Answer:

the slope of the line is -3/4

Step-by-step explanation:

To find the slope of the line you can either use the formula y2-y2/x2-x1 and plugin 2 points on the line

so points (0,2) and (4,-1) would give you -1-2/4-0

simplified gives -3/4 for the slope.

The other way you could find the slope of the graph is to remember that slope is rise/run, this means that since your line is going down 3 numbers, the numerator (rise) would be -3, and it is going to the right 4 numbers, the denominator (run) would be 4. This would give you your slope of -3/4

Given: m∠p =47BD∥AC <br> What is the m∠m?<br><br> Put only the number. Do not label your answer.

Anettt [7]

Answer: $43\°$

Step-by-step explanation:

Observe the given figure.

You can identify that the measure of the angle "B" is:

$m\angle B=90\°$

Knowing this, you can conclude that the angle "p" and the angle "m" are Complementary angles, which means that the sum of their measures is 90 degrees. Then, you can write the following equation:

$m\angle p+m\angle m=90\°$ [Equation 1]

You know that:

$m\angle p=47\°$

Then you can substitute it into the [Equation 1] and then solve for $m\angle m$ . Therefore, you get:

$47\°+m\angle m=90\°\\\\m\angle m=90\°-47\°\\\\m\angle m=43\°$

A sound wave travels through iron at a rate of 5120\,\dfrac{\text{m}}{\text{s}}5120 s m 5120, start fraction, start text, m, e

Answer:

18432 km/h

Step-by-step explanation:

It is given that a sound wave travels through iron at a rate of 5120 m/s.

We know that

1 km = 1000 m

1 hour = 60 minutes

1 minutes = 60 second

Using these conversions we get

1 m = 0.001 km

1 hour = 3600 second

$5120\text{ m/s }=5120\times 0.001\times 3600\text{ km/h}$

$5120\text{ m/s }=18432\text{ km/h}$

Therefore, the sound wave travels through iron at a rate of 18432 km/h.

Answer is 36.
First use the negative exponent rule. When a number is put to the negative power it becomes a fraction
4/3^2

Now 3 to the second power is 9
4/1/9 (4 over 1/9)
Now multiply 4 x 9 (dividing by 1/9 is the same as multiplying by 9)

4 x 9= 36
