Mr. Vella can build a brick wall in 4 days. His apprentice can build the same wall in 6 days. After working alone for 3 days, Mr. Vella became ill and left the job for his apprentice to complete. How many days did it take the apprentice to finish the wall?

Answers

Answer 1
After working for 3 days, Mr. Vella has finised 3/4 of the work. so for the assistant, 3/4 of 6 is 9/2 which is 4 1/2. So 4 1/2 days of work has been done for the apprentice, so 6 - 4 1/2 = 1 1/2. The apprentice finished the wall in 1 1/2 days. 
Answer 2

Apprentice will take [tex]1\frac{1}{2}[/tex] days  to finish the wall.

What is work?

" Work is defined as when force is applied to move an object in the direction of displacement."

According to the question,

Number of days taken by Vella to build a brick = 4 days

Work done by Vella in 1 day = [tex]\frac{1}{4}[/tex]

Work done  by Vella in 3 days = [tex]\frac{3}{4}[/tex]

Number of days taken by apprentice to build same brick = 6 days

Total days taken by apprentice to complete 3/4 of work =  [tex]\frac{3}{4} of 6[/tex]

                                                     = [tex]\frac{3}{4}[/tex] × 6

                                                     =[tex]\frac{9}{2}[/tex]

                                                     = [tex]4\frac{1}{2}[/tex] days

Number of days apprentice take to finish the wall is = 6 - [tex]4\frac{1}{2}[/tex]

                                                                                       = [tex]1\frac{1}{2}[/tex]

Hence, apprentice will take [tex]1\frac{1}{2}[/tex] days  to finish the wall.

Answers

Kitty Kibbles has a higher unit price of $1.50 / pound
Answer:

The statement which is true about the unit price is:

Kitty Kibbles has a higher unit price of $1.50 /pound.Step-by-step explanation:A 16 -pound bag of Kitty Kibbles is $24.00 .

i.e.

16 pound cost= $ 24

Hence,

cost of 1 pound= $ (24/16)

                         = $ 1.50

i.e. unit price of Kitty Kibbles is: $ 1.50

Also,

An 8 -pound bag of Feline Flavor is $11.20

i.e. cost of 8 pound of Feline Flavor= $ 11.20

cost of 1 pound of Feline Flavor= $ (11.20/8)

                                                    = $ 1.40

Hence,  unit price of Feline Flavor is: $ 1.40

Lindsey has 45ft of metal fencing to form 3 sides of a rectangular garden. A tall wooden fence already in place will serve as the fourth side. What lengths of fencing will produce the largest area?

Answers

To answer this item, we let L be the length and W be the width. The area of the rectangles is calculated through the equation,

           Area = L x W

From the given scenario, we can deduced that,
              L + 2W = 48 

Such that L = 48 - 2W.

Substituting this to the equation for area,
           Area = (48 - 2W)(W)

Simplifying,
            Area = 48W - 2W²

Differentiating and equating to zero,
             dArea = 48 - 4W = 0

The value of W from the equation is 12. Hence,
           L = 48 - 2W = 48 - 2(12) = 24

The dimensions are:
             Length = 24 ft
              Width = 12 ft
Final answer:

To maximize the area of a rectangular garden with one side already fenced, Lindsey should allocate the 45 ft of fencing available to form the remaining three sides in a way that makes the two lengths and the width as equal as possible. While an exact numerical answer depends on additional constraints, the guiding principle is that a more square-like configuration will yield the largest area.

Explanation:

The question asks what lengths of fencing will produce the largest area for a rectangular garden, given that Lindsey has 45 ft of metal fencing and an existing tall wooden fence will serve as one side of the rectangle. To maximize the area enclosed by a given perimeter, which in this case is the length of the fencing available for three sides of the rectangle (since one side is already in place), it is beneficial to review a principle regarding geometric figures and their areas.

It is a well-established mathematical principle that of all rectangles with a given perimeter, the square has the largest area. However, since one side is already provided and Lindsey is forming only three sides of the rectangle, the problem slightly deviates from forming a perfect square. Nonetheless, the principle that more equidistant lengths result in larger areas can guide us to maximize the area Lindsey can enclose.

Lindsey has 45 ft of fencing to create three sides of a rectangle. For simplicity, let's denote the lengths of the two equal sides as L, and the length of the third side (parallel to the existing fence) as W. Since the total length of fencing is 45 ft, the equation we have is 2L + W = 45. To maximize the area (A = L*W), Lindsey should opt for dimensions where L and W are as close as possible to each other within the constraint of the given perimeter (or in this case, the total length of fencing available).

However, without additional constraints (like the length of the existing fence), a definitive numerical answer cannot be provided. The general advice for Lindsey is to distribute the length of the fencing as evenly as possible between the two lengths and the width she needs to create, thereby approximating a square's dimensions which tends to maximize the enclosed area.

What is the slope of a line that is perpendicular to a line whose equation is −2y=3x+7 ?

Enter your answer in the box.

Answers

Answer:

[tex]\frac{2}{3}[/tex] is the Slope of a line that is perpendicular to a given line equation -2y=3x+7

Step-by-step explanation:

We are given here with the equation of the line [tex]-2y=3x+7[/tex] or we can write this equation as [tex]y=\frac{-3}{2}x+\frac{-7}{2}[/tex]

the general equation of the line [tex]y=mx+b[/tex]  where m is the slope and b is the y-intercept.

Compare the given equation with general equation we get,

the value of  slope(m) [tex]=\frac{-3}{2}[/tex]

The slope of line perpendicular to a line is, [tex]m_{perpendicular}=\frac{-1}{m}[/tex]

Since, the slope of the given line is, m=[tex]\frac{-3}{2}[/tex]

then, [tex]m_{perpendicular}=\frac{-1}{\frac{-3}{2} }[/tex][tex]=\frac{2}{3}[/tex]

Therefore, the slope of a line that is perpendicular to a line whose equation is -2y=3x+7 is, [tex]\frac{2}{3}[/tex]

The slope of the line that is perpendicular to a line whose equation is -2y = 3x + 7 is 2/3.

For lines to be perpendicular to each other, the product of there slopes is equals to negative 1. This can be mathematically represented as follows

m₁ × m₂ = -1

where

m₁ and m₂ are slopes of the lines.

Therefore,

let's find the slope of the equation given

-2y = 3x + 7

divide both sides by -2

y = -3/2 x + 7/2

Using the slope equation model,

y = mx + c

where

m = slope

The slope in our equation will be - 3/2.

Using the first formula for perpendicular lines,

m₁ × m₂ = -1

-3/2 m₁= -1

m₁  = -2/-3

m₁ = 2/3

The slope of the line is 2/3

How to solve a multiplication problem with a variable?

Answers

In order to move a number that is multiplied or divided by the variable, you must do the inverse to both sides. That means, if the number is multiplied, you must divide it by both sides. If it's divided, you must multiply it by both side. steps so that you can apply them to more complex problems.

Example Question: 6x + 4 = 22

The goal in this is to get the variable alone and these are the steps how to. What you have to do is subtract 4 from 4 so that you can get 6x alone. But when you subtract 4 from one side, you have to subtract 4 from the other side too which leaves us with 6x = 18. Now, we have to do the opposite of multiplication which is division. So we are going to do 6x divided by 6 and the two sixes cancel each other out. But remember, if you do something to one side you have to do it to the other as well. So we have to do 18/6 which leaves us with the answer.

The sum of three numbers is 50. one number is 10 more than the second number it’s also twice the third find the number

Answers

x + y + z = 50
y  + 10 = x, solving for y, y = x - 10
x = 2z, solving for z, z = x/2
Substituting for y and z,

x + x - 10 + x/2 = 50
(5/2)x - 10 = 50
(5/2)x = 60
x = (2/5) * 60 = 24
y = x - 10 = 24 - 10 = 14
Z = x/2 = 24/2 = 12

Checking:
x + y + z = 50, 24 + 14 + 12 = 50, 50 = 50. Solution meets the initial constraint. 

The three numbers will be 24, 14 and 12 respectively.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is the sum of three numbers is 50 and first number is 10 more than the second number and it is also twice the third.

Assume that the three numbers are [x] , [y] and [z].

Then, we can write -

x + y + z = 50       ..[1]

x = y + 10        ..[2]

x = 2z           ..[3]

Equating Eq [2] and Eq [3], we get -

2z = y + 10

Rearranging the equation above -

y = 2z - 10

Now, for Eq [1], we can write -

2z + z + y = 50

3z + y = 50

3z + 2z - 10 = 50

5z = 60

z = 12

Then, the value of [y] will be -

y = 2 x 12 - 10

y = 24 - 10

y = 14

and

x = 2z = 2 x 12 = 24

Therefore, the three numbers will be 24, 14 and 12 respectively.

The measure of a supplementary angle to one that measures 79° is 101°, since supplementary angles sum up to 180°.

Explanation:

If the measure of an angle is 79°, the measure of a supplementary angle can be found by subtracting this angle from the total degrees in a straight line. In other words, the sum of the measures of supplementary angles is 180°. Therefore, to find the measure of a supplementary angle when one angle measures 79°, we perform the following calculation:

180° - 79° = 101°

So, the measure of the supplementary angle is 101°.
