1 section is 640 acres.
(1/8)·(1/2)·(1/8)·(640 acres) = 5 acres
_____
The property description actually seems a bit bogus. While 1/128 of 1 section is 5 acres, it is not clear exactly which 1/128 of the section is being specified. This appears to be a math problem, rather than a surveying problem.
Usually quarter-sections are further divided into quarters. Any half piece will be specified according to a cardinal direciton (N, E, S, W), and any quarter piece will be specified using two cardinal directions (NE, SE, SW, NW). An eighth piece would need three directions for its specification, but would typically be described in terms of a half of a quarter (N half of NE quarter, for example), rather than one-eighth.
Step-by-step explanation:
(4y-y)(9+4x+3y)
36y+16xy+12y^2-9y-4xy-3y^2
collect like terms
36y-9y+16xy-4xy+12y^2-3y^2
=27y +12xy+9y^2
<span>c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.</span>
Step-by-step explanation:
a+(a+60)=760
a=adult tickets
a+60=student tickets
a+a+60=2a+60
2a+60=760
-60 -60
2a=700
÷2. ÷2
a=350
350 adult tickets
Answer:
it would be b since a number is being taken away from 8
