\\B=10*250=2500 cm=25m[/tex]
Therefore Area Aof main pool is mathematically given as
[tex]A=50m*25m=1250 m^2[/tex]
[tex]A=1250m^2[/tex]
Question 12 (2 points)
Solve the system of equations using subsititution.
y = 2x - 3
y + 5 = 3x
Answer:
(2,1)
x = 2
y = 1
Explanation:
Check the image
Answer:
(2,1)
Step-by-step explanation:
Since we already have an equation for y, all we need to do is plug that into y in the other equation.
y + 5 = 3x
(2x - 3) + 5 = 3x
2x - 3 + 5 = 3x
2x + 2 = 3x
2 = x
Now that we know y, we just need to plug the value of x into the equation.
y = 2(2) - 3
= 4 - 3
= 1
Consider this equation.

A scientist planted seeds in 4 sections of soil for an experiment. Not all of the
seeds grew into plants. After 20 days, the scientist counted the number of
plants in each of the 4 sections. The results are shown in the table.
• Use the data in the table to determine approximately how many plants
grew per square foot.
• Explain or show how you determined your approximation.
• Let y be the number of plants expected to grow in x square feet. Write an
equation the scientist could use to model the relationship between y and x.
Answer:
I think you would multiply 20 × 4 and the answer would be 80 that the scientist counted the number of plants in each 4 sections after 20 days.
The number of plants per square foot will be; 48.
Given that scientist planted seeds in 4 sections of soil for an experiment. Not all of the seeds grew into plants. After 20 days, the scientist counted the number of plants in each of the 4 sections.
What is addition?The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.
The number of plants per square foot:
= (25 × 13) + (100 × 38) + (125 × 47) + (150 × 62) / (25 + 100 + 125 + 150)
= (325 + 3800 + 5875 + 9300) / 400
= 48.25
Thus, it was illustrated by the number of plants and size of sections.
Thus, the number of plants per square foot will be 48.

7. A triangle has side lengths of 9 and 5. Which of the following cannot be the length of the third side? *
The values less than 4 or greater than 14 cannot be the length of the third side
Which cannot be the length of the third side?From the question, we have the following parameters that can be used in our computation:
Side lengths of 9 and 5.
Represent the third length of the triangle with x
So, we have the following representation (using the triangle inequality theorem)
a + b ≥ c.
Substitute the known values in the above equation, so, we have the following representation
9 + 5 ≥ x
9 + x ≥ 5
5 + x ≥ 9
Evaluate the sum
14 ≥ x
x ≥ -4
x ≥ 4
So, we have
14 ≥ x
x ≥ 4
Combine
4 ≤ x ≤ 14
This means that values less than 4 or greater than 14 cannot be the length of the third side

The measure that cannot be the length of the third side is 14. Option
How to determine the lengthAn important rule to remember about triangles is called the third side rule:
Third side rule of triangles states that;
The length of the third side of a triangle is less than the sum of the lengths of the other two sides and greater than the (positive) difference of the lengths of the other two sides.
For this triangle, the length of the third side must be greater than
9- 5= 4
Also, the length of the third side must be less than
9 + 5 = 14
Hence, all the answers are possible except for answer D, which is equal to 14 but not less than 14.
