[tex](x-4)^{2} + (y-3)^{2} = 5^{2}[/tex]

Step-by-step explanation:

Equation is circle is given as

[tex](x-x_1)^{2} + (y-y_1)^{2} =r^{2}[/tex]

Here [tex](x_1. y_1)=(4, 3)[/tex] and [tex]r=5[/tex]

Equation of circle with center at (4, 3) and radius 5 can be written as

[tex](x-4)^{2} + (y-3)^{2} = 5^{2}[/tex]

Answer:

You can find the scale factor of two triangles by using the ratio of two corresponding sides, so if you begin with smaller figure, your scale factor will be less than one and if you begin with larger figure, your scale factor will be bigger than one.

Answer: C. $67.50

Explanation:

1. Convert 25% into a decimal (0.25)

2. Multiply 90 by 0.25 to get the amount of money discounted. (90x0.25=22.5=$22.50)

3. Subtract 22.5 from 90 to get the sales price. (90-22.5=67.5=$67.50)

Answer

There are 12 coke zeros and 24 coca-colas

Step-by-step explanation:

If there are 36 drinks in total and the shop stocks 3 times as many cokes than coke zeros you would have to divide 36 by 3 and that gets you 12 coke zeros and to check your work you can do 12 times 3 which would be 3 times the cokes which makes a total of 36 and 36 - 12 = 24 cokes.

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:

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:

DAB = BCD

Step-by-step explanation:

DAC = BAC = 90 degrees and DAB = ABC = 90 degrees don't work because they're both equilateral triangles and don't have a right angle that would equal 90. DAB = ABC are clearly not congruent so the answer is DAB = BCD. Also DAB = BCD share the same midsection line.

Answer:

The kind of ice cream the least number of students prefer is Strawberry ice cream.

Step-by-step explanation:

We convert all given values to decimal

Hiroshi found that:

a) For vanilla ice cream

3/5 of his class prefers vanilla ice cream

3/5 to decimal = 0.6

b) For Chocolate ice cream

26% prefers chocolate ice cream

26% to decimal = 0.26

c) For strawberry ice cream

0.14 prefers strawberry ice cream

0.14 = 0.14

Arranging the numbers in order from least to greatest, we have :

0.14, 0.26 , 0.6

The kind of ice cream the least number of students prefer is Strawberry ice cream.

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°.

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.

The correct problem for the fraction 7/8 is 7 divided by 8.

Option C is the correct answer.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

7/8

This is 7 divided by 8.

Thus,

7 divided by 8 is a fraction of 7/8.
