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.

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

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%.

The missing values in the ratio are 2.5 and 17.5.

What is mean by Ratio?

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,

10 * 7 = y * 4

y = 70/ 4

y = 17.5

Hence, The missing values in the ratio are 2.5 and 17.5.

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.

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.

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.

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

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

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:

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.

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

The radius of the sprinkler is approximately 7 yards.

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:

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

171 = π · r²

r = √(171 / π)

r ≈ 7.378 yd (approx. 7 yd)
