Without any calculations it's evident it can't be neither B (both numbers are even, so they're divisible by 2) nor C (the numbers end in 0 and 5, so they're divisible by 5).
A.

Both numbers have a factor of 3, so they're not relatively prime.
That means it must be D. But, let's check it.

Indeed, those two numbers are relatively prime.
Answer:
x = 7.3
Step-by-step explanation:
When solving for missing sides using angles, use trig functions.
We have the angle 63° to use.
We are given the hypotenuse of the triangle, as well as the side adjacent to the angle, so we can use the cos function.
Cos T = (adjacent side)/(hypotenuse)
Here we know 'T' and the hypotenuse, so plug them in and solve
Cos 63° = x/16
(16)Cos 63° = x (multiply both sides by 16 to isolate 'x')
7.263847996 = x (use your calculator to solve the left side)
7.3 = x (rounded to the nearest 10th)
Answer:
yes, because when you "raise a number to power" you're multiplying the number by itself, and the power represents how many times you do so.
I hope this answers your question
Let's solve this problem step-by-step.
STEP-BY-STEP EXPLANATION:
In order to find the price at which the store owner sells the cell phone, we must first establish by how much the price is changing.
As the problem states that the price of the cell phones is marked up by 25 percent, we must simply find 25 percent of the original price which the cellphones were purchased at and then add the amount to the original price.
Essentially this means we will do the following:
Let selling price = x
Let original price purchased at = $40
Let mark up = 25% = 0.25
x = Original price purchased at × ( 1 + mark up )
x = 40 × ( 1 + 0.25 )
x = 40 × 1.25
x = $50
FINAL ANSWER:
Therefore, the price which the store owner sells the cell phones at is $50.
Hope this helps! :)
Have a lovely day! <3
