Given that 3x : 8 = 9 :2 , find the value of x .

Respuesta:

1/16

Explicación paso a paso:

Dada la secuencia geométrica: 32, 16, 8, 4 ................,

El enésimo término de una progresión geométrica se obtiene mediante la relación:

enésimo término = ar ^ (n-1)

Dónde ; a = primer término = 32; n = enésimo término; r = razón común

r = a2 / a1 = a3 / a2

r = 16/32 = 8/16

r = 1/2

Por lo tanto, el décimo término:

n (10) = 32 * (1/2) ^ (10 - 1)

n (10) = 32 * (1/2) ^ 9

n (10) = 32 * (1/512)

n (10) = 32/512

n (10) = 1/16

Por lo tanto, el décimo término es 1/16

Answer:

$4500

Step-by-step explanation:

Find how much she earned by dividing 234 by 0.052

234/0.052

= 4500

So, she earned $4500

Answer: see below

Step-by-step explanation:

Divide 234 by 5.2 to get one percent of her earnings, $45.

Multiply 45 by 100 to get 100% of her earnings, $4,500

If it asking for the gross earnings, leave it at $4,500

If it is asking for net earnings, subtract 234 from 4500 to get $4,266

Answer:

6 or A

Step-by-step explanation:

Let's say n is equal to f(x). So "n is equal to g(x) and g(x) is equal to 3c + f(x) - 15 so when

n = 9 and c = 4 when I substitute I get 3(4) + (9) - 15 = 12 + 9 -15 = 21 - 15 = 6

Answer:

3 runners will be in the last group

Step-by-step explanation:

So first you need to divide the 819 runners into 6 different groups. Once you do this... you get a total of 136. So there are 136 runners in each of the 6 groups. However, once you get to the end of the division problem, there is a remainder of 3. These three stand for the last 3 runners. Giving you your answer.

I hope this helps you!!!

Answer: 20/21 gallons

Step-by-step explanation:

From the question given, we are informed that Maleah turned on the water in the kitchen and that for every 1 3/4 minute, 1 2/3 gallons of water went into the sink.

The number of gallons of water that filled the sink per minute will then be calculated as:

= Amount of gallons of water that went into sink / Number of minutes used

= 1 2/3 ÷ 1 3/4

= 5/3 ÷ 7/4

= 5/3 × 4/7

= 20/21

Therefore, 20/21 gallons of water filled the sink per minute

Step-by-step explanation:

Here are the steps required for Solving Quadratics by Factoring:

Step 1: Write the equation in the correct form. To be in the correct form, you must remove all parentheses from each side of the equation by distributing, combine all like terms, and finally set the equation equal to zero with the terms written in descending order.

Step 2: Use a factoring strategies to factor the problem.

Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.

Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.

Example 1 – Solve: x2 + 16 = 10x

Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.

Step 1

Step 2: Use a factoring strategies to factor the problem.

Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.

simplify = 27/8

Step-by-step explanation:

Answer: I think the answer might be 9.28.

Step-by-step explanation:

I was also confused with this question so I might be wrong.

Using the information provided above I was able to conclude that two possible equations you can form is A+B=17.18, where there is only 1 stock from company A and 1 stock from company B. The other equation is 52A+65B=1,014 since this is the total amount she spend on the stocks.

You can use Desmos to graph both of the equations or solve it by hand. If solving it by hand chose which method you wanna use wether it is elimination or substitution. (I would explain the process, but I am lazy)

Answer:

The correct option is (b).

Step-by-step explanation:

We need to find the probability of getting 5 when Janet rolls a regular eight-sided die with numbers 1 to 8.

The formula for probability of getting an event is given by :

[tex]P=\dfrac{Favourable\ outcome}{Total\ no\ of\ outcomes}[/tex]

Here, favourable outcome = 1

Total outcomes = 8

So,

[tex]P=\dfrac{1}{8}[/tex]

So, the correct option is (b).
