wind resistance varies jointly as an objects surface area and velocity. if an object traveling at 55 miles per hour with a surfa

nikdorinn [45]

Answer:

25 miles per hour

Step-by-step explanation:

Given

$W = Wind\ resistance$

$A = Surface\ Area$

$V = Velocity$

The joint variation can be represented as:

$W\ \alpha\ A*V$

Where:

$V = 55; A = 20; W = 220$

Required

Find V, when: $A = 55; W = 275$

We have:

$W\ \alpha\ A*V$

Express as an equation

$W= k *A*V$

Where k is the constant of variation

Make k the subject

$k = \frac{W}{A*V}$

When: $V = 55; A = 20; W = 220$

We have:

$k = \frac{220}{20 *55 }$

$k = \frac{220}{1100}$

$k = 0.2$

When: $A = 55; W = 275$

We have:

$k = \frac{W}{A*V}$

Substitute: $A = 55; W = 275$ and $k = 0.2$

$0.2 = \frac{275}{55 * V}$

Make V the subject

$V= \frac{275}{55 * 0.2}$

$V= \frac{275}{11}$

$V= 25$

The length of a rectangle is twice its width<br> The perimeter of the rectangle is 43cm

boyakko [2]

Answer:

7.17 cm

Step-by-step explanation:

If the width is x, the length is twice this = 2x

And

Perimeter = 2 (W + L)

so

Perimeter = 2 ( x + 2x)

Perimeter = 2 (3x)

Perimeter = 6x

43 = 2 ( x + 2x )

43= 2 ( 3x)

43 = 6x

= 7.17 cm

Hope this helps i'm pretty sure this is how you do it :-)

Solve for the value of x 3x - 9 + 12 - 6x = -18

Zinaida [17]

Answer:

x=7

Step-by-step explanation:

$3x-9+12-6x=-18$

now let’s put together the like terms

$3-3x=-18$

$-3x=-21$

now we divide $-21$ By $-3$

the result is

$x=7$
