Answer:
111.4556
Step-by-step explanation:
Perimeter = 18 + 25 + 18√2 + 43
Perimeter = 86 + 18√2
Perimeter = 86 + 18(1.4142)
Perimeter = 86 + 25.4556
Perimeter = 111.4556
86+18
Use the properties of 45-45-90 triangles to get a side length of 18 for the 2 legs of the isosceles triangle. Then add 43+18, which is the shorter length of the rectangle, +25, which is the longer edge, +18. The answer is now 86+18.
0.6 km/hr
Speed downstream: 13/5= 2.6 km/hr
Speed upstream: 7/5= 1.4 km/hr
Therefore, Velocity of current is: 1/2 (2.6-1.4) km/hr = 1/2(1.2) km/hr
9/15=3/5
so 3/5 is equivalent fraction of the 9/15
1/10 or 10%
1/4 x 2/5 = 1/10 (10%)
what percent discount is it?
Answer: x=9
3x+8=35
Subtract 35-8=27
3x=27
27/3=9
x=9
