The length of the hypotenuse of a 30 60 90 triangle is 11. What is the perimeter?
1 answer:
Answer:
Perimeter of the triangle is units
Step-by-step explanation:
Given a degree angled triangle
Let us calculate the length of side opposite the 30 degree angle
hypotenuse
units
length of side opposite the 60 degree angle
units
The perimeter of a triangle is equal to the sum of length of all three sides
Thus, the perimeter of this degree angled triangle is
units
Thus, the perimeter of the triangle is units

<h3>Option 1</h3>- C(x) = 25x + 50
- C(8) = 25*8 + 50 = $250
- As per table, the rate of change is $30 per 2 hours.
- So 8 hours will cost
- $190 + $30 = $220
As we see the second option is cheaper so we should hire the Master Remodeling
Answer:
597.25 m
Step-by-step explanation:
We need to find 77% of 775.66 m.
It can be calculated as follows :
So, 77% of 775.66 m is equal to 597.25 m.
Answer:
25%
Step-by-step explanation:
Let v, t be the current average speed and the time taken to reach the school respectively.
As distance = speed x time, so,
distance, d=vt...(i)
Let V be the new average speed in order to to take 20% less time than t.
So, time taken with speed V = t-20% of t = t- 0.2t= 0.8t
As distance is constant, so
d= V(0.8t)= 0.8Vt
hBy using equation (i), we have
0.8Vt = vt
0.8 V = v
V= v/0.8=1.25v
Therefore, the percentage increase in the average speed =
=25%
Hence, the percentage increase in the average speed is 25%.
