Average speed =  total distances / total time

3115.8 / 7.2 = 432.75 mi/h

Formula for speed = Distance/Time

Now that we know that, the distance the plane flew is 3115.8 miles and the time was 7.2 hours

So we arrange it like this: 

3115.8 / 7.2

Now if we use a calculator, your answer should be...

432.75 mph

Find the volume of the figure
mina [271]

Answer:

It is C. 233 because if you multiply 5x5x5 thats 125

If you multiply 12x3x3, its 108. So add 108+125 and that will be your final answer. Hope this helps and if so then please mark as brainliest. Remember that volume= length x width x height.

Which is the approximate solution for the system of equations 3x+4y=2 and 4x+y=-4
harina [27]

3x+4y=2\qquad\text{subtract 3x from both sides}\\\\4y=-3x+2\qquad\text{divide both sides by 4}\\\\y=-\dfrac{3}{4}x+\dfrac{2}{4}\to y=-\dfrac{3}{4}x+\dfrac{1}{2}\\\\for\ x=0\to y=-\dfrac{3}{4}(0)+\dfrac{1}{2}=0+\dfrac{1}{2}=\dfrac{1}{2}\to\left(0,\ \dfrac{1}{2}\right)\\\\for\ x=2\to y=-\dfrac{3}{4}(2)+\dfrac{1}{2}=-\dfrac{3}{2}+\dfrac{1}{2}=-\dfrac{2}{2}=-1\to(2,\ -1)\\--------------------------------\\

4x+y=-4\qquad\text{subtract 4x from both sides}\\\\y=-4x-4\\\\for\ x=0\to y=-4(0)-4=0-4=-4\to(0,\ -4)\\\\for\ x=-1\to y=-4(-1)-4=4-4=0\to(-1,\ 0)\\\\Answer:\ \boxed{A.\ (-1.4,\ 1.5)}

Juanita and lauren are painting a circular mural on one wall of the community center. The area of the mural is 33 square meters
tangare [24]

Answer:

The radius is 3.24102 meters

Step-by-step explanation:

We are given

area of mural is 33 m^2

Since, the shape of mural is circular

Let's assume radius of circle as 'r'

so, we can use area of circle formula

A=\pi r^2

now, we can set A=33

and then we can solve for r

33=\pi r^2

we get

r^2=\frac{33}{\pi }

r=3.24102

So,

The radius is 3.24102 meters
