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:
The expression represents the total amount that Alexi needs to pay is T= 1.02A , where T is total amount and A is restaurant bill.
Step-by-step explanation:
Given : Alexi’s restaurant bill is $58, and he wants to leave a 20 percent tip.
We have to find the expression represents the total amount that Alexi needs to pay.
Since, Alexi's restaurant bill is $ 58.
Also, she want to leave 20 % tip
So 20 % of her restaurant bill is 20% of 58
Thus, her total amount is 58 + 11.6 = $ 69.6
Alos, in expression it can be represented by
Total Amount to be paid = Amount + 0.02(Amount)
Mathematically, written as
T = A+ 0.20A
T= (1+0.02)A
T= 1.02A
The expression represents the total amount that Alexi needs to pay is T= 1.02A , where T is total amount and A is restaurant bill.
