Answer: 67.5 cm
Step-by-step explanation:
Jason has 4 lengths of ropes
first is 
second is 
Third is ![0.3\ m\approx 30\ cm\quad [\text{1 m = 100 cm}]](https://tex.z-dn.net/?f=0.3%5C%20m%5Capprox%2030%5C%20cm%5Cquad%20%5B%5Ctext%7B1%20m%20%3D%20100%20cm%7D%5D)
fourth is ![0.5\ ft\approx 6\ in.\approx 15\ cm\quad [\text{1 ft=12 in.}]](https://tex.z-dn.net/?f=0.5%5C%20ft%5Capprox%206%5C%20in.%5Capprox%2015%5C%20cm%5Cquad%20%5B%5Ctext%7B1%20ft%3D12%20in.%7D%5D)
the total length of rope is the sum of four lengths
That's a question about the Pythagorean Theorem.
We use the Pythagorean Theorem to find the value of one side in a right triangle.
This theorem says that:
- <em>a</em> is the hypotenuse (It's the opposite side the right angle).
- <em>b</em> and <em>c </em>are cathetus (They're the adjacent sides the right angle).
Okay, now, let's go to solve this problem! In our figure, we have two cathetus. Their values are 10 and 7 and we have to find the value of <em>x </em>(the hypotenuse). Let's change this information in that formula.
Therefore, the value of <em>x </em>is 
.
I hope I've helped. :D

Ryan's data collection is true that Ryan did a survey he asked about qualitative data.
Given that Ryan called every school in the district to find out if they had a recycling program.
We know that there are two types of data:
Quantitative data deals with numbers and things that we can count or measure such as dimensions such as height, width, and length.
Qualitative data relating to characteristics and descriptions cannot be counted or measured, but are observable by their qualities such as smell, taste, and color.
If we ask for quantitative data, the survey will be quantitative. Data recycling means the quality of the data available.
They can ask for a yes or no answer, as in the Ryan investigation.
Hence, the correct statement about Ryan's data collection is: Ryan conducted a survey in which he asked about qualitative data.

Answer:
120 ft
Step-by-step explanation:
The distance the gravel covers is the total distance times the percentage that the gravel covers
We know the gravel covers 66 ft and the percentage is 55%
distance gravel = total distance * percentage
66 = total distance * 55%
66 = total distance *.55
Divide each side by .55
66/.55 = total distance *.55/.55
120 = total distance
