Seafloor spreading can be defined as a process that involves the formation of new oceanic crust as a result of volcanic activities and an upwelling of molten magma at mid-ocean ridges, as well as a slowly increasing distance (outward movement) from the ridge.
The theory of seafloor spreading was established by Harry Hammond Hess and it can be used to explain in details the slowly increasing distance between South America and Africa which grows from the center.
What is a hot spot?A hot spot refers to an area deep within Earth's mantle or under the rocky outermost layer of Earth, from which heat rises through convection and acquired as heat energy by a landform.
In the United States of America, you will see a layered sedimentary rock that is exposed by erosion when you view the Grand Canyon.
Furthermore, Australia is made up of relatively old and thick continental crust. Also, subduction causes the formation of extremely deep ocean Marianas Trench.

100 POINTS TO ANYONE WHO ANSWERS THIS RIGHT
Answer:
11.8 m:
Step-by-step explanation:
Volume = pi×r²×h

Which expression correctly represents "nine less than the quotient of a number and four, increased by three"? StartFraction n Over 4 EndFraction minus 9 3 StartFraction 4 Over n EndFraction minus 9 3 9 minus StartFraction n Over 4 EndFraction 3 9 minus StartFraction 4 Over n EndFraction 3.
Answer:
n/4-9 +3
Step-by-step explanation:
to answer this question we have to analyze the information given.
The quotient of a number means the result of the division of 2 numbers.
In this case the numbers are: a number (n) and 4 . n/4
Nine less than that quotient means we have to subtract 9 to the quotient.
n/4-9
Increase by three: we simply have to add 3
n/4-9 +3

WILL GIVE BRAINLY PLEASE HELP!!!!!! In this triangle, what is the value of x? enter your answer, rounded to the nearest tenth, in the box.
Answer:
x ≈ 67.1
Step-by-step explanation:
The side adjacent to x° is given, along with the hypotenuse. That suggests the relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(x°) = 28/72 = 7/18
The angle is found from the cosine using the inverse cosine function:
x° = arccos(7/18)
x° ≈ 67.1°

Answer:
d) 35ft
e) 6 seconds
f) 250°
Step-by-step explanation:
If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.
36 secs = 360°
⇒ 1 sec = 360/36 = 10°
d) After 9 seconds, it has turned:
9 x 10 = 90°
Therefore, it will be 15 + 20 = 35ft from the wall
e) 60° = 6 seconds
f) 25 seconds = 25 x 10 = 250°
For a project in his Geometry class, Nathaniel uses a mirror on the ground to measure the height of his school’s flagpole. He walks a distance of 7.95 meters from the flagpole, then places a mirror on flat on the ground, marked with an X at the center. He then steps 1.15 meters to the other side of the mirror, until he can see the top of the flagpole clearly marked in the X. His partner measures the distance from his eyes to the ground to be 1.65 meters. How tall is the flagpole? Round your answer to the nearest hundredth of a meter.
The height of the flagpole to the nearest hundredth is 11.41 m
Similar shapesIn order to get the height of the flagpole, we will use the similarity theorem of shapes.
From the given diagram, we will have the expression
1.65/1.15 = x/7.95
Cross multiply
1.15x = 1.65 * 7.95
1.15x = 13.1175
x = 13.1175/1.15
x = 11.406
Hence the height of the flagpole to the nearest hundredth is 11.41 m

i write a test in 2 days and i dont know how to find percentages can anyone help me
percentage is a ratio of a number or fraction to 100
percentage =per(every) + cent (100)
per cent = per 100
percentage calculation formula (%) = (part / whole ) ×100
percentage increase equation = 100 ×( final - initial) /initial
ex1 : 2% is 2 percent = 2/100 =2:100
ex2: 35% = 35/100
48% = 48/100
ex3 : find the following 10% of 25,000
step 1 : convert 10% into fraction = 10/100
step 2 : multiply the fraction with value = 10/100× 25,000
answer = 2,500
ex4 : what is 7% of 68m ?
step 1 : convert 7% into fraction = 7/100
step 2 : multiply the fraction with value = 7/100 × 68
answer = 4.76 m
ex5 : The original price of a shirt was $10. It was decreased to $5 . What is the percent decrease of the price of this shirt?
step 1 : find the amount decreased = $10–$5 =$5
step 2 : write as part / whole = $5 / $10 = $0.5
step 3 : multiply by 100 = 0.5 × 100 = 50%
ex6 : Mary has a monthly salary of $21,000. She spends $350 per month on food. What percent of her monthly salary does she spend on food?
step 1 : write as part /whole and multiply by 100
= ( 350 / 21000 ) ×100 = 1.7 %
ex6 : The price of a pair of shoes was decreased by 21% to $100. What was the original price of the trousers?
step 1 : write % as fraction = 21/100
original price = y
(y × 21/100 ) = amount decreased --------- 1
y - amount decreased = $100 -------------- 2
rearrange equation 2 as;
y - $100 = amount decreased -------------- 3
when you equate both equation 1 and 3 you should get the ans y = $ 126.58
ex6 : The price of an item changed from $120 to $100. Then later the price decreased again from $100 to $80. Which of the two decreases was larger in percentage term?
step 1 : part / whole = (120 - 100) / 120 = 0.17 = 17%
step 2 : part / whole = (100 - 80) / 100 = 0.20 = 20%
The part were the same in both cases but the whole was smaller in the second decrease.
ex7 : A family had dinner in a restaurant and paid $35 for food. They also had to pay 9.5% sale tax and 10% for the tip. How much did they pay for the dinner?
for food = $35
sale tax = 9.5/100 × 35 = $3.33
tip = 10 /100 × 35 = 3.5
total = $45.83
ex8 : Smith invested $5000 for two years. For the first year, the rate of interest was 7% and the second year it was 8.5%. How much interest did he earn at the end of the two year period?
Answer
Interest at the end of the first year
7/100 * 5000 = $350
Interest at the end of the second year
8.5/100 * (5000 + 350) = $454.75
Total interest at the end of the two year period is
$350 + $454.75 = $804.75

A plant has an initial height of 2 inches and grows at a constant rate of 2 inches each month. A second plant that also grows at a constant rate has an initial height of 1 inch and is 29 inches tall after 1 year. After how many months are the plants the same height?
Answer:
Answer:4.8 monthsStep-by-step explanation:First, let's write down the information that we are given.Plant A: Initial Height: 3 in.Constant Rate of Growth (CRG): 2in/month (2 inches per month)Plant B:Initial Height: 1 in.CRG: 29in/year (29 inches per year)We can see that Plant B grows 29 inches per year, so lets convert Plant B's 'CGR' to months.Plant B - Divide by 12 (12 months in a year)29/12 in/yearNow, Lets put these into equations:Plant A: y = 2x + 3Plant B: y = 29/12 x + 1Now, set these two equations together and solve for x.2x + 3 = 29/12 x + 12 = 5/12 x4.8So, after 4.8 months, the plants will be the same height.

John walked 9 5/8 miles at an average speed of 1 3/4 MPH. How long did it take John to walk this distance?
Answer:
5 hours and 30 minutes
Step-by-step explanation:
Convert all fractions to decimals for easier division
9 and 5/8 = 9.625
1 and 3/4 = 1.75
Then divide 9.625 by 1.75 to get the hours amount
9.625 / 1.75 = 5.5
0.5 of an hour is 30 minutes, so the final answer is 5 hours and 30 minutes
Answer:
5.5 hours

Answer:
(3, -6)
Step-by-step explanation:
Both equations are equal to y, so you can make them equal to each other:
-2x = 5x-21
Get the same terms on the same side by subtracting 5x from both sides"
-7x = -21
Get x alone by dividing both sides by -7:
x = 3
The simplest way to find y is by filling in 3 for x in the first equation:
y = -2(3)
Multiply:
y = -6
Check your answer by filling in 3 for x in the second equation:
y = 5(3) - 21
Multiply:
y = 15 - 21
Subtract:
y = -6
To check both answers together, fill in 3 for x and -6 for y in both equations (although we already checked both answers above):
-6 = -2(3)
-6 = -6
-6 = 5(3) - 21
-6 = 15 - 21
-6 = -6
Answer:
3,-6
