Answer:

1/2+1/4

4/8+2/8

6/8

3/4

Step-by-step explanation:

Answer:

The answer is 3/4.

Step-by-step explanation:

1/2+1/4

First we want to get a common denominator so that they can be added together.

1/2 * 2/2 = 2/4

We multiplied 1/2 by 2/2 so that both terms have a denominator of 4. Note that we also multiplied the top and bottom of 1/2 because we have to keep the value of the fraction the same.

Now we just add the fractions together.

2/4 + 1/4 = 3/4

So 3/4 is the answer. It is already in its simplest form meaning it cannot be simplified further.

Answer:

123 degrees

Step-by-step explanation:

Angles in a quadrilateral add up to 360 degrees

so we add all the angles

114 + 80 + 43 which is 237

360 - 237 is 123

so angle x is 123 degrees

Answer:

1750 calories

Step-by-step explanation:

2000 on average

1750 for his diet

2000 x 7 = 14,000

1750 x 7 = 12,250

14,000 - 12,250 = 1750

Answer: A

Step-by-step explanation:

The proof that is not needed John's proof is When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent

The following proof are needed.

m∠4 + m∠2 + m∠5 = 180° (sum of angles on  a straight line)

∠4≅∠1  and ∠5≅∠3 (alternate interior angles)

Therefore,

∠1  can replace ∠4 and ∠3 can replace ∠5

m∠1 + m∠2 + m∠3 = 180°

Therefore, When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent is not needed.

Answer:

140, 60

Step-by-step explanation:

15x+5 + < CDB =180 line form an 180 angle

180-80-6x-6 = < CDB sum of angles in a triangle is 180

substitute < CDB from second to first

15x+5+180 -80-6x-6 =180

combine like terms

9x -81 =0

x=81/9=9

so angle YDC = 15*9+5 = 140 degrees

and angle DBC = 6*9+6= 60 degrees

Answer:

9

Step-by-step explanation:

It is very simple, 3/4 * 2 = 1.5

If we take 1.5 and multiply it by the amount of batches being made (6), we will have our answer.

1.5*6 = 9, so there we have our answer.

Answer:

The average time to commute to work is 25 minutes.

Step-by-step explanation:

If average time for Dora to commute to work is 5 mins. If she takes 45 mins to get to work then her overall average time to commute to work will change as the average consists of 2 or more figures. The average time to commute to work is 25 mins ((5+45)/2). The average of 5 mins and 45 mins is 25 mins. This is the overall average time she takes to commute to her work.

Answer:

[tex]\displaystyle h=-\frac{1}{6}x^2+2x[/tex]

Step-by-step explanation:

We are given that the height of the tunnel is modeled by:

[tex]h=rx^2+tx[/tex]

Where r and t are constants.

We are also given that the maximum height of the tunnel h is six meters.

And at ground level, the width is 12 meters.

And we want to determine the equation of the parabola.

First, since this is a quadratic, our maximum height h will occur at the vertex of our equation.

Recall that the vertex is given by the formulas:

[tex]\displaystyle \text{Vertex} = \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]

In our case, we have the function:

[tex]h=(r)x^2+(t)x[/tex]

Hence, a = r; b = t; and c = 0.

Therefore, the x-coordinate of our vertex is:

[tex]\displaystyle x = -\frac{t}{2r}[/tex]

Therefore, if we substitute this back into our equation, the result should be six since six is the maximum height. Hence:

[tex]\displaystyle (6)=r\left(-\frac{t}{2r}\right)^2+t\left(-\frac{t}{2r}\right)[/tex]

Simplify:

[tex]\displaystyle 6=r\left(\frac{t^2}{4r^2}\right)-\frac{t^2}{2r}[/tex]

Simplify:

[tex]\displaystyle 6=\frac{t^2}{4r}-\frac{t^2}{2r}[/tex]

Subtract:

[tex]\displaystyle 6=\frac{t^2}{4r}-\frac{2t^2}{4r} = -\frac{t^2}{4r}[/tex]

Multiply:

[tex]\displaystyle 24r=-t^2, \, r\neq 0[/tex]

Solve for r:

[tex]\displaystyle r=-\frac{t^2}{24}[/tex]

Next, we are given that the width is 12 meters at ground level.

Hence, when h = 0, the difference of our roots is 12:

We have:

[tex]0=rx^2+tx[/tex]

Factor:

[tex]0=x(rx+t)[/tex]

By the Zero Product Property:

[tex]x=0\text{ or } rx+t=0[/tex]

Hence, the first zero is 0.

Therefore, the second zero must be 12 to ensure that our width is 12.

Let's isolate the second zero. Subtract t from both sides:

[tex]rx=-t[/tex]

Divide both sides by r:

[tex]\displaystyle x=-\frac{t}{r}[/tex]

We know that this zero must be 12. Thus:

[tex]\displaystyle 12=-\frac{t}{r}[/tex]

We have previously solved for r. Substitute:

[tex]\displaystyle 12=-\frac{t}{-\dfrac{t^2}{24}}[/tex]

Simplify:

[tex]\displaystyle 12=\frac{24}{t}[/tex]

Take the reciprocal of both sides:

[tex]\displaystyle \frac{t}{24}=\frac{1}{12}[/tex]

Multiply. Hence, the value of t is:

[tex]t=2[/tex]

Find r. Recall that:

[tex]\displaystyle r=-\frac{t^2}{24}[/tex]

Therefore:

[tex]\displaystyle r=-\frac{(2)^2}{24}=-\frac{4}{24}=-\frac{1}{6}[/tex]

Then in conclusion, our equation will be:

[tex]\displaystyle h=-\frac{1}{6}x^2+2x[/tex]

Answer:

A

Step-by-step explanation:

-4x-10≤2

-4x≤12 Add 10 on both sides

-x≤3 Divide by 4 on both sides

x≤-3 put a negative on both sides
