A Potential Answer:
One thing that has kept me from saving in the past is my confusion of my "wants" and "needs". An outcome of this is me constantly spending money on things that aren't necessary instead of buying things that are useful. An example of this is when I went to the store and decided to buy expensive band merchandise, as well as my groceries. If I hadn't bought the band merchandise, I could have saved $30. To fix this, I started to work on my self-control and budget management.
I hope this helped!

What is the reciprocal of
2/7?
Answer:
7/2
Step-by-step explanation:
To find the reciprocal of a fraction we just flip it
2/7 =7/2
The reciprocal of 2/7 is 7/2, and it plays a significant role in various mathematical operations involving fractions.
The reciprocal of a fraction is obtained by interchanging the numerator and denominator. For the fraction 2/7, its reciprocal is 7/2. To understand why this is the case, let's break it down.
When we take the reciprocal of a fraction, we essentially flip it upside down. In the case of 2/7, we switch the positions of 2 (numerator) and 7 (denominator) to get 7/2. This reciprocal property holds true for any fraction.
The reciprocal of 2/7 is an essential concept in mathematics, especially when dealing with division of fractions. When you divide a fraction by another fraction, it is equivalent to multiplying the first fraction by the reciprocal of the second fraction. So, dividing by 2/7 is the same as multiplying by 7/2.
In conclusion, the reciprocal of 2/7 is 7/2, and it plays a significant role in various mathematical operations involving fractions.

Answer:
100 and 25 are the perfect squares
Our answers are 100 and 25.
Some insight:
6 = [tex]\sqrt{6}*\sqrt{6}[/tex] -- We cannot simplify the square root of 6 to integers, so no.
100 = [tex]\sqrt{100}* \sqrt{100}[/tex] = 10*10 -- This is a perfect square
25 = [tex]\sqrt{25}* \sqrt{25}[/tex] = 5*5 -- This is a perfect square
5 = [tex]\sqrt{5}* \sqrt{5}[/tex] -- No.
Prove that
(a) there exist integers m and n such that 2m + 7n = 1.
(b) there exist integers m and n such that 15m + 12n = 3.
(c) there do not exist integers m and n such that 2m + 4n = 7.
(d) there do not exist integers m and n such that 12m + 15n = 1.
(e) for every integer t, if there exist integers m and n such that 15m + 16n = t, then there exist integers rand s such that 3r + 8s = t.
(f) if there exist integers m and n such that 12m + 15n = 1, then m and n are both positive.
(g) for every odd integer m, if m has the form 4k + 1 for some integer k, then m + 2 has the form 4j - 1 for some integer j. (h) for every integer m, if m is odd, then m2 = 8k + 1 for some integer k.
(i) for all odd integers m and n, if mn = 4k - 1 for some integer k, then m or n is of the form 4} - 1 for some integer j.
LStep-by-step explanation:
(a) To proof this statement choose m = 4 and n = -1, from here we have 2(4) + 7(-1) = 1 as required. Hence th statement is true.
(b) To proof this statement choose m = 1 and n = -1, from here we have 15(1) + 12(-1) = 3 as required. Hence the statement is true.
(c) To proof this statement, suppose m and n are integers, since integers are closed under addition and multiplication then 2m, 4n and 2m + 4n are all integers. Obviously 2m and 4n are even integers, therefore their sum is also an even integer. This contradicts the equation 2m + 4m = 7, hence there do not exist integers m and n that satisfy the statement.
(d) To proof this statement, suppose m and n are integers, then 12m, 15n and 12m + 15n are all integers, since integers are closed under addition and multiplication. Factoring out 3 from the sum, we have: 3(4m + 5n). Therefore 3(4m + 5n) = 1 is a contradiction, because it will give 4m + 5n = 1/3 and addition of two integers can never give a fraction.
(e) To proof this statement, suppose m and n are integers, then 15m + 16n = t can be rewritten as 3(5m) + 8(2n) = t. Since integers are closed under multiplication, then 5m and 2n are integers. Let 5m = r and 2n = s, then we have: 3r + 8s = t as required.
(f) To proof this statement, suppose that m and n are both negative integers, we see that 12m + 15n = 1 is clearly impossible because the sum would be less than 0. Therefore, if there exist integers m and n such that 12m + 15n = 1, then they must be positive.
(g) To proof this statement, suppose m is an integer and has the form 4k + 1 for some integer k, then m + 2 = 4k + 1 + 2 = 4k + 3 = 4k + 4 - 1 = 4(k + 1) - 1. Since k is an integer then k + 1 is an integer because integers are closed under addition. Therefore, put j = k + 1. Hence we have 4j - 1.
(h) suppose that m is odd, then there is an n such that m = 2n + 1, therefore m² = (2n + 1)² = 4n² + 4n + 1 = 4(n² + n) + 1. Here, we need a lemma that says: suppose k is an integer, k(k + 1) is an even integer. This can be proven intuitively, when k is odd, the term in the bracket becomes even, and the whole expression is even. If k is even, then automatically the whole expression becomes even. Hence, our lemma is proven intuitively. This implies that n² + n is an even integer and can be replaced by 2k for some k that is an integer. Therefore, we have 4(2k) + 1 = 8k + 1 as required.
(i) suppose that m and n are odd integers such that mn = 4k - 1 for some k that is an integer. If we assume that neither m nor is in the for 4j - 1, then:
mn = (4a + 1)(4b + 1) for some a and b that are integers. Expanding that we have mn = 4(4ab + a + b) + 1 which is not in the form 4k - 1 for some k that is an integer as assumed. Therefore, if m and n are odd integers such that mn is in the form 4k - 1 for some k that is an integer, then m and n are in the form 4j - 1 for some j that is an integer.

The auxiliary bookstore in the student center has one checkout counter where one employee operates the cash register. Customers arrive at a rate of 24 per hour following a Poisson distribution and service times are exponentially distributed, with a mean rate of 30 customers per hour. The average purchase per customer is $48. The bookstore considers adding another employee to assist the present operator. There are several options to utilize this additional staff. One is to enable more customers to be served in less time, thus increasing the service rate from 30 customers per hour to 40 customers per hour. Alternatively, the bookstore could redesign to add a second cash register, one has its own line. Assume existing customers split evenly between the two cash registers and each has her/his own line, just like most grocery stores. Finally, the bookstore can use this additional staff as a second register but unlike option 2, there is only one combined line shared by these two registers (like most of the bank tellers). Assume the hourly rate for each employee is $20, regardless what job do they perform. Assume that each customer is only waiting for up to 1 minute to be served, or would renege (i.e., leave the store unpurchased). Which option should the bookstore adopt to minimize the total cost?
