Answer:
The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.
The angle of C is 115 because it is a supplementary angle. A supplementary angle is an angle that has two angles with a sum of 180 degrees and 180 – 65 = 115

Find the interest earned from an investment of $14000 for 4 years at an interest rate of 6.85% compounded continuously. Round to the nearest cent.
Answers
Answer:
$4242
Step-by-step explanation:
Given data
Principal= $14000
TIme = 4 years
Rate= 6.85%
Let us find the final amount A
A=P(1+r)^t
substitute
A=14000(1+0.0685)^4
A=14000(1.0685)^4
A=14000*1.303
A=$18242
Hence the interest is
Interest= Final amount-Principal
=18242-14000
=$4242
Galvin bought 3/5 as many non-fiction books as fiction books from a book fair. He read 6 non-fiction books and 13 fiction books. He then had 3/4 as many non-fiction books left to read as fiction books. How many books did Galvin buy altogether?
Answers
Answer:
Let total non-fiction books = 3x
And total fiction books = 5x
After reading 6 non-fiction books, remaining non-fiction books = 3x-6
After reading 13 fiction books, total fiction books remaining fiction books = 5x-13
(3x-6)/(5x-13) = 3/4
Solving for x, we get x = 5
So total non-fiction books = 15 and fiction books=25
So total number of books bought = 40

divide by 4, 12, 21
Step-by-step explanation:
first, look at 20, and 5. How do you get there?
well, there are 2 possible ways.
20/4=5, or 20-15=5
we take it into the next pattern to get
44/4=11, and 44-15=29.
so now we know that the rule is to divide by 4
____________________________________________
36/4 = 12
84/4=21
Answer:
1. 36 / 4 = 9
2. 84 / 4 = 21
Rule: The input divided by 4. (I / 4 = O)
Step by Step explanation:
Look at the first input and output, what do you see? Well, 5 is a multiple of 20, but if 5 is the output, this means that instead of multiplication we're doing division. How many times does 5 go into 20? 4 times, so that's our rule, I / 4 = O. If we use this rule for the rest of the questions, you get the answer.

A pilot spots the airport at an angle of depression of 16°. The plane is flying at an altitude of 9,000 ft. What is the ground distance (distance along the ground) from the plane to the airport to the nearest foot
Answers
Answer:
[tex]31,387\:\text{ft}[/tex]
Step-by-step explanation:
We can form a right triangle using the plane, the airport, and ground and use basic trig for a right triangle to solve this problem.
In a right triangle, [tex]\tan\theta=\frac{\text{opp}}{\text{adj}}[/tex]. Therefore, we have the following equation, where [tex]x[/tex] is ground distance between the plane and the airport:
[tex]\tan 16^{\circ}=\frac{9,000}{x},\\x=\frac{9,000}{\tan 16^{\circ}},\\x\approx \boxed{31,387\:\text{ft}}[/tex].
