Answer: A. 13ft
Explanation:
a^2 + b^2 = c^2
a = 5, b = 12
5^2 = 25, 12^2 = 144
25 + 144 = 169
Square root of 169 = 13
Answer:
1.3 inches
Step-by-step explanation:
1. Determine what you already know in order to set up the equation:
1 inch = 100 miles
<em>x</em> inches = 130 miles
Solving for <em>x</em>
2. Set up the equation so both numerators are the same unit (In this case, both numerators are the mile values and both denominators are the inch values.)
= 
3. Cross multiply (Multiply the first fraction's numerator by the second fraction's denominator, and vice versa. It doesn't matter which number is on which side of the = sign.)
100<em>x</em> = 130
4. Divide each side by 100 to isolate the variable.
<em>x</em> = 1.3
84 is divided into 7 84/7 =12
and it is added to
9 divided into 3 9/3 =3
12+3=15
The answer is C Opposite Leg over the Adjesent Leg you can remember this because of SOH CAH TOA That means Sin = Opp/Hyp Cos = Adj/Hyp Tan = Opp/Adj
Formula for area of a trapezoid: a = [(b1 + b2)/2] x h
Applied:
a = [(11 + 14)/2] x 10
a = [25/2] x 10
a = 12.5 x 10
a = 125
The area of the trapezoid is 125 meters squared.
