In what quadrant on the coordinate plane is the point (5,-2) located?
Answers
Cause Quadrant 4 Is a mixture of negative and positive numbers and since x = 5 is positive you would look for the 5 and go down -2 which would be in quadrant 4.

m stands for the number of months
⇒ Company A has a $20 signing fee and charges $40 monthly. Signing fee will be the constant, because it's not influenced by the number of months. 40 will be the coefficient of m. The expression will be 20 + 40m
⇒ Company B has no signing fee and charges $45 monthly. 45 will be the coefficient of m, because the total charge is influenced by the number of months. The expression will be 45m
Determine the number of months
For both costs being equal, write an equation that equalizes both expression
45m = 20 + 40m
solve for m
45m - 40m = 20
5m = 20
m = 20/5
m = 4
For both costs being equal, it needs 4 months

Dakota’s dance troupe sold T-shirts as a fundraiser so that they could go to summer camp. When the girls began their fundraiser, 600 people wanted their T-shirts. They were actually short by 210 T-shirts, so the troupe ordered more. They raised the price in hopes of earning more profit, but when the price increased, the demand went down. Use the given information to analyze what happened with the fundraiser.
What happens when the quantity is above the equilibrium point?
Answers
Answer:
If the quantity is above the equilibrium point, there is an oversupply.
Step-by-step explanation:
The demand and supply curves intersect at a point called the equilibrium point. At this point, the price and quantity of equilibrium are determined. If we increase the price of the products, there is a decrease in the quantity demanded.
If demand and supply are perfectly elastic, when the price increases, the quantity demanded decreases proportionally. Given this, we can deduce that the collection of funds did not vary from what they would have obtained by selling the rest of the t-shirts at the same price.
If the quantity is above the equilibrium point, there is an oversupply.

Mr Nickelson tells the class that they double the least common denominator for 1/2 3/5 and 9/15 to find the number of the day what number is the number of the day
Answers
Given fractions are [tex] \frac{1}{2} ,\frac{3}{5} ,\frac{9}{15} [/tex]
To find the least common denominators of the given fractions, we need to find the least common multiple (L.C.M.) of the numbers given in denominators i.e. 2, 5, and 15.
Finding the LCM of 2, 5, and 15 :-
2 = 1 x 2
5 = 1 x 5
15 = 3 x 5
So least common multiple of 2, 5, and 15 would be (1 x 2 x 3 x 5) = 30.
Hence, common denominator would be 30.
The teacher tells us to double the common denominator to find the answer that is the number of the day.
So we need to double the value of common denominator i.e. 2 x 30 = 60.
It means that 60 is the number of the day.
Hence, 60 is the final answer.
The number of the day is 4.
Explanation:Least common denominator for 1/2 3/5 and 9/15
To find the least common denominator (LCD) for fractions, we need to find the smallest multiple that is common to all the denominators.
For 1/2, 3/5, and 9/15, the denominators are 2, 5, and 15 respectively.
To find the LCD, we need to double the smallest denominator, which is 2, resulting in an LCD of 4.
Therefore, the number of the day is 4.

100 is not a reasonable estimate for the operation 915.25 divided by 88.22, as the actual answer is approximately 10.37. While estimates don't provide exact numbers, the difference here is too great for 100 to be considered reasonable, depending on the level of accuracy needed.
Explanation:In mathematics, estimation is commonly used when you do not need the exact answer, but rather a ballpark number close to the actual value. The student's question revolves around whether 100 is a reasonable estimate for the operation 915.25 divided by 88.22. We can check this by performing the actual division: 915.25 / 88.22 equals approximately 10.37. Although this is not exactly 100, it is within an order of magnitude which might make the estimate reasonable depending on the context. Therefore, as a quick estimate, 100 might not be suitable for high-precision contexts.
It's important to understand how estimates work. Their value is not in providing exact numbers, but in giving a quick understanding of a situation, especially when the exact numbers are complex or cumbersome. Here, however, the difference between the actual result (10.37) and the estimate (100) is quite significant, which suggests that 100 might not be a reasonable estimate in this case, depending on the level of accuracy needed.

Answers
1.8p = 5.04
p = 5.04/1.8
p = 2.8
it cost $2.80 per pound
Estella buys 1.8 pounds of walnuts for a total of $5.04. She solves the equation 1.8p=5.04 to find the price p in dollars of one pound of walnuts. what does one pound of walnuts cost?
Solution: Let the cost of one pound of walnuts= $p
So, The cost of 1.8 pound of walnuts=$1.8p
Whereas, The cost of 1.8 pound of walnuts=$5.04
So, 1.8p=5.04
Now, To solve for p, Let us isolate p
To isolate p, Let us divide by 1.8 on both sides
[tex] \frac{1.8}{1.8} p=\frac{5.04}{1.8} [/tex]
On dividing 5.04 by 1.8, we get 2.8
[tex] \frac{1}{1} p=\frac{2.8}{1} [/tex]
So, p=2.8

Cereal is packaged in a box shaped like a rectangular prism with a base 7.5 inches by 2 inches and a height of 10 inches. Manufacturing each box requires 10% more cardboard than the box's surface area. How much cardboard is needed to make each box?
Answers
We have then:
A = 2 * ((L * h) + (L * w) + (h * w))
Where,
L: long
w: width

Substituting the values:
A = 2 * ((7.5 * 10) + (7.5 * 2) + (10 * 2))
A = 220
Then, "Manufacturing each box requires 10% more cardboard than the box's surface area"
Ar = 220 * 1.10
Ar = 242
242-220 = 22

A six sides dice rolls twice. What is the probability that the first roll is a even number and the second roll is a number greater than 4?
Answers
EXPLANATION
For a six sides dice:
Possible numbers are: 1, 2, 3, 4, 5, and 6
Total of 6 possible numbers
Possible even number outcomes are: 2, 4, and 6
Total of 3 outcomes out of 6 possibilities
Probability that the roll is a even number, p(A) = 3/6
p(A) = 3/6 = 1/2
Possible outcomes greater than 4 are: 5 and 6
Total of 2 outcomes out of 6 possibilities
Probability that the roll is a number greater than 4, p(B) = 2/6
p(B) = 2/6 = 1/3
The probability that the first roll is a even number and the second roll is a number greater than 4 = p(A and B)
p(A and B) = p(A) x p(B)
p(A) = 1/2
p(B) = 1/3
p(A and B) = p(A) x p(B)
= 1/2 * 1/3
= 1/6

The orientation of a figure changes when it is reflected across a line while its shape and size stay consistent, creating a mirror image with symmetry relative to the line of reflection.
When a figure is reflected across a line, its orientation changes, whereas the shape and size of the figure remain the same. The Law of Reflection implies that each point of the figure maintains its distance from the line of reflection but on the opposite side, creating a 'mirror image' or symmetric counterpart. This mirror image aligns with the original figure if an imaginary line were drawn perpendicular to the mirror (line of reflection) at each point, these perpendiculars would be equal in length on both sides. This reflection transformation is an example of a linear transformation, preserving the straightness of lines and parallelism of parallel lines.

Answer:
Eder needs 15 cookies and 5 brownies for every 10 plates he makes.
Step-by-step explanation:
In order to know hoy many cookies and brownies Eder needs for 10 plates, given the fact that he needs 6 cookies and 2 brownies for every 4 plates, we need to perform the following calculation:
6C + 2B = 4X (plates)
6/4C + 2/4B = X
1.5C + 0.5 B = X
So, as we can see, 1.5 cookies and 0.5 brownies are needed for every plate. To know how many of those are needed for ten plates, we ned to multiply those numbers by 10.
1.5 x 10 = 15
0.5 x 10 = 5
Eder needs 15 cookies and 5 brownies for every 10 plates he makes.

Answers
The measure of central tendency most affected by the 10th value of 1.5 mph is the mean. The median and mode are relatively unaffected since both involve the frequency of terms, and having a tenth term that is far below (like 1.5) will not affect it much as compared to if it was near the rest of the values (like anything below 39).
The new SD including the tenth car involves adding the deviation of (-43.5)^2 to the sum of 579, which gives 2471.25. Dividing by 9 (there are now 10 data points) and taking the square root gives the new SD of 16.6.
