Amount of milk drunken: (4 children)(0.5 gall per week per child)
Multiply the result of the above calculation by ($2.89 / gallon):
4(0.5)($2.89) = $5.78 per week milk expenditure
C. (22,16)
Y=x-6
16=22-6
16=16
Answer:

Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the right triangle ABC of the figure, the tangent of angle C is equal to divide the opposite side to angle C (side AB) by the adjacent side to angle C (side BC)
so

substitute the given values

simplify

<span> (8^ -2)(4^4)(16^ -1)
</span>
<span>a^-x=(1/a^x)
</span>
<span> (4^4)/((8^2)(16))
"NOTE" </span><span>16^1=16
</span>
<span>4^4=256
8^2=64
256/((64)(16))=1/4
</span>
<span>convert 1/4 to a power of two
</span>
<span>(4) is 2
1/4=1/(2^2)
</span>
<span>1^2=1
(1/2)^2=(1/4)
</span>
<span>1/2 to the power of 2 is the answer
It would look like this
1/2²</span>
