Name the operation the should be done first in this expression: 10 - (3 + 4)

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.

Answer:

6 centimeter is the length of one edge of the boxStep-by-step explanation:

Given  : The volume of a box of earrings is 216 cubic centimeters.

To find : What is the length of one edge of the box.

Solution : We have given

Volume of a cubic box = 216 cubic centimeter .

Volume of cube = (side)³ .

(side)³  = 216 cubic centimeter .

On taking cube root both sides.

side = [tex]\sqrt[3]{216}[/tex].

Side =  [tex]\sqrt[3]{6*6*6}[/tex].

Side=  6 centimeter .

Therefore, 6 centimeter is the length of one edge of the box.

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

Answer:

y ≤  11x + 17

Step-by-step explanation:

Slope - Intercept form looks like:

y = mx + b, where m is the slope of the line and b is the y-intercept

so, for

11x - y ≥ -17   ( Rearrange, move x-term to other side)

- y ≥ -17 - 11x

- y ≥ - (17 +  11x)     (multiply both sides by -1, remember to flip the inequality)

y ≤ 17 +  11x

y ≤  11x + 17  (answer)

Step-by-step explanation:

The final elevation of a fish starts at -9 meters and changes -11 meters is -20 meters.

Integers include all whole numbers and negative numbers. This means if we include negative numbers along with whole numbers, we form a set of integers.

Given that, a fish starts at -9 meters and changes -11 meters.

The fish starts at -9 meter than swims down another 11 meters which results in being -20 meters because it is below sea level.

Therefore, the final elevation of a fish starts at -9 meters and changes -11 meters is -20 meters.

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]

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]

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.

Your Answer Is C. 20%

Answer: 20%

Step-by-step explanation:

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

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)
