Answer:

The answer is 76.

Step-by-step explanation:

≅ means to be equal to.

☆Angle DGE ≅ EGF.

Therefore, 3x + 8 = 5x - 12

☆Let's solve that equation.

[tex]3x + 8 = 5x - 12 \\ \frac{ - 5x \: \: \: \: \: \: \: = - 5x \: \: \: \: \: \: \: \: }{ - 2x + 8 = - 12} \\ \frac{ \: \: \: \: \: \: \: \: - 8 = - 8}{ \frac{ - 2x}{ - 2} = \frac{ - 20}{ - 2} } \\ x = 10[/tex]

We found the value of x which is 10.

☆Let's Now plug in.

[tex]DGE \\ 3x + 8 \\ 3(10) + 8 \\ 30 + 8 \\ 38[/tex]

and the other:

[tex]EGF \\ 5x - 12 \\ 5(10) - 12 \\ 50 - 12 \\ 38[/tex]

☆They asked for what the angle of DGF measured. So we would have to add both sides

[tex]38 + 38 = 76[/tex]

☆The answer is 76

In problem 1, the x-coefficients are 8 and 2. A common factor of 2 can be removed so that we're dealing with the numbers 4 and 1. Assuming we want to multiply one of the equations by 1, leaving it unchanged, the value we want to multiply by will be -4. After we swap the coefficients, that multiplier is associated with equation 2:

  multiply equation 2 by -4 . . . (eliminates x)

Likewise, the y-coefficients in problem 1 are -1 and 3. Again, if we want to multiply one of the equations by 1, leaving it unchanged, the coefficient we will change the sign of is -1 (becomes 1). After we swap the coefficients, the multiplier 3 is associated with equation 1:

  multiply equation 1 by 3 . . . (eliminates y)

These two choices are B and A, respectively, so the one that does NOT work for problem 1 is choice C, as indicated below.

Answer:

[tex]x = 39\frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]Total\ Distance = 124\ miles[/tex]

[tex]First\ hour = 45\frac{1}{2}[/tex]

Required

Determine the distance covered in the last hour

Since the distance in the last 2 hours are the same. Represent the distance in each of the remaining hours as x.

So:

[tex]First\ Hour + Second\ Hour + Third\ Hour = Total[/tex]

[tex]45\frac{1}{2} + x + x = 124[/tex]

[tex]45\frac{1}{2} + 2x = 124[/tex]

Collect Like Terms

[tex]2x = 124 - 45\frac{1}{2}[/tex]

[tex]2x = 124 - \frac{91}{2}[/tex]

Take LCK

[tex]2x = \frac{248-91}{2}[/tex]

[tex]2x = \frac{157}{2}[/tex]

Divide both sides by 2

[tex]x = \frac{157}{2} * \frac{1}{2}[/tex]

[tex]x = \frac{157}{4}[/tex]

[tex]x = 39\frac{1}{4}[/tex]

Hence, the distance in the third lap is: [tex]x = 39\frac{1}{4}[/tex]

Answer: b) angle OPN and angle TSU

=========================================================

Explanation:

Each answer choice involves angle OPN, so the other angle must be based off this. The other angle is TSU because these two angles are on alternating sides of the transversal line UN.

Angle OPN and angle TSU are also exterior angles because they are on the outside region of the parallel lines OQ and RT.

So combine the two concepts and we can say that angles OPN and TSU are alternate exterior angles. The other alternate exterior angle pair is angle USR and angle NPQ.

Due to the parallel lines, the alternate exterior angles are congruent.

Answer:

y = -2000x+30000

Step-by-step explanation:

Hi. So, you are just setting up a linear equation using slope intercept data. The slope being -2000 (because it is descending) and the intercept being 30,000 at t=0.

y = -2000x+30000

Answer:

Marcus is wrong.

Step-by-step explanation:

As we see from the figure the angles ORP and PRM makes 180 degrees or are supplementary angles.

Marcus is wrong because a linear pair has a sum equal to 180 degrees.

But if we observe carefully the angles ORP and LRP don not together make an angle of 180 degrees. Also these angles do not have opposite rays .

Therefore angles PRM and ORP are linear pair angles but angle ORP and angle LRP are not a linear pair.

These angles do not have opposite arms as uncommon sides .

The linear pair must have

1) 180 degrees

2) opposite rays as uncommon sides

3) common vertex

Answer:

He is incorrect. Ray RO and ray RL are not opposite rays.

Step-by-step explanation:

Marcus is incorrect. In order for angles to be a linear pair, the rays of the angles that don't have a common side point, need to be opposite. This is not true for rays RO and RL, so Marcus's statement is not true.

Answer:

Step-by-step explanation

∠MJH = 180 - 145

           = 35°

Assuming the two angles form a straight line then the measure of the other angle is 35°

Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50 is equal to 180°

Given here, m∠HJM = 145° then m∠MHJ = 180° - 145°

                                                                   = 35°

Hence the measure of the angle is 35°

Answer:

To get a function of degree 5, either functions of degree 1 and 4 or functions of degree 2 and 3 should be multiplied.

This function will have a total of 5 zeros, same as its degree.

The function of degree 5 will have at least one and up to five real zeros

The rest of the zero's are imaginary.

So if has 2 real zeros, then the remaining 3 will be imaginary.

Maximum number of imaginary zero's is 4.

Answer:

The percentage of school time missed by the average student during 2009/2010 school year in Detroit is 23.08%.

Step-by-step explanation:

The percentage of school time missed by the average student during 2009/2010 school year in Detroit can be calculated as follows:

Percentage of school time missed = (Average number weeks of school missed / Total number of weeks in a school year) * 100 ................... (1)

Where;

Average number weeks of school missed = 9

Total number of weeks in a school year = 39

Substituting the values into equation (1), we have:

Percentage of school time missed = (9 / 39) * 100

Percentage of school time missed = 0.230769230769231 * 100

Percentage of school time missed = 23.0769230769231%

Rounding to 2 decimal places, we have:

Percentage of school time missed = 23.08%

Therefore, the percentage of school time missed by the average student during 2009/2010 school year in Detroit is 23.08%.

Answer:

Option A is correct.

Step-by-step explanation:

Given

To determine

What is the equation in the standard form of the line that passes through the point (4, −8) and has a slope of 1/4.

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

substituting the values m = 1/4 and the point (4, -8)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-8\right)=\frac{1}{4}\left(x-4\right)[/tex]

[tex]y+8=\frac{1}{4}\left(x-4\right)[/tex]

Subtract 8 from both sides

[tex]y+8-8=\frac{1}{4}\left(x-4\right)-8[/tex]

[tex]y=\frac{1}{4}x-1-8[/tex]

[tex]y=\frac{1}{4}x-9[/tex]

Writing the equation in the standard form

As we know that the equation in the standard form is

Ax+By=C

where x and y are variables and A, B and C are constants

so

[tex]y=\frac{1}{4}x-9[/tex]

[tex]x=4y+36[/tex]

[tex]x - 4y = 36[/tex]

Therefore, the equation in the standard form of the line that passes through the point (4, −8) and has a slope of 1/4 will be:

[tex]x - 4y = 36[/tex]

Hence, option A is correct.
