balu736 [363]

a) The fire burnt 840.6 square miles

b) The fire burnt 16.8 tempe

Step-by-step explanation:

1 square mile = 640 acres

a) to find how many square miles did the fire burn:

Total area the fire burn = 538000 acres

1 square miles = 640 acres

Concert the acres into square miles

538000/ 640 = 840.6 square miles

The fire burnt 840.6 square miles

b) 50 square miles= 1 temperatures

The no. Of tempe the fire burn = 840.6/50

= 16.8 tempe

The fire burnt 16.8 tempe

Answer:

square root of 2 or if needed simplified, 1.414213 to the nearest millionth.

Step-by-step explanation:

Start with the equation d= square root of (11-10)^2+(4-5)^2 where that is simplified to square root of (1)^2+(-1)^2 to square root of 1+1 to your final answer, square root of 2. Also simplified to 1.414213.

What is the volume of a sphere with a radius of 12 units?

\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

\sf{Formula \ for \ Volume \ of \ a \ sphere \ : \bigstar\boxed{\bold{V=\displaystyle\frac{4}{3} \pi r^3}}

Where

\tt{V=Volume}\\\tt{\pi =pi}\\\tt{r=radius}

Provided Information:-

\tt{r=12\:units}

Plug in:-

\bold{V=\displaystyle\frac{4}{3} \pi (12)^3}

\bold{V=\displaystyle\frac{4}{3} \pi (1,728)}

On further simplification,

\dashrightarrow\boxed{\boxed{\underline{\bold{V=2304\pi\:m^3}}}}\dashleftarrow

What is the equation of a line that passes through (0.8) and (3,6)?
nirvana33 [79]

Answer:

y=\frac{-2}{3}x+8

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: y=mx+b where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

<u>1) Determine the slope (m)</u>

m=\frac{y_2-y_1}{x_2-x_1} where the given points (x_1,y_1) are (x_2,y_2)

Plug in the given points (0,8) and (3,6)

m=\frac{6-8}{3-0}\\m=\frac{-2}{3}

Therefore the slope of the line is \frac{-2}{3}. Plug this into y=mx+b:

y=\frac{-2}{3}x+b

<u>2) Determine the y-intercept (b)</u>

y=\frac{-2}{3}x+b

The y-intercept occurs when x=0. One of the given points is (0,8), so therefore, the y-intercept is 8. Plug this into y=\frac{-2}{3}x+b:

y=\frac{-2}{3}x+8

I hope this helps!
