A team of scientists is traveling by boat to study a pod, or group, of dolphins. The equation y = 0.2x can be used to find the distance, y, in miles the boat travels in x minutes. The dolphins are currently 8.4 mi from the boat. If the dolphins stay to where they are, how long will it take the boat to reach them? Show your work.

Answers

Answer 1

Answer:

42 minutes.

Step-by-step explanation:

We know that:

y = 0.2*x

is the equation that that defines the distance, in miles, that the boat travels in x minutes.

We know that the dolphins are at 8.4 miles from the boat.

Then when we have y = 8.4, this will mean that the boat reached the dolphins.

Then we need to solve the equation:

y = 8.4 = 0.2*x

for x

To do that, we just need to isolate x in one side of the equation, so we can just divide both sides by 0.2 to get:

8.4/0.2 = (0.2*x)/0.2

42 = x

And x is time in minutes, thus, the boat needs to travel for 42 minutes to reach the dolphins.

Greg paid $33 for 2 shirts and $48 for 3 shirts including a fixed shipping fee assuming the same function applies to any numbers of shirts bought how much in dollars would 1 shirt cost before the shipping fee

Answers

Answer:

15 Dollars

Step-by-step explanation:

If you take the shipping price (3 dollars) off you get 15 per shirt

If Greg paid $33 for 2 shirts and $48 for 3 shirts including a fixed shipping fee then one shirt costs $15 before the shipping fee.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given that Greg paid $33 for 2 shirts and $48 for 3 shirts including a fixed shipping fee.

We have to find the cost of one shirt before the shipping fee.

Let x be the cost of one shirt before the shipping fee.

Then, we can set up two equations based on the given information:

2x + shipping fee = 33

3x + shipping fee = 48

We can solve for the shipping fee by subtracting the first equation from the second:

3x + shipping fee - (2x + shipping fee) =48 - 33

x= 48 - 33

x = 15

So one shirt costs $15 before the shipping fee.

Hence, if Greg paid $33 for 2 shirts and $48 for 3 shirts including a fixed shipping fee then one shirt costs $15 before the shipping fee.

Peter bought 5 pens and 8 pencils they cost him 13,25€. How much does one pencil and one Pen cost if the pencil 1,35€ cheaper than the pen

Answers

Answer: 1.85€, 0.5€

Step-by-step explanation:

Given

Peter bought 5 pens and 8 pencils which costs 13.25€

The pencil is 1.35€ cheaper than the pen

Suppose the price of a pen and pencil is x and y

So, we can write

[tex]\Rightarrow 5x+8y=13.25\quad \ldots(i)\\\Rightarrow x-y=1.35\quad \ldots(ii)[/tex]

Solving the above equations, we get

[tex]x=1.85,y=0.5[/tex]

Therefore, the price of a pen and pencil are 1.85€ and 0.5€.

Matt’s gym charges more to reserve the basketball court.

To determine Matt’s cost of reserving the court, look for the difference between the mostly cost each time the court is reserved another time.

The cost of reserving the court one time is: $52.75.

The cost of reserving the court two times is: $55.50.

$55.50 - $52.75 = $2.75, therefore the cost of reserving the court is $2.75.

However it’s important to check your work to make sure that the cost increases by a constant amount. Check the difference between each time the court is reserved another time.

The cost of reserving the court two times is: $55.50.

The cost of reserving the court three times is: $58.25.

$58.25 - $55.50 = $2.75. The cost of reserving the court for a third time is an additional $2.75.

Finally, The cost of reserving the court three times is: $58.25.

The cost of reserving the count a forth time is $61.

$61 - $58.25 = $2.75, therefore the incremental cost of reserving the cost a forth time is $2.75.

Based on the information, Matt’s gym charges $2.75 every time he wants to reserve a court, whereas Tyrell’s gym only charges him $2.00, therefore Matt’s gym charges more.

The rectangular prism’s volume would need to be calculated.

Volume = length * width * height

Volume = 84 * 5 * 2

Volume = 840

The difference needs to be subtracted

840 - 100 = 740

Fill in the value of d = _____ or r = ______
Identify the value of the 5th term: _________

Answers

Answer:

geometric with r = 2

Step-by-step explanation:

An arithmetic sequence has a common difference between consecutive terms

6 - 3 = 3

12 - 6 = 6

24 - 12 = 12

48 - 24 = 24

96 - 48 = 48

As we see the differences are not common, so not arithmetic

A geometric sequence has a common ratio between consecutive terms.

6 ÷ 3 = 2

12 ÷ 6 = 2

24 ÷ 12 = 2

48 ÷ 24 = 2

96 ÷ 48 = 2

There is a common ratio of 2, so sequence is geometric

with 5th term = 48
