Answer:
b ≈ 13.80 in
Step-by-step explanation:
Since the triangle is right use the tangent ratio to solve for b
tan17.71° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{AC}{43.21}[/tex]
Multiply both sides by 43.21
43.21 × tan17.71° = AC, hence
AC = b ≈ 13.80 ( to 2 dec. places )

What is the median of this list of numbers? 5, 10, 13, 7,5
Answers
Median: The middle number when all the numbers are listed in order.
To find the median of the data set shown here, we can first start by putting all the numbers in order from least to greatest.
Least to greatest - 5, 5, 7, 10, 13
Next, we locate the number that is exactly in the middle and if there is no number exactly in the middle, we find the two numbers and find halfway point between them.
The number that is exactly in the middle of the data set is 7 so our median is 7.

The total cost after tax to repair Deborah’s computer is represented by 0.07(4 0h) + 4 0h, where h represents the number of hours it takes to repair Deborah’s computer. What part of the expression represents the amount of tax Deborah has to pay? Explain
Answers
Answer:
depending on the national/ regional legal provisions in favour of the tax contributor where either the work is provided/ the computer was aquired/ placed, repaired/ the repair company has declared fiscal residency the cost ( in hours) could be determined by 0.07 ( 40h)
Final answer:
The expression 0.07(40h) in the equation represents the amount of tax Deborah has to pay. 0.07 stands for the 7% tax rate applied to the cost of repair, which is denoted by 40h.
Explanation:
The student has asked to identify the part of the expression in 0.07(4 0h) + 4 0h, which represents the tax Deborah has to pay for her computer repairs, where h represents the number of hours it takes to repair the computer. In this expression, the tax component is given by 0.07(40h).
The 0.07 represents the 7% tax rate on the cost of repair. The cost of repair, before tax, is represented by the term 40h. When you multiply 40h by 0.07, you are calculating 7% of the repair cost which equates to the tax amount.

Find three consecutive integers whose sum is 441
Answers
Answer:
146, 147 and 148
Step-by-step explanation:
Let the three integers be x, x+1, and x+2.
(they are consecutive)
Now, we are given that their sum is 441.
So,
(x) + (x+1) + (x+2) = 441
3x + 3 = 441
3x = 438
x = 438/3
x = 146
Thus, the integers are:
x = 146
x+1 = 147
x+2 = 148

The product of twice a number and six is the same as the difference of eleven times the number and 6/5 . Find the number
Answers
Answer:
-6/5
Step-by-step explanation:
solution;
let,the number be x,
product of twice of x and six = the difference
difference of eleven times x and 6/5
or, (2x×6)=(11×x)-(6/5)
or, 12x = 11x - 6/5
or, 12x - 11x = -6/5
therefore,x =-6/5
Therefore, the number required is (-6/5) whose product of twice a number and six is the same as the difference of eleven times the number and 6/5 .

John and his three brothers share a cell phone plan. The cell phone company charges a flat rate of $90 per month, which the four brothers share equally. In addition, the cell phone company charges 25 cents per megabyte of data downloaded. Each brother pays for his own downloaded data.
John's share of the current cell phone bill is $147.50.
Which equation determines how many megabytes of data John downloaded?
Answers
Answer:
(147.50 - 22.5)/.25
Step-by-step explanation:
First subtract his portion of the $90. Which is $22.5, when subtracted from 147.5 you get $125. Now divide $125 by .25 cents and you get the amount of megabytes he downloaded.
Answer: 22.5+0.25x=147.50
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Flat rate: $90, (share equally among the four brothers means 90/4 =$$22.5 each) Cost per megabyte: $0.25 John's share: $147.50So, the equation is
22.5+0.25x=147.50

The problem:
If h(x)=-7x and h(x)=63, the what is the value of x?
Step-by-step explanation:
h(x)=-7x
You are asked to find x such that h(x)=63.
So you are solving:
h(x)=63 for x:
-7x=63
Divide both sides by -7:
x=63/-7
Simplify:
x=-9
Let's check:
h(x)=-7x
h(-9)=-7(-9)
h(-9)=63
So -9 is the answer.
The value of x in the equation y = 9 + 3x for a given y value can be found by rearranging the equation to x = (y - 9) / 3, and substituting the desired y value.
Explanation:The subject of this question is determining the value of x in the equation y = 9 + 3x. In this equation, the b term is 9 and the m term is 3, representing the y-intercept and the slope respectively. To find the value of 'x' that gives a specific 'y' value, one must rearrange the equation to solve for 'x': x = (y - 9) / 3. For example, if we wanted the y value to be 15, we would substitute into the equation and find that x = (15 - 9) / 3 = 2

Step-by-step explanation:
v= 1/3 bh

3v = bh
dividid by b : h = 3v/b
To solve for h in the equation v = (1/3)bh, you need to isolate h on one side. Multiply both sides by 3 to eliminate the fraction, then divide both sides by b to solve for h.
Explanation:To solve the equation v = (1/3)bh for h, we need to isolate h on one side of the equation.
First, we can multiply both sides of the equation by 3 to get rid of the fraction: 3v = bh.
Next, to solve for h, we divide both sides of the equation by b. This gives us the final answer: h = 3v / b.

How do I identify the rate of change on a linear function?

Answer:
Slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run.
Another way to state this is that the average rate of change remains the same for the entire domain of a linear function.

Teresa’s age is 5 years more than twice Ben’s age. If Ben is x years old, the expression _____ gives the sum of Ben’s and Teresa’s ages. If Ben is 7 years old, the sum of Ben’s and Teresa’s ages is _____ years.
Answers
Using a system of equations, it is found that:
If Ben is x years old, the expression 3x + 5 gives the sum of Ben’s and Teresa’s ages. If Ben is 7 years old, the sum of Ben’s and Teresa’s ages is 26 years.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given by:
Variable x: Ben's age.Variable y: Teresa's age.Teresa’s age is 5 years more than twice Ben’s age, hence:
y = 2x + 5
The sum of their ages is:
x + y = x + 2x + 5 = 3x + 5.
Ben is 7 years old, hence the sum is given by:
3(7) + 5 = 26.
Then:
If Ben is x years old, the expression 3x + 5 gives the sum of Ben’s and Teresa’s ages. If Ben is 7 years old, the sum of Ben’s and Teresa’s ages is 26 years.

The sum of Ben's and Teresa's ages is represented by the expression 3x + 5, and when Ben is 7 years old, their total age is 26 years.
Explanation:The expression to represent the sum of Ben's age and Teresa's age, given that Ben is x years old and Teresa's age is 5 years more than twice Ben's age, is 2x + 5 + x. This can also be simplified to 3x + 5.
When Ben is 7 years old, we plug in the value 7 for x in the simplified expression to calculate the sum of their ages: 3(7) + 5, which equals 21 + 5.
Therefore, the sum of Ben's and Teresa's ages when Ben is 7 years old is 26 years.
