<h3>Answer: 442 square cm</h3>
==================================
Explanation:
Use the area of a trapezoid formula, along with the given area, to solve for the height of the trapezoid (h)
A = h*(b1+b2)/2
741 = h*(23+34)/2
741 = h*28.5
741/28.5 = h
26 = h
h = 26
The height of the trapezoid is 26 cm
------------
Now we can find the area of triangle BCD. Its height is also 26 cm.
area of triangle = (1/2)*base*height
area of triangle BCD = (1/2)*BC*h
area of triangle BCD = (1/2)*34*26
area of triangle BCD = 442
You should divide 87 by 114 for the precent of people. 76% with an margin either way is between 80% and 72%.
The answer is 1 or 2 cause if it is in abc order it can be purple blue green
Answer:
B) 72
Step-by-step explanation:
The n-th term of an arithmetic sequence An = a1 + (n - 1) d
Given :
a28 = 423/4 and d = 5/4
So
a28 = a1 + (28 - 1)5/4
Now plug in a28 = 423/4
423/4 = a1 + 27(5/4)
a1 = 423/4 - 27(5/4)
= 423/4 - 135/4
a1 = (423-135)/4
a1 = 288/4
a1 = 72
Thank you.
Answer:
pi / 4
Step-by-step explanation:
Circumference = 2pi(R)
pi = 2pi(R)
pi / 2pi = R
1/2 = R
Area= pi(R)^2
A = pi(1/2)^2
A= pi/4
