Area of a Trapezoid, A = [(a+b)/2] · h
Where,
a and b are the respective bases of the trapezoid
h is the height of the trapezoid
a = 10
b = 7 + 10 + 10 = 24
h = 9
A = [(a+b)/2] · h
A = [(10 + 24)/2] · 9
A = [(34)/2] * 9
A = 17 * 9
A = 153 Units²
Answer:
The number of adults tickets and student tickets purchased is 5 and 3.
Given that,
Tickets to a movie cost $7.25 for adults and $5.50 for students.
A group of friends purchased 8 tickets for $52.75.
Here we assume the no of adult tickets and no of student tickets be x and y.
Based on the above information, the calculation is as follows:
7.25x + 5.50y = 52.75 .............(i)
x + y = 8
x = 8 - y..................(2)
Now put the x value in the equation (1)
So,
7.25(8-y) + 5.50y = 52.75
7.25 × 8 - 7.25y + 5.50y = 52.75
58 - 1.75y = 52.75
5.25 = 1.75y
y = 3
So,
x = 8 - 3
= 5
Therefore we can conclude that the number of adults tickets and student tickets purchased is 5 and 3.

X=10 and X=3/4 basically it’s whatever X equals to make the inside the parentheses equal zero. So if I were to plug 10 into the first parentheses you’d have 10-10 which equals zero. Also the zero has to the the opposite sign of what’s in the parentheses. So if -10 is in the parentheses then the zero has to be the opposite so positive 10.
Answer:
a tree was 5 meters tall. a person used a chainsaw to cut 1/4 of the tree. how tall is the tree now?
also, please don't copy the answer word for word.
Use sine cosine and tangent to find the answer. Sine=opposite/hypotenuse
Cosine= adjacent/hypotenuse tangent= opposite/adjacent. This should help you find your answers.
