Answer:
13/20
Step-by-step explanation:
First 1/4 of 20 is 16
Then you minus it by the 3= 13.
So it is left with 13
Answer:
One side is 6 (bottom of triangle) and two sides are 8 (two main sides of the triangle)
Step-by-step explanation:
The reason this is is because two sides of a regular triangle are the same while one is not. (The bottom of the triangle) So, the bottom is shorter than the sides.
Compound Interest = 
where P - Principal
r - rate of interest
n - number of years
So, for 5 years, at 6% rate of interest, for the principal 12,000, the compount interest will be
= 24000
Amount = Principal + C.I.
= 12000 + 24000
= 36000
Hence, after 5 years, the amount will be $36,000 approximately.
Answer:
Unlike the previous problem, this one requires application of the Law of Cosines. You want to find angle Q when you know the lengths of all 3 sides of the triangle.
Law of Cosines: a^2 = b^2 + c^2 - 2bc cos A
Applying that here:
40^2 = 32^2 + 64^2 - 2(32)(64)cos Q
Do the math. Solve for cos Q, and then find Q in degrees and Q in radians.
Step-by-step explanation:
I depends on the problem i believe.
