The governing equation is z = k/x.

When x=3, z = 1 2/3, or z = 5/3. Find k: 5/3 = k/3. Then k = 5, and the

governing equation becomes z = 5/x.

Now if x=12,

z = 5/12 (answer)

What is the volume of the figure?
serious [3.7K]

Answer:

188 ft^{3}

Step-by-step explanation:

So we can split up this shape into two prisms and then add the two areas.

The volume of a rectangular prism is V = l*w*h

For the first prism, we have our length as 3, our width as 4, and our height as 9. Substituting these values into our volume equation gives us V = (3)(4)(9) = 108 ft^{3}.

Now for the second prism, we have our length as 5, our width as 4, and our height as 4. Substituting these values into our volume equation give us V = (5)(4)(4) = 80 ft^{3}

Now adding these two values will give us the area of the entire figure: 108ft^{3} +80ft^{3} = 188 ft^{3}

<h3>Answer: 10.1 cm approximately</h3>

=====================================================

Explanation:

The double tickmarks show that segments DE and EB are the same length.

The diagram shows that DB = 16 cm long

We'll use these facts to find DE

DE+EB = DB

DE+DE = DB

2*DE = DB

DE = DB/2

DE = 16/2

DE = 8

-------------

Now let's focus on triangle DEC. We just found the horizontal leg is 8 units long. The vertical leg is EC which is unknown for now. We'll call it x. The hypotenuse is CD = 9

Use the pythagorean theorem to find x

a^2+b^2 = c^2

8^2+x^2 = 9^2

64+x^2 = 81

x^2 = 81 - 64

x^2 = 17

x = sqrt(17)

That makes EC to be exactly sqrt(17) units long.

If you follow those same steps for triangle ADE, then you'll find the missing length is AE = 6

---------------

So,

AC = AE+EC

AC = 6 + sqrt(17)

AC = 10.1231056256177

AC = 10.1 cm approximately

A VW Bug is driving north on a straight two-lane road at a constant 38 mph and a Chevy Impala is driving south at 29 mph on the
vitfil [10]

Those two vehicles are chewing up a lot of ground. Do you drive? I know it's a stupid question. Every American drives, but I have to check. When you see a car coming towards you, does it look like it's going extremely slow, so that 9 could be the answer? Or does it look extremely fast so that 67 could be the answer? I think you should be looking at fast. I live in the country so when something comes towards me I take note of it. So you should be thinking the Impala sees the bug as going north and very fast..

B

Note. The 9 would come up when someone was passing you and they were going 9 mph faster than you were going. If you were going 50 mph and someone passed you at 59 mph. it would appear to you that they were only going 9 mph. Next time you encounter this on the road, see if you agree that that is the way it works.
