Answer:
-0.05
Step-by-step explanation:
This will become much easier if we can get the ugly decimal into a nice fraction form.
Start by recognising . This is almost correct except the fraction is out by some number of factors of 10 (because the 125 part is correct but the number of 0s isn't).
And hence we see that and now the cube root becomes easy to compute:
.
Advanced: You ask for <em>all </em>real cube roots. however the function is described as <em>bijective</em>. This means for all x, there is only one y corresponding to it. (And also for all y there is only one x corresponding to that). This means there can only ever be one cube root of any real number.
Answer:
10.125 feet.
Step-by-step explanation:
you can use the rule of three to answer this question, the data we have is:
inches feet
1 → 4 1/2
2 1/4 → x
tha last table just indicates what the problem tells us, that one inch is equal to 4 1/2 feet and we want to know how much in feet the 2 1/4 inches are.
For this we multiply the cross quantities:
the actual length of the kitchen is 10.125 feet.
Answer:
The area of the parallelogram is
Step-by-step explanation:
Remember that a mixed fractions are composed for a whole number, a numerator and a denominator. For example in the mixed fraction : 2 is the whole number, 1 is the numerator and 3 is the denominator.
If you want to convert to a improper fraction you need to multiply the whole number by the denominator and add to the numerator. The result will be the numerator of the improper fraction. The denominator remains the same.
1. Convert the mixed fractions in the improper fraction type, as follows:
2. Replace the data in the equation of a parallelogram
3. Convert the improper fraction in a mixed fraction
The area of the parallelogram is
