recall that
sin(x) = cos(90-x)
therefore
cos((2/3)x + 20) = cos(90 - [2x - 10])
(2/3)x + 20 = 100 - 2x
2x + (2/3)x = 80
divide through by 2
x + (1/3)x = 40
(4/3)x =40
4x = 40*3
4x = 120
x = 30
since it is a right angled triangle, the angles are 30, 60 and 90
Answer: A=40 B=50

4. Suppose 4x + 9 pizzas were sold on Monday and 3x - 4 pizzas were sold on
Tuesday. What is the total number of pizzas sold?
Answer:
7x+5 pizzas were sold.
Step-by-step explanation:
4x and 3x combine to make 7x. Since we are adding 9 and also subtracting 4, they cancel out to be adding only 5. Combine this to make 7x+5.

1. 800 tickets were sold for a Rock Music
Concert with a total revenue of $7500. If
adult tickets were sold for $12 and students
tickets were sold for $8. How many of each
type of ticket were sold?
I will set it up for you only.
Let a = adult tickets
Let s = student tickets
Here is your system of equations:
a + s = 800
12a + 8s = 7500

1. {MCC.7.G.6) The area of the base of an 8-inch-tall cylinder is 36T
square inches. What is the volume of this cylinder (rounded to the
nearest whole cubic inch)?
Answer:
[tex]Volume = 144in^3[/tex]
Step-by-step explanation:
Given
[tex]Base\ Area = 36in^2[/tex]
[tex]Height =8[/tex]
Shape: Cone
Required
Determine the volume
Volume is calculated using:
[tex]Volume = \frac{1}{3}\pi r^2h[/tex]
Where
[tex]Base\ Area = \pi r^2 = 36[/tex]
[tex]Height = h = 8[/tex]
So:
[tex]Volume = \frac{1}{3} * 36 * 8[/tex]
[tex]Volume = 144in^3[/tex]

A stadium is divided into 4 sections. Each section is laid out in rows.
Section
Number of Rows
A: 42
b:50
c:36
D:16
There are 8 seats in each row of Section C. Which of the following equations can you use to find the number of seats in Section C? Select all
that apply.
S = 8 + 36
S = 36 + 36 + 36 + 36 + 36 + 36 + 36 + 36
S = 42 + 50 + 36 + 16
S = 8 x 36
S = 8 x 42
Part B
How many seats are in Section C? Enter your answer in the box.
Answer:
Both S=8x36 and S=36+36+36+36+36+36+36+36 apply
There are 288 seats in section C

Answer:
1. The applicable theorem is the midsegment theorem
y = 5 cm
Step-by-step explanation:
The given quadrilateral MATH is an isosceles trapezoid,
The bases of the isosceles trapezoid are
b₁ = [tex]\overline{MA}[/tex] and b₂ = [tex]\overline{HT}[/tex]
The median of the isosceles trapezoid = [tex]\overline{LV}[/tex]
MA = 3·y - 2
HT = 2·y + 4
LV = 8.5 cm
The midsegment theorem states that the median of a trapezoid is parallel to the bases of the trapezoid and is equal to half the length of the sum of the bases of the trapezoid
The median of a trapezoid = (1/2)×(b₁ + b₂)
Therefore, we have;
The median of the isosceles trapezoid, LV, given as follows;
LV = 8.5 = (1/2)×((3·y - 2) + (2·y + 4))
LV = 8.5 = (1/2)×(5·y + 2) =
2 × 8.5 = (5·y + 2)
17 = 5·y + 2
∴ 5·y = 17 - 2 = 15
y = 15/3 = 5
y = 5 cm

A bird feeder is in the shape of a cylinder. It has a volume of about 100 cubic inches. It has a radius of 2 inches. What is the approximate height of the bird feeder? Use 314 for pi.
Answer:
8 in approx
Step-by-step explanation:
Given data
volume = 100 cubic inches
radius= 2 inches
The expression for the volume of a cylinder is given as
v=πr^2h
substitute
100= 3.14*2^2h
100= 12.56h
h= 100/12.56
h=7.9 in
Hence the height is 8in approx

Answer:
Step-by-step explanation:
71+42+BAD=180
BAD=67
Answer:
m<BAD = 67
Step-by-step explanation:
The given figure is a parallelogram. Consecutive angles in a parallelogram are supplementary, meaning that their angle measures sum up to 180 degrees. Using this, one can say,
m<D + m<A = 180
Substitute,
m<ADB + m<BDC + m<A = 180
71 + 42 + m<A = 180
113 + m<A = 180
Inverse operations,
113 + m<A = 180
-113 -113
m<A = 67
Throughout Lewis Carroll's book, Alice's Adventures in Wonderland, Alice's size changes. Her normal height is about 50 inches tall. She comes across a door, about 15 inches high, that leads to a garden. After drinking a potion, Alice's height changes to 10 inches so she can visit the garden. How tall would the door have been in Alice's normal world? Justify your answer and provide mathematical evidence.
Answer:
The answer is 75 inches.
Step-by-step explanation:
If Alice is 10 inches, she is 2/3 as tall as the door. At her regular height, to be 2/3 as tall as the door the door would have to be 75 inches high.
Please give me the correct answer.Only answer if you're very good at math.Please don't put a link to a website.
Answer:
there are infinitely many solutions
LEFT SIDE/ LEFT EQUATION: if you multiply 1 and (b + 14) together, the result becomes the numerator of the fraction (with 2 being the denominator).
Once you do that, you will notice that both sides/both equations are exactly the same.
Thus, if you put in ANY number for variable b, the solution of both sides/both equations will always be the same and work.
The answer is: "There are infinetly many solutions"
