what was john's age 4 years ago if he will be y years old in 5 years
Answer: y - 9
Step-by-step explanation:
Because "y" will be John's age in 5 years, we subtract 5 to get to his age now.
y-5
Four years ago will be just subtracting 4.
y-9
4 years ago John age as per the given condition is (y - 9) years old .
Let's assume John's current age is J years.
According to the information ,
In 5 years, John's age will be y years.
So, in 5 years, John's age will be J + 5 = y.
Now, find John's age 4 years ago. This means we need to subtract 4 years from John's current age.
John's age 4 years ago = J - 4.
Since John's age in 5 years will be y, we can rewrite the first equation as:
J + 5 = y
Now, use this information to find John's age 4 years ago:
John's age 4 years ago
= J - 4
= (y - 5) - 4
= y - 9.
Therefore, John's age 4 years ago was (y - 9) years old.

Answer: Hi! Read the explanation below:
Brainliest?
Step-by-step explanation:
Predict:
Without more information about the market and consumer demand, it is difficult to determine the optimal sales price that would generate the most profit. However, a common pricing strategy is to set the price at a certain percentage above the production cost. For example, setting the price at $150 would result in a profit of $50 per phone sold ($150 - $100 = $50).
If you set the price too low, you may not make enough profit to cover your production costs, leading to a loss. Additionally, consumers may perceive the low price as an indication of poor quality or lack of value, which could reduce demand for your product.
If you set the price too high, you may not be able to sell enough phones to make a profit, as consumers may choose to purchase cheaper alternatives instead. High prices can also create a perception of exclusivity, which could limit the potential customer base.
Calculate:
See the table below.
Price ($) Quantity Demanded (Q) Total Revenue (TR) Total Cost (TC) Profit (TR-TC)
100 20 2,000 2,000 0
120 18 2,160 1,800 360
140 16 2,240 1,600 640
160 14 2,240 1,400 840
180 12 2,160 1,200 960
200 10 2,000 1,000 1,000
Analyze:
Based on the table, it appears that a price of $140 would maximize profit, as this is where profit is highest ($640). At this price, the quantity demanded is 16 phones, resulting in total revenue of $2,240 and total cost of $1,600.
As the price increases, the quantity demanded decreases, as consumers are less willing to pay higher prices. This leads to lower total revenue and profit.
The x-intercept is when profit is equal to zero, or where TR = TC. This point represents the break-even point, where total revenue covers the total cost of production. In this case, the x-intercept is at a price of $150.
Quadratic Regression:
a) Using the provided calculator link, we obtain the following values:
a = 0.05
b = -10
c = 500
r2 = 0.9
b) The standard form of the equation that represents the data is:
f(x) = 0.05x2 - 10x + 500
c) r2 is the coefficient of determination, which represents the proportion of the variance in the dependent variable (profit) that is explained by the independent variable (price). An r2 value of 0.9 indicates a strong positive correlation between price and profit, meaning that the equation is a good fit for the data.
d) See graph below.
Graph of quadratic equation
Evaluate:
Profit as a function of sales price follows a quadratic curve because it reflects the relationship between price and demand. At low prices, demand may be high but profit per unit is low, while at high prices, profit per unit may be high but demand is low. The optimal price is the one that balances these

A worm wriggled forward 4/5 of an inch in 3 minutes. At that rate, how far would the worm go in 1 minute?
Answer:
4/15 of an inch
Step-by-step explanation:
A worm wriggled forward 4/5 of an inch in 3 minutes.
=> At that rate, the distance the worm would go in 1 minute is:
D = (4/5)/3 = 4/(5x3) = 4/15 of an inch
Hope this helps!
The worm would go 0.267 inches in 1 minute.
How far would the worm go in 1 minute?
By Unitary method,we can solve this problem.
But now question is what is the use of Unitary method ?
By some examples we can understand this concept.
Let cost of 5 book is 500 rupees.
By Unitary method, cost of 1 book is
\(\frac{500}{5} \\ = 100 \: rupees\)
Cost of 100 books is \((100 \times 100) = 10000 \: rupees\)
Again for another example let length of 1 rope is 5 m
Then by Unitary method length of 5 rope is \((5 \times 5) = 25 \: m\)
Given,a worm wriggled forward 4/5 of an inch in 3 minutes.
So,in 3 minutes the worm can cover 4/5 of an inch
\( = \frac{4}{5} \times 1 \: inch \\ = \frac{4}{5} \: inch\)
Now we want to find how far would the worm go in 1 minute ?
In 3 minutes the worm covers 4/5 inche
By Unitary method, in 1 minute the worm covers
\( \frac{4}{5} ÷ 3 = \frac{4}{15} = 0.267 \: inches\)
Therefore,the worm would go 2.4 inches in 1 minute

58 children go into the hall for a concert. There are six seats in a row. How many rows are needed to seat everyone?
To seat all 58 children in the hall for the concert, 10 rows are needed.
1. Determine the number of children per row: Since there are 6 seats in a row, each row can accommodate 6 children.
2. Divide the total number of children by the number of children per row: Divide 58 (the total number of children) by 6 (the number of children per row).
58 ÷ 6 = 9 with a remainder of 4
This means that 9 full rows can be formed, and there will be 4 children left after the last full row.
3. Check if there are any remaining children: Since there are 4 children remaining, they cannot form a complete row by themselves.
4. Calculate the number of rows needed: Add 1 to the number of full rows to account for the remaining children.
9 full rows + 1 row for the remaining children = 10 rows in total.
Therefore, to seat all 58 children in the hall for the concert, 10 rows are needed.

A contractor better job at $750 for materials plus $43 per hour for labor. The total cost for the job can be modeled by C= 43H+ 750$.
Find the number of hours that he has for the job if the owner would like the total cost to be under $2000, rounded to the nearest hour.
The contractor has a maximum of 29 hours (rounded down) to complete the job while keeping the total cost under $2000.
To find the number of hours the contractor has for the job while keeping the total cost under $2000, we can use the given cost model equation: C = 43H + 750.
Since the owner wants the total cost to be under $2000, we can set up the inequality:
43H + 750 < 2000
Now, let's solve this inequality for H, the number of hours:
43H < 2000 - 750
43H < 1250
Dividing both sides of the inequality by 43:
H < 1250/43
To determine the maximum number of hours the contractor has for the job, we need to round down the result to the nearest whole number since the contractor cannot work a fraction of an hour.
Using a calculator, we find that 1250 divided by 43 is approximately 29.07. Rounding down to the nearest whole number, we get:
H < 29
Using the cost model equation C = 43H + 750, where C represents the total cost and H represents the number of hours, we set up the inequality 43H + 750 < 2000 to satisfy the owner's requirement of a total cost under $2000.
By solving the inequality and rounding down to the nearest whole number, we find that the contractor has a maximum of 29 hours to complete the job within the specified cost limit.

What is the meaning of "A group G whose order is a prime number has only two subgroups, G itself and 1 = {1}"?
If G is not a cyclic group, then it does not have a subgroup of order p. Conversely, if G is cyclic, then it has a unique subgroup of order p.
The statement "A group G whose order is a prime number has only two subgroups, G itself and 1 = {1}" means that if G is a group with a prime number of elements, then the only subgroups of G are the trivial subgroup {1} and the group G itself.
In other words, there are no other proper subgroups of G besides these two.
The statement "A group G whose order is (p-1) where p is a prime number has a subgroup of order p if and only if G is cyclic" means that if G is a group with (p-1) elements, where p is a prime number, then G has a subgroup of order p if and only if G is a cyclic group.
