5 hours and 20 minutes because 1/3 as a decimal is 0.3 continued (i wrote down 0.33 so its simplified) and 0.33 decimal hours is 20 minutes.

The veloctiy of sound in air is given by the equation v=20 times the square root of 273+t where v is the velocity in meters per
Nikitich [7]
So we just need to plug in our values and solve
v = 20 \sqrt{273 + t}
we are given v is 369 so we have
369 = 20 \sqrt{273 + x}
now we solve for x.
divide both sides by 20
square both sides
subtract 273 from both sides
369 = 20 \sqrt{273 + x}  \\ 18.45 =  \sqrt{273 + x}  \\ 340.40 = 273 + x \\ x = 67.4
so a temp of about 67 degrees C

What are the steps to solving <br> 3x=4+2(3−x).
masya89 [10]

Answer:

x = 2

Step-by-step explanation:

How to find "x"

3x = 4 + 2(3 - x) *Remove the parentheses*

3x = 4 + 6 - 2x *Calculate*

3x = 10 - 2x *Move the variable to the left*

3x + 2x = 10 *Collect the terms*

5x = 10 *Divide both sides*

x = 2

I hope the helped!!!

True or False: The value of r represents the reference angle when plotting a point in polar coordinates.
Anarel [89]
The answer to the statement above would be false. The value of r does not represent the reference angle when plotting a point in polar coordinates. Instead, it represents the polar distance instead of the angle. The reference angle is represented by <em>t.</em>

HELP PRETTY PLEASE THIS IS URGENT NEED IN THE NEXT HOUR!!
zmey [24]

Answer:

(- 2, 6 )

Step-by-step explanation:

Given the equations

3x + 2y = 6 → (1)

\frac{2}{3} y - x = 6 ( multiply through by 3 to clear the fraction )

2y - 3x = 18 ( add 3x to both sides )

2y = 18 + 3x → (2)

Substitute 2y = 18 + 3x into (1)

3x + 18 + 3x = 6

6x + 18 = 6 ( subtract 18 from both sides )

6x = - 12 ( divide both sides by 6 )

x = - 2

Substitute x = - 2 into (1) and solve for y

3(- 2) + 2y = 6

- 6 + 2y = 6 ( add 6 to both sides )

2y = 12 ( divide both sides by 2 )

y = 6

solution is (- 2, 6 )
