Answer:
60%
Step-by-step explanation:
3/5 is 60%
If the original price was 'p', the new price would be 'p - 10%p' or 'p - 0.1p'. We know this is equal to 305, so 'p - 0.1 p = 305' would be the equation.
The side length ratios of an isosceles right triangle are 1-1-
. So,
the length of a leg would be equal to the length of the hypotenuse divided by the square root of 2.
Using pythagorean theorem (c is the hypotenuse, a and b are the legs)
c²=a²+b²If the triangle is isosceles, two side lengths must be equal. In the case of a right triangle, the legs must be equal in length. So, b=a.
c²=a²+a²c²=2a²a²=c²/2a=c/a≈c/1.414
Answer:
340%
Step-by-step explanation:
1980s = 5 months of very hot weather
1990s = 22 months of very hot weather
What is the percent increase in hot weather months from the
1980s to the 1990s?
Percent increase = (22 months - 5 months) / 5 months × 100
= 17 / 5 × 100
= 3.4 × 100
= 340%
Percent increase in hot weather months from the 1980s to the 1990s is 340%
