Answer:
1.28 or 912/715
Step-by-step explanation:
sine= opposite side/hypotenuse
cos=adjacent/ hypotenuse
sine a= 12/13 using the Pythagorean Theorem and solve for the missing side. (which is the adjacent side)
cos a = 5/13
Do the same for sine b
cos b= 9.8/11
add both the cosine value
(5/13)+(9.8/11)=1.28 or 912/715 in fraction form
$2.88/12 = <u><em>$0.24 per ounce of body wash
</em></u><em></em>This can be solved by using a calculator.
Hope this helps!
Answer:
g(f(x)) = 1x² + 1
Step-by-step explanation:
We are given:
f(x) = x² - 1
g(x) = x + 2
And we want to find g(f(x)).
To do this, we substitute f(x) as x in x+2 (the expression that is equal to g(x)), as g(f(x)) is saying that f(x) is the value of x in g(x).
So, this will be:
g(f(x)) = x² - 1 + 2
Simplify
g(f(x)) = x² + 1
In your system, place 1 in front of x² - this is the coefficient of x², and also 1 after that - this is a constant.
Answer:
$880
Step-by-step explanation:
You are looking for the original price. What times 0.85 will equal 748. 748÷0.85 = 880. To check your work, 880 * 0.85 = 748.
Football is green, so 42% of the people like football.
210 people like football.
To find the total number of people surveyed, divide 210 by 42%:
210 / 0.42 = 500
500 people were surveyed.
