Chris cut a rope into two pieces. One piece was 11.36 meters long and the other piece was 13.46 meters long. About how long was the rope before Chris cut it? Round each length to the nearest tenth to estimate the total length of the original piece of rope before Chris cut it.

Answers

If you would like to know about how long was the rope before Chris cut it and you would like to round each length to the nearest tenth to estimate the total length of the original piece of rope, you can calculate this using the following steps:

11.36 meters = 11.4 meters
13.46 meters = 13.5 meters

11.4 + 13.5 = 24.9 meters

Result: The rope was 24.9 meters long (before Chris cut it) - rounded to the nearest tenth.

24.82 meters long. Is the answer to your question.

Step-by-step explanation:

Find f(x)=x 4/7+9/14 can someone help me solve this as a improper fraction

Answers

the expression in the form of an improper fraction is: $f(x) = (14x^(4/7) + 9) / 14$ . To find f(x) when $f(x) = x^(4/7) + 9/14$ , we need to combine the terms on the right-hand side and simplify the expression.

Step 1: Combine the terms on the right-hand side:

$f(x) = x^(4/7) + 9/14$

Step 2: To express $x^(4/7)$ as an improper fraction, we raise x to the power of 4/7. Remember that the denominator of a fraction represents the root (in this case, the 7th root) and the numerator represents the power (in this case, 4).
