A car can travel 480 miles on a full tank of petrol. The tank holds 60 litres. The fuel gauge shows there and 15 litres left in the tank. How many more miles can the car travel before it runs out of petrol?

Answers

Answer:

Miles= 120

Step-by-step explanation:

Giving the following information:

A car can travel 480 miles on a full tank of petrol. The tank holds 60 liters.

First, we need to calculate the miles per liter:

Miles per litre= 480 / 60

Miles per litre= 8 miles

Now, the miles that can be driven with 15 liters:

Miles= 15*8

Miles= 120

Five different awards are to be given to three students. Each student will receive at least one award. In how many different ways can the awards be distributed?

Answers

Answer:

Two ways

Step-by-step explanation:

Blue is students and Yellow is the trophies.

Total number of different ways that the awards can be distributed is; 150 ways.

It is clear from the question that the awards and the students are different. Now, each student will receive at least one award.

This means that the five different awards could be separated into;

3 + 1 + 1 awards or 2 + 2 + 1 awards.

Now, for one person to get 3 awards and the other 2 people to get one award each, the number of ways is calculated as;

       ⁵C₃ × 3! = 60 ways

Now, for the case where one person is to get 1 award and the other 2 people to get two awards each, the number of ways is calculated as;

      ((⁵C₂ × ³C₂)/2) × 3! = 90 ways

Thus; total number of ways the awards can be distributed = 60 + 90 = 150 ways.

What are the negative and positive coterminal angles of 240 degrees?

Answers

-120 negative and 600 positive.

The negative and positive coterminal angles of 240 degrees will be -120 negative and 600 positive.

What are coterminal angles?

Two different angles that have identical starting and ending edges are termed coterminal angles however since one angle is measured clockwise and the other is determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.

We have to find the coterminal angles of 240 degrees

Coterminal angles are those whose initial and terminal sides coincide. Depending on whether the given angle is in degrees or radians, adding or subtracting 360° or 2 from each angle yields the coterminal angles. There are countless coterminal angles that can be discovered.

Thus, the negative and positive coterminal angles of 240 degrees will be -120 negative and 600 positive.

Can someone plz help me with this????

Answers

what information are you given??

Answer:

since we cant see what info is given maybe these tips can help...

the 'b' is also called the y-intercept, the y-int is what you start of with. Example, if your parents give you $20 and you spend $5 every week, your y-int is 20

The m is the slope, so if your parents give you $20 and you spend $5 every week, your slope is -5 because your money is decreasing at a linear rate

the x is the input, so if you want to know how much money you have 2 weeks after you got $20, you would substitute x with 2, and solve to get $10

Create a 5th degree trinomial that has a constant term of 3.

Answers

Answer:

[tex]2x^5+3x^2+3[/tex] is a trinomial having with:

three terms degree 5 and The constant term '3'

Step-by-step explanation:

Considering the trinomial

[tex]2x^5+3x^2+3[/tex]

Any polynomial with 3 terms is a trinomial, so it is a trinomial.

It is clear that '5' is the highest power of the 'x' variable. so, the polynomial has a degree of 5.

'3' is the constant term. The reason is that any term with no variable is called a 'constant' term. So, '3' is the constant term.

Therefore, [tex]2x^5+3x^2+3[/tex] is a trinomial having with:

three terms degree 5 and The constant term '3'
