To number the apartments in a building, metal plates with digits were used: one digit on each plate. How many plates were used to number 136 apartments in the building?
Answers
Answer:
301 plates
Step-by-step explanation:
For numbers between 0 and 9, 1 plate was used each.
This means that 10 plates were used.
For numbers between 10 and 99, 2 plates were used for each.
This means that the number of plates used will be:
2 * 90 = 180 plates
For numbers between 100 and 136, 3 plates were used for each.
This means that the number of plates used is:
3 * 37 = 111 plates
The total number of plates used is therefore:
10 + 180 + 111 = 301 plates
301 plates were used in total.

Choice AThe class needs to sell \(3\) cookies to earn 39 cents.Step-by-step explanation:
Please refer to my answer from this question to know more about writing a scenario from a given scenario: brainly.com/question/24599307
Scenario: A class is having a bake sale. The class earns 13 cents for each cookie sold.
We let the number of cookies sold as \(x\) and we let the number of earned cents as \(y\).
If the class sold \(x\) cookies then they will earn \(13x\) cents. We, therefore, have the equation that describes the relationship between the number of cookies sold, \(x\), and the number of cents earned, \(y\), as \(y = 13x\).
Note: Since the class can't sell half a cookie or \(0.8239\) cookies then, in our graph, \(x\) must account for all natural numbers only.
Graphs A and D graphs \(y = 13x\) but \(x\) on graph D accounts for all nonnegative real numbers.
So the correct graph must be Graph A as its \(x\) accounts for all natural numbers only.
\(\rule{6cm}{0.4pt}\)
We are also asked to calculate the number of cookies sold to earn \(39\) cents. This is essentially solving for \(x\) from the equation, \(y = 13x \text { when } y = 39\).
\(39 = 13x \\ 13x = 39 \\ x = \frac{39}{13} \\ x = 3\)
Allison has a loyalty card good for a discount at her local hardware store. The item she wants to buy is priced at $36, before discount and tax. After the discount, and before tax, the price is $30. 96. Find the percent discount
Answers
the percent discount is 14% when the original price and new price are given $36 and $30.96.
Given that,
Original price of item = $36 (that is before discount and the tax)
Price after discount = $30.96
Let the percentage discount be = x
A discount is the reduction of either the monetary amount or a percentage of the normal selling price of a product or service.
To get the percent discount :
x = (original cost - new price)/original price
x = (36 - 30.96)/36
x = 5.06/36
x = 0.14
Percentage discount x , in percentage = 0.14 x 100
Percentage discount = 14%
therefore, the percent discount is 14%

Mufasa, Heloise, Angie, I have written more than a combined total of 22 articles for the school newspaper.Heloise has written 1/4 as many articles does Mufasa has. Gia has written 3/2 as many articles as Mufasa has.
Answers
If we are aware that Mustafa, Heloise, or Gia have penned more than \(22\)pieces altogether. \(M > 8\) This is the number of articles Mustafa might have written.
How to explain number?A numeric is a mathematical number which can be utilized to compute and describe a quantity. Numerical symbols, such as "3," are written to represent numbers. A counting system is a logical way of expressing numbers that uses digits or symbols to represent them.
How come 100 is a number?The fact that we use a decimal (base 10) mathematical notation system for numbers gives the number 100 importance that it probably wouldn't otherwise have. It is a circular numeral with undertones of excellence.
\(M + H + A > 22\)
We also know that:
\(H = 1/4M\)
\(A = 3/2M\)
We can substitute these expressions into the first equation:
\(M + 1/4M + 3/2M > 22\)
Multiplying everything by the common denominator of 4:
\(4M + M + 6M > 88\)
\(11M > 88\)
\(M > 8\)
So, Mufasa has written more than \(8\) articles.
Using the equation \(H = 1/4M\), we can find that Heloise has written:
\(H = 1/4(8) = 2\)
Using the equation \(A = 3/2M\), we can find that Angie has written:
\(A = 3/2(8) = 12\)
Therefore, Mufasa has written more than \(8\) articles, Heloise has written \(2\)articles, and Angie has written \(12\) articles.
To check if their combined total is more than \(22\):
\(M + H + A = 8 + 2 + 12 = 22\)
So, their combined total is exactly \(22\), which means that they have not written more than \(22\) articles for the school newspaper.

julie is a 14 year old student at odyssey charter high school. she is getting ready for beach season and wants to lose 3 pounds in four weeks. on average how many extra calories does julie need to burn each week to meet her goal?
Answers
To achieve her goal, Julie needs to burn an extra 2,625 / 7 = 375 calories every day.
Find how many extra calories neededTo calculate how many extra calories Julie needs to burn each week to lose 3 pounds in four weeks, we need to use the following formula:
1 pound of body weight = 3,500 calories
3 pounds of body weight = 3 x 3,500 = 10,500 calories
Julie wants to lose 3 pounds in 4 weeks.
Therefore, her weekly goal would be to lose 10,500 / 4 = 2,625 calories.
To burn 2,625 extra calories in a week, Julie needs to burn 375 calories extra each day.
Therefore, she needs to burn an extra 2,625 / 7 = 375 calories every day to achieve her goal.

Answers
The function f can be implemented using a single 4-to-1 multiplexer and two inverters.
A 4-to-1 multiplexer is a digital logic component that selects one of four input signals based on the select lines. It has four data inputs (D0, D1, D2, D3), two select lines (S0, S1), and one output (Y). By properly connecting the inputs and select lines, we can realize the desired function f.
To implement the function f using a single 4-to-1 multiplexer and two inverters, we need to carefully assign the input signals and select lines to achieve the desired behavior. The truth table of the function f will guide us in determining the appropriate connections.
First, we can use the inverters to complement the required inputs if needed. Then, we can connect the complemented and uncomplemented inputs to the select lines of the multiplexer. The output of the multiplexer will be the result of the function f.
By carefully selecting the input assignments and connections, we can effectively implement the function f using a single 4-to-1 multiplexer and two inverters. This approach offers a compact and efficient solution for realizing the desired logic function.

A. How large a monthly payment must Holly Krech make if she saves for her payout annuity with an ordinary annuity, which she sets up thirty years before her retirement?
B. how large a monthly payment must she make if she sets the ordinary annuity up twenty years before her retirement?
Answers
A. To save for her payout annuity with an ordinary annuity set up thirty years before her retirement, Holly Krech must make a monthly payment of $175.97.
B. If she sets up the ordinary annuity twenty years before her retirement, Holly Krech must make a monthly payment of $432.00.
What is the monthly payment required for an ordinary annuity set up 30 years before retirement?To calculate the monthly payment for an ordinary annuity set up thirty years before retirement, we can use the formula for the present value of an ordinary annuity. Given the deposit amount of $218,437.048 and the total amount received from the annuity of $432,000, and solving for the monthly payment, we find that Holly must make a monthly payment of $175.97.
How much must be paid monthly for an ordinary annuity set up 20 years before retirement?For an ordinary annuity set up twenty years before retirement, we use the same formula for present value. With the deposit amount and total amount received unchanged, we solve for the monthly payment, which comes out to be $432.00.
It's important to note that the monthly payment increases when the annuity is set up closer to the retirement date. This is due to the shorter time period available for saving, resulting in a higher required contribution to reach the desired payout amount.

The measures of two supplementary angles are
(x + 1) and ( 2x +1).
Write an equation that shows the relationship between the two angle measures and determine the value of x.
Answers
An equation that shows the relationship between the two angle measure is 3x + 2 = 180 and the value of x is 59.
Let us consider the two supplementary angles with measures (x + 1) and (2x + 1). Since they are supplementary angles, we know that their sum is equal to 180 degrees. We can write this relationship between the two angle measures as an equation:
(x + 1) + (2x + 1) = 180
Simplifying this equation, we get:
3x + 2 = 180
Now, we can solve for x by isolating it on one side of the equation. To do this, we can subtract 2 from both sides of the equation:
3x = 178
Finally, we can solve for x by dividing both sides of the equation by 3:
x = 59.33
Therefore, we should round the value of x to the nearest whole number, which is 59.

Consider a LOS transmitting antenna with a height of 75 m.
a. Calculate the maximum distance between the transmitting
antenna and the receiving antenna if the receiving antenna is at
ground level.
b.
Answers
a. The maximum distance between the transmitting antenna and the receiving antenna, when the receiving antenna is at ground level, is approximately 30,955 meters.
b. The maximum distance between the transmitting antenna and the receiving antenna, when the receiving antenna height is increased to 50 m, is still approximately 30,955 meters.
a. To calculate the maximum distance between the transmitting antenna and the receiving antenna when the receiving antenna is at ground level (height = 0), we can use the formula for the horizon distance:
d = √((2 * h * R) + h^2)
where:
d is the maximum distance between the antennas,
h is the height of the transmitting antenna, and
R is the radius of the Earth.
Height of the transmitting antenna, h = 75 m
Height of the receiving antenna, h = 0 m
Radius of the Earth, R ≈ 6,371,000 meters
Substituting the values into the formula:
d = √((2 * 75 * 6,371,000) + 75^2)
d ≈ √((957,150,000) + 5,625)
d ≈ √(957,155,625)
d ≈ 30,955 meters (approximately)
Therefore, the maximum distance between the transmitting antenna and the receiving antenna, when the receiving antenna is at ground level, is approximately 30,955 meters.
b. Now, if the height of the receiving antenna is increased to 50 m, we can calculate the new maximum distance using the same formula.
Height of the transmitting antenna, h = 75 m
Height of the receiving antenna, h = 50 m
Radius of the Earth, R ≈ 6,371,000 meters
Substituting the values into the formula:
d = √((2 * 75 * 6,371,000) + 75^2)
d ≈ √((957,150,000) + 5,625)
d ≈ √(957,155,625)
d ≈ 30,955 meters (approximately)
Therefore, the maximum distance between the transmitting antenna and the receiving antenna, when the receiving antenna height is increased to 50 m, is still approximately 30,955 meters. The height of the receiving antenna does not affect the maximum distance in a LOS scenario.
Your question is incomplete but most probably your full question was

What is an arithmetic sequence in math?
Arithmetic sequences are those in which each term is increased by the addition or subtraction of a constant k. In contrast to a geometric sequence, where each term rises by being multiplied by or divided by a constant k,A series of numbers is considered to be an arithmetic progression or sequence if there is a constant difference between the terms. Consider the mathematical progression with a common difference of 2 in the numbers 5, 7, 9, 11, 13, and so on.An is equal to a1 + d(n - 1), where d is the common difference across terms in the series, and a1 is the first term in the sequence.This is an arithmetic sequence since there is a common difference between each term. In this case, adding 9 to the previous term in the sequence gives the next term. In other words, \(a_{n}\)= \(a_{1}\)+ d ( n - 1 )
Arithmetic Sequence: d = 9
This is the formula of an arithmetic sequence.
\(a_{n}\) = \(a_{1}\) + d ( n - 1 )
Substitute in the values of \(a_{1}\) = 4 and d = 9
\(a_{n}\)= 4 + 9 ( n - 1 )
\(a_{n}\)= 4 + 9n - 9
\(a_{n}\) = 9n - 5
.30th term = \(a_{n}\) = \(a_{1}\)+ d ( n - 1 )
= \(a_{30}\)= 4 + 9 ( 30 -1 )
