As streams flow through Stone Mountain, layers of sand build up. Over time, the sand particles form a sedimentary rock called sa

ndstone. What causes sandstone to change into metamorphic rock at Stone Mountain? Sandstone is reshaped by erosion from a stream. Sandstone builds up layers of sand at the mountain. Sandstone experiences intense heat and pressure. Sandstone has more sand particles compacted on top of it.

<u>Answer:</u>

The reason that causes the sandstone to turn into a metamorphic rock is that it experiences extreme heat and pressure.

<u>Explanation:</u>

  • When the process of sedimentation occurs due to the accumulation of sand for a "long period of time", the layers that were once at the top get buried deep under the overlaying layers of sand.
  • This initially results in the sedimentary rocks formation at the bottom of this accumulation.
  • Over time, the sedimentary rock at the bottom is subjected to extreme pressure and heat from above.
  • The action of extreme pressure and heat on the sedimentary rock converts it into a metamorphic rock.

a sweater originally priced at $80 was marked down by 25% what was the price of the sweaterTerry earns $250 salary plus $5 per s
Digiron [165]

Answer:

  1. $60
  2. 103 sales

Explanation:

1. The sweater was originally priced at $80 and then got marked down by 25%. The new price is;

= 80 * ( 1 - 25%)

= 80 * 0.75

= $60

2. Terry earns a basic salary of $250 plus $5 per sale. To make a total of $765, from sales commission alone Terry must make;

= 765 - 250

= $515

Sales to make = 515/5

= 103 sales

raketka [301]

Answer:

Explanation: The United States of America and Canada have one of the worlds oldest environmental partnerships. The various ways they're partnering to better the environment include:

1. The U.S. - Canada Air Quality Agreement.

This Agreement was signed in 1991 with the aim of working towards the reduction of air emissions which cause cause acid rain. The Agreement was later expanded in the year 2000 with the goal of reducing transboundary smog emissions under the Ozone Annex.

2. The Great Lakes Water Quality Agreement.

Adam, who is 5'6" tall, notices his shadow on the sidewalk. If the angle of elevation from the tip of the shadow to the sun is 6
german
<h2>Answer:</h2>

This problem can be solved using trigonomtry, assuming that the figure formed by Adam's shadow and Adam himself is a Right Triangle (as shown in the figure attached).


According to this,  the distance from the tip of the shadow to the top of Adam's head is the hypotenuse H of the triangle, and we already know Adam's height and the angle of elevation. So, the trigonometric function that best works in this case is sine:


sen(angle)=\frac{Oppositeleg}{hypotenuse}  


Where the opposite leg is the side of the triangle that is opposite to the 60\º angle.

In this especific case:


sen(60\º)=\frac{5.6feet}{H}     (1)


In order to know the value of the hypotenuse we have to find  H from equation (1):

H=\frac{5.6feet}{sen(60\º)}



H=6.4663 feet



Rounding:

H=6.46 feet>>>>>This is the distance from the tip of the shadow to the top of Adam's head
