5.123456...- rational and real

√2- real

0 - whole, integers, rational real

Answer:

Step-by-step explanation:

Part A

Since, all angle formed at point F lie on a straight line CE.

Therefore, sum of angles ∠AFE, ∠AFB, ∠CFB will be 180°.

(7x + 4) + (8x + 6) + (6x + 2) = 180

21x + 12 = 180

21x = 168

x = 8

Part B

Two lines CD and AE intersect each other at point F.

Therefore, ∠AFE ≅ ∠DFC [Vertically opposite angles]

m∠CFD = (7x + 4)°

             = 7(8) + 4

             = 60°

Since, all angles formed at point F on a straight line AD are linear angles,

m∠AFB + m∠CFB + m∠CFD = 180°

(8x + 6) + (6x + 2) + m∠CFD = 180°

14x + 8 + m∠CFD = 180

m∠CFD = 172 - 14x

             = 172 - 14(8)

             = 172 - 112

             = 60°

Answer: -5

Step-by-step explanation: whichever number repeats the most is the mode. In this case, -5 repeats 2 times, while the other numbers dont repeat at all.

If we want to write to the mode of -5, -2, -5, -9, -7, 4 is -5

Answer: Median: 44.5 Mode: 45

Step-by-step explanation: Median is the middle number. Since it's an even set, you add the two middle numbers and divide by two. The mode is just the number that appears the most.

Answer:

26

Step-by-step explanation:

40x30%=12

40+12=52

52x50%=26

At a local toy store, extra-large stuffed bears had a price of $40 each.

The price of an extra-large toy stuffed bear is $26.

A percentage is a minimum number or ratio that is measured by a fraction of 100.

At a local toy store, extra-large stuffed bears had a price of $40 each.

In December, the price was raised by 30%.

40 x 30%

= 1200/100

= 12

40 + 12 = 52

In January, the price was lowered by 50%.

52 x 50%

=2600/100

= 26

Thus, the price of an extra-large toy stuffed bear is $26.

Answer:

c=10(g+5)

Step-by-step explanation:

Given that,

The cost of customer smartphone bill is given by the equation as follows :

c=10g+50

Where

g is the number of gigabits of data the customer per month

We need to factor this cost polynomial

The common between 10 and 50 is 10

Taking 10 common. So,

c=10(g+5)

Hence, the required factor is equal to c=10(g+5).

Answer:

225

Step-by-step explanation:

(20*30/2) - (15*10/2)

300 - 75 = 225

Given:

The angles are:

Example [tex]54^\circ[/tex]

1. [tex]63^\circ[/tex]

2. [tex]87^\circ[/tex]

3. [tex]45^\circ[/tex]

4. [tex]72^\circ[/tex]

5. [tex]5^\circ[/tex]

To find:

The complimentary angle of the given angles.

Solution:

If two angles are complimentary, then their sum is 90 degrees.

Example: Let x be the complimentary angle of [tex]54^\circ[/tex], then

[tex]x+54^\circ=90^\circ[/tex]

[tex]x=90^\circ -54^\circ[/tex]

[tex]x=36^\circ[/tex]

Similarly,

1. The complimentary angle of [tex]63^\circ[/tex] is:

[tex]90^\circ -63^\circ=27^\circ[/tex]

2. The complimentary angle of [tex]87^\circ[/tex] is:

[tex]90^\circ -87^\circ=3^\circ[/tex]

3. The complimentary angle of [tex]45^\circ[/tex] is:

[tex]90^\circ -45^\circ=45^\circ[/tex]

4. The complimentary angle of [tex]72^\circ[/tex] is:

[tex]90^\circ -72^\circ=18^\circ[/tex]

5. The complimentary angle of [tex]5^\circ[/tex] is:

[tex]90^\circ -5^\circ=85^\circ[/tex]

Therefore, the complimentary angles of [tex]54^\circ, 63^\circ, 87^\circ, 45^\circ, 72^\circ, 5^\circ[/tex] are [tex]36^\circ, 27^\circ, 3^\circ, 45^\circ, 18^\circ, 85^\circ[/tex] respectively.

Answer/Step-by-step explanation:

Problem 1:

E is the centroid of the triangle.

Centroid theorem states that the centroid is ⅔ of the distance of each vertex to the midpoint of the side opposite each vertex.

This implies that:

AE = ⅔(AD)

AE = 21

Therefore:

21 = ⅔(AD)

3*21 = 2(AD)

(3*21)/2 = AD

31.5 = AD

AD = 31.5

Problem 2: Apply the centroid theorem. Thus:

DE = ⅓(AD)

DE = 12

Therefore,

12 = ⅓(AD)

12*3 = AD

36 = AD

AD = 36
