The family likes peaches and other fruits. The local farmer’s market is selling fresh peaches at a discounted price. If the farmer’s market sold 35% of its produce and has 260 peaches remaining, how many peaches did it originally have on hand? Show all your work and explain how you used equivalent ratios to solve the problem.
The farmer's market originally had 400 peaches on hand.
What is an equation?
An equation is a mathematical statement that shows that two expressions are equal. It typically consists of variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and radicals.
Let's use x to represent the original number of peaches the farmer's market had on hand.
We know that the farmer's market sold 35% of its produce, which means it sold 0.35x peaches. The remaining number of peaches can be calculated by subtracting the number of peaches sold from the original number of peaches:
remaining peaches = x - 0.35x
We also know that there are 260 peaches remaining, so we can set up an equation:
260 = x - 0.35x
Simplifying this equation, we can combine like terms:
260 = 0.65x
To solve for x, we need to isolate the variable by dividing both sides by 0.65:
x = 260 / 0.65
x = 400
Therefore, the farmer's market originally had 400 peaches on hand.
To explain how we used equivalent ratios, we used the fact that the farmer's market sold 35% of its produce. This can be represented as a ratio of 35/100 or 0.35. We then used this ratio to find the number of peaches sold, which is 0.35x. We also used the fact that the remaining peaches are the original peaches minus the peaches sold, or x - 0.35x. Finally, we set up an equation using the remaining peaches and solved for x to find the original number of peaches.
Hence, the farmer's market originally had 400 peaches on hand.

solve for x. 4(x+56.5)=30x-112
Answer:
x = 13
Step-by-step explanation:
Let's simplify and solve for x:
4(x+56.5) = 30x - 112
First, we distribute the 4:
4x + 4(56.5) = 30x - 112
Simplifying the expression:
4x + 226 = 30x - 112
Now we move all the x terms to one side and all the constants to the other:
226 + 112 = 30x - 4x
338 = 26x
Finally, we solve for x by dividing both sides by 26:
x = 13
Therefore, the solution to the equation 4(x+56.5)=30x-112 is x = 13.
Answer:
x=9.94
Step-by-step explanation:
4x + 226 = 30x - 112
226+112 = 34x
338 = 34x
338/34=x

A herd of elk is released onto state game lands. The expected population P of the herd can be modeled by the equation below where t is the time in years since the initial number of elk were released. P = (10 + 3.3t)/(1 + 0.1t)
(a) State the domain of the model.
t ≥ 0
t ≠ 10
t < 0
t > 0
t ≤ 0

t ≠ -10
(b) Find the initial number of elk in the herd. ________
(c) Find the populations of elk after 25, 59, and 113 years. (Round your answers to the nearest integer.) _____________
(d) Is there a limit to the size of the herd? If so, what is the expected population? (Round your answer to the nearest integer. If there is no limit, enter NONE.) ____________
Since the denominator of the expression (1 + 0.1t) cannot be zero, the domain of the model is between t = 0 and t = -10.
How Can I Determine an Equation's Domain and Range?In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x). Simply put, x=g(y) will calculate the function's range after we identify g's domain (y).
(b) We must assess the model at t = 0 in order to determine the starting number of elk in the herd:
P = (10 + 3.3t)/(1 + 0.1t)
P = (10 + 3.3(0))/(1 + 0.1(0))
P = 10/1
P = 10
(c) We can easily enter the relevant values of t into the model to determine the populations of elk after 25, 59, and 113 years, then round the results to the nearest integer.
When t = 25:
P = (10 + 3.3t)/(1 + 0.1t)
P = (10 + 3.3(25))/(1 + 0.1(25))
P ≈ 47
When t = 59:
P = (10 + 3.3t)/(1 + 0.1t)
P = (10 + 3.3(59))/(1 + 0.1(59))
P ≈ 189
When t = 113:
P = (10 + 3.3t)/(1 + 0.1t)
P = (10 + 3.3(113))/(1 + 0.1(113))
P ≈ 458
(d) We can use the expression's limit as t approaches infinity to determine the expected population limit:
lim P as t → ∞ = lim (10 + 3.3t)/(1 + 0.1t) as t → ∞
Using L'Hopital's rule, we can find that the limit is equal to:
lim P as t → ∞ = lim 3.3/0.1 as t → ∞
lim P as t → ∞ = 33

Hence, a 93% confidence range for the actual proportional difference between the two populations equation (represented by the two samples) is between -0.086 and 0.142.
What is the equation?A mathematical equation connects two statements with the equals sign (=), which stands for equivalence. The equivalence of two mathematical propositions is established by a mathematical assertion that is utilized in algebraic equations. For instance, the equal sign separates the numbers 3x + 5 and 14 in equation 3x + 5 = 14. Use a mathematical formula to understand the relationship between the two sentences written on opposite sides of a letter. Usually, the program's particular logo matches it. A good example is 2x - 4 = 2.
For the initial example:
Sample proportion: 0.649 (p1 = 24/37)
Standard deviation SE1 is equal to
[tex]\sqrt{(p^1*(1-p^1))} /n1=\sqrt{(0.649*(1-0.649))/37)0.087}[/tex]
Regarding the second example:
P2 = 54/87 0.621 is the sample proportion.
The standard deviation SE2 is equal to
[tex]\sqrt{(p^2*(1-p^2))} /n2=\sqrt{(0.621*(1-0.621))/87)0.72}[/tex]
The crucial value for a 93% confidence interval has to be calculated next. We may use the conventional normal distribution and large sample size to obtain the z-value that represents the center 93% of the distribution:
[tex]1.812z=invNorm(\frac{1+0.93}{2} )[/tex]
We can finally determine the confidence interval:
CI is equal to (p1-p2) z*sqrt(SE12 + SE22)
CI is calculated as (0.649 - 0.621) 1.812*sqrt(0.0872 + 0.0722)
CI = 0.028 ± 0.114
CI = (−0.086, 0.142)
The real proportional difference between the two populations (represented by the two samples) thus lies between -0.086 and 0.142, with a 93% confidence interval.

Maria and Connor are doing yard work for a neighbor. They make a total of $595.54. Since Connor works more hours than Maria, Connor gets 69% of the money. About how much (in whole
dollars) does Connor make?
Connor makes about
Answer: Since Connor gets 69% of the money, Maria gets the remaining 31%:
100% - 69% = 31%
Let's first find out how much money Maria makes:
Maria's share = 31% of $595.54
Maria's share = 0.31 x $595.54
Maria's share = $184.61
Now, to find out how much Connor makes, we can subtract Maria's share from the total:
Connor's share = Total - Maria's share
Connor's share = $595.54 - $184.61
Connor's share = $410.93
Therefore, Connor makes about $410.93 (rounded to the nearest dollar).

Which first step could you take to solve this system using elimination?
Equation #1: 2x + 18y = -9
Equation #2: 4x + 18y = -27
(Choose all correct answers)
Multiply equation #1 by 2
Multiply either equation by -1
Multiply equation #1 by -2
Multiply equation #1 by -3
Answer:
Step-by-step explanation:
To use elimination method, we need to eliminate one of the variables (x or y) by adding or subtracting the two equations. To do this, the coefficients of one of the variables in the two equations should be the same or opposite.
Looking at the two equations:
Equation #1: 2x + 18y = -9
Equation #2: 4x + 18y = -27
We can see that the coefficients of y are already the same in both equations. So, we can eliminate y by subtracting Equation #1 from Equation #2.
However, to do this we need to make sure that the coefficients of x in the two equations are opposites, i.e., one is positive and one is negative.
Therefore, the first step we could take to solve this system using elimination is to multiply Equation #1 by -2 to get:
-4x - 36y = 18
Now the coefficients of x in the two equations are opposites, so we can subtract Equation #1 from Equation #2 to eliminate y and solve for x.
So, the correct answer is:
Multiply equation #1 by -2.

Find the missing angle
Answer:
55
Step-by-step explanation:
The ? angle is 55 degrees since every triangle's angles add up to 180 degrees. We have 2 angles, one with 70 and another with 55, so we add them to get 125. Then we subtract 125 from the total angle of a triangle, 180-125, to get 55.
the answer is 55
they have the same degrees hope this helps
1) Write an algebraic expression, The quotient of g and 4 added to 15
2) Write an algebraic expression, 6 minus the difference of y and 3
3) Write an algebraic expression, the product of a number d and 8
The algebraic expressions for the given questions are found as:
1) g/4 + 15.
2) 6 - y + 3
3) d * 8
What are algebraic expressions?
A mathematical expression made up of variables, constant algebraic numbers, and algebraic operations are known as an algebraic expression. Everything with a variable value is anything whose value changes over time. Variables in expressions are often represented by letters of the alphabet. Finding the simplified term of the given expression is the goal of simplifying the algebraic expression. We must first understand how to join like terms, factor a number, and the order of operations before we can factorise or simplify the expression. When like terms are combined, the constant terms are divided for the purpose of simplicity and the variables with the same degree are grouped together.
1) The quotient of g and 4 is given by g/4.
Now, this is added to 15.
So the algebraic expression is g/4 + 15.
2) The difference between y and 3 is y - 3.
Now from 6, this difference is subtracted.
So the expression becomes,
6 - (y-3) = 6 - y + 3
3) The product of two numbers is found by multiplying the numbers.
So the expression is :
d * 8
Therefore the algebraic expressions for the given questions are found according to the given statements.

The table that shows a proportional relationship is Table A.
What is a proportional relationship ?A proportional relationship is a type of relationship between two variables in which the ratio of their values remains constant. In other words, as one variable increases or decreases, the other variable also increases or decreases in proportion to it.
In table A, we see that :
= 150 / 3
= 50
= 200 / 4
= 50
= 250 / 5
= 50
Every single value of y, gives the same value of x so this means that the table shows a proportional relationship.

The equation of the line crossing (3, 1 / 2)(5, 5) is y = 9 / 4 x - 25 / 4.
How to find equation of a line?The equation of a line can be represented in slope intercept form as follows:
y = mx + b
where
m = slope of the lineb = y-interceptHence, let's find the equation of the line crossing (3, 1 / 2)(5, 5).
m = 5 - 1 / 2 / 5 - 3
m = 9 / 2 × 1 / 2
m = 9 / 4
Hence, let's find the y-intercept using (5, 5)
y = 9 / 4 x + b
5 = 9 / 4(5) + b
5 - 45 / 4 = b
b = 20 - 45/ 4
b = - 25 / 4
Therefore, the equation of the line is y = 9 / 4 x - 25 / 4.

Which of the lines or segments below is secant to circle
The lines or segments which are secant to a circle are:
AK, TW, RN & UN
What is secant of the circle?A line that crosses a circle at two different locations is referred to as a "secant of a circle" in geometry. The Latin verb "secare," which meaning "to cut," is where the English term "secant" originates.
More technically, a secant of a circle is a line that crosses it twice, whereas a tangent of a circle is a line that crosses it only once. A circle's diameter is a chord that runs through its center, whereas a chord of a circle is a line segment connecting two locations on the circle.
Given that,
Two circle which contains various tangents, normal & secants
As we know from the definition of secant it intersect the circle at two points,
Line segments AK, TW, RN & UN are intersecting the circle at two points,
so all this segments are secant of the circle.

A retailer buys merchandise from a supplier with an invoice amount of $12,400. The terms of the sale are 6/20, n/30. What is the net amount due (in $) on the order if the bill is paid by the 20th day?
If the retailer pays the invoice within 20 days and takes the discount, the net amount due is $11,656.
The sale's "6/20, n/30" clause allows the retailer to choose between paying the invoice in full within 30 days or taking advantage of a 6% discount if they do it within 20 days. If the bill is paid by the 20th day, we can determine the net amount owed as follows:
Then, we multiply the invoice amount by the discount rate to determine the amount of the discount:
Discount: $744 ($12.400 x 0.06)
The amount owed if the discount is taken is then determined by deducting the discount from the invoice amount:
Discounted amount due: $12,400 - $744 = $11,656
The net amount owed is therefore $11,656 assuming the store pays the invoice within 20 days and applies the reduction.

Each statement describes a transformation of the graph of f(x) = x. Which statement correctly describes the graph of function g if g(x) = f(x) − 11? A. It is the graph of f(x) where the slope is decreased by 11. B. It is the graph of f(x) translated 11 units down. C. It is the graph of f(x) translated 11 units up. D. It is the graph of f(x) where the slope is increased by 11.
The right response is B. It is the graph of f(x) scaled down by 11 units.
For any given value of x, the output of f(x) is subtracted by 11 to get the function g(x) = f(x) - 11.
The result is the same as the input for the function f(x) = x. Thus, if we take 11 out of the result, we get:
g(x) = f(x) - 11 = x - 11
In other words, the graph of g(x) is the graph of f(x), 11 units lower.
Thus, assertion B is the correct one. It is the graph of f(x) scaled down by 11 units.
