Answer:
Question 1: 76 dollars. ($76)
2. 1/5
3. 1/19
4. 1/5
Step-by-step explanation:
QUESTION 1:
228 (the amount Mrs. Nicci had) divided by 3 (children) is equal to 76
228/3 = 76
QUESTIONS 2, 3, AND 4.
2. Find the greatest common divisor (GCD). the GCD of 14 and 70 is 14. Then, divide the numerator and denominator by 14.
14/14 = 1
70/14 = 5
WHICH EQUALS 1/5!!
3. Find the greatest common divisor (GCD). the GCD of 5 and 95 is 5. Divide both the numerator and denominator by 5.
5/5= 1
95/5= 19
WHICH EQUALS 1/19!!
4. Find the greatest common divisor (GCD). the GCD of 12 and 60 is 12. So (like we have been doing for the whole part of this question), divide both the numerator and denominator by 12, which is the GCD.
12/12 = 1
60/12 = 5
WHICH EQUALS 1/5!!
Hope this helped.. I think this is like one of the longest Brainly answers I've recently had to type lol
I have attached a diagram of the triangle described.
We can use any of the trigonometric functions to find angle x. Remember, SOH CAH TOA. And since we're finding the angle, we'll need to use an inverse trigonometric function. For this problem, I'll be using the sine function.
sin(x) = 84 / 85
x = sin^-1(84/85)
x = 81.2026 degrees (feel free to round to however many places you need)
Hope this helps!! :)
How To Find Inverses:
1. First, replace f(x) with y . ...
2. Replace every x with a y and replace every y with an x .
3. Solve the equation from Step 2 for y . ...
4. Replace y with f−1(x) f − 1 ( x ) . ...
5. Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
