Part A: Sam rented a boat at $225 for 2 days. If he rents the same boat for 5 days, he has to pay a total rent of $480.
klemol [59]

Answer:

y = 85x + 55

Step-by-step explanation:

If we use the given prices as coordinates we will get the coordinates (2, 225) and (5, 480) and if we use the rise over run which in this case is 255/3 then we get the slope which is $85 and now we plug what we know into y = mx + b. we now have the equation 225 = (85)2 + b which can be simplified to 55 = b and now we can create the equation y = 85x + 55.

Hope this helps and please mark brainliest :)

A-Plus Printers charges a one-time fee of $26 plus $.12 per flyer to print and deliver
Lena [83]

for 201 onwards we will see that the cost in A-Plus Printers less than the cost at Print-and-More

<h3>For how many flyers is the cost at A-Plus Printers less than the cost at Print-and-More?</h3>

A-Plus Printers charges $26 plus $0.12 per flyer, so if you print x flyers, the total cost is:

f(x) = $26 + $0.12*x

For Print-and-More, they charge only $0.25 per flyer, so here the equation is:

g(x) = $0.25*x

Here we need to see for which value of x the costs are the same:

f(x) = g(x)

$26 + $0.12*x =  $0.25*x

Now we can solve that linear equation for x:

$26 = $0.25*x - $0.12*x

$26 = $0.13*x

$26/$0.13 = 200

This means that for 200 flyers, the cost is the same in both places, then for 201 onwards we will see that the cost in A-Plus Printers less than the cost at Print-and-More.

While evan and sam are fishing 12kms from shore, their boat springs a leak, and water comes in at a constant rate of 3 gallons p
aev [14]

Based on the calculations, the slowest rate is equal to 4 gallons per minute.

<u>Given the following data:</u>

  • Distance from shore = 12 km.
  • In-rate = 3 gallons per minute.
  • Rowing rate = 24 km per hour.

<h3>How to calculate the slowest rate.</h3>

Let's assume the boat would sink if it takes in more than 20 gallons of water.

<u>Conversion:</u>

  • 24 km/h to km/min = \frac{24 }{60} = 0.4 km/min.

Translating the word problem into an algebraic expression, we have;

\frac{12}{0.4} \times 3 - \frac{12}{0.4} \times x\geq 30\\\\\frac{36}{0.4}-\frac{12x}{0.4} \geq 30\\\\90-\frac{12x}{0.4} \geq 30\\\\\frac{12x}{0.4} \geq90+30\\\\\frac{12x}{0.4} \geq120\\\\12x \geq120 \times 0.4\\\\12x \geq 48\\\\x\geq 4

Therefore, the slowest rate is equal to 4 gallons per minute.

If an object is projected upward with an initial velocity of 126ft per? sec, its height h after t seconds is h=?16t^2+126t. Find
Archy [21]

Answer:

=760 ft

Step-by-step explanation:

h=16t^2+126t

Let t=4

h = 16 (4)^2 +126(4)

h = 16*16 +126(4)

  =256+504

   =760 ft
