Answer:
67 = 3n + 14
Step-by-step explanation:
So we know its going to equal 67, and 3 times a number is the same as 3n more than is to show addition. That means you are adding 14 to 3n.
That's why it would be,
14 + 3n = 67
Hope that helps and have a great day!

Use appropriate algebra and Theorem 7.2.1 to find the given inverse Laplace transform. (Write your answer as a function of t.) ℒ−1 s (s − 4)(s − 5)(s − 20)
Answer:
[tex]L^{-1} \begin {pmatrix} \dfrac{s}{((s-20)(s-5)(s-4)} \end {pmatrix}= \dfrac{e^{4t}}{12}\begin {pmatrix}e^{16t} - 4e^t+3 \end {pmatrix}[/tex]
Step-by-step explanation:
From the given information the first step to carry out is to find the partial fraction of the given equation; i.e.
[tex]\dfrac{s}{(s-4)(s-5)(s-20)}= \dfrac{A}{s-4}+\dfrac{B}{s-5}+\dfrac{C}{s-20}[/tex]
After finding the partial fraction; we get:
[tex]s= s^2(A+B+C)+s(-2A-24B-25C)+20A+80B+100C[/tex]
By solving this; we get:
[tex]A =\dfrac{1}{12}\ ; \ B = -\dfrac{1}{3} \ ; \ C= \dfrac{1}{4}[/tex]
Thus; the above equation can be re-written as:
[tex]\dfrac{s}{(s-20)(s-5)(s-4)}= \dfrac{\dfrac{1}{12}}{s-20}+\dfrac{-\dfrac{1}{3} }{s-5}+\dfrac{\dfrac{1}{4}}{s-4}[/tex]
Finally as a function of t ;
[tex]L^{-1} \begin {pmatrix} \dfrac{s}{((s-20)(s-5)(s-4)} \end {pmatrix}= \dfrac{e^{4t}}{12}\begin {pmatrix}e^{16t} - 4e^t+3 \end {pmatrix}[/tex]

The salaries of Kofi and Ama are in the ratio 3:5. If the salary of each is raised by ¢4000, the new ratio becomes 40:57. what is Ama's salary
Answer:
34000
Step-by-step explanation:
New Ratio = 40/57
Gap between numerator & denominator = 17
Original Ratio = 2/3
Gap between numerator & denominator = 1
=> Original Ratio can be restated as 34/51 to make gap of both ratios same.
Difference between two numerators OR denominators = 40 - 34 = 6 or 57 - 51 = 6
If gap is 6, sumit’s original salary = 51
If gap = 4000, sumit’s original salary is :
51/6 x 4000 = 34000
The salary of Amma is given as ¢11724.10.
What is the application ratio and proportion?A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.
Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.
The ratio of the salaries of Kofi and Ama is given as 3 : 5.
After adding 4000 to each ratio the new ratio becomes as 40 : 57.
Suppose the present salaries of Kofi and Ama be 3x and 5x respectively.
Then, as per the question following equation can be written as,
(3x + 4000)/(5x + 4000) = 40/57
=> 57(3x + 4000) = 40(5x + 4000)
=> 200x - 171x = 68000
=> 29x = 68000
=> x = 68000/29
= 2344.82
The Amma's salary is given by,
5x = 5 × 2344.82
= 11724.10
Hence, Amma's present salary is given as ¢11724.10.

Answer:
No, it is not a relation function
Step-by-step explanation:
Answer:
No, it is not a function

A distribution is positively skewed. Which is the most probable order for the three measures of central tendency
Answer:
The answer is mode, median, mean.
Step-by-step explanation:
From the smallest to the largest we have the mode, median, mean. If a distribution is positively skewed it means that it is right skewed. It tells us that the right tail of this distribution has longer length compared to the left tail. The average, mean would be moved slightly to the left, the mode occurs at the top while the median is in the middle.

You are conducting an experiment to evaluate how the number of hours spent exercising each week affects blood pressure. What is the independent variable in this experiment
Answer:
The question is incomplete, below is the complete question
You are conducting an experiment to evaluate how the number of hours spent exercising each week affects blood pressure. What is the independent variable in this experiment?
The intensity of the exercise.
The amount of exercise each week.
Blood Pressure
The type of exercise.
Answer:
The amount of exercise each week.
Step-by-step explanation:
The two major kinds of variables in a scientific experiment are the independent and dependent variables.
The independent variable is the variable whose values are completely under the complete manipulation of the experimenter. The experimenter decides what value to assign to the variables in this category and the effect of the manipulation of the independent variable determines the outcome variable. In this example, the amount of exercise each week, which is determined by the number of hours exercised each week is subject to the experimenter, hence it is the independent variable
The dependent or outcome variable is the variable whose values depend on the effect of the manipulation of the independent variable. This variable is not directly subject to the manipulation of the experimenter. In this example, the blood pressure gotten after the exercise is the outcome variable.
The variables in an experiment can be dependent or independent
The independent variable in the experiment is: the amount of exercise each week.
From the question, the parameters are:
Exercise intensity Amount of exercise each week. Blood Pressure Type of exercise.
For a variable to be considered as the independent variable, then the variable is not influenced by other variables or parameters.
Within the scope of this question, the independent variable is the weekly amount of exercise

an 8 inch wide photo has been reduced to a 5 inch wide by 7 inch tall photo. How tall was the original photo?
Answer:
It was 10inches tall
Step-by-step explanation:
If the width was 8 inches tall but then was reduced to 5 inches tall that means it was reduced by 3 inches, so we just do the same thing with the height. If it is 7inches tall after it was reduced then just add 3 inches back to it which means it was 10 inches tall...Ik its kinda confusing but its correct
