Answer:  Oldi gives the best value of money.

Step-by-step explanation:

Lidal's deal : 9 rolls for £3.51

Oldi's deal : 4 rolls for  £1.52

Cost per roll = [tex]\dfrac{\text{total cost}}{\text{Number of rolls}}[/tex]

So,

For Lidal, Cost per roll = [tex]\pounds\dfrac{3.51}{9}=\pounds0.39[/tex]

For Oldi', Cost per roll = [tex]\pounds\dfrac{1.52}{4}=\pounds0.38[/tex]

Clearly,  [tex]\pounds 0.39> \pounds 0.38[/tex]

Hence, Oldi gives the best value of money.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer: 108 liters of gasoline is needed.

Hope this helps! :)

Given parameters:

Distance  = 140km

 Volume of gasoline  = 35liters

Unknown:

Volume of gasoline needed for 432km  = ?

Solution:

Let us first find the rate of gasoline consumption per mile. Using this value, we can then determine the volume of gasoline used for the distance given.

  Rate of gasoline consumption by the boat = [tex]\frac{volume of gasoline}{distance}[/tex]

                                                    = [tex]\frac{35}{140}[/tex]  

                                                    = 0.25liters/km

Now, the volume of gasoline needed for 432km;

   Volume of gasoline needed  = rate of gasoline consumption x distance

                                                    = 0.25 x 432

                                                    = 108liters of gasoline

you good my guy

Step-by-step explanation:

[tex]4+25=2+25[/tex]

They are equal because their sums both equal [tex]29[/tex].

Answer:

4 + 25 is equal to 4 + 25

Step-by-step explanation:

they are equal because both of the equations are the same so that would mean both of the equations would be equal to each other

Answer:

7.639

Step-by-step explanation:

7.639 rounds to 7.64 which is the closest on I could find to 7.62.

Answer:

 I think the answer is 7.636

Step-by-step explanation:

Answer:

[tex]first \: \\ x {}^{2} + x \\ = x(x + 1) \\ \\ second \\ {x}^{2} - 1 \\ = (x) {}^{2} - (1) { }^{2} \\ = (x + 1)(x - 1) \\ \\ third \\ x {}^{2} - x \\ = x(x - 1) \\ \\ therefore \: \: lcm = x(x + 1)(x - 1)[/tex]

Answer:

9c + 8 = 7

Step-by-step explanation:

[tex]-7\sqrt{3}\pi[/tex]

Add similar elements

Answer:

A. [tex]-7\sqrt{3}\pi[/tex]

Step-by-step explanation:

To find the simplified form of that expression, we have to combine like terms. To do this, we should remember that:

ab + cb = (a + c)b

[tex]\pi\sqrt{3}-8\pi\sqrt{3}=(\pi-8\pi)\sqrt{3}=((1-8)\pi)\sqrt{3}=-7\pi\sqrt{3}=-7\sqrt{3}\pi[/tex]

So the simplified form would be [tex]-7\sqrt{3}\pi[/tex].

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:

not very good

Step-by-step explanation:

the correlation should be almost 1  to be a good representation of the data. 0.82 isn't very close.  This would be a pretty "rough" approximation at best.  Maybe that's all that's needed but usually something close to 1.. like 0.99 is needed.

Answer:

(-4, -17), (-3, -10), (-2,5), (-1,2)

All the coordinates are represent linear function.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The coordinates are,

⇒ (-4, -12), (-3,-10), (-2, -8), (-1,-6)

⇒ (-4, -17), (-3, -10), (-2,5), (-1,2)

⇒ (1, -7), (2, -10), (3, -13), (4, -16)

⇒ (1, 1), (2, 4), (3, 7), (4, 10)

Now,

We know that;

A relation between a set of inputs having exactly one output each is called a linear function.

Clearly, All the coordinate have exactly one output for every input.

#SPJ6

Answer:

4

Step-by-step explanation:

Lets make [tex]x[/tex] be the ? in the equation.

That becomes ([tex]x[/tex] x 3) - 3 = 15.

First you have to add 3 on both sides. After doing that it gets to ([tex]x[/tex] x 3) = 15 - 3.

Then you simplify it to 3[tex]x[/tex] = 12.

Now you divide 3 on both sides. That gets to [tex]x[/tex] = 4 after doing it.
