Because 6*6 = 36, we conclude that 36 is the only square number.
How to identify the square number?
A square number is a number that is equal to the product of a whole number and itself.
For example, the square numbers are:
2*2 = 4
3*3 = 9
4*4 = 16
5*5 = 25
6*6 = 36
7*7 = 49
etc...
From the given numbers: {5, 8, 15, 30, 36}
The only one that belongs to the above list is 36, that is the only square number, so that is the correct option.

Suppose that an individual has a body fat percentage of 15.9% and weighs 159. How many pounds of her weight is made up of fat? Round to the nearest tenth
Answer:
25.3 lb
Step-by-step explanation:
We can multiply the whole by the percentage to find the part. Since 15.9% is equal to 0.159, the weight of fat is 159*0.159 = 25.281. Round this to the nearest tenth, and we get 25.3 pounds.

An IV of D5W 1000 mL was ordered to infuse over 8 hr at a rate of 42 gtt/min (42 macrogtt/min). Drop
factor: 20 gtt/mL. After 4 hr, you notice that only 400 mL has infused.
Recalculate the rate in gtt/min for the remaining solution
The rate is 50gtt per minutes.
How to calculate the growth rate?From the information, out of the total hours of 8 hours, four hours were used.
The volume will be:
= 1000 - 400
= 600ml
Time = 4 × 60 = 240 minutes
Drop factor = 20
Therefore, the growth rate will be:
= 600/240 × 20
= 50gtt/min

7. Maria, a sales representative for a large consumer goods company, is paid 3% of the total profits earned by her company.
Her company averages 10% profit on sales. If Maria's total income for the year was $60,000, what total sales did her
company realize?
Step-by-step explanation:
60000÷ 10 = 600 and 600 ÷ 3 =20
The total sales realized by the company was $20,000,000.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Let x be the total sales realized by the company.
Maria's pay is 3% of the total profits, which is 3% of 10% of total sales
0.03(0.1x) = 0.003x.
Her total income is given as $60,000, so we have:
0.003x = 60000
Solving for x:
x = 60000/0.003 = 20,000,000
Therefore, the total sales realized by the company was $20,000,000.

Median weekly earnings for women with some college for an associate degree.
1980.......$231
2013.............$657
Using today's dollars, the data in the bar graph can be described by the mathematical model
W = 13n + 231,
Where W represents median weekly earnings n years after 1980.
Does the formula underestimate or overestimate the median weekly earnings in 2013? By how much?
Using the given linear function, the formula underestimates the median weekly earnings in 2013 by $3.
What is the linear function for the estimate?The function that estimates the median weekly earnings n years after 1980 is given by:
W = 13n + 231.
2013 is 2013-1980 = 33 years after 2000, hence the estimate is given by:
W = 13 x 33 + 231 = 660.
Since 657 < 660, the formula underestimates the median weekly earnings in 2013 by $3.

For a certain company, the cost for producing x items is 60x+300 and the revenue for selling x items is 100x−0.5x2 .
The profit that the company makes is how much it takes in (revenue) minus how much it spends (cost). In economic models, one typically assumes that a company wants to maximize its profit, or at least wants to make a profit!
Part a: Set up an expression for the profit from producing and selling x items. We assume that the company sells all of the items that it produces. (Hint: it is a quadratic polynomial.)
Part b: Find two values of x that will create a profit of $50 .
The field below accepts a list of numbers or formulas separated by semicolons (e.g. 2;4;6 or x+1;x−1 ). The order of the list does not matter. To enter a−−√ , type sqrt(a).
The equation for the profit from selling the items is P = 40x-0.5x²-300. The values of x are 10 and 70.
How to solve for the expressionWe have the cost function in this question to be
Cx = 60x+300
Revenue = 100x−0.5x²
A. The revenue function is stated as the revenue - cost
= (100x−0.5x²)-60x+300
We have to open the equation
40x-0.5x²-300
B. when profit is 50 dollars
50 = 40x-0.5x²-300
We have to multiply both sides by 10
500 = 400x - 5x² - 3000
We have to collect like terms and form a quadratic equation
5x² - 400x - 3500 = 0
We have to solve the quadratic equation above using a quadratic calculator.
Hence
x = 10, 70
So the two values that would create a profit of 50 dollars is 10 and 70.

solve which 2 digit number is one more than a square and one less than cube?
The 2-digit number is 26:
26 - 1 = 25 is a square number.
26 + 1 = 27 is a cube number.
How to find the number?
Here we want to find a 2-digit number N, such that:
N + 1 is a cube number.N - 1 is a square number.To do that, we can just create a list of cubic and square numbers of 2 digits, these are:
Square numbers:
4*4 = 16
5*5 = 25
6*6 = 36
etc...
Cube numbers:
3*3*3 = 27
4*4*4 = 64
etc...
Now, we can see that 25 is a square number and 27 is a cube number, then our 2-digit number can be 26.
Because:
26 - 1 = 25 is a square number.
26 + 1 = 27 is a cube number.

a) If two people are chosen, what is the probability that they both prefer Pepsi?
b) If one person is chose, find the probability that they are Female or prefer Coke.
Using it's concept, it is found that the probabilities are given as follows:
a) 0.1431 = 14.31%.
b) 0.7910 = 79.10%.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Item a:
The number of people is:
23 + 44 + 28 + 39 = 134.
The number of people that prefer Pepsi is:
23 + 28 = 51.
Hence, for the two people, the probability is:
p = 51/134 x 50/133 = 0.1431 = 14.31%.
Item b:
There are 23 + 44 = 67 females, and 39 males who prefer Coke, hence the probability is:

A bacteria culture starts with 1000 bacteria and the number doubles every 40 minutes. (a) find a formula for the number of bacteria at time (b) find the number of bacteria after one hour (c) after how many minutes will there be 50000 bacteria?
The formula for the number of bacteria at time t is 1000 x (2^t).
The number of bacteria after one hour is 2828
The number of minutes for there to be 50,000 bacteria is 324 minutes.
What is the number of bacteria after 1 hour?The exponential function that can be used to determine the number of bacteria with the passage of time is:
initial population x (rate of increase)^t

Population after 1 hour : 1000 x 2^(60/40) = 2828
Time when there would be 50,000 bacteria : In(FV / PV) / r
Where:
FV = future bacteria population = 50,000PV = present bacteria population = 1000r = rate of increase = 100%In (50,000 / 1000)
