Answer:
A. 36
Step-by-step explanation:
Because the two angles at the bottom of both the triangles are congruent, the two triangles are similar. Therefore, the corresponding side lengths of the triangles must be proportional to each other
if the area of a triangle is hb/2,
(with h=length of height, b=length of base)
the height of the first triangle is:
25 = 10h/2
50 = 10h
h=5
you can write ratios representing the proportions of the two triangles:
5/x = 10/12 (with x=height of second triangle)
x=6
then find the area of the second triangle with the height (6) and base (12)
(6*12)/2 = 36
The number of people who took ride in the big ferris wheel at a fair can be calculated by proper dimensional analysis. This can be done through the equation below,
n = (number of minutes)(rate at which the chair passes the exit platform)(number of persons per chair)
Substituting the known values to the equation,
n = (30 minutes)(1 chair / minute)(2 persons / chair)
n = 60 persons
Answer: 60 persons
Hi!
First of all, we can look and see that these sqaure roots are the same, so it's easy to add.
In square roots, if the number INSIDE the square root is the same, it stays that way for the answer .
So the equation is 9(square root) 5 + 4(square root) 5.
The numbers out the sqaure root can just be added. So 9+4 = 13.
Lastly just attach the sqaure root onto the 13
Final answer should be 13(square root)5
***use the actual symbol in place of (sqaure root)
I hope this helps!
