For these problems, the this number is this percent of what number ones, turn the percent into a decimal.
Do this by moving the decimal two places to the left.
0.25 is the decimal.
Now divide the whole number by the decimal.
60/0.25=240
60 is 25% of 240
X is amount of plates 10lbs and f(x) is the function
Tan(x) = opp/adj
tan(30°) = 9/n
n x √3/3 = 9
3n x √3 = 27
3√3n = 27
√3n = 9
n = 9/√3
It could be 55% is that an option?
3^2/3^4
To find the answer, we can use this equation:
a^m / a^n = a^m - n
We can now just use 2 - 4, which equals -2.
Now we have 3^-2
3^-2 in decimal form is 0.11111, which equal to 1/9
