Answer:
33.3%
Step-by-step explanation:
Let's say the percent change is x%. Then the equation is:
30 + x% * 30 = 40
Subtract 30 from both sides:
x% * 30 = 10
Divide by 30:
x% = 10/30 = 1/3
Remember that % simply means "out of 100", so:
x/100 = 1/3
Multiply both sides by 100:
x = (1/3) * 100 = 33.3%
Answer:
Any collection of lengths (a, b, c) which do not satisfy the triangle inequalities.
Step-by-step explanation:
Any collection (a, b, c) which do not satisfy the triangle inequalities. The inequalities:
a + b > c
b + c > a
a + c > b
You will need to test all of your options on the three inequalities above. If any one of the three fails, the collection won't work.
Answer:
68%
Step-by-step explanation:
85 divided by 125 = .68 * 100 = 68
Answer: x=4
Steps: (I am assuming your question has a typo in it and by "c" you meant "x")
The rational expression equals zero
only when the numerator equals 0 (the denominator cannot ever be zero):
and that happens only for x=4
