Answer:
D
Step-by-step explanation:
Cosine is adjacent / hypotenuse, so 12/13
SOLUTION:
a ) Write an equation in standard form that models your earnings.
8x + 6y = $114
b ) You worked 10 hours as a hair washer. How many hours did you work as a host?
8x + 6y = $114
8x + 6 ( 10 ) = 114
8x + 60 = 114
8x = 114 - 60
8x = 54
x = 54 / 8
x = 27 / 4 hours
x = 6.75 hours
x = 6 hours and 45 minutes
Answer:
B. f(g(x)) = 7x + 27
Step-by-step explanation:
We have, f(x) = 7x+13 and g(x) = x+2.
So, the function f(g(x)) is obtained by substituting the function g(x) = x+2 in f(x) = 7x+13,
i.e. f(g(x)) = f(x+2)
i.e. f(g(x)) = 7 × (x+2) + 13
i.e. f(g(x)) = 7x + 14 + 13
i.e. f(g(x)) = 7x + 27
Thus, f(g(x)) = 7x + 27
Hence, option B is correct.
Answer:the answer is 1/5
Step-by-step explanation:
let
x-------> walnuts that Mario eats in a week
y-------> walnuts that Yolanda eats in a week
we know that
x=2y-------> equation 1
y=6*7-------> y=42 walnuts
substitute the value of y in equation 1
so
x=2*42-----> x=84 walnuts
therefore
the answer is
Mario eat in a week 84 walnuts
