Answer:
The answer is x = 25%
Step-by-step explanation:
84 represents 100% of the questions.
63 represents x% of the correct answers.
x = (63x100)/84
x = 6300/84
x = 75% correct answers.
percentage of the wrong answers:
100% - 75% = 25%
Answer:
Step-by-step explanation:
We can write an relationship for this as:

Answer: 1.27 in
Step-by-step explanation:
100= 16 (3.14 (2.5/2)^2 x t)
t= 1.27 in
I am assuming the -3 is an exponent.
y⁻³ and 5⁻³
If the exponent is a negative number, it simply means that the number is a denominator with 1 as the numerator.
y⁻³ is 1/y³
5⁻³ is 1/5³ = 1/125
The number is still raised to its exponential power but its placement is different.
5³ would be 125 or 125/1. It would be the numerator with 1 as the denominator.
