The rocket is traveling at 4.9 miles per second, which is the same as 17,640
miles per hour, because 4.9*60*60=17,640

Now convert 17,640 MPH to KPH
The rocket is traveling 28,328.8 Kilometers per Hour
Hope this Helps!!

The perimeter of a rectangle is 40cm. If the length were doubled and the width halved, the perimeter would be increased by 16cm.

Arada [10]

Answer:

The dimensions of the original rectangle are Length =12cm, Width=8cm

Step-by-step explanation

Let the length of the rectangle be x

Let the width of the rectangle be y

The perimeter of a rectangle is 40cm.

2(x+y)=40

Divide both sides by 2

x+y=20

If the length were doubled(2x) and the width halved(y/2), the perimeter would be increased by 16cm,i.e.(40+16)cm

Therefore:

Divide both sides by 2

From the first equation, x=20-y.

Substitute x=20-y into

A line goes through the points (0, -5) and (-3, -3). Find the slope, and then use the point that is the y-intercept to write the

ValentinkaMS [17]

Answer:

y = -(2/3)x - 5

Step-by-step explanation:

y-int = -5

m = rise/run

m = (-5-(-3))/(0-(-3))

m = -(2/3)

therefore,

y = -(2/3)x - 5

Which equation represents a line that passes through (-2, 4) and has a slope of 2/5

Ulleksa [173]

Answer:

The equation of line is $5(y-4) = 2( x+2)$

$2 x-5 y+24=0$

Step-by-step explanation:

Given slope is $m = \frac{2}{5}$ and passes through (-2,4)

$y-y_{1}= m(x-x_{1} )$

$y-4 = \frac{2}{5}(x-(-2))$

$5(y-4) = 2( x+2)$

$2 x-5 y+24=0$

Explain why it is possible to draw more than two different rectangles with an area of 36 square units, but it is not possible to

Inessa05 [86]

Answer:

Step-by-step explanation

you are able to make two squares because you can use the square root of 36 and that twill give you 6 not a decimal.

in comparison if you do the square root of 15 it will give you 3.87298335
