Eduardo counted ten seconds (y) between seeing lightning and hearing thunder, and he knew that the lightning was about 2 miles (

x) away. What is the equation of the variation?
Mathematics
1 answer:
Fed [463]3 years ago
5 0

Answer:

The equation for the variation is:

\frac{Miles}{thunder\,\,time }  =0.2\,\frac{mi}{s}

Step-by-step explanation:

The relationship is given by the quotient between the two variables: (1) distance of the storm, and (2) the number of seconds to hear the thunder. That is:

\frac{Miles}{thunder\,\,time } =\frac{2}{10} =0.2\,\frac{mi}{s}

Is anyone good at math and can help with this, or at least the first one and explain how to do it?​
Anna007 [38]

now, bear in mind that all these ones are lines, and to graph a line all you need is two points, so let's pick a couple of random values for say "x" and let's see what we get for "y" and that's our x,y point.

3)

9x+4y=-16\implies \stackrel{\textit{using x = 0}~\hfill }{9(0)+4y=-16}\implies 4y=-16 \\\\\\ y=\cfrac{-16}{4}\implies y=-4~\hspace{10em}(0~~,~~-4) \\\\[-0.35em] ~\dotfill\\\\ 9x+4y=-16\implies \stackrel{\textit{using x = -4}~\hfill }{9(-4)+4y=-16}\implies -36+4y=-16 \\\\\\ 4y=20\implies y = \cfrac{20}{4}\implies y = 5~\hspace{10em}(-4~~,~~5)

check the red line in the picture below.

4)

5x+2y=8\implies \stackrel{\textit{using x = 0}~\hfill }{5(0)+2y=8}\implies 2y=8\implies y=\cfrac{8}{2}\implies y=4 \\\\\\ ~\hspace{10em}~\hspace{10em}(0~~,~~4) \\\\\\ 5x+2y=8\implies \stackrel{\textit{using x = 4}~\hfill }{5(4)+2y=8}\implies 20+2y=8\implies 2y=-12 \\\\\\ y=\cfrac{-12}{2}\implies y=-6~\hspace{10em}(4~~,~~-6)

check the blue line in the picture below.

Please awnser question from image down below
Natalija [7]

Answer:

C 10 in

Step-by-step explanation:

side of P is \sqrt{36} = 6

side of Q is \sqrt{64} = 8

for missing side use Pythagorean theorem

r^{2} = 6^{2}  + 8^{2}

r^{2} = 36 + 64

r^{2} = 100

r = 10 in

A prism is filled with 28 cubes with 1/2 unit lengths. What is the volume of the prism in cubic units?
stira [4]

Answer:

3.5 cubic units

Step-by-step explanation:

First, find the volume of one cube

Use the cube volume formula, V = s³, where s is the side length

V = (1/2)³

V = 1/8 cubic units

Now, find the volume of the prism by multiplying this by 28, since there are 28 cubes

28(1/8)

= 3.5

So, the volume of the prism is 3.5 cubic units
