Answer:

16

Step-by-step explanation:

The distance is given by

d = sqrt( (x2-x1) ^2 + ( y2-y1) ^2)

Since the x values are the same

d = sqrt(  ( y2-y1) ^2)

d = sqrt(  (( -6 - 10)^2))

d =  sqrt((-16) ^2)

d = 16

We can also just find the number of squares between the points since the x value is the same.

Answer:

Step-by-step explanation:

Consecutive interior angles have a sum of 180°, so ...

  (41 +7x) +(11x -5) = 180

  18x +36 = 180 . . . . . . . . . simplify

  x + 2 = 10  . . . . . . . . . . . . divide by 18

  x = 8

The angle 7x is then ...

  7x = 7(8) = 56 . . . . degrees

The angle 11x -5 is ...

  11x -5 = 11(8) -5 = 83 . . . . degrees

Check

41 + 56 + 83 = 97 +83 = 180 . . . . as required

Answer:

According to the above problem

[tex](7x) + (11x - 5) + 41 = 180 \\ 18x = 180 + 5 - 41 \\ 18x = 144 \\ \boxed{x = 8}[/tex]

Therefore, the angles are 41°, 56° and 83°.

The area of the composite figure that is formed from a rectangle and triangle is 100 cm²

The area of the composite figure is the sum of the area of the whole figure.

Therefore, the composite figure can be divided into a triangle and a rectangle.

Hence,

area of rectangle = lw

where

area of the rectangle = 14 × 5 = 70 cm²

area of triangle = 1 / 2 bh

where

Therefore,

area of a triangle = 1 / 2 × 12 × 5

area of a triangle = 30 cm²

area of the composite figure = 30 + 70 = 100 cm²

Answer:

A solution to a linear equation means that the ordered pair is a point that lies on that line.

If someone were to say (2,5) is a solution to the equation y= 2x+3, you could check them by plugging in 2 where the variable "x" and seeing if y =5.

In this case,

y= 2(2)+3

y=7

(2,5) is not a solution.

Answer:

$3200

Step-by-step explanation:

The total area of land is 30 acre. Let x represent the area in acre that corn is planted and y represent the area in acre that wheat is planted. Therefore:

x + y = 30               (1)

Also, the farmer can spend at most $750 on seeds. Corn cost $15 per acre, maize cost $30 per acre. Hence:

15x + 30y ≤ 750      (2)

Also, x and y > 0

The profit is given by the function:

Profit = 100x + 110y

Graphing equation 1 and equation 2 and solving, we get the points:

(10, 20)

Hence the maximum profit is at:

Max profit = 100(10) + 110(20) = $3200

Answer: Working or doing homework in bed will reduce one's focus because most people tend to associate their beds with comfort and sleep. Doing such activities in bed can lead to a deviation of the brain to become more lazy and possibly fall asleep.

Disadvantages of studying in bed includes issues related to posture and concentration. Hence, studying in bed often ;

A bed is primarily meant for sleeping while desks and chairs are made for studying. The difference in the build is due to the purpose of nature of each activity. Studying in an environment meant for sleeping would most likely induce sleep.

The number 2000 is 10 times as much as the number 200.

The number 0.5 is 1/10 as much as the number 5.

Answer:

There are a variety of factors driving the

adoption of 415/240VAC distribution. First,

distributing at these increased voltages

enables overall efficiency to be enhanced

by eliminating the need for a voltage

transformation along the power path. For

example, in a 415V system, the L-N voltage

is 240V, which is compatible with most all IT

loads. By shifting the UPS output distribution

voltage to 415/240 V three-phase (L-L/

L-N), most of the existing servers today can

be powered with 240V single-phase (L-N)

without any intermediate transformation.

Removing the need for a transformer

streamlines the power path and can increase

efficiency approximately 1.5 percent.

The adoption of a 415/240VAC distribution

model also can yield additional savings at

the device-level in the form of increased

efficiency for server power supplies. As

previously mentioned, today’s power

supplies can handle a wide range of incoming

voltages. Based on the actual voltage being

fed into the power supply, efficiencies can

range from as low as 80 percent (at 100V

nominal) to as much as 94 percent (at 240V

nominal) across all manufacturers.

Furthermore, while the typical efficiency

differential between 240V and 208V gained

at the server power supply today is a relatively

minimal, only 0.3 percent across most of

the load range, the efficiency differential

between 240V and 120V servers can be as

much as 2 percent for a given power supply.

It is this value that often gets overstated by

some manufacturers when comparing 415V

distribution to “traditional methods,” as

there are relatively few servers or peripherals

installed today that are operating at 120V.

Answer:

Markup is how much to increase prices and markdown is how much to decrease prices. If we are given a markdown percentage, we multiply the percentage with the original price to find how much of a decrease we are getting, then we subtract this difference from the original price to find the marked down price.

Step-by-step explanation:

9514 1404 393

Explanation:

Markup is the name given to the difference between a cost price and a selling price:

  cost price + markup = selling price

Markdown is a name given to the difference between a list price or tag price and the actual selling price.

  list price - markdown = selling price

Markup and markdown are actual currency amounts. Often, sellers relate them to the cost price or the list price using percentages. That is, the percentage markup can be figured as ...

  percent markup = (markup)/(cost price) × 100%

Similarly, the markdown may be expressed as a percentage of the selling price:

  percent markdown = (markdown)/(selling price) × 100%

__

Additional comments

These representations as percentages are often used because a seller is usually interested in having a specific percentage return on money invested. By making the markup a specific percentage of the cost price, that return can be ensured.

Markdown percentages are often important to a buyer. They look for sales that offer a large percentage discount (markdown), sometimes not paying so much attention to the list price.

An approximate match

Step-by-step explanation:

The vlookup (vertical lookup) function is a search function in excel used in locating values in an excel table.

The vlookup syntax is written as:

=VLOOKUP(value, table, col_index, [range_lookup])

The range_lookup is an optional parameter which is used to indicate if the search should be for an exact match or approximate match. Since a column, resort fee will be used as a possible additional cost; the search would be required to return an approximate search rather than an exact match in other for the search condition to be adequately implemented.

The type of match to use in a Vlookup() function to assess the resort fee as a possible additional cost for a particular room is

This refers to the possible cost when the Vlookup() function is used as it is used as a search function to find the values which are in a database table.
