Poster standard dimension: 8.5 inches by 11 inches
Both length and width of the poster may vary 1/20%
∴ length and width may vary 1/20 % = 0.05% = 0.0005
∵ Area = Width * Length
∴ Area = 8.5 * 11 = 93.5 in²
Smallest acceptable area for one poster:
Width: 8.5 * (1 - 0.0005) = 8.49575 in.
Length: 11 * (1 - 0.0005) = 10.9945 in.
∴ The smallest area = 8.49575 * 10.9945 = 93.4065 ≈ 93.407 in².
The answer is A, he can use the spa 3 more times. Hope I helped!
Answer:

Supplementary angles are angles that add up to 180 degrees. Oftentimes, we see that supplementary angles are on a straight line, of which is also equal to 180 degrees.
x + y = 180
x + 116 = 180
x = 64 degrees
Hope this helps!! :)
Based on the graph which models the function at x = -2 (see attachment), the corresponding y-value is y = 3.
<h3>What is a function?</h3>
In Mathematics, a function can be defined as a mathematical expression which can be used to define and show the relationship that exist between two or more variables in a data set.
In this scenario, there are several values (points) on the given linear graph expressed as a coordinate (x, y). Hence, the x-values on the x-axis is directly proportional to the y-values on the x-axis.
By critically observing the graph which models the function at x = -2 (see attachment), we can logically deduce that the corresponding y-value is three (3).
