Which calculation can be used to find the value of y in the equation y3 = 27

1 answer:

6 0

You just divide each side of the equation by three so you'll get $y = 9$

Edit: I believe you wrote the equation wrongly. If it was $y^3 = 27$ , then you cubic root both sides and get $y = 3$ .

We have been given that a tree that measured $3\frac{3}{4}$ feet tall was planted. A hundred years later, the tree is now $25\frac{1}{2}$ feet tall. We are asked to find the number of times times is tree now taller than it was when the school first opened.

To solve our given problem, we will divide present length of tree by length of tree when it was planted as:

$25\frac{1}{2}\div 3\frac{3}{4}$

First of all we will convert mixed fractions into improper fractions.

$25\frac{1}{2}\Rightarrow \frac{25\times 2+1}{2}=\frac{50+1}{2}=\frac{51}{2}$

$3\frac{3}{4}\Rightarrow \frac{3\times 4+3}{4}=\frac{12+3}{4}=\frac{15}{4}$

$\frac{51}{2}\div \frac{15}{4}$

Now we will convert our division problem into multiplication problem by flipping the 2nd fraction as:

$\frac{51}{2}\times \frac{4}{15}$

Cancel out common factors:

$\frac{17}{1}\times \frac{2}{5}$

$\frac{17\times 2}{1\times 5}$

$\frac{34}{5}=6\frac{4}{5}$

Therefore, the tree is $6\frac{4}{5}$ is taller now than it was when the school first opened and option A is the correct choice.

Answer:

37.62 degrees + 47.87 degrees = 85.49 degrees

Step-by-step explanation:

For this question we are trying to find the "absolute value" between these 2 numbers, because one of the numbers are negative and the other one is positive, we are going to add both of them together. That is how we got 85.49. In a different equation, we might have done something different.
