Answer:
15 ft
Step-by-step explanation:
10 + 5 = 15 ft
- The slowly increasing distance between South America and Africa is due to: a. <u>Seafloor Spreading</u>.
- Old Faithful Geyser at Yellowstone National Park in the United States of America acquires its energy from a: b. Hot Spot.
- Layered <u>sedimentary rock</u> exposed by erosion can be seen when looking at the Grand Canyon in the United States of America.
- Australia is made up of relatively old and thick: d. Continental Crust.
- The extremely deep ocean Marianas Trench is a result of: g. Subduction.
- <u>Seafloor Crust</u>: found in the Atlantic Ocean between North America and Europe comprises dense and relatively young rock.
- The earthquakes that occur in Southern California generally occur above a: f. Fault.
<h3>What is seafloor spreading?</h3>
<u>Seafloor spreading</u> 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 <u>seafloor spreading</u> 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.
<h3>What is a
hot spot?</h3>
A <u>hot spot</u> 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 <u>sedimentary rock</u> that is exposed by erosion when you view the Grand Canyon.
Furthermore, Australia is made up of relatively old and thick <u>continental crust</u>. Also, <u>subduction</u> causes the formation of extremely deep ocean Marianas Trench.

Answer:
2
Step-by-step explanation:
12x12 = 144
14x14 = 196
144 + ? = 196
196 - 144 = 52
= 2
We can put this information into two equations:
7 booklets = 140 stamps
3 booklets = 60 stamps
Let us then focus on one equation to find the relationship:
7 booklets = 140 stamps
If we put that into a fraction, we get
or
.
This means that for every booklet, Ashley gets 20 stamps; or rather, each booklet has 20 stamps.
We can then see that this relationship holds true for the second equation as well:
or
.
To write a general equation for this relationship using
p for the number of postage stamps, and
b for the number of booklets:
p = 20b
Where
b is equal to
p.
Subtract 43 from both sides
-6p=-30
Divide both sides by -6
p=5
Final answer: p=5
