Answer:

Step-by-step explanation:

Convergent:  Two plates are coming together.  This results in one or both edges of the plates to move upwards to form mountains.  If one plate is pushed down while the second is pused up, a deep trench may form (ocean trenches).  Volcanoes and earthquakes may also form along this boundary.  The Pacific "Ring of Fire" is due to convergent plate collisions.

Divergent: Divergent boundaries occur when two plates move away from each other. Earthquakes and volcanoes are common as the growing gap allows magma to comes to the surface.  Iceland is divided between the North American and Eurasian plates and this has produced an ever-widenng gap down the center of the country, which is both a major tourist attraction and a source for volcanic activity and numerous hot spring pools.  One bridge across this gap is known as the "Bridge Between Continents," and is designed to accomodate the Xcm/year stretch as the continents separate even further.

Transform:  Two plates slide past each.  The San Andreas fault is one of the more famous.  Structures, both natural and man-made, that cross a transform boundary can be split into pieces and moved in opposite directions. Rocks along the boundary are pulverized as the plates grind them.  This can result in a linear fault valley or undersea canyon. Earthquakes are common along these faults. Unlike convergent and divergent boundaries, crust is cracked and broken at transform margins, but is not created or destroyed as with convergent and divergent boundaries.

Answer:

There are two solutions for x;

x = 0

x = [tex]-\frac{3}{2}[/tex]

Step-by-step explanation:

Answer:

x = 0 or -3/2

Step-by-step explanation:

( 2 x +  3 ) ^2  −  6 x −  9  =  0 ---> distribute

4x^2 + 6x + 6x + 9 - 6x - 9 = 0 --> add the 9's together

4x^2 + 12x  - 6x = 0 --> combine like terms

4x^2 + 6x = 0 --> common factor

2(2x^2 + 3x) = 0 --> divide by 2 on both sides

2x^2 + 3x = 0

then you should use the quadratic formula (can't add here or the explanation would take too long)

Hey!

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

We Know:

$220 per week.

$0.15 per mile you drive.

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

Solution:

325 - 220 = 105

105 / 0.15 = 700

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

Answer:

You can drive 700 miles in one week for $325!

Hope this helped! Good Luck ;)

Answer:

96

Step-by-step explanation:

The length of the large rectangle is: 5 units

The width of the large rectangle is: 7 units

- > Area of the large rectangle = length × width  = 7*5 = 35 square units

The length of the middle rectangle is: 7 units

The width of the middle rectangle is: 4 units

- > Area of the middle rectangle = length × width  = 7*4 = 28 square units

The length of the small rectangle is: 7 units

The width of the small rectangle is: 3 units        

- > Area of the small rectangle = length × width  = 7*3 = 21 square units

Area of top and the bottom triangles =2* 1/2(bh) = 4*3 = 12 square units

Then we find the total surface surface area by adding up all of these  

- > 35 + 28 + 21 + 12 = 96 square units

Answer:

So because the range is between 20 and 40, it can be noticed through counting.

5, 10, 15, 20, 25, 30, 35, 40

3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39

The number of balls in the box, just from the information by 5, is either ending in 1 (for example 21, 31) or 6 (26, 36)

From counting by 3 with that information, it would mean the number is most likely 26 balls, since there would be one left when Max reaches 25 counting by 5, and two left when he reaches 24 counting by 3.

so sorry i couldn't make it a fraction :(

Answer:

Answer:

[tex] \frac{x}{3} = \frac{7x}{12x - 15} \\ 12 {x}^{2} - 15x = 21x \\ 12 {x}^{2} -36x = 0 \\ 12x(x - 3) = 0 \\ \boxed{x = 0} \: or \: \boxed{x = 3} \\ \\ \frac{25 - 3x}{x + 5} = 1 \\ 25 - 3x = x + 5 \\ 3x + x = 25 - 5 \\ 4x = 20 \\ \boxed{ x = 5} \\ \\ \frac{3x - 2}{x} = - \frac{8}{x} \\ 3 {x}^{2} - 2x = - 8x \\ 3 {x}^{2} -6x = 0 \\ 3x(x - 2) = 0 \\ \boxed{x = 0} \: or \: \boxed{x = 2} \\ \\ \frac{3 - x}{x} = \frac{x + 1}{2x} \\ 6x - 2 {x}^{2} = {x}^{2} + x \\ 3 {x}^{2} - 5x = 0 \\ x(3x - 5) = 0 \\ \boxed{x = 0} \: or \: \boxed{x = \frac{5}{3} }[/tex]

Answer:

Step-by-step explanation:

The question is slightly ambiguous. The problem is, do you find the first 40 hours using 10x and then the second equation using x >40. I don't think so, but it should be made clear. It turns out that the first 40 hours does equal 400 so that you can use the second expression with no worries.

w(53) = 15(53 - 40) + 400

w(53) = 15(13) + 400

w(53) = 195 + 400

w(53) = 595
