Set an equation:
4/5=x-3/x+1
cross multiply
5x-15=4x+4
x=19
Width: 16 cm
Length: 20 cm
Find the perimeter and the area:
Perimeter: 16+16+20+20=72
Area: 20•16=320
Ratio: 320:72
Simplify the ratio:
40:9
Answer: The ratio of the area to the perimeter is 40:9.
The number is 2/9 hope that helps!
Answer:
80%
Step-by-step explanation:
Find 44/55 and multiply the result by 100%: (0.8)(100%) = 80% (completed)
C = (a^2 + b^2)^1\2
c = (6^2 + 8^2)^1\2
c = (36 + 64)^1\2
c = (100)^1/2
c = 10
hope this helped, blessings!
