Answer:

E. 36

Step-by-step explanation:

Let:

C_1 = color 1

C_2 = color 2

C_3 = color 3

Case I

C₂      C₃       C₂

C₃      C₁        C₃

C₁       C₂       C₁

Since C₁ has 3 choices, then C₂ has 2 choices and C₁ has 1 choice

number of combinations = 3 × 2 × 1 = 6

Case II

C₂      C₃       C₁

C₃      C₁        C₂

C₂       C₃       C₁

Since C₁ has 3 choices, then C₂ has 2 choices and C₁ has 1 choice

number of combinations = 3 × 2 × 1 = 6

Case III

C₁      C₃       C₂

C₂      C₁        C₃

C₃       C₂       C₁

Since C₁ has 3 choices, then C₂ has 2 choices and C₁ has 1 choice

number of combinations = 3 × 2 × 1 = 6

Case IV

C₂     C₃         C₁

C₃      C₁        C₂

C₁       C₂       C₃

Since C₁ has 3 choices, then C₂ has 2 choices and C₁ has 1 choice

number of combinations = 3 × 2 × 1 = 6

Case V

C₁      C₂         C₁

C₃      C₁        C₃

C₂      C₃       C₂

Since C₁ has 3 choices, then C₂ has 2 choices and C₁ has 1 choice

number of combinations = 3 × 2 × 1 = 6

Case VI

C₁      C₂         C₃

C₃      C₁        C₂

C₁       C₂       C₃

Since C₁ has 3 choices, then C₂ has 2 choices and C₁ has 1 choice

number of combinations = 3 × 2 × 1 = 6

Therefore, the total combinations = 6 + 6 + 6 + 6 + 6 + 6

= 36

Which equation represents a function of x that is not linear?
AnnyKZ [126]

Answer:

y = 4x+3x^2

Step-by-step explanation:

For an equation to be linear, x must have a power of 1

y = 4x+3x^2 has a power of x that is not x  ( x^2) so this is not linear  ( it is quadratic)

A store buys purses for $24.50 and then marks them up 25%. The store then discounts any purses that do not sell in the first mon
Sergeu [11.5K]

Answer:$27,57

1)find out how much wallets cost in the first month:

24,50 -100%

х      - 125%

х= 24,50*125/100 ≈ 30,63

2)we will find out how much the wallets cost after the price is reduced by 10%:

30,63 - 100%

х         -90%

х=30,63*90/100 ≈ 27,57

Help math homework both questions
-Dominant- [34]

Answer:

Q-12 The vertical length of the top part of elevator to ground is 0.8484 meters .

Q -14 The glide runway path is 24,752.47 feet .

Step-by-step explanation:

Q - 12

Given as :

The diagonal length of the elevator = e = 1.2 meters

The vertical length of the top part of elevator to ground = x meters

The angle made by elevator with ground = Ф = 45°

<u>Now, According to figure</u>

Sin angle = \dfrac{\textrm perpendicular}{\textrm hypotenuse}

Or, Sin Ф = \dfrac{\textrm x}{\textrm e}

Or, Sin 45° =  \dfrac{\textrm x meters}{\textrm 1.2 meters}

Or, 0.707 × 1.2 meters = x

∴ x =  0.8484 meters

So, The vertical length of the top part of elevator to ground = x = 0.8484 meters

Hence,The vertical length of the top part of elevator to ground is 0.8484 meters .  Answer

Q-14

Given as:

The altitude of decent of plane = H = 10,000 feet

The angle of descend =  Ф = 22°

Let the glide runway path = y feet

<u>Now, According to question</u>

Tan angle = \dfrac{\textrm perpendicular}{\textrm base}

Or, Tan Ф = \dfrac{\textrm H}{\textrm y}

Or, Tan 22° =  \dfrac{\textrm  10,000 feet}{\textrm y feet}

Or, 0.4040 =  \dfrac{\textrm  10,000 feet}{\textrm y feet}

Or, y =  \dfrac{\textrm  10,000 feet}{\textrm 0.4040}

∴   y = 24,752.47

So,The glide runway path = y = 24,752.47 feet

Hence, The glide runway path is 24,752.47 feet . Answer

Scott collects hats. He has 65 hats an plans on buying 80 per year.
kicyunya [14]

Answer:

80x+65 2.465 3.865

Step-by-step explanation:

x being the number of years so in ten years he will have 80x10=800+65=865

80x5=400+65=465 so 5 is the number of years it would take

and i do not understand number 1 but i put a formula just in case that was it
