Answer:

$ 0.83 on one pound

Step-by-step explanation:

Given: Martha spent $2.90 on 3 1\2 pounds of bananas.

To Find: How much did she spend on each pound of bananas

Solution:

Amount spent by martha on bananas = [tex]\$[/tex] [tex]2.90[/tex]

Quantity of bananas bought                = [tex]3\frac{1}{2}[/tex] [tex]\text{pound}[/tex]

                                                              = [tex]\frac{7}{2}[/tex] [tex]\text{pound}[/tex]

Now,

Martha spent [tex]\$[/tex] [tex]2.90[/tex] on = [tex]\frac{7}{2}[/tex] [tex]\text{pound}[/tex] of bananas

therefore,

Amount spent by Martha on one pound of banana= [tex]\frac{\text{quantity of banana bought}}{\text{Amount spent on bananas}}[/tex]

                                                                        = [tex]\frac{2.90}{\frac{7}{2}}[/tex]

                                                                        = [tex]\frac{2.90\times2}{7}[/tex]

                                                                        = [tex]\$[/tex] [tex]0.83[/tex]

Hence amount spent by martha on one pound of banana is [tex]\$[/tex] [tex]0.83[/tex]

Answer:

D

Step-by-step explanation:

Since the constructed line is a perpendicular bisector of the line AB, then

AC = BC ← substitute values

4x + 12 = 2x + 18 ( subtract 2x from both sides )

2x + 12 = 18 ( subtract 12 from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Hence

AB = 2AC = 2(4x + 12) ← substitute x = 3

AB = 2(12 + 12) = 2 × 24 = 48 → D

Simplification of [tex]\frac{\tan 9 x-\tan 5 x}{1+\tan 9 x \tan 5 x}[/tex]  is tan⁡ 4x

Solution:

By using sum-difference formula for tangent,  

Tangent of difference between two angles is written as,

[tex]\tan (x-y)=\frac{\tan x-\tan y}{1+\tan x \tan y}(\text { Equation } 1)[/tex]

By comparing the above equation 1 with [tex]\frac{\tan 9 x-\tan 5 x}{1+\tan 9 x \tan 5 x}[/tex]   ,  

we get x = 9x and y = 5x

By substituting  x =  9x and y = 5x in equation 1,

[tex]\begin{array}{l}{\tan (9 x-5 x)=\frac{\tan 9 x-\tan 5 x}{1+\tan 9 x \tan 5 x}} \\\\ {\tan (4 x)=\frac{\tan 9 x-\tan 5 x}{1+\tan 9 x \tan 5 x}} \\\\ {\text { Therefore, } \frac{\tan 9 x-\tan 5 x}{1+\tan 9 x \tan 5 x}=\tan 4 x}\end{array}[/tex]

Hence by using difference formula for tangent,  [tex]\frac{\tan 9 x-\tan 5 x}{1+\tan 9 x \tan 5 x}[/tex]  is simplified as tan⁡4x

Answer:

A - True

B - False

Step-by-step explanation:

Looking at option A,

Company B had 3.12 subscribers and earned 119. To find each subscriber's value we divide 119 by 3.12

119/3.12 = 38.14

Looking at Option B,

Company A had 2.45 subscribers and earned 108. To find each subscriber's value, we divide 108 by 2.45

108/2.45 = 44.08

Hence, for Option A, each subscriber paid about $40 is correct because it's close to 38.14

For Option B, each subscriber paid about 30 is incorrect since it's way over, 44.08.

Thus,

A - True

B - False

Answer:

If we convert 22,647 inches into miles, we can get 0.357433710227 miles.

The mile, sometimes known as the international mile or the statute mile to differentiate it from other miles, is a British imperial unit and a customary unit of distance in the United States; both are based on the older English unit of length equal to 1,760 yards.

Yards are a measurement that is 36 inches long (or wide) in US units.

We have to convert 22,647 inches into miles.

Since 36 inches = 1 yard,

1 inch = 1/36 yards

i.e. 22,647 inches = 22,647/36 yards = 629.08333 yards.

Since 1,760 yards = 1 mile,

1 yards = 1/1760 miles

i.e. 629.08333 yards = 629.08333/1760 miles = 0.357433710227 miles

Therefore if we convert 22,647 inches into miles, we can get 0.357433710227 miles.

Step-by-step explanation:

f(x)=(3+x)/(x-3)

To evaluate f(a+2), simply replace the x with a+2

f(a+2) = (3 + a+2)/(a+2 - 3)= (a+5)/(a-1)

or

To answer items such as this, we directly substitute the a + 2 to the all the x's in the function:

f(a + 2) = (3 + a + 2) / (a + 2 - 3)

Simplifying the function generated above:

f(a + 2) = (5 + a) / (a - 1)

Step-by-step explanation:

f(x) = 3+x/x-3

Substituting x = a+2, we get

Step-by-step explanation:

Answer:

The faster pipe will take 16 hours to fill the pond alone

Step-by-step explanation:

* Lets explain how to solve the problem

- A sewage treatment plant has two inlet pipes to its settling pond

- One pipe can fill the pond 3 times as fast as the other pipe

∴ The rate of the faster pipe is 3 times the rate of the second pipe

- The rate and the time are inverse proportion because;

 time = job/rate and the job here is constant (fill pool), then

 time × rate = constant

∵ The rate of the faster pipe is 3 times the rate of the second pipe

∴ The time of the second pipe is 3 times the time of the faster pipe

- Assume that the time of the faster pipe is t

∵ The time of the faster pipe is t

∴ The time of the second pipe is 3t

- Together they can fill the pond in 12 hours

∴ [tex]\frac{1}{3t}+\frac{1}{t}=\frac{1}{12}[/tex]

- The L.C.M of 3t and t is 3t

∴ [tex]\frac{1}{3t}+\frac{3}{3t}=\frac{1}{12}[/tex]

∴ [tex]\frac{1+3}{3t}=\frac{1}{12}[/tex]

∴ [tex]\frac{4}{3t}=\frac{1}{12}[/tex]

- By using cross multiplication

∴ 48 = 3t

- Divide both sides by 3

∴ t = 16

∵ t represents the time of the faster pipe

∴ The time of the first pipe is 16  hours

* The faster pipe will take 16 hours to fill the pond alone

Final answer:

The faster pipe will take 6 hours to fill the sewage treatment pond by itself, calculated by setting up and solving a rate problem based on the information provided.

Explanation:

To determine how long it will take for the faster pipe to fill the sewage treatment pond alone, we can set up a rate problem where the pipes are filling the pond at their rates and a combined rate.

Let's define the rate of the slower pipe as 1/x ponds per hour (where x is the number of hours it takes the slower pipe alone to fill the pond). This means that the faster pipe works at a rate of 3/x (since it's three times as fast).

Combined, their rate is 1/12 ponds per hour (because together they fill the pond in 12 hours). Our equation will now look like this: 1/x + 3/x = 1/12.

Solving this equation, we find that x, the time it takes for the slower pipe to fill the pond alone, is 18 hours. Therefore, the faster pipe, being three times as fast, will take 18 hours divided by 3, which equals 6 hours to fill the pond alone.

Let

d -----> the distance in meters

t ----> the time in seconds

Looking at the graph we have the point (3,5)

That means ----> For t=3 sec, d=5 m

General steps have been given to approach solving such problems, with a note that a specific solution requires the complete inequality. The student should provide the full inequality for a precise solution.

The student is asking for help with solving an inequality problem. Without a complete and clear inequality provided, we are unable to give a full step-by-step solution. However, I can provide a general approach to solving linear inequalities:

If the student provides the full inequality, using these steps will lead to the solution, where you would then graph the solution set on a number line and use either parenthesis or brackets to denote whether endpoints are included (for 'greater/less than or equal to') or excluded (for 'greater/less than').
