Two shops, Tisco and Azda, sell the same brand of baked beans with the following deals.
Alchen [17]

Answer:

The shop with the best value is Tisco with .46 per can.

Step-by-step explanation:

So you need to divide 1.84 by 4 which you get .46.  Next you do 2.40 divided by 5 and you get .48.  Finally you can tell that .48 is greater than .46.

Hope this helps!

What's the area of the triangle below
grigory [225]
To find the area<span> of a </span>triangle<span>, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the </span>area<span> of each </span>triangle<span> is equal to one-half the </span>area<span> of the parallelogram. their is your answer </span>

Question 4
astraxan [27]

Answer:

No real roots

Step-by-step explanation:

The given equations are:

3x-1+2y=0

3x^2-y^2+4=0

We make y the subject in the first equation to get

y=\frac{1-3x}{2}

We substitute into the second expression to get:

3x^2-(\frac{1-3x}{2})^2+4=0

We expand to get:

3x^2-\frac{(1-6x+9x^2)}{4}+4=0

Multiply through by 4 to get:

12x^2-1+6x-9x^2+16=0

3x^2+6x+15=0

The discriminant is given by D=b^2-4ac

D=3^2-4*12*15

D=-711

Since the discriminant is less than zero, the two curves never intersects.

Therefore the system has no real roots

Find the 50th term of the sequence 5, -2, -9, -16, ...
Elodia [21]

Answer:

-338

Step-by-step explanation:

So we have the sequence:

5, -2, -9, -16...

First, note that this is an arithmetic sequence.

This is because each individual term is the previous term <em>added</em> by a common difference.

We can see that this common difference is -7, because each subsequent term is 7 <em>less</em> than the previous one. For example, 5 minus 7 is -2, -2 minus 7 is -9, and so on.

So, to find the 50th term, we can write an explicit formula for our sequence.

The standard form for the explicit formula for an arithmetic sequence is:

x_n=a+d(n-1)

Where a is the initial term, d is the common difference, and n is the nth term.

We can see that our initial term a is 5. And we also already determined that the common difference d is -7. So, substitute:

x_n=5-7(n-1)

Now, to find the 50th term, all we have to do is to substitute 50 for n. So:

x_{50}=5-7(50-1)

Subtract within the parentheses:

x_{50}=5-7(49)

Multiply:

x_{50}=5-343

Subtract:

x_{50}=-338

So, the 50th term is -338.

And we're done!
