Answer:
B.
Step-by-step explanation:
42600-25800=16800
16800/15=1120
42600*x=100*1120
x=112000/42600=2.62%
Answer:
1
Step-by-step explanation:
Three side lengths that meet the requirements of the triangle inequality will form exactly one triangle.
_____
The triangle inequality requires the sum of the short sides be at least as long as the long side. Here, we have 3 + 4.69 = 7.69 > 7, so we satisfy the triangle inequality.
The side lengths can be arranged in clockwise or counterclockwise order, least to greatest. Each triangle is a reflection of the other, so they are considered to be the same triangle (congruent).
Answer:
C. 
Step-by-step explanation:
We proceed to solve for 
by the Pythagorean Theorem:
(1)
There are two different solutions:
, 
A solution of is considered realistic when the length of every side of the triangle is a not negative number.
The only realistic set of solutions is for 
, and the radius of the circle is represented by the line segment 
: 
And the area of the circle (
) is calculated from the following formula:
The correct answer is C.
Answer:
D
Step-by-step explanation:
A cube is something that has the same length on all sides, so therefore, multiplying one of the side lengths by 3 gets you the answer.
