Heather has a rectangular yard, she measures it and finds out it is 24 1/2 feet long by 12 4/5 feet wide. She wants to know how many square feet of sod she will need to cover her yard. How much did will she need and if each square inch of sod cost 65 cents how much will she pay to cover her yard?
Answer: $2,446.08
Step-by-step explanation:
Lets convert the length and width into decimal form so it's easier to understand.
24 1/2= 24.5
12 4/5= 12.8
Now we must multiply to get the area. 24.5x12. 8= 313. 6 ft
Each square inch costs .65 so we must multiply .65 by 12 to see how much a foot costs. 12x0.65= 7.8
Now that we know how much each foot cost lets multiply 313.6 by 7.8. 313.6x 7.8= $2446.08

The total cost of these 2 pens is 60p.
Work out the total cost of 5 of these pens.
Give your answer in pounds.
Answer:
£1.50
Step-by-step explanation:
If two pens equal 60p
do 2 x 2 = 4
4 pens equal £1.20
to get 1 pen do 60p divided by 2
which equals 30p
now add £1.20 and 30p
Peter bought 8 lemons for 6$ Each lemon was the same price.
Answer: Each lemon costs $0.75 cents (seventy five cents)
Step-by-step explanation:
0.50 x 8 is the same as "half" of 8. This is $4. That is too low so.. 0.75 cents
6 ÷ 8 = 0.75
Each lemon costs $0.75 or 75 cents.
The circumference of a circle is 7π m. What is the area, in square meters? Express your answer in terms of π
Answer:
[tex]12.25\pi\,\,m^2[/tex]
Step-by-step explanation:
Given: Circumference of a circle = [tex]7\pi\,\,m[/tex]
To find: Area of a circle in terms of [tex]\pi[/tex]
Solution:
Let r denotes radius of a circle.
Circumference of a circle = [tex]2\pi r[/tex]
[tex]7\pi=2\pi r\\7=2r[/tex]
Divide both side by [tex]\pi[/tex]
[tex]3.5\,m=r[/tex]
Area of a circle = [tex]\pi r^2[/tex]
Put [tex]r=3.5\,\,m[/tex]
[tex]=\pi (3.5)^2\\=12.25\pi\,\,m^2[/tex]
Answer:
A ≈ 3.9
Step-by-step explanation:
How to solve
Using the formulasA=πr2
C=2πr
Solving for AA=C2
4π=72
4·π ≈ 3.8993
Therefore, the circle in square meters in the nearest tenths is A ≈ 3.9
is the relation a function?
Answer:
Yes, each x-value is paired with exactly one y-value (no more than that)
Domain: x = -2, x = 1, x = 4, x = 7
Range: y = -3, y = 5, y = 6
No, the inverse is not a function, the x value of 6 would be paired with two y values (-2 and 7)

Determine the length of the line segment with the end points at (9, 6) and (-12, 6).
Answer:
Step-by-step explanation:
You are given two points whose y values are the same. There is no need to use the distance formula. The x values alone will give you the length of the line.
to get to the y axis you have to go 12 units to the right.
To get from the y axis to 9, you have to go 9 more units to the right.
The total is 9 + 12 = 21
If you insist to see this done with the formula, it would look like this.
d = sqrt( y2 - y1)^2 + (x2 - x1)^2 )
y2 = 6
y1 = 6
x2 = -12
x1 = 9
d = sqrt ( (6 - 6)^2 + (-12 - 9)^2 )
d = sqrt( 0 + ( -21 )^2 )
d = sqrt( 441)
d = 21 the same thing you got just be reasoning it out.
The first method works only if either both xs are the same or both ys are the same.

Mary reduced the size of a painting to a width of 3.3 in what is the height if it was originally 32.5 in tall and 42.9 in wide?
Answer: 2.5 in
Step-by-step explanation:
From the question, we are informed that Mary reduced the size of a painting to a width of 3.3 in even though the original width was 42.9 in wide. This shows that the size of the painting was 3.3/42.9 = 1/13
Therefore, the height of it was originally 32.5 in will be:
= 1/13 × 32.5
= 2.5 in
Therefore, the height is 2.5 in.

This does not make sense to me please explain and answer. will give 30 points and brainliest!!! PLEASE HELP ME!!
Answer:
C = 39
Step-by-step explanation:
From the question given above, the following data were obtained:
A = 2x + 108
B = x + 33
C =?
Next, we shall obtain an expression for C. This can be obtained as follow:
A + B + C = 180 (sum of angles in a triangle)
2x + 108 + x + 33 + C = 180
2x + x + 108 + 33 + C = 180
3x + 141 + C = 180
Make C the subject by rearranging
C = 180 – 141 – 3x
C = 39 – 3x
Next, we shall determine the value of x. This can be obtained as follow:
A = 2x + 108
B = x + 33
C = 39 – 3x
A + B + C = 180
2x + 108 + x + 33 + 39 – 3x = 180
2x + x – 3x + 108 + 33 + 39 = 180
3x – 3x + 180 = 180
3x – 3x = 180 – 180
3x – 3x = 0
x(3 – 3) = 0
x(0) = 0
x = 0
Finally, we shall determine C. This can be obtained as follow:
C = 39 – 3x
x = 0
C = 39 – 3(0)
C = 39 – 0
C = 39
Which of these statements are correct about two parallel lines in a coordinate plane? Select three that apply.
If they are each translated 7 units to the left, they will remain parallel.
If they are each reflected across the line y = x, they will remain parallel.
If they are each rotated 180° about the origin, they will not remain parallel.
If they are each reflected across the x–axis, they will not remain parallel.
If they are each rotated 270° about the origin, they will remain parallel.
If they are each translated 9 units down, they will not remain parallel.
Answer:
If they are each rotated 180° about the origin, they will not remain parallel.
If they are each translated 7 units to the left, they will remain parallel.
If they are each rotated 270° about the origin, they will remain parallel.
Step-by-step explanation:
I got them!!!!!!!!!!!!!!!!
If they are each rotated 180° about the origin, they will not remain parallel, If they are each translated 7 units to the left, they will remain parallel and If they are each rotated 270° about the origin, they will remain parallel are true statements.
What is Coordinate Geometry?Coordinate geometry (or analytic geometry) is defined as the study of geometry using the coordinate points.
Parallel lines are coplanar infinite straight lines that do not intersect at any point.
Among the given statements the following are true.
If they are each rotated 180° about the origin, they will not remain parallel.
If they are each translated 7 units to the left, they will remain parallel.
If they are each rotated 270° about the origin, they will remain parallel.
Hence, If they are each rotated 180° about the origin, they will not remain parallel, If they are each translated 7 units to the left, they will remain parallel and If they are each rotated 270° about the origin, they will remain parallel are true statements.
