4. How long would it take sound waves traveling through air that is 68°F to
travel 1,372 meters? Use an equation to solve the problem.

Answers

Answer 1

Answer:

2.7 seconds

Step-by-step explanation:

[] Temp of air: 68°F -> 20°C

[] Velocity of sound in air:

[tex]v=331.3\sqrt{1+\frac{T}{273.15} }[/tex]

[tex]v=331.3\sqrt{1+\frac{68}{273.15} }[/tex]

v ≈ 370.25 m/s

[] Last,

t = [tex]\frac{d}{v}[/tex]

t = [tex]\frac{1,372}{370.25}[/tex]

t ≈ 3.7056 ≈ 2.7 seconds

Step-by-step explanation:

The measure of a triangle is 180.  

Make all the angles equal 180.

50+80+6x-4=180.

Solve.

6x=54

x=9

Answer:

9

Step-by-step explanation:

All triangle angles add up to 180 degrees.

50 + 80 + (6x - 4) = 180

130 + (6x - 4) = 180

-130                  -130

6x - 4 = 50

6.4/7.2 he inverted the fraction which is wrong

you can only invert the fraction when the power is negative

The image of the point (4, -9) under a translation is (9, -14). Find the coordinates
of the image of the point (-9, -8) under the same translation.

Answers

9514 1404 393

Answer:

  (-4, -13)

Step-by-step explanation:

When the translation (T) is added, the image is formed.

  (4, -9) +T = (9, -14)

  T = (9, -14) -(4, -9) = (9-4, -14-(-9)) = (5, -5)

The same holds for the second point:

  (-9, -8) +T = (-9, -8) +(5, -5) = (-9 +5, -8 -5) = (-4, -13)

The image of the second point under the same translation is (-4, -13).

Which table represents a linear function?

Answers

The table that represents a linear function, having a slope value of 2 is: Table 4 (see image attached below)

Recall:

A function that is linear has a dependent and independent variable, such that y = mx + b.The "m" represents the slope which is the same all through the points given.m = change in y / change in x

Thus, the fourth table has the following slope (m) that is the same across all points.

Using two pairs of points, (0, 1) and (1, 3):

Slope = 3 - 1/1 - 0 = 2/1

Slope (m) = 2

Any two pairs of points we use will give us the same slope (m) of 2.

Table 1, 2 and 3 will give us different slopes across the points on each table, meaning they do not represent a linear function.

Therefore, the table that represents a linear function, having a slope value of 2 is: Table 4 (see image attached below).

Answers

The amount of edging trim needed will be equal to the circumference of the given circle, so it will be 31.4ft

We know that the circumference of a circle of diameter D is given by:

C = 3.14*D

Here, we have a circular garden with a diameter of 10ft, and we want to place edging trim along its circumference, so the amount of edging trim that we need is given by:

C = 3.14*10ft = 31.4 ft

You need 31.4ft of edging trim to surround the garden by placing the trim all along the garden's circumference.
