Answer:

a. For x=0.5→  y=36

b. For x=1→  y=18

c. For x=2→  y=9

d. For x=3→  y=6

Step-by-step explanation:

Since the  variables "x" and "y" are inversely related, the equation has the following form:

y=\frac{k}{x}

Where "k" is the constant of variation.

In this case we know that:

k=18

So, the equation is:

y=\frac{18}{x}

Therefore, substituting the given values of "x" into the equation, we get:

a. For x=0.5→  y=\frac{18}{0.5}=36

b. For x=1→  y=\frac{18}{1}=18

c. For x=2→  y=\frac{18}{2}=9

d. For x=3→  y=\frac{18}{3}=6

1. The prism below measures 6 inches x 3 inches x 10 inches. A diagonal
12345 [234]

9514 1404 393

Answer:

  √145 ≈ 12.04

Step-by-step explanation:

The length of the space diagonal is the root of the sum of the squares of the prism edge lengths:

  d² = a² +b² +c² = 6² +3² +10² = 145

  d = √145 ≈ 12.04 . . . inches

__

The face diagonal is found using the Pythagorean theorem in the usual way:

  f² = a² + b²

The space diagonal is the hypotenuse of the right triangle whose sides are the face diagonal and the remaining edge:

  d² = f² +c²

  d² = a² +b² +c²

__

Here is a diagram.

Solve the following proportion. P/6 = 7/8<br> A: P=5.25<br> B: P=8<br> C: P=10.5<br> D: P=42
ValentinkaMS [17]

Answer:

A

Step-by-step explanation:

given \frac{P}{6} = \frac{7}{8}

using the method of cross- multiplication then

8P = 42 ( divide both sides by 8 )

P = \frac{42}{8} = 5.25

tatyana61 [14]
7x+1000+x=89000

7x+x+1000-1000=89000-1000
8x=88000

8x/8=88000/8
x=$11000

what's the final volume of a gas with an initial volume of 75ml if the pressure decreases from 300ml to 200ml? A. 50.0ml B.112.5
aivan3 [116]
300 ml ... 200 ml
75 ml ... x = ?

If you would like to know what is the final volume of a gas, you can calculate this using the following steps:

300 * x = 200 * 75     /300
x = 200 * 75 / 300
x = 50.0 ml

The correct result would be A. 50.0 ml.
