Step-by-step explanation:

The gas tank holds 60 quarts.

What is quarts?

The quart is an English volume unit equivalent to one-quarter gallon. There are now three types of quarts in use: the liquid quart and dry quart of the US customary system, as well as the imperial quart of the British imperial system. All of them are essentially equivalent to one liter. It is split into two pints or four cups (in the United States). The exact size of the quart has historically fluctuated with the varying values of gallons over time and in relation to different commodities.

1 US gallon = 4 US quarts

so, 15 US gallons = 15 x 4 = 60 quarts

Given the length of the perpendicular height and base length, the hypotenuse of the right triangle is 2√74 ft.

Hence option a)2√74 ft is the correct answer.

The Pythagoras theorem can be expressed as;

c = √( a² + b² )

Where c is hypotenuse, a and b are the other two sides of the right triangle.

Given the data in the image;

Plug the given values into the above equation and solve for the hypotenuse 'c'.

c = √( a² + b² )

c = √( (14)² + (10)² )

c = √( 196 + 100 )

c = √( 296 )

296 can be written as 4 × 74, and 4 can further be written as 2²

Hence

c = √( 2² × 74 )

c = 2√74 ft

Given the length of the perpendicular height and base length, the hypotenuse of the right triangle is 2√74 ft.

Hence option a)2√74 ft is the correct answer.

Values of x and y in the given equations by elimination method are 5 and 7 respectively. that is, x=5 and y=7.

In the elimination method, the aim is to entirely remove one of the unknown variable which would eventually make it easier to calculate be other unknown. However, it is important to note that this method is most effective when neither of the coefficients is equal to 1. The coefficient of either of the two variables will be made the same in both equations and by subtracting one from the other, it would be eliminated. It is a non-graphical methods of solving simultaneous linear equations.

consider the equations as (1) and (2),

-9x+10y=25..........................(1)

   7x-4y=7............................(2)

Now, multiply equation (1) by 4 and equation (2) by 10

Let the equations we get now be (3) and (4),

-36+40y=100......................(3)

70x-40y=70........................(4)

We can see that the coefficient of y in both equations is same that is 40

Now, add equation (3) and (4)

-36+40y+70x-40y=100+70                ( y terms cancel out)

By evaluating we get,

-34x=170

x=-170/34

x=5

To find the value of y, substitute value of x in equation (2)

7x-4y=7

7*5-4y=7

35-4y=7

35-7=4y

28=4y

y=28/4

y=7

Therefore, we can conclude that the values of x and y in the given equations -9x+10y=25 and 7x-4y=7 by elimination method are 5 and 7 respectively. that is, x=5 and y=7.

The value of the width is greater than the 21 if we want a perimeter greater than the 72 feet. Then if we let value of y is 25 then length is 19 and width is 25.

According to the statement

We have to find that the length and the width.

So, For this purpose, we know that the

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon

From the given information:

The length of the plot to be 6 feet less than the width.

Then

The given perimeter = greater than 72 feet.

We know that the perimeter of rectangle is

P = 2(length + breadth)

And

P < 2(length + breadth)

here p = 72, let length = y - 6 and width = y

Then

72 < 2(length + breadth)

72 < 2(y - 6 + y)

72 < 2(2y - 6)

72 < 4y - 12

84 < 4y

y >  21.

Then let the value of y is 25 then

length = 25 - 6 and width = 25

length = 19 and width = 25.

The solution of the geometric system is (x, AB, BC, AC) = (10, 14, 19, 33).

In accordance with geometry, three points are collinear if and only if these points lie on the same line. Then, the geometric system is represented by the following model:

AC = AB + BC

If we know that AB = x + 4, BC = 2 · x - 1 and AC = 4 · x - 7, then the value of x and the lengths of the line segments are, respectively:

4 · x - 7 = (x + 4) + (2 · x - 1)

4 · x - 7 = 3 · x + 3

x = 10

AB = 10 + 4

AB = 14

BC = 2 · 10 - 1

BC = 20 - 1

BC = 19

AC = 4 · 10 - 7

AC = 40 - 7

AC = 33

The angle sum feature is a characteristic shared by all varieties of triangles. Triangles have an angle sum property of 180 degrees. This indicates that a triangle's internal angles add up to 180 degrees.

The angle 135 ,makes a linear pair with the line

So, the angle will be -

180 - 135

= 45°

Using angle - sum property,

Using a system of equations, it is found that she uses 700 ml of Solution B.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

For this problem, the variables are given as follows:

She uses 400 milliliters less of Solution A than Solution B, hence:

x = y - 400.

Solution A is 20% alcohol and Solution B is 17% alcohol. The esulting mixture has 179 milliliters of pure alcohol, hence:

0.2x + 0.17y = 179.

Since x = y - 400, we have that:

0.2(y - 400) + 0.17y = 179.

0.37y = 259
