To start solving the exercise, we obtain as data:
π = 3r = 3 ftWe apply as a formula:
A = πr², whereA = areaπ = pir = radiusWe apply the formula and solve:
A = π r²A = 3× (3 ft)²A = 3 × 9 ft²A = 27 ft²Therefore, the area of the circle is 27 ft².
Answer: 27ft²
Step-by-step explanation: Soln:
Given that,
π=3
Radius(r)=3ft.
We have,
A = π r²
A = 3* (3)²
A=3*9
A=27ft²

9² or 9^2
Step-by-step explanation:Because the base is the same on the top and the bottom which is "9", you would either add or subtract the top and bottom exponent based on the arithmetic symbol used.
Because the arithmetic symbol division sign is used, you subtract the top exponent by the bottom giving you the answer nine to the power of two.

Answer:
[tex]\textsf{b.} \quad 3x+5y=2[/tex]
Step-by-step explanation:
Define the given points:
[tex]\textsf{let}\:(x_1,y_1)=(4,-2)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(-1,1)[/tex]
Use the slope formula to determine the slope of the line:
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1-(-2)}{-1-4}=\dfrac{1+2}{-1-4}=-\dfrac{3}{5}[/tex]
Use the point-slope formula to determine the equation of the line.
[tex]\implies y-y_1=m(x-x_1)[/tex]
Substitute the found slope and point (4, -2):
[tex]\implies y-(-2)=-\dfrac{3}{5}(x-4)[/tex]
[tex]\implies y+2=-\dfrac{3}{5}(x-4)[/tex]
Multiply both sides by 5:
[tex]\implies 5(y+2)=-3(x-4)[/tex]
Expand the brackets:
[tex]\implies 5y+10=-3x+12[/tex]
Add 3x to both sides:
[tex]\implies 5y+10+3x=-3x+12+3x[/tex]
[tex]\implies 3x+5y+10=12[/tex]
Subtract 10 from both sides:
[tex]\implies 3x+5y+10-10=12-10[/tex]
[tex]\implies 3x+5y=2[/tex]

Which expression is equivalent to 56x-28y + 42?
a.) 8(7x - 3y + 6). b.) 7(8x + 4y +6z)
c.) 7(8x - 4y + 6)
Answers
Answer:
Letter c
Step-by-step explanation:
You are distributing the 7 to each term in the parentheses.
7(8x) is 56 x
Here is the tricky part. You can think of it a couple of ways:
7(-4y) = -28y a positive times a negative is a negative.
or 7(4y) = 28 , but then remember that you are subtracting so it will become -28
7(6) = 56
56x - 28y +42
Answer:
c.) 7(8x - 4y + 6)
Step-by-step explanation:
if we solve 7(8x-4y+6), we get;

The median is the middle number in an ordered data set. Since the number of date in the table is a even number, both 75 and 76 is the middle number. To find the median of an set of data that has an even number of sets, you just add the 2 middle numbers together and divide by 2. So like:

151/2=75.5
75.5 is the median but its not listed in the table, so A.

There are 5 blue socks in Josh’s drawer. After he removes 3 non-blue socks, the probability to pick a blue sock at random becomes . How 1/7 many non-blue socks were in Josh’s drawer originally?
Answers
Answer: There is 5 non blue sock in Josh's drawer
Step-by-step explanation:
The denominator shows the total of nonblue and blue socks. So there are 7 non-blue and blue socks in the drawer after he removes 3 non blue socks.To find how many non-blue where in the drawer originally you need to find how many non blue are in the draw after removing the three. So you subtract 7 from 5 which gives you 2. So there are 2 non-blue socks in the drawer after removing the three. Now you need to find how many non-blue were there before he removed the three. So add the 3 non blue socks that he removed to the two that were there after which gives you five.

A would be incorrect because the problem is asking what the area of the stamp would be. In order to find area, we multiply length and width by each other. The given equation we initially had shows division, and would therefore be incorrect. B would be incorrect because although the equation has the correct evaluation symbol, the formula for identifying length would be L = A / W, which means length equals area divided by width. Because the area is 1/4 in this problem, the expression used for evaluation would be 1/4 divided by 1/5. D is incorrect because, like B, the evaluation expression would be 1/4 divided by 1/5.
Your final answer: Because C is the only problem that gives us a corresponding expression to the initial expression, C is the correct answer. If you need extra help, let me know and I will gladly assist you.
Answer:
Step-by-step explanation:
(A)length of a stamp=1/5foot
wide of a stamp=1/4foot
area of the stamp=?
area of the stamp=length of a stamp *wide of a stamp
=1/5*1/4
=1/20square foot
(B)an area of the room=1/4 square meter
width of the room=1/5meter
length of the room=?
an area of the room=width of the room*length of the room
1/4 =1/5 * length of the room
1/4 = length of the room/5
5/4 =length of the room
length of the room =5/4=1 1/4(C)the area of the canvas=1/5square yard
width of the canvas=1/4 yard
length of the canvas=?
an area of the canvas=width of the canvas*length of the canvas
1/5 = width of the canvas*1/4
1/5 = width of the canvas/4
4/5 =width of the canvas
width of the canvas= 4/5
(D)length of the rectangular course=1/5mile
area of the rectangular course=1/4square mile
width of the rectangular course=?
an area of the rectangular course
=
width of the rectangular course*length of the rectangular course
1/4 =width of the rectangular course*1/5
1/4 =width of the rectangular course/5
5/4 =width of the rectangular course
width of the rectangular course=5/4

Answers
Answer: 32
Step-by-step explanation:
The only numbers that can have 2 digits and two of which equal to five can only be:
3+2
2+3
4+1
1+4
So the numbers are: 41,14,23, and 32.
41-9=32
14-9=5
23-9=14
32-9=23
Since the question is asking for the number who’s difference is the reverse of one of the numbers. The only possible answer is 32 because 32-9= 23. (23 is the reverse of 32)
3+2 is equal to 5
32 - 9 is equal to 23 witch is the reverse of 32
