Answer:

  x = 3

Step-by-step explanation:

You can forget about point R. It does not have any part in this problem, except to add confusion.

The given line PQ has the same y-coordinate values for points P and Q. This means the segment is a horizontal segment. Its perpendicular bisector will be a vertical line through its midpoint.

The midpoint (M) of PQ is ...

  M = (P +Q)/2

  M = ((-2, 2) +(8, 2))/2 = (-2+8, 2+2)/2 = (6, 4)/2

  M = (3, 2)

The vertical line through a point with x-coordinate 3 will have the equation ...

  x = 3

Answer:

3 miles per hour

Step-by-step explanation:

Well, what we do in these situations is simple. We divide.

So this George guy, he walks six miles in 2 hours.

I think to myself, "Okay, so that's 6 divided by 2."

So, we get 3.

#It'sNotRocketScience

if George walked 6 miles in 2 hours. Then his average walking rate in miles per hour is 3 miles per hour

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

George walked 6 miles in 2 hours.

We need to find his average walking rate in miles per hour

Let x be the average walking rate in miles per hour

Let us form an equation

miles/hour----->6/2=x/1

3=x

So the value of x is 3

Hence if George walked 6 miles in 2 hours. Then his average walking rate in miles per hour is 3 miles per hour

Answer:

Step-by-step explanation:

Based on the balance on her account on October 25th, we can calculate that her balance on October 26th was a. $112.16

Any expenses that we make from our bank account reduces our bank balance. This means that Maggie's buying of gasoline and the dinner she went on will reduce her account balance.

Her new balance will therefore be:

= Beginning amount - Expenses

= 170.29 - 32.51 - 25.62

= $112.16

In conclusion, her balance on October 26th is $112.16

$9,800.07

Step-by-step explanation:

Just took a quiz.

There will be $9,800.07  after 4 years if Barbara wants to restore her '66 Mustang in 4 years. She puts $200 into an account every month that pays 1.05% interest,

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]

[tex]\rm A = P(1+\dfrac{r}{n})^{nt}+\dfrac{PMD((1+\dfrac{r}{n})^{nt}-1)}{\dfrac{r}{n}}[/tex]

Where A = Final amount

          P = Principal amount

          r  = annual rate of interest

          n = how many times interest is compounded per year

          t = How long the money is deposited or borrowed (in years)

PMD = $200

r/n = 0.0105/12

n = 12

t = 4 years

After plugging the all values in the formula, we will get:

A = $9,800.07

Thus, there will be $9,800.07  after 4 years if Barbara wants to restore her '66 Mustang in 4 years. She puts $200 into an account every month that pays 1.05% interest,

Answer:Music in a major key can be transposed to any other major key; music in a minor key can be transposed to any other minor key. (Changing a piece from minor to major or vice-versa requires many more changes than simple transposition.) A piece will also sound higher or lower once it is transposed.

Step-by-step explanation:

Well you can elimate a lot of fractions right off the bat just multiply everything by 60/1.

the final result will be

(240+15+40)+ (300+90-72)- (360+105+24)

Now solve

240-15+40=265

300+90-72=318

360+105+24=513

265+268-489

49 = 7x7, right?

and

7 = 7 x 1

then (49x + 7y) = (7*7x + 7y) = 7(7x + 1y)

7*7x = 49x

7*1y = 7y

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

1*7 -----> 7(7x + 1y)

Using the information given above, the sampling distribution of the sample proportion of 100-ohm gold-band is 2.

The sampling distribution of the sample proportion can be calculated thus:

Distribution of sample proportion = (100 × 0.02) = 2

Therefore, there is a probability that only 2 of the samples will have resistances exceeding 105 ohms.

Answer: y=1/4x+4

Step-by-step explanation:

Parallel means the new equation will have the same slope.

y= 1/4x+b

We don't know the b value yet but we can plug in coordinates to solve. We can use the one provided since it has to be a value of this equation.

1= 1/4(-12)+b

1= -3+b

b= 4

y=1/4x+4
