10 in
10 in
Answer:
Surface area is the total area of the faces of a three-dimensional shape.
A square can not have a surface area since it's two dimensional. If you meant the area of a square then the formula is:
A = a²
a = length of side
8 in = 64 in
10 = 100 in

42. Tell whether x and y are proportional.
43. What number is 60% of 35?
44. 27 is what percent of 75?
Just do 42 and 44
Using proportions, it is found that:
42. x and y are not proportional.
43. The number 21 is 60% of 35.
44. The number 27 is 36% of the number 75.
How to verify if two variables are proportional?Two variables, x and y, will represent a proportional relationship if the ratio between them is always the same.
From the table, the ratios are given as follows:
6/4 = 1.5.8/6 = 1.25.Different ratios, hence the variables x and y are not proportional.
Percentage of a numberTo find the percentage of a number, the decimal equivalent of the percentage is multiplied by the number.
The decimal equivalent of a percentage of 60% is:
60/100 = 0.6.
Hence the percentage of 35 is calculated as follows:
0.6 x 35 = 21.
The percentage that the number 27 represents of the number 75 is given by the division of 27 by 75 multiplied by 100%, hence:
27/75 x 100% = 36%.

The equivalent expression of the given expression is [tex]\frac{g^1^5}{8h^6}[/tex].
What is inequality?
Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).
Consider the given expression, [tex]\frac{(2g^5)^3}{(4h^2)^3}[/tex]
Using the rule, [tex](a^m)^n = a^m^n[/tex]
So, [tex]\frac{(2g^5)^3}{(4h^2)^3} = \frac{8g^1^5}{64h^6}[/tex]

Using inequality, we know that Mia needs to buy 41 sets of knives.
What is inequality?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made. Relationships between two expressions that aren't equal to one another are known as inequalities. Inequalities are represented by the symbols, >, <, ≤, ≥, and ≠ has the meaning "7 is greater than" (or "is less than 7," when read left to right).So, the number of sets of knives Mia could buy:
There are currently 248 knives in the restaurant.There are 10 knives in each set that is for sale, so there are 10s knives added to each set.If s sets are purchased, there will be a total of, T = 248 + 10s.At least 657 knives are required by the restaurant, so:
T ≥ 657The difference is:
10s + 248 ≥ 657Now, solve as follows:

The angle measures in this problem are given as follows:
1. Angle SVT: 79º.
2. Angle BEC: 65º.
Angle SVTAngles SVT and SVR are vertical, meaning that they have the same measure, hence we can find the value of y as follows:
8y - 33 = 5y + 9
3y = 42
y = 42/3
y = 14.
Hence the measure of the angle SVT is of:
m<SVT = 5y + 9 = 5(14) + 9 = 79º.
Angle BECThe two angles given in this problem are also vertical, meaning that we can solve for x as follows:
5x - 10 = 3x + 40
2x = 50
x = 50/2
x = 25º.
Then the bottom angle is:
3 x 25 + 40 = 115º.
The bottom angle is supplementary with angle BEC, hence we can find the measure of angle BEC as follows:
115 + m<BEC = 180
m<BEC = 180 - 115
m<BEC = 65º.

Only 20 percent of the spectators left the contest discontented. If 6000 spectators left the contest contented,
how many left discontented?
There are 24000 spectators left the contest discontented.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We have been given that Only 20 percent of the spectators left the contest discontented.
If 6000 spectators left the contest contented, then the contest left discontented are;
The spectators left the contest contented = 6000
20/ 100 x D = 6000
D = 6000 x 100/20
D = 30000
Now the contest left discontented are;
80 percent = 80/100 x 30000

a pharmaceutical company knows that five percent of all users of a certain drug experience a serious side effect. a researcher examines a sample of 200 users of the drug. a. what is the probability of finding between 8 and 12 cases with side effects? (round final answer to 4 decimal places.) b. what is the probability of finding more than 16 cases with side effects? (round final answer to 4 decimal places.)
Using the normal distribution, the probabilities are given as follows:
a. Between 8 and 12 cases with side effects: 0.582 = 58.2%.
b. More than 16 cases with side effects: 0.0174 = 1.74%.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given by the equation presented below:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure X is above or below the mean of the distribution, depending if the z-score is positive or negative.From the z-score table, the p-value associated with the z-score is found, and it represents the percentile of the measure X in the distribution.The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with [tex]\mu = np, \sigma = \sqrt{np(1-p)}[/tex].The parameters for the binomial distribution in this problem are given as follows:
p = 0.05, n = 200.
Hence the mean and the standard deviation of the approximation are given as follows:
E(X) = np = 200 x 0.05 = 10.[tex]\sqrt{V(X)} = \sqrt{np(1 - p)} = \sqrt{200(0.05)(0.95)} = 3.08[/tex]For item a, using continuity correction, the probability of between 8 and 12 cases with side effects is the p-value of Z when X = 12.5 subtracted by the p-value of Z when X = 7.5, hence:
X = 12.5:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (12.5 - 10)/3.08
Z = 0.81
Z = 0.81 has a p-value of 0.7910
X = 7.5:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (7.5 - 10)/3.08
Z = -0.81
Z = -0.81 has a p-value of 0.2090.
0.7910 - 0.2090 = 0.582 probability.
For item b, the probability of finding more than 16 cases with side effects is one subtracted by the p-value of Z when X = 16.5, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (16.5 - 10)/3.08
Z = 2.11
Z = 2.11 has a probability of 0.9826.
1 - 0.9826 = 0.0174 = 1.74% probability.
