Susan is going to ship some gifts to family members, and she is considering two shipping
companies. The first shipping company charges a fee of $20 to ship a medium box, plus an
additional $1 per pound. A second shipping company charges $5 for the same size of box,
plus an additional $4 per pound. At a certain weight, the two shipping methods will cost tre
same amount. How much will it cost? What is that weight?
The two shipping methods both cost $
Submit
at a weight of
pounds.

Answers

Answer 1

The first company shipping charge is 5 $

the second company shipping charge is 2 $

let the size of the box be 'x'

Given the first company charged as below

20$ for medium-sized and an extra 1$ for one pound

=  20x + 1

The second company charged as below

$5 for the same size of the box, plus an additional $4 per pound

= 5x + 4

The price of the two shipping options will be same.

20x + 1 = 5x + 4

20x - 5x = 4- 1

15x = 3

x= 3 / 15

x = 1/5

x = 0.2

∴ 20x+1 = 20 * 0.2 +1 = 5

   5x + 4 = 5 * 0.2 + 1 = 2

Therefore, The first company's shipping fee is $5, whereas the second company's fee is $2.

Douglas Noel went to Home Depot and bought thirteen doors at $43.44 each and six bags of fertilizer at $8.71 per bag.

Round your answers to 2 decimal places.

What was the total cost to Douglas?


If Douglas had $660 in his pocket, what does he have left to spend?

Answers

The total cost  is  $616.98.

The amount he has left to spend is  $43.02.

What is the total cost?

The total cost to Douglas is the sum of the total cost of the thirteen doors and the sum of the six bags of fertilizers

The total cost of the thirteen doors = (cost of one door x total number of doors that would be bought)

$43.44 x 13 = $564.72

The total cost of six bags of fertilizers = (cost of one bag x total number of bags)

$8.71 X 6 = $52.26

Total cost = $564.72 +  $52.26 = $616.98

Amount he has left to spend = $660 - $616.98 = $43.02

What are the domain and range of the function f(x) = x^2 + 5x + 4/ x+4

Answers

This is just a linear equation, then the domain is the set of all real numbers and the range is the set of all real numbers.

How to find the domain and range of the given function?

Here we have the function:

f(x) = (x^2 + 5x + 4)/(x + 4)

The numerator can be rewritten if we find the zeros:

x = (-5 ± √( 5^2 - 4*1*4))/(2*1)

x = (-5 ± 3)/2

Then the zeros are:

x = (-5 - 3)/2 = - 4

x = (-5 + 3)/2 = -1

So the numerator can be rewritten to (x + 4)*(x + 1)

And the function is rewritten to:

f(x) = (x^2 + 5x + 4)/(x + 4) = (x + 4)*(x + 1)/(x + 4) = (x + 1)

This is just a linear equation, then the domain is the set of all real numbers and the range is the set of all real numbers.

A 17 foot ladder is leaning on a wall. the bottom of the ladder on the ground is at a distance of 3 feet from the base of the wall.


What is the distance, in feet, between the griund and the top of the ladder? round your answer to the nearest tenth

Answers

The distance in feet between the ground and the top of the ladder  is 16.7 feet.

Let the distance in feet between the ground and the top of the ladder be x.

According to the given question.

Length of the ladder = 17 foot

The distance of the ladder from the base of the wall is 3 feet.

From the given data we can say that we have a right angle triangle in which the hypotenuse is the length of the ladder, base is the distance between the ladder and wall. And the distance between ground and ladder is our perpendicular.

Now according to the Pythagoras theorem,the sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c).

Therefore,

17^2 = 3^2 + x^2

⇒ 289 = 9 + x^2

⇒ 280 = x^2

⇒ x = 16.7 feet

Hence, the distance in feet between the ground and the top of the ladder  is 16.7 feet.

If the clerk put 108 doughnuts in front of the store, how many doughnuts were there in all at the beginning of the day on Tuesday.

Answers

Using proportions, it is found that 240 doughnuts were there in all at the beginning of the day on Tuesday.

What is the missing information?

The percentages are missing and are given in the graph at the end of the answer.

What is a proportion?

A proportion is a fraction of a total amount, and equations can be built to find the desired measures using the unit rates and operations such as multiplication and division.

One example of application of proportions is for percentage problems, as the decimal equivalent of the percentages are used to find either the equivalent amount or the total amount, by multiplication operations.

The percentages of doughnuts displayed are given as follows:

Cream filled: 20%.Powdered sugar: 25%.

Hence 45% of the total amount is equivalent to 108 doughnuts, hence:

0.45n = 108.

n = 108/0.45

n = 240.

Which is the number of doughnuts that were there in all at the beginning of the day on Tuesday.

Overall, the river festival made £12 858.56. The organisers spent £6429.28 running the festival. How much was the profit, as a percentage of the total money made?

Answers

Step-by-step explanation:

it made £12,858.56.

the costs were £6,429.28

so, the profit was

12,858.56 - 6,429.28 = £6,429.28

since cost and profit are equal, that means they are both exactly half of the total income.

and half means 50%.

formally, to do the full % calculation :

100% = 12,858.56

1% = 100%/100 = 12,858.56/100 = 128.5856

how many % are 6,429.28 ?

as many % as times that 1% fits into 6,429.28 :

6,429.28 / 128.5856 = 50

so, it is 50%.

Answer: 121.176

Step-by-step explanation:

First, multiply out the decimal points. To get 408 from 4.08, multiply by a hundred. Likewise, with 29.7, multiply it by 10.

Then, do long multiplication with 408 and 297 (you get 121176 from that).

Finally, use your answer from the long multiplication and divide it by how many times you multiplied your original numbers. So, you have to divide by 100, and then also divide by 10.

From that, you get 121.176

What is a fraction and division problem?Any number of equal parts is represented by a fraction, which also represents a portion of a whole.

The quantity of "people" among whom the number is divided is referred to as the divisor. The answer is the quotient.

As seen by the definition of fraction, in terms of division problem, it involves only the the dividend and the divisor and not the quotient.

Hence, the two cannot be used inter-changeably, i.e., a fraction is not a division problem and vice versa.

A Ratio is a comparison of two or more numbers that indicates their sizes in relation to each other.

Now, The missing values are find as;

Ratio of Pounds to the weeks are;

In first column,

Pounds : Weeks = 10 : 4

In second column,

Pounds : Weeks = x : 1

In third column,

Pounds : Weeks = y : 7

Since, All ratio are equal.

Hence,

10 : 4 = x : 1

It can be written as,

10/4 = x / 1

After cross multiplication we get;

x = 10/4

x = 2.5

And,

10 : 4 = y : 7

It can be written as,

10/4 = y/7

After cross multiplication we get,

Westside Energy charges its electric customers a base rate of $8.00 per month, plus 12¢ per kilowatt-hour (kWh) for the first 300 kWh used and 4¢ per kWh for all usage over 300 kWh. Suppose a customer uses x kWh of electricity in one month. Express the monthly cost E as a piecewise defined function of x. (Assume E is measured in dollars.)

Answers

The linear function that gives the monthly cost E for x > 300 is given by:

E(x) = 44 + 0.04x.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

When x > 300, we have that:

The base rate of $8.00 was paid.The 12 cents for each kWh up to 300 was paid.

Hence the intercept is given by:

b = 8 + 0.12 x 300 = 44.

The slope is the cost per kWh of 4 cents, hence the function is:

E(x) = 44 + 0.04x.

The radius is approximately ___ yd.

Answers

The radius of the sprinkler is approximately 7 yards.

How long is the arm of the sprinkler?

In this situation we find the case of a sprinkler that rotates until a complete revolution is done, that is, the area of complete circle is covered due to the rotation. That area can be found by using this formula:

A = (θ / 360) · π · r²

Where:

A - Area of rotation, in square yards.θ - Angle of rotation, in degrees.r - Radius of the sprinkler, in yards.

If we know that A = 171 yd² and θ = 360°, then the radius is approximately:

171 = π · r²
