From their location in the diagram, what are two possible values for n and m?
A diagram with concentric circles. The outer circle is labeled rational numbers, with an m. The middle circle is labeled integers. The smallest is labeled whole numbers, with an n.
m=3.3, n=−14
m=−2, n=−62
m=6, n=−43
m=−38, n=12
Concentric circle simply means the circle that has a common center or axis.
What is a concentric circle?Your information is incomplete. Therefore, an overview of concentric circles will be given. The region between two concentric circles is known as the annulus.
An example of concentric circle is the ripple that is made when a pebble is dropped inside water. The formula for a concentric circle is given as:
(x - h)² + (y - k)² = r².
In conclusion, when two circles have same center, they're called concentric circles.

Ed and Fay shared £330 in the ratio 7 : 4
Ed gives Fay some of his money.
Fay now has the same amount as Ed.
How much does Ed give Fay?
Ed must give Fay a total of £45 for both to have the same amount of money.
How to solve ratioTotal = £330
Ed = 7Fay = 4Total ratio = 7 + 4= 11
Ed share = 7/11 × 330
= £210
Fay share = 4/11 × 330
= £120
For Ed and Fay to have the same amount of money, their share must be exactly half of £330.
That is, they must each have £330/2
= £165
Fay:
£165 - £120 = £45
Therefore, Ed must give Fay a total of £45 for both to have the same amount of money.

Suppose Gina can spend a maximum of $150 for fabric for her project. To the nearest tenth, how many yards of each type of fabric could she buy? Write your answer as an inequality. Show your work.
The length restrictions for each fabric are described by the following inequalities:
Batik0 ≤ n ≤ 16.67 yd
Linen0 ≤ n ≤ 18.75 yd
How to determine an inequation related to the quantity of yards bought
In this question we notice that the quantity of yards of fabric (n) is directly proportional to the cost (C). First, we should derive the formulae based on the information contained in tables:
BatikC = 9 · n (1)
LinenC = 8 · n (2)
Now we proceed to determine the maximum possible amount of fabric:
Batikn = 150/9
n = 16.67 yd
Linenn = 150/8
n = 18.75 yd
The length restrictions for each fabric are described by the following inequalities: (Please notice that length is a positive real variable)

During the movie norma ate 3 handfuls of snack mix and brennan ate 1 3/8 handfuls how much more did norma eat?
1.625 more handfuls
Explanation:To start, we know that Norma ate 3 handfuls
n (Norma) = 3
Next, we learn that Brennan ate 1 and 3/8 handfuls. 3/8 converted into decimal form is 0.375, so Brennan ate 1.375 handfuls
b (Brennan) = 1.375
To figure out the difference between the two, you do Brennan's 1.375 and subtract it from Norma's 3.
An equation for this (if it helps) would be
n - b = x
To solve, substitute the values to find x
In conclusion, Norma ate 1.625 more handfuls than Brennan
♡ Ok now have a great day, you are doing amazing! I'm so proud of you! ♡Find the zeros of the function p(x) = -9x^2 + 1
Answer:
Zeros: 1/3 and -1/3
Step-by-step explanation:
You can solve this for the zeros by using the factoring method:
p(x) = (-3x-1)(3x-1)
Then, you take each factored equation and set it equal to zero:
-3x-1=0
3x-1=0
Then, solve for zero:
-3x=1 x=-1/3
3x=1 x=1/3
Your zeros are 1/3 and -1/3.

Answer:
[tex](x - 2)^{2} + (y + \frac{5}{2} )^{2} = \frac{37}{4}[/tex]
Step-by-step explanation:
The standard form of the equation: (x-2)²+ (y + 5/2)² = 37/4 , center: (2, -5/2) and radius: (√37) / 4.
What is a circle?A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.
We have given the equation,
2x²+2y²-8x + 10y+2 = 0
Divide by 2,
x²+y²-4x + 5y+1 = 0
Arranging the terms to make a complete square of variable x and y.
x²+y²-4x + (2/2)5y+1+ 4 + 25/4 = 4 + 25/4
(x-2)²+ (y + 5/2)² = 37/4
This is the form of a circle.
Use this form to determine the center and radius of the circle.
(x−h)²+(y−k)²=r²
Match the values in this circle to those of the standard form.
The variable r represents the radius of the circle, h represents the x-offset from the origin, and k represents the y-offset from the origin.
r=(√37) / 4, h=2, k= -5/2
The center of the circle is found at (h,k).
Center: (2, -5/2)
Therefore, center: (2, -5/2), radius: (√37) / 4

What is the slope of the line 5y = 2x - 15?
Answer:
2/5x
Step-by-step explanation:
The equation of a line in slope intercept form:
y = mx + b, where m is the slope and b is the y-intercept.
1) Rearrange the terms so it matches y = mx + b. In this case, it is already rearranged.
5y = 2x - 15
2) Divide the terms by 5.
y = 2/5x - 3
Answer:
2/5 is the slope of the line 5y = 2x - 15
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept.
5y = 2x - 15
Divide both sides by 5.
y = 2/5x - 3
2/5 =m
2/5=slope

Find the surface area of the cylinder
Answer:
Surface area of the cylinder is 377 cm² (approximately)Step-by-step explanation:
Given :-
Radius of the cylinder = 6cmHeight of the cylinder = 4 cmTo find :-
Surface areaSolution :-
We know that,
Surface area of cylinder = 2πr(h + r)Substituting the required values,
➝ Surface area= 2 × 22/7 × 6 (6 + 4)
➝ Surface area = 264/7 (10)
➝ Surface area = 2640/7
➝ Surface area ≈ 377 cm²
Hence,
Surface area of the cylinder is 377 cm² (approximately)After refering the diagram given in attachment, we clearly came to knew that the radius of the cylinder is 6 cm and height of that cylinder is 4 cm.
Radius (r) = 6 cm Height (h) = 4 cmAs we know that total surface area of cylinder is calculated by the formula :
T.S.A. = 2πr (h + r)Where,
r is radius h is height Value of π is 22/7★ Putting the values in the formula :
>> T.S.A. = 2πr (h + r)
>> T.S.A. = 2 × (22/7) × 6 (6 + 4)
>> T.S.A. = 2 × (22/7) × 6 (10)
>> T.S.A. = 2 × (22/7) × 6 × 10
>> T.S.A. = 2 × (22/7) × 60
>> T.S.A. = (44 / 7) × 60
>> T.S.A. = 44 × 60 / 7
>> T.S.A. = 2640 / 7
>> T.S.A. = 377
★ Therefore,
Surface area is 377cm²When darryl and his family moved to the city, there were 133 retail stores. use the equation to predict what year darryl’s family moved to the city.
According to the information, the year Darryl and his family arrived in the city was 2001.
How to calculate the year that Darryl and her family moved to the city?To calculate what year Darryl and her family moved to this city, we need to replace the value of x with the year they moved and the result should be 133.
y = 11x + 12133 = 11x + 12133 - 12 = 11x121 = 11x121 ÷ 11 = x11 = xAccording to the above, 11 years passed from 1990 to the year in which Darryl and his family moved to the city, that is, the year 2001.
