Answer:

  1 of 8: (729, 81, 9, 1)

  2 of 8: 1 = (-1)^0 = 2^0

  3 of 8: 1

Step-by-step explanation:

The basic rule is that any non-zero value to the zero power is 1. It doesn't matter whether the value is positive or negative. Raising it to the zero power makes it 1.

So, for question 2 of 8, the two equivalent expressions can be anything raised to the zero power (or anything with a value of 1, for that matter).

Step-by-step explanation:

3(a+3)+6=30

Subtract 6 from each side

3(a+3)+6-6=30-6

3(a+3) = 24

Divide by 3

3/3(a+3) = 24/3

a+3 = 8

Subtract 3 from each side

A)555 becuse 555/3=185

Answer:

Step-by-step explanation:

Please write points using parentheses:  (4, 5) and (-4, 8}.

​

(4, 5) is in the 1st quadrant and (-4, 8} is in the 2nd. Reversing the order of these two points yields (-4, 8) and (4, 5).  From this we can see that while moving from (-4, 8) to (4, 5) involves following a line with negative slope (because the y-coordinate decreases from 8 to 5 as the x-coordinate increases from -4 to +4).  This sloping line is the hypotenuse of a right triangle.  Draw a vertical line segment through (-4, 8) and a horizontal line segment through (4, 5).  This hypotenuse, the vertical line segment and the horizontal line segment are the boundaries of the desired right triangle.  

Answer:

19 ms

Step-by-step explanation:

We need to find the time it takes for the sound from the 6th row gets to the conductor.

Since there are 6 rows and each row is 3 feet apart, since the orchestra is arranged in a semi-circular manner around the conductor, the distance from the 6 th row to the 1st row is (6 - 1) × 3 = 5 × 3 = 15 feet.

Now, since the conductor is 6 feet from the first row, his distance from the 6th row is 15 feet + 6 feet = 21 feet.

So, time approximate delay between the instant when a play at the 6th row start a note and when the conductor hears the note, t = distance between 6th row and conductor/speed of sound.

Speed of sound = 343 m/s

distance between 6th row and conductor = 21 feet. In meters, it is 21 × 0.3048 m = 6.4008 m

t = 6.4008 m ÷ 343 m/s

= 0.019 s

= 19 ms

Step-by-step explanation:

10:12 and 30:36

you can simplify them first so

10:12=5:6

and

30:36=5:6 which is equivalent to the other ratio

or you can do

Answer:

y = x - 3

Step-by-step explanation:

Answer:

Y= x-3

Step-by-step explanation:

The distance from our y values is -1.

The distance from our x values is -1.

Rise/ Run = Y/X

-1/-1 = 1 or 1/1

You would rise 1 and run 1!

You can use this strategy if you're using graph paper to eventually get the y intercept which is -3.

Hope this helps! :)

Answer: m = 3/2, b = -5

Step-by-step explanation:

When we input these values into slope-intercept form y = mx + b, then we get y = 3/2x -5. When trying out different x values, we get the same points that are on the line such as (2, -2) also the y-intercept is -5, so we know it is a true statement and that the slope 3/2 and y-intercept -5 are the only correct answers for this line.

Answer:

25/52, bcos there are 25 odd numbers from 1 to 52

Answer:

b. x - 2y = 4

Step-by-step explanation:

The two points on the graph are (0, -2) and (4, 0).

Find slope:

m = (y₂ - y₁) / (x₂ - x₁)

  = (0 - (-2)) / (4 - 0)

  = 2 / 4

  = 1 / 2

Find y intercept using anyone of the points above:

y = mx + b

-2 = 1/2(0) + b

b = -2

Use m and b to make equation of line:

y = mx + b

y = 1/2x - 2

Possible answers:

a. 4x - 2y = 4

         -2y = -4x + 4

             y = 2x - 2

b. x - 2y = 4

       -2y = -x + 4

           y = 1/2x - 2

c. -2x + 4y = -4

            4y = + 2x - 4

              y = 1/2x - 1

Only choice b equals the equation of line above.

Answer:

ex:Speed (S) is the ratio of the distance (D) covered to the time (t) taken.

That is, S = D/t

Suppose Andrew ran a distance D1 in 1 hour (3600 seconds) at a Speed, say S1, we have

S1 = D1/t

We can then say he ran a distance

D1 = t × S1

= 3600S1

Similarly, let's say Karleigh ran a distance

D2 = t × S2

= 3600S2

Let us compare these two, you will notice that the bigger number between S1 and S2 is going to determine the bigger number between D1 and D2.

Let's choose random numbers for S1 and S2 for clarity, say S1 = 5, S2 = 10

D1 = 3600 × 5

= 18000

D2 = 3600 × 10

= 36000

This makes D2 bigger than D1. this is an example i found on the internet.

The ratio of the change in distance to the corresponding change in time

gives the speed of a runner.

Reasons:

The tables are;

Andrew

Karleigh

[tex]\begin{tabular}{|cc|c|}Time in Minutes&&Distance in miles\\30&&3\\40&&4\end{array}\right][/tex]

The duration each on the treadmills is 1 hour = 60 minutes

[tex]\displaystyle Speed = \mathbf{\frac{Change \ in \ distance}{Change \ in \ time}}[/tex]

Therefore;

[tex]\displaystyle Andrew's \ speed = \frac{2 \, miles - 1.5 \, miles}{24 \, minutes - 18\, minutes} = \mathbf{\frac{1}{12} \ mile/minute}[/tex]

[tex]\displaystyle The \ distance \ Andrew \ ran = \frac{1}{12} \ miles/min \times 60 \ min = \mathbf{5 \ miles}[/tex]

[tex]\displaystyle Karleigh's \ speed = \frac{4 \, miles - 3 \, miles}{40 \, minutes - 30 \, minutes} = \mathbf{\frac{1}{10} \, mile/minute}[/tex]

[tex]\displaystyle The \ distance \ Karleigh \ ran = \frac{1}{10} \, miles/min \times 60 \ min = \mathbf{6 \ miles}[/tex]

Step-by-step explanation:

Answer: 2 hrs 40 min

Step-by-step explanation:  Ok I might be wrong so try to do other people's answers instead of mine.

So your friend is going 6 miles per hour, so he/she will be there in an hour

But you are going 3.5 miles an hour.

So what I did was divide 3.5 by 5 and 60 by 5 and found out that you are going 0.5 miles every 20 min. Then I added up the distance and time and got 6 miles every 2 hrs and 40 min
