Answer:
≈13degrees
Step-by-step explanation:
It is given that Two cities A and B are 1400km apart and lie on the same N-S line. The latitude of city A is 23 Degrees. Then,
Using the formula, 
where s is the distance between the two cities and r is the radius of the earth,thus substituting the values, we get
⇒
Therefore, 
⇒
⇒
Thus, the latitude of B is=12.53 degrees≈13degrees
When adding or subtracting fractions, there is one big rule: make sure the denominators are the same first!
As long as the denominators (the numbers on the bottom of the fraction) are the same, you can get an answer by adding the numerators (the numbers on top) and keeping the denominator the same.
********Here's an example********
2/3 + 3/3
First, make sure the denominators are the same. Since the number on the bottom of each fraction is the same, namely 3, we can proceed without worry.
Now add the numerators. The numbers on top are 2 and 3. 2 + 3 = 5.
The final answer is 5/3. We added together the numerators to get the top number, and kept the denominator the same for the bottom number.
***************************************
Try adding 3/4 and 4/4 together on your own now before you look ahead.
To get the answer, let's follow the process.
Make sure the denominators match. They do, so we can proceed.
Add the numerators. 3 + 4 = 7.
Keep the denominator the same. The denominator is 4.
Your answer is 7/4!

Express y in terms of x in the given equation.
y = 3x + 15
Substitute the given value of x in the modified equation,
y = 3(1/3) + 15
y = 1 + 15 = 16
Thus, the matching value of y given the value of x is 16.
Answer:
Step-by-step explanation:
- 5/6 - 3/4 =
- 10/12 - 9/12 =
- (10 - 9)/12 =
- 1/12
Answer:
a. 
b. 
c. 
Step-by-step explanation:
In a, the -1 means inverse of f(x). To find the inverse, you rewrite the equation in terms of x and y. You replace the x with y and y with x. Then you solve for y.
In b, all you have to do is plug in -9 into f(x).
In c, you plug in -9 into inverse function f.
