Answer:

The simplified expression is:

[tex]\frac{3^9y}{2\times \:81}=\frac{243y}{2}[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{3^9\times \:y}{2\times 81}[/tex]

solving the expression

[tex]\frac{3^9\times \:y}{2\times 81}=\frac{3^9y}{162}[/tex]

        [tex]=\frac{3^9y}{3^4\times \:2}[/tex]                ∵    [tex]162=3^4\times \:2[/tex]      

        [tex]=\frac{3^5y}{2}[/tex]                   ∵   [tex]\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}[/tex]

       [tex]=\frac{243y}{2}[/tex]                  ∵    [tex]3^5=243[/tex]

Therefore, the simplified expression is:

[tex]\frac{3^9y}{2\times \:81}=\frac{243y}{2}[/tex]

Questão completa:

O cronograma de vacinação deste posto pretendia vacinar 1500 moradores do bairro,

porém não conseguiu vacinar todos os moradores. Qual é a probabilidade de escolher

ao acaso um morador do bairro que não tomou vacina?

(eles so conseguiram vascinar 1000 pessoas )

Responda:

1/3

Explicação passo a passo:

Dado que :

Número total de pessoas = 1.500

Número total de vacinados = 1000

Conseqüentemente,

Número de não vacinados = (1500 - 1000) = 500

Portanto, a probabilidade de selecionar aleatoriamente alguém que é vacinado:

Probabilidade = (resultado necessário / número de resultados totais)

P (selecionando alguém que não foi vacinado) =

500/1500

= 1/3 ou 0,3333

Answer:

Yes

Step-by-step explanation:

Yes, Nathan's reasoning makes perfect sense because he is only stating that the money will be enough for the train tickets. Since a ticket for a single student is $200 round-trip and there are a total of 50 students going then that would mean that the total cost is indeed $10,000 (200 * 50). Since they raised a total of $10,880 with the fundraisers that would leave them with $880 ($10,880 - $10,000) after buying all the tickets that they need for all of the students.

Answer:

to find the ammount of twine left we subtract (twine used) from (total twine) or (total twine)-(twine used)=ammount left

so he must cut 42 legnths of rope  each legnth is 4.75 and this is taken from a

total legnth of 240 so

240-42(4.75)=amount left

42 trimes 4.75=199.5

Answer:

y = 1/3x + 8

Step-by-step explanation:

1. Find slope of y = -3x+13

(m = -3)

2. Compute slope for perpendicular line

(m = 1/3)

basically, to find the perpendicular slope, you swap the numerator and denominator of your slope and swap it from negative to positive. (If you started with a positive slope it would turn negative)

3. Find the line with slope m=1/3 that passes through (6,0)

(y = 1/3x + 8)

Step-by-step explanation:

Answer: He ended up with about 1 pound less grapes

Step-by-step explanation:

2 bags of grapes weighing 5 and two-thirds pounds each will give a total weight of:

= 2 × 5 2/3

= 2 × 17/3

= 34/3

= 11 1/3 pounds

3 bags weighing 4 and one-fifth pounds each, will give a weight of:

= 3 × 4 1/5

= 3 × 21/5

= 63/5

= 12 3/5

He ended up buying lesser grapes. This was about 12 3/5 - 11 1/3 = 1 4/15 less. This means that he ended up with about 1 pound less grapes

Add common variables. That's as far as you can go because you don't what the final answer is supposed to be.

Answer:

The coordinates that satisfy the equations will be: (3, 2)

Hence, option C is correct.

Step-by-step explanation:

Given the equations

[tex]x\:-2y\:=-1;\:2x\:+\:3y=12[/tex]

solving the equations to find the solution values (coordinates)

[tex]\begin{bmatrix}x-2y=-1\\ 2x+3y=12\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}x-2y=-1\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2x-4y=-2[/tex]

[tex]\begin{bmatrix}2x-4y=-2\\ 2x+3y=12\end{bmatrix}[/tex]

[tex]2x+3y=12[/tex]

[tex]-[/tex]

[tex]\underline{2x-4y=-2}[/tex]

[tex]7y=14[/tex]

so

[tex]\begin{bmatrix}2x-4y=-2\\ 7y=14\end{bmatrix}[/tex]

solve for y

[tex]7y=14[/tex]

[tex]y=2[/tex]

[tex]\mathrm{For\:}2x-4y=-2\mathrm{\:plug\:in\:}y=2[/tex]

[tex]2x-4\cdot \:2=-2[/tex]

[tex]2x=6[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}2[/tex]

[tex]\frac{2x}{2}=\frac{6}{2}[/tex]

[tex]x=3[/tex]

[tex]\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}[/tex]

[tex]x=3,\:y=2[/tex]

Therefore, the coordinates that satisfy the equations will be: (3, 2)

Hence, option C is correct.

Answer:

well if the x is in the fraction the answer is

x=5

if it is not and it's after the fraction

x=1/5

Step-by-step explanation:

for x=5                                               for x=1/5

Apply;fraction:cross:multiply:          8/12=10/3 x then switch sides

8*3x =12*10                                       10/3 x = 8/12  cancel the common factor:4

simplify:                                             10/3 x = 2/3                                          

24x=120                                            multiply both sides by 3

divide both sides by 24                   3*10/3 x = 2*3/3

24x/24=120/24                                 simplify: 10x =2

simplified =5                                    divide both sides by 10: 10x/10=10/2

x=5                                                    simplified = 1/5

                                                          x=1/5

Answer:

if you increase by 4%, it means you will have a new total of 104%. In decimals it is 1.04 (divide your percentage by 100) after that you do the same with the 3% increase. you'll have a new total of 103%. In decimals 1.03. If you want to know what single multiplier you can use, you need to multiply the both decimals. So you get 1.04 x 1.03 = 1.0712

Step-by-step explanation:

The decimal multiplier would you use to increase by 4% followed by a 4% decrease is 1.0816.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

We have to find decimal multiplier would you use to increase by 4% followed by a 4% decrease.

So, (1+ 4%)(1+ 4%)

= (1 + 4/100)(1 + 4/100)

= (1 + 0.04)(1+0.04)

= 1.04 x 1.04

= 1.0816

Answer:

(x - 20)(x + 3)

Step-by-step explanation:

Multiply the coefficient of the first term. 1 x -60

which equals -60

find the two factors of -60 which is -17

-60+ 1 = -59

-30+ 2= -28

-20+ 3= -17

Then, the final answer you will get is  (x - 20)(x + 3)

Answer:

[tex]Probability = \frac{1}{11}[/tex]

Step-by-step explanation:

Given

[tex]Blue = 4[/tex]

[tex]Green = 6[/tex]

[tex]Red = 2[/tex]

[tex]Total = 12[/tex]

Required

Determine the probability of drawing red and green without replacement

This is calculated as follows:

[tex]Probability = P(Red\ and\ Green)[/tex]

[tex]Probability = P(Red)\ and\ P(Green)[/tex]

[tex]Probability = \frac{n(Red)}{Total} * \frac{n(Green)}{Total - 1}[/tex]

We used Total - 1 because it's a probability without replacement:

[tex]Probability = \frac{2}{12} * \frac{6}{12- 1}[/tex]

[tex]Probability = \frac{2}{12} * \frac{6}{11}[/tex]

[tex]Probability = \frac{1}{6} * \frac{6}{11}[/tex]

[tex]Probability = \frac{1}{11}[/tex]

Hence, the required probability is 1/11
