Answer:
12.2 feet
Step-by-step explanation:
The key to this problem is trigonometry.
Imagine a right triangle. With a height, 10 ft (representing the tree's height), and a base of 7 ft (representing the horizontal distance to the worm).
Now the hypoteneuse length, or otherwise the distance from the worm is unknown.
So this is where we can use the pythagorean theorem.
here is the hypoteneuse length, and 
and 
are the other lengths of the triangle.
Since we know a and b we can solve for c.
But first we will square root both sides of the equation to get and not 
.
Now just plug in our values for a and b respectively. (It doesn't matter what number replaces a or b, just make sure you are replacing a and b with the 2 known values) Calculate.
Round to the nearest tenth.

Answer:
Interquartile range = 24
Step-by-step explanation:
First we need to put the sequence in order from lowest to highest.
0, 1, 3, 5, 21, 25, 45
5 is the median and then from 5 to 0 we need to find the lowest interquartile in between it which is 1.
Highest interquartile from 5 to 45 finding the middle will be 25.
Interquartile range = highest interquartile - lowest quartile
25-1 = 24

Answer:
In total, it sells 90 loaves.
Step-by-step explanation:
The number of loaves of bread sold is:
20 on Wednesday
25 on Thursday
On Friday, it does the same as Wednesday and Thursday combined. So 20 + 25 = 45.
How many total loaves does it sell?
20 + 25 + 45 = 90
In total, it sells 90 loaves.
