Answer:

5,040 cars

Step-by-step explanation:

Each truck weighs 7.2 tons, and there are already 480 trucks loaded. This means that the cargo ship is currently carrying 3,456 tons.:

480 x 7.2 = 3,456

The limit is 21,600 tons, so 21,600 - 3,456 = 18,144.

Divide the remaining capacity by how much a car weighs:

18,144 / 3.6 = 5,040

Answer:

(a) $R(x)=-0.02x^2+610x$

(b) $R'(x)=-0.04x+610$

(c)R'(5400)=$394

Step-by-step explanation:

Given that x is the quantity demanded and the speaker's unit price (in dollars) is p where:

p = −0.02x + 610 (0 ≤ x ≤ 20,000)

(a)Revenue function R.

Revenue = Price X Quantity Demanded

Therefore:

R(x)=xp

$=x(-0.02x + 610)\\R(x)=-0.02x^2+610x$

(b)Marginal revenue function R'(x)

If $R(x)=-0.02x^2+610x$

Then, the marginal revenue function

$R'(x)=-0.04x+610$

(c)We want to compute R'(5,400)

$R'(5400)=-0.04(5400)+610\\R'(5400)=394$

From the above, we can infer that the revenue that will be generated on the sales of the 5401st item is $394.

Tasty Things Bakery recently sold 20 desserts, including 8 brownies. Considering this data, how many of the next 5 desserts sold

Agata [3.3K]

Answer:

About 2 of their next 5 deserts sold would be brownies.

Let's represent this by fractions. If 8 out of the 20 desserts they sold were brownies, that would make the fraction 8/20 represent how many brownies were sold.

Now if you reduce this fraction, you get 2/5, which tells about how many brownies will be sold in the next 5 brownies judging by the other data.

Which of the following is the equation of a line parallel to the line y = 3x + 2,

earnstyle [38]

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 is in this form with slope m = 3

• Parallel lines have equal slopes, hence

y = 3x + c ← is the partial equation of the parallel line

To find c substitute (10, 1) into the partial equation

1 = 30 + c ⇒ c = 1 - 30 = - 29

y = 3x - 29 ← in slope- intercept form

Subtract y from both sides

0 = 3x - y - 29 ( add 29 to both sides )

29 = 3x - y, thus

3x - y = 29 ← in standard form → B
