Answer:
In terms of pi, the area is 25/π square inches.
Step-by-step explanation:
Circumference = 2πr
10 = 2πr
r=10/(2π)
A = πr^2
A = π(10/(2π))^2
A = π(100/4π^2)
A = 25/π square inches

Step-by-step explanation:
2.50x+3.00y=?
x=8 y=11
Answer:
The cost of popcorn per container = $2.50
The cost of bottle of juice each = $ 3.00
(Now multiple it)
2.50 x 8 = $20.00
3 x 11 = $33
(Now "+" the both answer that we multiple)
$20.00 + $33 = $53
(So we know how much she spend)
Therefore She spend $20 on popcorn per container and $33 on bottle of juice, so total she spend $53 for both popcorn and bottle of juice.

The length of a rectangle is represented by 9x - 5. The width of the rectangle is represented by 3.
Write two equivalent expressions that represent the Area of given rectangle.
Answer:
First factor the Area
Area = 18x2+12x+2
Factor out a 2
Area = 2(9x2+6x+1)
Factor this and you get
Area=2(3x+1)(3x+1)
Let L be Length and W be Width
Area=LW
and the Length is twice the Width so
L=2W
Area=2(3x+1)(3x+1) so
L=2(3x+1)
W=3x+1
This can also be written as if you distribute the 2
L=6x+2
W=3x+1

The top rectangle has a base b and a height h. The bottom rectangle has a base that is 1/3 of the length of the base of the top rectangle and a height that is 1/2 of the length of the height of the top rectangle. Devin writes the area of the smaller rectangle as the product 1/3b times 1/2h. Tracy rewrites this as 1/6bh. Which of the students’ expressions makes it easier to see how the areas of the rectangles are related? Explain.
Answer:
Tracy's explanation would be the simplest because 1\6 is half of one third she eliminated the need for an extra step if left the other way

Min draws an isosceles triangle.
Which attributes describe his triangle?
Choose each correct answer.
two obtuse angles
no angles the same measure
not a polygon
three sides
at least two sides the same length
closed figure
The attributes of the triangle are
a) three sides
b) at least two sides the same length
c) closed figure
What Is an Isosceles Triangle?A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.
In an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base. The angle opposite the base is called the vertex angle
The three types of Isosceles Triangles are :
Isosceles acute triangle
Isosceles right triangle
Isosceles obtuse triangle
Given data ,
Let the triangle be represented as ΔABC
While the third angle (opposite the base) may or may not be congruent to the other two angles in an isosceles triangle, the two angles opposite the equal sides are congruent.
Due to the fact that an isosceles triangle may only contain one obtuse angle at most, neither the statement "no angles the same measure" nor the statement "two obtuse angles" are true.
Hence , correct attributes that describe Min's isosceles triangle are:
At least two sides the same length
Three sides
Closed figure

Answer:
Option D) (136-2a) + ( 3a + 39) = 180
Step-by-step explanation:
As per provided information .
XQR is a straight line So, sum of all angles formed on straight line is 180° .
This Means
∠XOM + ∠MOR = ∠XQR
On putting the given value we obtain
(136 - 2a) + (3a + 39) = 180
So, the required option is (D) (136 - 2a) + (3a + 39) = 180
You can solve it further to get the value of a .

Which of the following examples would show a negative trend?
A. height and weight of students
B. test scores and height of students
C. outside temperature and heating bill
D. none of these
Explanation:
A negative trend is when one variable goes up and the other variable goes down (or vice versa).
As the temperature goes down, the heating bill is likely to go up. This is of course assuming the person(s) use the heat to stay warm rather than just solely rely on something like coats/blankets/etc.
As the temperature goes back up, there's little to no need for heating. So the heating bill will likely go down.
As the name implies, negative trend graphs have negative slopes for the regression lines.

Christopher buys 200 baseball cards to start a collection. He purchases 50 more baseball cards each week. Write an equation to represent the number of baseball cards (b) in Christopher’s collection after w weeks? How many cards does he have after 5 weeks?
Answer: equation is 200b + (50b · w). He will have 450 cards in 5 weeks.
Explanation: 50 baseball cards (b) times w then you add the cards he already has, which is 200. To answer question b, w becomes 5, so then it’s 50 baseball cards (b) times 5, which is 250b, then you add 200 (the cards he already has) and the answer is 450. Hope this helped!

[tex]\bold{x^2-2(x+5)}\\[/tex]
[tex]\bold{x^2-2x-10}[/tex]
Now, plug in the value of x:
