Answer:
x = 9
Step-by-step explanation:
Both the triangles are similar, so the corresponding sides are also similar.
That is,
12 / 8 = x / 6
Cross multiply,
x * 8 = 12 * 6
8x = 72
Divide 8 on both sides,
x = 72 / 8
x = 9
Answer:
Step-by-step explanation:
Area = 0.5(base)(height)
= 0.5(16.9)(10.4)
= 87.88 sq ft
Answer:
50%
Step-by-step explanation:
assuming you are talking about one coin flip (because you didn't specify) you have a 50% chance to land on tails
Answer:
The perimeter of rectangle is 
Step-by-step explanation:
Let
x------> the length of rectangle
y----> the width of rectangle
we know that
The area of the constructed figure is equal to

so
-----> equation A
-----> equation B
substitute equation B in equation A

using a graphing calculator to resolve the quadratic equation
the solution is

Find the value of x

Find the perimeter of rectangle
The perimeter of rectangle is equal to

<span> s = -16t^2 + 64t + 3
v = -32t + 64
the maximum height occurs when v = 0:
-32t + 64 = 0 when t = 2 sec
the maximum height is
s = -16(2^2) + 64(2) + 3 = 67 ft
the range is [ 3, 67] </span>
