Mid-ocean ridge rift zones produce new crust. Depending on the rift, 1 cm/yr to more than 10 cm/yr can be produced.
1. The distance between Newfoundland, Canada, and Ireland is roughly 3,320 kilometers. If the Mid-Atlantic Ridge is spreading at 4 cm/year (0.00004 km/year) in that area, how long ago did the Atlantic Ocean separate Canada from Ireland?
Answer:
1cm/year
Step-by-step explanation:
If the Mid-Atlantic Ridge is spreading 4cm/year, then it took 83000000 years for the Atlantic Ocean to separate Canada from Ireland.
What is the conversion of units?The conversion of units by using dimensional analysis is the changing of the unit of a particular parameter from one form to another.
This technique takes a logical approach when solving and converting from one unit to another.
From the given information:
A rift can be produced between 1cm/yr to more than 10 cm/yr
The separation between Canada and Ireland is roughly 3320 kilometers.
Then, the number of years it took the Atlantic Ocean to separate Canada from Ireland is:
[tex]\mathbf{= \dfrac{3320 \ km }{ 0.00004 \ km/year }}[/tex]
= 83000000 years

Usain Bolt ran a 5-k (5 kilometer) race in 7.5 minutes. You observe a rabbit run across your yard (a distance of 30 meters) in 2.4 seconds.
Who is faster, Usain Bolt or the rabbit? PLEASEE HELPP PLEASE YHIS IS DUE IN 10 MIN RN I WILL GOVE BRAINLIEST WITH EXPLANATION THANK YOU!
Answer:
Usain Bolt
Step-by-step explanation:
1 kilometer = 1,000So, 5 kilometers = 5,000 metersFind out their time per 1 meter:
Usain Bolt:
Set up a proportion: [tex]\frac{5000}{7.5} = \frac{1}{x}[/tex] Cross multiply, then divide: 1 × 7.5 = 7.5, 7.5 ÷ 5000 = 0.0015The rabbit:
Set up a proportion: [tex]\frac{30}{2.4} = \frac{1}{x}[/tex] Cross multiply, then divide: 1 × 2.4 = 2.4, 2.4 ÷ 30 = 0.08Compare the times:
Usain Bolt: 0.0015 minutes in 1 meterRabbit: 0.08 seconds in 1 meterBecause 0.0015 minutes is faster than 0.08 seconds, Usain Bolt is the answer.I hope this helps!

a fruit stan sells 4 avocados for $3 How much will it cost for 12 avocados
Answer:
$9
Step-by-step explanation:
It would cost $36. It is $3 for 4 avocados, so you would need to find out how many packs of 4 you would need. To do that, you do 12 divided by 4 which is 3. Then, to figure out the total cost, you would do 3 times 3 which is 9.

Nina has x coins. Clayton has 5 fewer coins than six times the number of coins Nina has. Write an expression for the total number of coins Nina and Clayton have altogether. Then simplify the expression.
Answer:
7x - 5
Step-by-step explanation:
Let
Nina = x coins
Clayton = 6x - 5 coins
Expression for the total number of coins Nina and Clayton have altogether.
Nina + Clayton
= x + (6x - 5)
= x + 6x - 5
= 7x - 5
The correct answer and expression is 7x - 5
Answer:
7x - 5
Just put the numbers in the right spots and add the numbers together.
Solve the equation.
a
-9x + 1 = -x + 17
O x=-8
O x = -2
Ox= 2
O x = 8
The solution of the given equation is x = -2.
What is an Equation?An equation is a mathematical statement containing two expressions on either sides which are connected with an equal to sign.
Either sides of an equation is called as left hand side and right hand side.
Given equation is,
-9x + 1 = -x + 17
We have to find the solution of the given equation.
Take the like terms together.
Subtracting one on both sides,
-9x = -x + 16
Adding x on both sides,
-8x = 16
Dividing by -8 on both sides,
x = -2
Hence the solution is x = -2.

Answer:
[tex] \huge{ \bold{ \boxed{ \tt{x = 11}}}}[/tex]
Step-by-step explanation:
[tex] \text{ - 10x + 17x - 2 = 5(x + 4)}[/tex]
Subtract 10x from 17x
10x and 17x are like terms. So, the coefficients of like terms can be added or subtracted.
[tex] \dashrightarrow{ \sf{ 7x - 2 = 5(x + 4)}}[/tex]
Distribute 5 through the parentheses
[tex] \dashrightarrow{ \sf{7x - 2 = 5 \times x + 5 \times 4}}[/tex]
[tex] \dashrightarrow{ \sf{7x - 2 = 5x + 20}}[/tex]
Move 5x to left hand side ( L.H.S ) and change it's sign
Similarly , move 2 to right hand side ( R.H.S ) and change it's sign
[tex] \dashrightarrow{ \sf{7x - 5x = 20 + 2}}[/tex]
Subtract 5x from 7x
[tex] \dashrightarrow{ \sf{2x = 20 + 2}}[/tex]
Add the numbers : 20 and 2
[tex] \dashrightarrow{ \sf{2x = 22}}[/tex]
Divide both sides by 2
[tex] \dashrightarrow{ \sf{ \frac{2x}{2} = \frac{22}{2}}} [/tex]
[tex] \dashrightarrow{ \boxed{ \sf{x = 11}}}[/tex]
--------------------------------------------------------------
Now, let's check whether the value of x is 11 or not.
Verification :L.H.S = n[tex] \sf{ - 10x + 17x - 2}[/tex]
Plug the value of x and simplify
[tex] \longrightarrow{ \sf{ - 10 \times 11 + 17 \times 11 - 2}}[/tex]
[tex] \longrightarrow{ \sf{ - 110 + 187 - 2}}[/tex]
[tex] \longrightarrow{ \sf{77 - 2}}[/tex]
[tex] \dashrightarrow{ \sf{75}}[/tex]
R.H.S = [tex] \sf{5(x + 4)}[/tex]
plug the value of x and simplify
[tex] \longrightarrow{ \sf{5(11 + 4)}}[/tex]
[tex] \longrightarrow{ \sf{5 \times \: 15}}[/tex]
[tex] \longrightarrow{ \sf{75}}[/tex]
L.H.S = R.H.S
The value of x is 11 .

What is the change in elevation between 8,500m and -300m
Answer: The change in elevation is 5,100 m.
Step-by-step explanation:
Since we have given that
Initial height = 8,500 m
New height = 3,400 m
We need to find the change in elevation:
As we know the change in elevation is the difference between the heights:
So, it becomes,
8500-3400
=5,100 m
Hence, the change in elevation is 5,100 m.
