Answer:
28 (length' unit)²
Step-by-step explanation:
- the area of all A rectangle is 4*8 =32
- The area of the missing portion of the rectangle is equal to the area of the triangle ½*(2)*(4)=4
- the area of this shape equal to
the area of all A rectangle - The area of the missing portion of the rectangle = 32 - 4 = 28 (length' unit)²
<h3>Y
ou have the correct answer</h3><h3>Interest rate = 21.5%</h3>
===============================================
Work Shown:
i = P*r*t .... simple interest formula
i = simple interest
i = 2075-1000 = 1075
P = 1000 = amount borrowed (principal)
r = unknown interest rate
t = 5 = time in years
So,
i = P*r*t
1075 = 1000*r*5
1075 = 5000r
5000r = 1075
r = 1075/5000
r = 0.215
r = 21.5%
Answer:
0.1536
Step-by-step explanation:
The computation of probability that the building failure will occur over its life is shown below:-
P(building failure) is

now we will solve the above equation
= 0.18 - 0.0264
After solving the above equation we will get
= 0.1536
Therefore for computing the probability that the building failure will occur over its life we simply applied the above formula.
If

, then angle

is obtuse and triangle with sides a, b, c is obtuse triangle.
In an arbitrary triangle can be only one obtuse angle, and the side which lies opposite to the largest angle is the largest. Then since <span>angle

is opposite the side of length a</span> you can conclude that a>c and a>b.
The answer is c. 117 degrees
