Final Exam accounts for 65% of total.

The rest is 100 - 65 = 35%

On the 35%, he has 74% or 74 out of 100.

Let's say the final exam is out of 100 and we want to find how much he can afford to get to take him to "B".

Let's say his score needs to be "x" in order to get B.

The overall weighted average of the course would be counted as:

Breaking it down:

74 out of 100 means WHAT out of 35? (let's call the unknown "y")

y would be:

So, he currently has 25.9 out of 35.

He would need 83 to get overall average to 83%.

He would need:

83 - 25.9 = 57.1 out of 65

That is:

Basically he would need a percentage of 87.85% (MINIMUM) on the final exam to make his overall average to 83% (which is the bare minimum for a B grade).

The farmer put a total of 47 potatoes in one sack.

Here, we are given that a farmer harvested 192 pounds of Yukon Gold potatoes and 138 pounds of russet potatoes.

He divided the Yukon Gold potatoes evenly among 8 baskets.

Thus, the number of pounds of potatoes in each basket = 192/8

= 24

Similarly, he divided the russet potatoes evenly among 6 baskets.

Thus, the number of pounds of  russet potatoes in each basket = 138/6

= 23

Now, he fills a sack with one basket of Yukon Gold potatoes and one basket of russet potatoes.

n = the number of pounds of potatoes the farmer put in the sack

Thus, n = 24 + 23

n = 47

Thus, the farmer put a total of 47 pounds of potatoes in one sack.

The first step to this problem is finding the amount of butterfat there are in the 385 gallons milk with 5% of butterfat in it. To do that we need to multiply the percentage by the total amount of milk. This is done below:

There are 19.25 gallons of butterfat on the final mixture, the amount of butterfat from each of the milks we are going to mix need to be equal to that. The first milk contains 8% of butterfat, while the second milk contains 1%. So we have:

Where "x" is the number of gallons from the first milk and "y" is the number of gallons from the second milk. The number of gallons of each milk, when added, should be equal to the number of gallons on the final milk, so we have:

The same is valid for the amount of butterfat.

We have now created a system of equations as shown below:

To solve this system we will multiply the first equation by "-0.01":

Now we need to add both equations.

To find the value of "y" we will use the first equation:

We need 220 gallons from the 8% butterfat milk and 165 gallons from the 1% butterfat milk.

The solution for this function will be x = -1 and x = 3

Quadratic polynomials are those with at least one variable and a variable with a maximum exponent of two. Since the second-degree term is the highest degree term in a quadratic function, it is sometimes referred to as the polynomial of degree 2. In a quadratic function, at least one term must be of the second degree. It has qualities in algebra.

The given function is -2x² + 4x + 6

So, we'll employ the middle term splitting strategy.

-2x² + 4x + 6 = 0

- 2x² + 6x - 2x + 6 = 0

-2x ( x-3) -2 (x-3) = 0

(-2x-2) (x-3) = 0

So, the solution will be

-2x - 2 = 0

-2x = 2

x = 2/-2

x = -1

And, x-3 =0

x = 3

So, the solution of the quadratic function will be

Answer:

Perimeter = 65.12 inches, Area = 292.48 square inches

Step-by-step explanation:

Perimeter:

Total perimeter = perimeter of semicircle + perimeter of rectangle (note: excluding the shared line, since that is not on the outside of the shape).

= [tex]\frac{1}{2} 2\pi r[/tex]

= [tex]\frac{1}{2} *2*3.14*8[/tex]

= 25.12

Perimeter = 25.12 + 12 + 12 + 16 = 65.12 inches

Area:
Total area = area of semicircle + area of rectangle

Area of semicircle = [tex]\frac{1}{2} \pi r^{2}[/tex]

= [tex]\frac{1}{2} *3.14* 8^{2}[/tex]

= 100.48

Area of rectangle = l * w

= 16 * 12

= 192

Total area = 100.48 + 192 = 292.48

x = 10 is the solution to the equation -8 - x = -3( 2x - 4 ) + 3x using DCMAM method.

Given the equation in the question;

First, apply the distributive property to eliminate the parenthesis.

-8 - x = -3( 2x - 4 ) + 3x

-8 - x = -3×2x -3×-4 + 3x

Multiply -3 × 2x

-8 - x = -6x -3×-4 + 3x

Multiply -3 × -4

-8 - x = -6x + 12 + 3x

Next, combine like terms.

Add -6x and 3x

-8 - x = -3x + 12

Next, move variable to one side and constant terms to the other.

-x + 3x =  12 + 8

Add -x and 3x

2x =  12 + 8

Add 12 and 8

2x = 20

Divide both sides by 2

2x/2 = 20/2

x = 20/2

x = 10

Therefore, the value of x is 10.

Answer:

y = -16 (x - 1)^2 + 112

The object lands on the ground in approximately 3.6s

Explanation:

The equation given is that of a parabola.

Now the maximum (local) point of a parabola is the vertex. Therefore, if we want to rewrite our function in the form that would be used to find the maximum height, then that form must be the vertex form of a parabola.

The vertex form of a parabola is

where (h, k) is the vertex.

The only question is, what is the vertex for our function h(t)?

Remember that if we have an equation of the form

then the x-coordinate of the vertex is

Now in our case b = 32 and a = -16; therefore,

We've found the value of the x-coordinate of the vertex. What about the y-coordinate? To get the y-coordinate, we put x = 1 into h(t) and get

Hence, the y-coordindate is k = 112.

Therefore, the vertex of the parabola is (1, 112).

With the coordinates of the vertex in hand, we now write the equation of the parabola in vertex form.

The only problem is that we don't know what the value of a is. How do we find a?

Note that the point (0, 96) lies on the parabola. In other words,

Therefore, the vertex form of the parabola must also contain the point (0, 96).

Putting in t = 0, h = 96 into the vertex form gives

subtracting 112 from both sides gives

With the value of a in hand, we can finally write the equation of the parabola on vertex form.

Now when does the object hit the ground? In other words, for what value of t is h(t) = 0? To find out we just have to solve the following for t.

We could either use h(t) = -16t^2 + 32t + 96 or the h(t) = -16(t - 1)^2 + 112 for the above equation. But it turns out, the vertex form is more convenient.

Thus we solve,

Now subtracting 112 from both sides gives

Dividing both sides by -16 gives

taking the square root of both sides gives

adding 1 to both sides gives

Hence, the two solutions we get are

Now since time cannot take a negative value, we discard the second solution and say that t = 3.6 is our valid solution.

Therefore, it takes about 3.6 seconds for the object to hit the ground.

It should be noted that a factor of a number is a number that can be multiplied with another number to get the original number.

In this case, 2x² + 7x - 6 will be factored thus:

= 2x² + 7x + 6

[tex]\begin{aligned}x=0 \implies -\dfrac{4(0+3)}{5} & \leq 4(0)-12\\\\ -\dfrac{4(3)}{5} & \leq 0-12\\\\ -\dfrac{12}{5} & \leq -12 \quad \Rightarrow \textsf{Not a solution}\end{aligned}[/tex]

The values of x < 2 are not solutions to the inequality.

--------------------------------------------------------------------------------

Substitute the value of x = 2 into the inequality:

[tex]\begin{aligned}x=0 \implies -\dfrac{4(2+3)}{5} & \leq 4(2)-12\\\\ -\dfrac{4(5)}{5} & \leq 8-12\\\\ -\dfrac{20}{5} & \leq -4\\\\ -4 & \leq -4 \quad \Rightarrow \textsf{Yes, a solution}\end{aligned}[/tex]

The value of x = 2 is a solution to the inequality.

--------------------------------------------------------------------------------

Values of x more than 2

Substitute two values where x > 2 into the inequality:

[tex]\begin{aligned}x=3 \implies -\dfrac{4(3+3)}{5} & \leq 4(3)-12\\\\ -\dfrac{4(6)}{5} & \leq 12-12\\\\ -\dfrac{24}{5} & \leq 0 \quad \Rightarrow \textsf{Yes, a solution}\end{aligned}[/tex]

[tex]\begin{aligned}x=4 \implies -\dfrac{4(4+3)}{5} & \leq 4(4)-12\\\\ -\dfrac{4(7)}{5} & \leq 16-12\\\\ -\dfrac{28}{5} & \leq 4 \quad \Rightarrow \textsf{Yes, a solution}\end{aligned}[/tex]

The values of x > 2 are solutions to the inequality.

--------------------------------------------------------------------------------

Therefore, the solution to the inequality appears to be x ≥ 2.  

To check, solve the inequality:

[tex]\begin{aligned} \implies -\dfrac{4(x+3)}{5} &\leq 4x-12\\-4(x+3) &\leq 5(4x-12)\\-4x-12 &\leq 20x-60\\ -24x & \leq-48\\x & \geq 2\end{aligned}[/tex]
