Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
----> by angle addition postulate
substitute the given values
Well you have to start of by finding the circumference of the tire, which you can do with the equation 2πr. If the radius is 1.2 feet, you just plug this into the equation to get 2.4π, which we will round to 7.5. After 10 rotations, you should've traveled approximately 75 feet
7*4=28
7-4=3
so the width is 4 feet and the length is 7 feet
Answer:
Step-by-step explanation:
Given
Represent Boys with B and Girls with G
Required
Find the probability or having 1 boy 2 girls
Since the order is not important, the probability is calculated as follows;
Substitute 
for P(B) and P(G)
<em>Hence, the fractional probability is </em>

Answer:
side of square is 2-x
Step-by-step explanation:
Area of the square is side * side or side ², so the expression for the side has to be square root of area
A = 4 -4x + x²
It should be recognized that 4 -4x + x²is a special product ( 2-x)² because this is a perfect square trinomial
side of square is 2-x
