PLEASE HELP ME THIS IS DUE IN TWO HOURS! :(
Damm [24]

Answer:

2.0 x 10^{1}

Step-by-step explanation:

1. length = 3.2 x 10^{5} m

width = 1.6 x 10^{4} m

Area of a rectangle = length x width

                                = (3.2 x 10^{5}) x (1.6 x 10^{4})

                                = 5.12 x 10^{9} m^{2}

2. length = 1.28 x 10^{7} m

   width = 8 x 10^{3} m

Area of a rectangle = length x width

                                 = (1.28 x 10^{7}) x (8 x 10^{3})

                                 = 1.024 x 10^{11} m^{2}

\frac{Area of rectangle 2}{Area of rectangle 1} = \frac{1.024*10^{11} }{5.12*10^{9} }

                       = 20

                       = 2.0 x 10^{1}

Thus,

The area of rectangle 2 is 2.0 x 10^{1} times greater than the area of rectangle 1.

The diameter of a sphere is 4 centimeters. Which represents the volume of the sphere?
soldier1979 [14.2K]

Answer:

32\pi/3 cm³

Step-by-step explanation:

If the diameter is 4 cm, then the radius is 2 cm.

Use the sphere volume formula:

V = 4/3\pir³

Plug in the radius and solve:

V = 4/3\pi(2)³

V = 4/3\pi(8)

V = 32\pi/3

So, the volume of the sphere is 32\pi/3 cm³

I need to find how many solutions does the system have. ​
REY [17]
From what I got there is one real solution :)

Rearrange the second equation to give y=2-2x, substitute into the first equation to give you a value for x and then using that you can work out y for the exact coordinates of intersection :)

Also they are both straight line graphs so they will either have one or no solutions

Hope this helped :)

5x+5y=-30 find the x and y intercept
Masja [62]

<em>The x and y intercept of 5x + 5y = -30 are (-6, 0) and (0, -6) respectively.</em>

<h2 /><h2>Explanation:</h2>

The Standard Form of the equation of a line is given by:

Ax+By=C \\ \\ A,B,C \ Real \ Constants \ and \ A>0

So:

5x+5y=-30

is written in Standard Form. The x and y intercepts are:

x-intercept: \ (x,0) \\ \\ y-intercept: \ (0,y)

So:

FOR X-INTERCEPT:

Let's \ set: \\ y=0 \\ \\ 5x+5(0)=-30 \\ \\ Isolating \ x: \\ \\ 5x=-30 \\ \\ x=-\frac{30}{5} \\ \\ \boxed{x=-6}

FOR Y-INTERCEPT:

Let's \ set: \\ x=0 \\ \\ 5(0)+5y=-30 \\ \\ Isolating \ x: \\ \\ 5y=-30 \\ \\ y=-\frac{30}{5} \\ \\ \boxed{y=-6}

Finally,<em> the x and y intercept of 5x + 5y = -30 are (-6, 0) and (0, -6) respectively.</em>
