Answer:
Step-by-step explanation:
The original price was 43 dollars
The new price is 55/100 * 43
The new price is 2365/100
The new price is 23.65 dollars
2365 came from multiplying 43 * 55 which is 2365
Answer:
The answer is option B
Step-by-step explanation:
To find cos 45° we must first find the adjacent and the hypotenuse
Let the adjacent be x
Let the hypotenuse be h
To find the adjacent we use tan
tan ∅ = opposite / adjacent
From the question
the opposite is 9
So we have
tan 45 = 9 / x
x tan 45 = 9
but tan 45 = 1
x = 9
Since we have the adjacent we use Pythagoras theorem to find the hypotenuse
That's
h² = 9² + 9²
h² = 81 + 81
h² = 162
h = √162
h = 9√2
Now use the formula for cosine
cos∅ = adjacent / hypotenuse
The adjacent is 9
The hypotenuse is 9√2
So we have
cos 45 = 9/9√2
We have the final answer as
<h3 /><h3>cos 45 = 1 / √2</h3>

The answer is the last option: 
Explanation:
1. You have that the equation of the line is:
Where 
is the slope of the line and 
is the intercept with the y-axis.
2. Therefore, you must find .
3. Then, you must substitute the points given in the problem and the slope into the equation of the line and solve for , as following:
Answer:
12 + 24 = 2(6 + 12)

much appreciated if this were marked brainliest <3
It wants you to find how much money you will spend a year at each separate gym. That way you can find out which one is cheaper. Once you’ve done that, you need to find how many days it would take for both gym’s cost to be the same after so many days.
