maggie has only dimes and quarters in her purse. she has 27 coins with a total value of 4.05. how many dimes does maggie have in her purse
By solving a system of equations, we will see that Maggie has 18 dimes and 9 quarters.
How to write the system of equations?First, we define the variables that we will use:
D = number of dimes.Q = number of quarters.There are a total of 27 coins, so:
Q + D = 27.
The total value is 4.05, so:
Q*0.25 + D*0.10 = 4.05
Then our system of equations:
Q + D = 27
Q*0.25 + D*0.10 = 4.05
To solve this we need to isolate one of the variables in one of the equations, I will isolate Q in the first one.
Q = 27 - D
Now we can replace this on the other equation and solve it for D:
(27 - D)*0.25 + D*0.10 = 4.05
6.75 - D*0.25 + D*0.10 = 4.05
6.75 - D*0.15 = 4.05
6.75 - 4.05 = D*0.15
2.70 = D*0.15
2.70/0.15 = D = 18
So she has 18 dimes, and then the other 9 conis must be quarters.

A grocery store bought milk for $2.20 per half gallon and stored it in two refrigerators. During the night, one refrigerator malfunctioned and ruined 13half gallons. If the remaining milk is sold for $4.04per half gallon, how many half gallons did the store buy if they made a profit of $116.76?
Total of 92 half gallons of milk they bought.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say they bought x half a gallon of milk.
Cost of buying ⇒
x × 2.20 = 2.2x
Since 13 half gallons were destroyed so
Remaining = x - 13
The selling price of remaining milk ⇒
(x - 13) × 4.04
Now,
Profit = selling price - cost of buying.
116.76 = (x - 13) × 4.04 - 2.2x
4.04x - 2.2x - 52.52 = 116.76
1.84 x = 169.28
x = 92
Hence "Total of 92 half gallons of milk they bought".

What are the two numbers less than 20 with the most factors
Final answer:
The two numbers less than 20 with the most factors are 12 and 18, as each of them has six factors.
Explanation:
The question you're asking pertains to identifying the two numbers less than 20 that have the most factors. To find the numbers with the most factors, we list the number of factors for each number less than 20 and determine which have the most. Factors are the numbers you can multiply together to get another number. For example, 2 and 5 are factors of 10 because 2 x 5 = 10.
The number 12 has the factors 1, 2, 3, 4, 6, and 12, totaling 6 factors. On the other hand, the number 18 has the factors 1, 2, 3, 6, 9, and 18, also totaling 6 factors. Hence, the two numbers with the most factors less than 20 are 12 and 18, each with six factors.

Professor Bartlett teaches a class of 12 students. She has a visually challenged student, Louise, who must sit in the front row next to her tutor, who is also a member of the class. Assume that the front row has seven chairs, and the tutor must be seated to the right of Louise. How many different ways can Professor Bartlett assign students to sit in the first row
Final answer:
Professor Bartlett can arrange the students in 1,440 different ways in the first row, considering Louise must sit next to her tutor on the right.
Explanation:
Professor Bartlett teaches a class of 12 students and needs to seat them in the front row which consists of 7 chairs. Specifically, Louise, who is visually challenged, must sit next to her tutor on the right side. To determine the number of different ways the students can be seated in the first row, we first consider the places of Louise and her tutor. Since Louise's tutor must be seated to her right, they can be viewed as a single entity with two internal arrangements: Louise on the left and the tutor on the right. Therefore, there are now effectively 6 entities to arrange (Louise and her tutor considered as one, plus the 5 other students) in 6 chairs in the front row.
The number of ways to arrange 6 entities in 6 spots is calculated by 6 factorial (6!), which equals 720. However, since Louise and her tutor can switch places within their designated spot, we must multiply this number by the 2 internal arrangements possible, resulting in 720 * 2 = 1,440 different seating arrangements for the first row.
