Answer:

A

Step-by-step explanation: You have two variables, the time and the number of cartons. If time wasn't a variable here, the number of cartons would remain static. You need time, otherwise there would be no change. Now that you know there are two variables, the last two choices must not be correct. Between A and B, the difference is that A says every dip is a purchase and B says every horizontal line is a purchase. Obviously, a horizontal line doesn't mean a purchase; it means the time gone WITHOUT  a purchase. This leaves you with A.

x = 3 +√43, x = 3 - √43

Step-by-step explanation:

x^2 - 6x - 34 = 0

move the 34 across

x^2 - 6x = 34

take -6 and divide by two, then square it

(-6/2)^2 = 9

add the product to your equation

x^2 - 6 + 9 = 34 + 9

solve

(x - 3)^2 = 43

x - 3 = ± √43

x = 3 ± √43

Step-by-step explanation:

x=7

Q 1)

3(x + 5) = 36

3x + 15 = 36

3x = 36 - 15

3x = 21

x = 21/3

x = 7

Verification:

3(x + 5) = 36

3(7 + 5) = 36

A bag contains 120 balls. The ratio of red to blue balls is 10:2

Find how many red and blue balls there are

Answers

Answer:

100 red balls and 20 blue balls.

Step-by-step explanation:

So to find out what you need to multiply the ratio by to get the answer, you add 10 and 2. That's 12. 120/12 is 10. 10:2 times 10 = 100: 20, so there are 100 red balls and 20 blue balls.

Dessa forma, a densidade demográfica de São Paulo é de, aproximadamente,

Answers

Responda:

Explicação passo a passo:

Dado que:

Densidade populacional = razão entre o número de habitantes e a área

Número de habitantes em São Paulo = 45 milhões

Área do estado de São Paulo = 248210 km²

Portanto, a densidade populacional de São Paulo:

Número de habitantes / área

45.000.000 pessoas / 2.48210 km²

Playing cards numbered from 1 to 20 are mixed thoroughly and kept it in a box. One card is taken at random from the box. What is the probability of the selected/drawn playing cards?1. Is a Prime number.2. A factor of 20.3. A composite number.4. A multiple of 3.5. A perfect square.

Answers

Step-by-step explanation:

Probability is the ratio of the expected outcome (event) to the total outcome (sample space)

Probability = expected outcome/total outcome

If Playing cards numbered from 1 to 20 are mixed thoroughly and kept it in a box, the total number of sample space is 20

1) To calculate of getting a prima number.

Events = {2, 3, 5, 7,11,13,17,19}

n(events) = 8 elements

Pr(selecting a prime) = 8/20 = 2/5

2) If a factor of 20 is selected

Factor of 20 F = {2, 4, 5, 10, 20}

n(F) = 5

Pr(factor of 20) = 5/20 = 1/4

3) A composite number are 2 digits numbers.

Composite number C = {10,11,12,13,14,15,16,17,18,19,20}

n(C) = 11

Pr(a composite number) = 11/20

4) For multiple of 3.5

Multiple of 3.5 M = {3.5, 7.0, 10.5, 14.0, 17.5}

n(M) = 5

Pr(multiple of 3.5) = 5/20 = 1/4

5) For perfect squares

Perfect squares P = {1, 4, 9, 16}

n(P) = 4

Pr(perfect squares) = 4/20 = 1/5

When given two coordinates, you must use this formula to find the slope of a line:

[tex]m= \frac{y_{2} - y_{1}}{x_{2}-x{1}}[/tex]

where m is your slope.

So, plug in your coordinates. Remember, a coordinate is denoted by (x,y). So, for example, your [tex]x_{1}[/tex] would be -18 and your [tex]x_{2}[/tex] would be 19.

[tex]m =\frac{4--13}{19--18}[/tex]

[tex]m =\frac{17}{37}[/tex]

Zachary purchased a computer for $1,300 on a payment plan. Two months after he purchased the​ computer, his balance was $1,100. Four months after he purchased the​ computer, his balance was $900. What is an equation that models the balance y after x​ months?

Answers

Answer:

y = 1300 - 100x

Step-by-step explanation:

Zachary purchased a computer for $1300

The first step is to calculate the purchase he paid after 2 months

= 1,300-1,100

= $200

Then the purchase after 1 month is

= $200/2

= $100 per month

The purchase made after 4 months is

= 1,100-900

= $200

The purchase after a month is

= $200/2

= $100 per month

Therefore the equation that models the balance y after x months is

= initial amount of payment plan - amount per month

y= 1,300 - 100x

Belmont is a growing industrial town. Every year, the level of CO2 emissions from the town increases by 10%. If the town produced 330,000 metric tons of CO2 this year, how much will be produced 6 years in the future? If necessary, round your answer to the nearest whole number

Answers

Answer:

584,615

Step-by-step explanation:

its rounded by the whole number

Belmont will produce 584,615 metric tons of CO₂ after 6 years, growing at the rate of 10% every year, currently emitting 330,000 metric tons of CO₂.

What do we mean by growth?

The value of most things is not constant in this world. If we observe correctly, the value of some of the things rises, while others fall. If there is a rise, we call it growth.

Growth can be determined by the formula,

V = V₀(1+r)ⁿ, where V is the final value, V₀ is the initial value, r is the rate and n is the time.

How do we solve the given question?

In the question, we are given that Belmont is a growing industrial town. Every year, the level of CO2 emissions from the town increases by 10%.

We are asked that if the town produced 330,000 metric tons of CO2 this year, how much will be produced 6 years in the future.

As we see that the amount of CO₂ emission is growing, to find the amount of CO₂ emitted in the 6th year, we use the growth formula,

V = V₀(1+r)ⁿ, where V is the final value, V₀ is initial value, r is rate, and n is the time period.

Here, V₀ = 330,000 metric tons, r = 10%, n = 6 years.

∴ V = 330,000(1 + 10%)⁶

or, V = 330,000(1.1)⁶ = 330,000*1.771561 = 548615.13

or, V = 548615 metric tons (rounded to nearest whole number).

∴ Belmont will produce 584,615 metric tons of CO₂ after 6 years, growing at the rate of 10% every year, currently emitting 330,000 metric tons of CO₂.
