Answer:
See below.
Step-by-step explanation:
The equation is already solved for p.
p = 75 + 45h
Final answer:
To solve for the fluid density 'p', use the hydrostatic pressure formula P = pgh. By rearranging the formula to p = P / (gh) and inputting the known values for P (atmospheric pressure) and h (height of the water column), the density can be calculated.
Explanation:
To solve for density 'p' when given the equation P = 75 + 45h, where P represents atmospheric pressure and h is the height of a column of fluid, we need to incorporate the concept of hydrostatic pressure. The formula for hydrostatic pressure is P = pgh, where 'p' is the fluid density, 'g' is the acceleration due to gravity, and 'h' is the height of the fluid column. If we know the value of 'P' and the value of 'h', we can isolate 'p' by rearranging the equation to p = P / (gh). This calculation assumes that 'g', the acceleration due to gravity, is a known constant.
Let's assume 'P' is given as 1.00 atm (standard atmospheric pressure) for a water column which is the fluid we're working with. The density 'p' of water that creates this pressure can be calculated by inserting the known values into the expression for 'h'. For instance, if 'h' is 10 meters, the equation would be p = 1.00 atm / (9.81 m/s² × 10 m). To get 'p' in appropriate units, we would convert atm to pascals, and the result will provide the density in kg/m³.
A self-serve frozen yogurt store made these graphs to study the data collected about its customers' purchases. Which statement is true?
(Graph Shoen in picture above)
Data collection is the process of gathering and measuring information on variables of interest. strawberry yoghurt makes up less than 1/3 of their sales
What is data collection?
Data collection is the process of gathering and measuring information on variables of interest, in an established systematic fashion that enables one to answer stated research questions, test hypotheses, and evaluate outcomes.
The data collection component of research is common to all fields of study including physical and social sciences, humanities, business, etc. While methods vary by discipline, the emphasis on ensuring accurate and honest collection remains the same.
In the first graph, the strawberry yogurt is a little larger than 1/4. Second, the yogurt increases instead of decreases n the first six months. And third, the store actually sold a little less than 3,000 yogurts in November than in August.

Pam bought several cartons of Giggle Fruit Drinks to sell during the track meet. She paid 50 cents per carton. She sold all but 15 of the cartons for $1 each. At the end of the day, her profit was $22.50. How many cartons of Giggle did she buy?
Good evening
Answer:
75Step-by-step
let c be the total number of cartoons
Cost of purchase = 50c
total sale price = 100(c-15)
profit = total sale price - cost of purchase
= 100(c-15) - 50c = 2250 cents
Then (100c-50c) - 1500 = 2250
then 50c = 3750
Then c = 3750/50 = 75

Evaluate when x=-12
Can someone help me I don’t understand this :(
Answer:
2102
Step-by-step explanation:
Evaluate -x³+3x²+5x+1 when x = -12
simply substitue x = -12 into the equation
-x³+3x²+5x+1 when x = -12
= - (-12)³ + 3(-12)² + 5(-12)+1
= -(-1728) + 3(144) - 60 + 1
= 1728 + 432 - 60 +1
= 2102
To evaluate the polynomial -x^3 + 3x^2 + 5x + 1 for x = -12, we substitute -12 for x and simplify, resulting in a final value of 2101.
The student is asking to evaluate the polynomial -x^3 + 3x^2 + 5x + 1 when x = -12. To solve this, we substitute -12 for x in the polynomial and simplify:
Substitute x with -12: -(-12)^3 + 3(-12)^2 + 5(-12) + 1Simplify the equation: -( -12 x -12 x -12) + 3( -12 x -12) + 5( -12) + 1Calculate the powers: -(-1728) + 3(144) - 60 + 1Multiply and add: 1728 + 432 - 60 + 1Combine like terms: 1728 + 432 - 60 + 1 = 2101Therefore, when x = -12, the polynomial evaluates to 2101.

A magazine as states that 4 out of 7 dentists prefer flash toothpaste.If 1400 dentists were surveyed, how many dentists recommended Flash toothpaste
800 dentists recommended Flash toothpaste
Solution:
Given that, magazine as states that 4 out of 7 dentists prefer flash toothpaste
1400 dentists were surveyed
To find: Number of dentists recommended falsh toothpaste
Let "x" be the number of dentists recommended falsh toothpaste
Then, we can say,
4 out of 7 equals x out of 1400
[tex]\rightarrow \frac{4}{7} = x \times 1400\\\\\rightarrow x = \frac{4}{7} \times 1400\\\\\rightarrow x = 800[/tex]

What is the range of f(x) = 3/4x -4
{y | y > –4}
{y \ y > 3/4}
{y | y < – 4}
{y | y < 3/4}
Answer:
The range is the resulting y-values we get after substituting all the possible x-values.
For the given function : [tex]f(x) = \frac{3}{4x} -4[/tex]
See the attached figure.
The zeros of the denominator at x = 0
The domain is: (-∞,0)∪(0,∞)
The range of the function is the domain of the inverse function of f(x)
y = 3/(4x) - 4
y + 4 = 3/(4x)
4x = 3/(y+4)
[tex]x=\frac{3}{4(y+4)}[/tex]
The zeros of the inverse function:
4(y+4) = 0
y + 4 = 0
y = -4
∴ The range is (-∞,-4)∪(-4,∞)
So, the answer is {y | y > –4} ∪ {y | y < – 4}
=========================================
Note: If the given function is : [tex]f(x) = \frac{3}{4} x-4[/tex]
It will be first degree polynomial function.
Both of the domain and the range = all real numbers R

Cruz is training to compete in a triathlon. He left his house at 6:00 and ran until 7:30. Then he rode his bike until 9:45. He covered a total distance of 51 miles. His speed when biking was 1.6 times his speed when running. Find Cruz’s biking and running speeds.
The speed in running is 10 mph and speed in biking is 16 mph
Solution:
Given that, Cruz is training to compete in a triathlon
He left his house at 6:00 and ran until 7:30
Time taken for running = 1.5 hours
Then he rode his bike until 9:45
7: 30 to 9: 45 is biking time
Time taken for biking = 2.25 hours
He covered a total distance of 51 miles
Total distance = 51 miles
Let "x" be the speed in running
His speed when biking was 1.6 times his speed when running
Speed in biking = 1.6x
Total distance = distance in running + distance in biking
The distance is given by formula:
[tex]distance = speed \times time[/tex]
Therefore,
[tex]Total\ Distance = x \times 1.5 + 1.6x \times 2.25\\\\51 = 1.5x + 3.6x\\\\5.1x = 51\\\\x = 10[/tex]
Thus speed in running is 10 miles per hour
Speed in biking = 1.6x = 1.6(10) = 16
Thus speed in running is 10 mph and speed in biking is 16 mph

solve the inequality. (x-3)(x-4)/(x-5)(x+6)^2>0
Answer:
C
Step-by-step explanation:
Answer:
C.
Step-by-step explanation:
Consider the numerator;
When (x - 3)(x - 4) = 0
x = 3 or x = 4.
When x > 3 and < 4 (x - 3)(x- 4) will be negative and the denominator (x - 5(x + 6)^2 will be negative so the function will be positive.
So 3 < x < 4 is a part of the answer.
When x > 5 the denominator will be positive and so will be the numerator.
So x > 5 also is a solution.
When x < 3 the numerator will be positive and the denominator will be negative so the function will be negative.

f(x) = x − 8, g(x) = x2 Find (f + g)(x)
[tex](f+g)(x) \text{ is equal to } x^2+x-8[/tex]
Solution:
Given that the functions are:
[tex]f(x) = x-8\\\\g(x)=x^2[/tex]
We have to find the value of (f + g)(x)
By operations on functions, we know that,
(f + g)(x) = f (x) + g(x)
Thus (f + g)(x) can be found by adding both the given functions
[tex](f + g)(x) = f (x) + g(x)\\\\(f + g)(x) = x - 8 + x^2\\\\(f + g)(x) = x^2+x-8[/tex]
Thus (f + g)(x) is equal to [tex]x^2+x-8[/tex]

The maximum number of pages for which the time to print at Jerry's Print Shop is less than at Joe's Print Shop is 14.
Explanation:This question deals with comparing two linear equations [tex]t1 = 45 + 5p[/tex] for Joe's Print Shop and t2 = 30 + 6p for Jerry's Print Shop. To determine the maximum number of pages (p) where Jerry's shop is quicker than Joe's, we need to find the value of p where t2 < t1.

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle:
A(-7,-5), B(-7, 6), C(-4,6), and D(-4,-5).
Given these coordinates, what is the length of side CD of this rectangle?
The length of side CD is 11.
To find the length of side CD, we can use the distance formula, which is as follows:
distance = √((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
In this case, the coordinates of the two points are (-4, -5) and (-4, 6). Substituting these coordinates into the distance formula, we get:
distance = √(((-4) - (-4))^2 + ((6) - (-5))^2)
distance = √(0^2 + 11^2)
distance = √121
distance = 11
Therefore, the length of side CD is 11.

18 is what percentage of 25
Answer:
Step-by-step explanation:
72%
Answer: 72%
Step by Step Explanation:
1. We assume, that the number 25 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 25, so we can write it down as 100%=25.
4. We know, that x% equals 18 of the output value, so we can write it down as x%=18.
5. Now we have two simple equations:
1) 100%=25
2) x%=18
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=25/18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 18 is what percent of 25
100%/x%=25/18
(100/x)*x=(25/18)*x - we multiply both sides of the equation by x
100=1.38888888889*x - we divide both sides of the equation by (1.38888888889) to get x
100/1.38888888889=x
72=x
x=72
now we have:
