The coordinates of B″ if polygon ABCD rotates 270° counterclockwise to create A″B″C″D″ is at (4, 2)

Step-by-step explanation:

A transformation is the movement of a point from its initial position to a new position. If a shape is transformed, all its points are also transformed. Types of transformation are reflection, rotation, dilation and translation.

Given Polygon ABCD is defined by the points A(-4, 2), B(-2, 4), C(1, 3), and D(2, 2).

If a point X(x, y) is rotated 90° counterclockwise, the new location X' is at (-y, x)

If a point X(x, y) is rotated 90° clockwise, the new location X' is at (y, -x)

If a point X(x, y) is rotated 180° clockwise, the new location X' is at (-x, -y)

If a point X(x, y) is rotated 270° counterclockwise, the new location X' is at (y, -x)

Answer: m= 44

Step-by-step explanation:

1/2m - 3/4n = 16    when n is 8  put it into the equation and solve for m.

1/2m - 3/4(8) = 16

1/2m - 6 = 16  

          +6  +6

1/2m = 22

m = 44

Answer:

44

Step-by-step explanation:

● (1/2 )× m - (3/4) × n = 16

Replace n by 8 and the fraction by decimal numbers (1/2 = 0.4 and 3/4 =0.75)

● 0.5 × m - 0.75 × 8 = 16

● 0.5m - 6 = 16

Add 6 to both sides

● 0.5 m - 6 + 6 = 16+ 6

● 0.5 m = 22

Multiply both sides by 2

● 0.5m × 2 = 22 × 2

● m = 44

Answer:

13 cubes, 4 flats, 5 longs

Step-by-step explanation:

Base-ten is basically just analyzing the place values of each number in the given value.

A cube represents 1,000, a flat represents 100, and a long represents 10.

Looking at the number 13,450, we can see that there are 13 thousands in this (13,000). This means that we will need 13 cubes.

We can also see that there are 4 hundreds in this (400), meaning we need 4 flats.

Also, there are 5 tens in this (50), so we need 5 longs.

Answer:

C

Step-by-step explanation:

The central angle of this is 112 degrees. That is CAE is 112 degrees. That being the case, CDE is 90 + 90 + 112  = 292 Tangents make a 90 degree angle with the center of the circle.

CDE = 360 - 292 = 68

C

The measure of ∠CDE is 68degrees

This question bothers on circle geometry;

From the diagram, we can see that ACDE will form a quadrilateral. Since the sum of angles of a quadrilateral is 360degrees, hence;

[tex]<CDE + arcCE+<C+<E=360[/tex]

From the diagram, since CD and DE are both tangential to the circle at point C and E, this shows that <E = <E = 90°

substituting the given values in the formula;

[tex]<CDE+112+90+90=360\\<CDE + 292=360\\<CDE=360-292\\<CDE =68^0[/tex]

Hence the measure of ∠CDE is 68 degrees

Answer:

when two inscribed angles in one circle both equal 75°, the two angles must intercept the same arc that measures 75°.

Step-by-step Explanation:

The relationship between an intercepted arc and an inscribed angle is given as:

the measure of the intercepted arc = twice the inscribed angle that intercepts it.

Also, by virtue of this, when two inscribed angles intercepts the same arc, both inscribed angles are said to be congruent. And the measure of both angles equal the measure of the arc they both intercept.

Therefore, if the measure of an arc, that is intercepted by 2 inscribed angles, is given as 75°, both inscribed angles equal 75° as well. Thus, each of the inscribed angles is half the measure of the intercepted arc.

Therefore, the statement that is true about inscribed angles is: "when two inscribed angles in one circle both equal 75°, the two angles must intercept the same arc that measures 75°."

Step-by-step explanation:

Divide 5.7 by 3 to get your answer.

[tex]\frac{5.7}{3}[/tex] = 1.9

Answer:

$1.90

Step-by-step explanation:

First, write out what you know.

So, you know that you have 3 liters.

Together, they cost $5.70.

You want to know the unit price, for 1 liter.

Therefore, you would divide $5.70 by 3:

[tex]\frac{5.70}{3}=\frac{1.90}{1}=1.90[/tex]

This means that the unit price, for 1 liter of juice, would be $1.90.

Answer:

The answer is below

Step-by-step explanation:

1) The number of rooms Joe company needs is 50. Let the number of rooms needed be n, this can be represented by the inequality:

n ≥ 50

Joe has already reserved 16 rooms, therefore the number of additional rooms needed to be reserved = 50 - 16 = 34 rooms. At least 34 rooms have to be reserved, if B is the number of additional blocks that Joe reserves, the inequality is:

B ≥ 34

2) Each block contains 8 rooms therefore the minimum number of block (a) needed to be reserved = 34/8 = 4.25 = 5 to the next whole number. Therefore the minimum number of blocks needed is given as:

a ≥ 5

Since each block cost $900, let c represent the minimum amount of money needed, therefore the least amount of money needed is given as:

c = $900(5) = $4500

c ≥ $4500

Here, we are required to determine which inequality describes the scenario in the question and the least amount of money that Joe can spend to get the amount of rooms they need.

(1) The inequality which best describes the scenario is; B ≥ 4.25.

(2) The least amount of money that Joe can spend to get the amount of rooms they need is; $4500

The number of blocks he needs to reserve; B ≥ 4.25.

Answer:

100 -6 = 94

94 - 6 = 88

88 - 6 = 82

82 - 6 = 76

76 - 6 = 70      We can then show and prove 70 -> 64.

                                                                          64 -> 58

                                                                          58 -> 52

                                                                          52 -> 46

                                                                          46 -> 40

As numbers that end in 0, decrease to units that end in 4,8,2,6,and back to zero.

= all numbers that end with 0 have numbers that end in 4,8,2,6,0 when subtracting 6.

As 6 x 10 = 60 and 60 +40 = 100

We cna prove 4+8+2+6  = 20

20+20 = 40 and would continue this pattern to get to 10 we can then see the sequence of how 30/6 and proves each 5 number coordinate being 4,8,2,6,0 until we get to 10.

We then find 4,-2,-8,-14,and-20 it skips out  2 and 6 here on the neutral line but then starts and changes the sequence end numbers to -26 -32, -38,-44 and -50. This proves that-2 and -8 has significance and shows us a real sum that on negative -2 -8 = 6

The inverse of the 40 marker in the positive shows us 60

and 60 -50 = 10 being our 2nd positive closest to zero.

These were repeated twice and show 40 deducted and a further 18 as 0 counts for 2 subtractions 100-6  70-6 just like 94 +6 = 100 and like 70+6 = 76 and 40+6 = 46

3 x 6 = 18

40+ 18 = 58

100-58 = 42 and shows us a reflection again with 4 and 2

not just 4+2 = 6 it shows is 4/2 = 2  42/2 = 21 and 7 being a divider represents the first sequence group of 10 from 100 being 70 and just as significant in a decrease of 6 in relation to 100.

100-70 = 30

30-6 = 24

24 / 6 = 4

and we mark 4 as our first unit with relation to 100 and its decrease of 6 in sequence.

This may help you remember that 30 x 100 = 3000 and would be increasing by 6 x 180 times. But when we decrease from here we find 2400 a likely number as 3000-600 - 2400

This may help you remember that 400/6 = 66.6666666667 and why decrease always ends up as negative when 400 x 6 = 2400 and is a much more dividable number. and that 400 is not dividable by 6 in the first place, and may be linked to why a neutral zero number may show 4 and 10 and -2 and -8 where all these numbers divide into 400 6 just doesn't work in any even hundred number below 1200 except for 600 as we know and recall 6 divides into 30 and 18 but not into 40, just counts back to inverse 40 from 100 as its counting 2 x 30 = 60. It does divide into 2400 and that is a midway point back down to 1800 from 3000. So this may help you remember divisors of larger numbers.

(x + 1)^2 = 1/4

Step-by-step explanation:

Here, we want to rewrite the equation by completing the square.

The equation to rewrite is;

4x^2 + 8x + 3 = 0

4x^2 + 8x = -3

divide through by the coefficient of x^2 which is 4

That will give ;

x^2 + 2x = -3/4

Now divide the coefficient of x by 2, square it and add to both sides of the equation.

We have;

x^2 + 2x + 1^2 = -3/4 + 1^2

x^2 + 2x + 1 = -3/4 + 1

x^2 + 2x + 1 = 1/4

= (x + 1)^2 = 1/4

Answer:

6,265 votes

Step-by-step explanation:

The residents of a city voted on whether to raise property taxes. The ratios of yes votes to no votes was 5 to 7. If there were 10,740 total votes, how many no votes were there?

Given that :

Ratio of yes votes to no votes = 5 to 7

Yes votes : no votes = 5 : 7

Total votes = 10,740

The actual number of yes votes and no votes can be obtained thus :

Sum of ratio = (5 + 7) = 12

(ratio of vote / sum of ratio) * total votes

Number of no votes :

(Ratio of no votes / total ratio) * total votes

(7 / 12) * 10,740

0.5833333 * 10,740

= 6,265 votes

Number of no votes = 6,265 votes.
