Step-by-step explanation:
using Pythagoras a²+b²=c²
HOWEVER you know the hypotenuse
so it's rearranged to either c²-b²=a² or c²-a²=b²
so 13²-11²
so 169-121
this makes 48
square root 48 is 6.90 inches
this rounds up to <u>7</u><u> </u><u>Inches</u>
Answer:
94.5%
Step-by-step explanation:
Percent decrease can be represented as
[original price] * percentage = [new price]
When trying to find the percentage, you can manipulate the equation by dividing both sides by the original price to get:
percentage = [new price] / [original price]
In this case, this is represented by 192300/203400, or 94.5%
