Answer:
$515.35
Step-by-step explanation:
y-hat = 2.009x - 37.131
y-hat = 2.009(275) - 37.131
y-hat = 552.475 - 37.131
y-hat = 515.344
Therefore, the pizza parlor can expect a profit of $515.35 if it sells 275 pizzas.

I really need help lol...you get 81 POINTS!!!!!!!!!!!!!!!!!!
Answer:
area = 82 cm²
Step-by-step explanation:
The figure comprises a trapezoid, a triangle and a square.
Calculating areas of the three shapes separately and then adding them will give us the required area of the composite figure.
Area of square : (side)²
= (2)²
= 4 cm²
Area of triangle : ½ × b × h
= ½ × 3 × 12
= 3 × 6
= 18 cm²
Area of trapezoid : ½ × (a + b) × h
= ½ × (5+5) × 12
= ½ × 10 × 12
= 5 × 12
= 60 cm²
Now, area of the composite figure :
= 4 + 18 + 60
= 22 + 60
= 82 cm²
Answer:
82 cm²Step-by-step explanation:
If you exclude the square on the bottom, you have a trapezoid with bases of 5 cm and 8 cm and the height of 12 cm.
Its area is:
A = (5 + 8)*12/2 = 78 cm²Add the area of the square with sides of 2 cm:
A = 2*2 = 4 cm²Total area is:
A = 78 + 4 = 82 cm²Gigi earned $65 for 5 hours of gardening. She earned $90 for 9 hours of office work. Which statement correctly compares Gigi’s earning per hour for gardening and office work?
Answer:
Even though you did not add choices, she makes more gardening.
Step-by-step explanation:
65 / 5 is 13, so she makes $13 an hour while gardening.
90 / 9 is 10, so she makes $10 an hour while doing office work.

Help I need the answer dont send NO FILE only answer if you know it step by step explanation
Answer:
See below & see pic.
Step-by-step explanation:
To find where a point goes, start with the original point and see how many units it takes to get to the line of reflection in a path perpendicular to that line.
For example, H is 3 units from the line, so go 3 units past the line to find H'.
Do the same for the other points.
You get E'F'G'H' as shown in the figure below.

how to find the measure of the obtuse angle
Answer:
Measure of obtuse angle is 134 degrees
Step-by-step explanation:
these two angles are supplementary so they add up to 180
68x-2 +23x=180
91x-2=180
91x = 182
x = 2
plug in x
68 (2) -2 = 134
23 (x) = 46
what are the next two terms in the sequence?: 1, -2, 4, -8
Answer:
16 and -32Step-by-step explanation:
-2÷1 = -2
4÷(-2) = -2
-8:4 = -2
So this is a geometric sequence with a common ratio of -2
Therefore:
the 5th term: -8×(-2) = 16
the 6th term: 16×(-2) = -32

Verify that a + ( b + c) = (a + b) + c , a = (-12) , b = 4 , c = (-25)
Answer:
a + (b + c) = (a + b) + c
Step-by-step explanation:
a= (-12), b = 4, c = (-25)
[tex](12) + (4 + ( - 25)) = ( - 12 + 4) + ( - 25) \\ - 33 = - 33[/tex]
Answer:
GIVEN :-
a = -12b = 4c = -25TO VERIFY :-
a + (b + c) = (a + b) + cSOLUTION :-
Find the values of L.H.S. & R.H.S.
L.H.S. :-
Put all values in → [tex]\boxed{a+(b+c)}[/tex]
⇒ -12 + [4 + (-25)]
⇒ -12 + (4 - 25)
⇒ -12 + (-21)
⇒ -12 - 21
⇒ -33
R.H.S. :-
Put all values in → [tex]\boxed{(a+b)+c}[/tex]
⇒ (-12 + 4) + (-25)
⇒ -8 - 25
⇒ -33
CONCLUSION :-
L.H.S. = R.H.S.
⇒ a + (b + c) = (a + b) + c
A circle has diameter endpoints of A(5, 10) and B(-3,4).
What are the coordinates of the center of the circle?
0 (4, -2)
o(-11, -2)
O (13, 16)
o (1,7)
Answer:
(1,7)
Step-by-step explanation:
Hi there!
The center of the circle is located in the middle two diameter endpoints. To find the coordinates of the center of the circle, calculate the midpoint of the two endpoints A and B.
Midpoint: [tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex] where the two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points A(5, 10) and B(-3,4):
[tex](\frac{5+(-3)}{2} ,\frac{10+4}{2} )\\(\frac{5-3}{2} ,\frac{10+4}{2} )\\(\frac{2}{2} ,\frac{14}{2} )\\(1,7)[/tex]
Therefore, the center of the circle have coordinates of (1,7).
I hope this helps!

What is the biggest area of a quadrilateral you can fit in a circle that has a
circumference of 20π units? Show your work and a diagram to support your
answer
Answer: 200 square units
Step-by-step explanation:
Given
Circumference of the circle is [tex]20\pi[/tex]
Suppose r is the radius of the circle
The biggest area of a quadrilateral that can fit in a circle is of square.
Deduce the radius of the circle
[tex]2\pi r=20\pi\\r=10\ \text{units}[/tex]
Suppose the side of the square is a
from the figure, we can write
[tex]\Rightarrow a^2+a^2=(2r)^2\\\Rightarrow 2a^2=4r^2\\\Rightarrow a=\sqrt{2}r\\\Rightarrow a=10\sqrt{2}\ \text{units}[/tex]
Area of the quadrilateral is
[tex]\Rightarrow A=(10\sqrt{2})^2\\\Rightarrow A=100\times 2\\\Rightarrow A=200\ \text{square units}[/tex]
