regular milk has 4% butterfat. how many litres of regular milk must be mixed with 90 l of milk with 1% butterfat to have milk with 2% butterfat?

The two positive coterminal angles are 180° and 540°, the two negative ones are -900° and -180°.

For any given angle A, the family of coterminal angles can be written as:

B = A + n*360°

Where n can be any integer number.

Here we want to find angles coterminal to -540°, so we have the relation:

B = -540° + n*360°

if n = -1 we get:

B = -540° - 1*360° = -900°

if n = 1

B = -540° + 1*360° = -180°

if n = 2

B = -540° + 2*360° = 180°

if n = 3

B =  -540° + 3*360° = 540°

These are the 4 coterminal angles on the given range.

The correct answer is 500 yards. The largest area for the field will be when the cube is a forecourt. With 2000 yds. of fencing, each side would be 2000/4 =  500 yds.

Long, or 500 yds.  If there were no swash also, the largest area would be given by a square configuration since adding the length and dwindling the range of a square by the same value, t will drop the area by a square with sides of length.  Now add the swash on one side. The swash acts like a glass.

As we guard in a cube on one side of the swash, imagine an identical cube on the other side. The maximum area is given when the two blocks form a square, that's when we have a cube doubly as long as wide.

From the given data,

Total pasture area of fencing =2,000 feet

The shape of the field =rectangular

As the area of the rectangle = l*b

So, we can write it as;

2000=x+2y, (As the area of surrounded by a river from one side, so we need to only fence twice of width and only one length (Side) of the rectangle.

Now applying the formula of the area of the rectangle

we will get it as:

Total area of the roof top garden is 272 ft² .

Rooftop planters can have soil depths ranging from six inches at the very least, to allow for little groundcovers and shrubs, to three to four feet, which is necessary for huge shade and coniferous trees. Divide the length by the width of a rectangle or square to find its area.

The square footage of the area is calculated by multiplying the length and width. Please maintain the same unit size (feet or inches). For a rectangular garden area, multiply the length by the width to get the square footage. A suitable garden is often one that is roughly 10 feet by 10 feet, if your landscape permits it (3 x 3 meters).

Given, the figure comprises of triangle and rectangle,

Area of rectangle = length × breadth

= 12 ft × 20 ft

= 240 ft²

Area of triangle = 1/2 × base × height

= 1/2 × 8 × (20 - 12)

= 1/2 × 8 × 8

= 32 ft²

Total area of the figure = Area of rectangle + Area of triangle

so we have hmmm 4 sets above, hmm let's check say the second set, the triangle with sides 5, 9, 3.  Check the picture below.

we have three sides, let's look at the two smaller sides first, 5 and 3.

if we move the sides closer and ever closer to each other, to the extent that one is right on top of the other, what is the length of the red side?  Well, assuming the two smaller sides are one pancaked on top of the other, the red side will be as long as 5 - 3 = 2.  However, the sides can't be on top of each other, because if that's so, we have a flat-line, and thus we wouldn't have a triangle.  So whatever the third side may be, it must be greater than 2.

Now, if we move the sides away from each other, farther and farther to the extent that one is parallel to the other, then the third side will just be as long as 3 + 5 = 8.  However, we can't do that, because if that were to happen, we again will have a flat-line and not a triangle.  So whatever the third side may be, it must be less than 8.

so for those reasons the third side can't be 9, it won't work for a triangle, even 8 is not good, so it must be less.

Now, if we look at the 1st set and 4th set, we end up with the same dilemma, the longest side is too long.

If we take a looksie at the 3rd set however with small sides of 6 and 7, it gives us a third side that must be more than 1 but less than 13, so 7 fits just nicely, so that one works.

The range of the length is 3.2 meters to 3.34 meters

From the question, we have the following parameters that can be used in our computation:

Length of pipe = 3.27 meters

Relative error = 0.07 meters

Represent the range with x

So, we have

|x - Length| = Relative error

substitute the known values in the above equation, so, we have the following representation

|x - 3.27| = 0.07

Remove the bracket

x - 3.27 = 0.07 or x - 3.27 = -0.07

x = 3.2 or x = 3.34

Step-by-step explanation:

x = adult ticket              y = student ticket

5x + 3y = 462

x + y = 130

x + y = 130

y = 130 - x

5x + 3y = 462

5x + 3(130 - x) = 462

5x + 390 - 3x = 462

2x + 390 = 462

2x = 72

x = 36

x + y = 130

36 + y = 130

y = 94

The perimeter of the triangle BCD is 17.25 centimeters.

A closed route that covers, encircles, or outlines a one-dimensional length or a two-dimensional form is called a perimeter. A circle's or an ellipse's circumference is referred to as its perimeter. There are several uses in real life for perimeter calculations.

so, perimeter of the triangle is the sum of all its side length.

Perimeter of one triangle / perimeter of another triangle= side of one triangle by side of another triangle.

let us suppose that the perimeter of triangle BCD is equal to X

27.6/x = 9.6/6

x = 17.25 cm

Based on the analysis, we can be conclude that (C) Driving behavior and gender are related.

The link between variables is described by correlation. It can be viewed positively or negatively, as well as strong or weak. A correlation does not prove a cause. When the variable on the x-axis rises as the variable on the y-axis rises, there is a positive linear association. An upward-sloping straight regression line illustrates this.

When one variable rises while the other falls, there is a negative linear correlation. A straight regression line with a falling slope illustrates this. When there is a relationship between variables, but the relationship is not linear, there is a non-linear correlation (straight).
