Tagged *2008: 40 *2009: 16 *2010: 8 total caught *2009: 50 *2010: 30 Now, you can compare them. Like so, let's use the first one. You can compare the ratio of 16/40 = 50 / x where x is the total population so basically the proportion above represents that 16 of the 40 tagged were caught and it relates proportionately to the number of turtles caught out of the entire population of turtles that were currently there in 2009. Now, you can cross multiply to get this... 16/40= 50/x 16x = 2000 then divide by 16 x = 125 125 represents the total population Set up the other proportion just likes this and you should be able to get the population for 2010 as well. There are other ways to set it up though if you want to experiment on your own. Hope this helped.

The revenue of a company that makes backpacks is given by the formula R = 34.S0x, where x represents the number of backpacks sol

alexgriva [62]

Answer:

Revenue = 1380

Step-by-step explanation:

Given:

Revenue means the sales or turnover of a company when it sells its products. In other words, it is nothing but the income of a company on selling the products.

Here, the company is selling backpacks. So, revenue is the amount earned by the company on selling 'x' backpacks. The linear model to represent the same is given below.

The revenue received from selling 'x' backpacks is given as:

$R=34.50x$

Number of backpacks sold (x) = 40

Now, in order to find the revenue received on selling 40 backpacks, we need to plug in 40 for 'x' in the equation above and solve for the revenue, 'R'.

On plugging 40 for 'x', we get:

$R=34.50\times 40\\\\R=1380$

Therefore, the revenue received by the company on selling 40 backpacks is 1380.

Can anyone help me with this?

Answer:

D. -6m²n² + 10m²n + 8mn² - 10mn

Step-by-step explanation:

(-7mn + 8mn² - 8m²n²) + (10m²n + 2m²n² - 3mn)

Apply the distributive property to remove the parentheses

-7mn + 8mn² - 8m²n² + 10m²n + 2m²n² - 3mn

Combine like terms together and arrange in standard form

-7mn + 8mn² - 8m²n² + 10m²n + 2m²n² - 3mn

-8m²n² + 2m²n² + 10m²n + 8mn² - 7mn - 3mn

-6m²n² + 10m²n + 8mn² - 10mn
