Answer:

The contestant used commutive property!

Step-by-step explanation:

The commutative property of addition simply means that it does not matter in which order we add numbers together. Subtraction is not commutative. This means that the order of the numbers in the subtraction matters.

Answer:

<P = 56 degrees

Step-by-step explanation:

Given the following

m<R = 90 degrees

QR = 61feet = Adjacent

RP = 90 feet= Opposite

Required

tan<P = opp/adj

Tan<P = 90/61

<P = arc tan (90/61)

<P = arctan 1.4754

<P = 55.9

<P = 56 degrees to the nearest degree

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:

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:

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°

Step-by-step explanation:

You have 90° angle and you will get x if you:

x=90°-25°

x=65°

answer:

x= 60 degrees

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).
