Answer:
122in^2
Step-by-step explanation:
A= 10x10x3.14 = 314in^2
Ar= 12x16= 192in^2
Asr= 314-192= 122in^2
The equation is 3.50x=31.50
The answer is 9
Answer:
so it should be a,c,e, and b
Step-by-step explanation:
49s square root is 7 and 7 is an integer so check.
7 is a whole number check
7 is rational check
and 7 is a real number check.
For a one-to-one function, f(x) = f(y).
So, lets find f(x) and f(y).
We know,
f(x) = (x - 2)³ + 8
Now,
f(y) = (y - 2)³ + 8
Now, we said earlier, for a function to be one-to-one, f(x) = f(y).
Therefore,
f(x) = f(y)
(x - 2)³ + 8 = (y - 2)³ + 8
(x - 2)³ = (y - 2)³
x - 2 = y - 2
x = y
Since we got x = y, we know for every x, there is one and only one y. Therefore, the function is one-to-one function.
So first we need to get rid of that naughty sales tax so we need to divide 30.45 by 1.05 since 30.45 is 105% of the pre-tax price. We get the answer of 29 and subtract 12 from 29 since the long fleece socks cost 12 bucks and we get 17 dollars. Since there are 2 pairs of regular songs we divide 17 by 2 and get 8.5
So the regular socks cost $8.50
Checking work 8.5*2=17
12+17=29
1.05*29=30.45
