Answer:

None. The movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth’s mantle below the crust.

Step-by-step explanation:

Plate tectonics is the scientific theory explaining the movement of the earth’s crust. It is widely accepted by scientists today. Recall that both continental landmasses and the ocean floor are part of the earth’s crust, and that the crust is broken into individual pieces called tectonic plates (Fig. 7.14). The movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth’s mantle below the crust. Earthquakes and volcanoes are the short-term results of this tectonic movement. The long-term result of plate tectonics is the movement of entire continents over millions of years (Fig. 7.18). The presence of the same type of fossils on continents that are now widely separated is evidence that continents have moved over geological history.

In the figure, what is the value of x?
maks197457 [2]

Answer:x=90 °


Step-by-step explanation:

In any circle the exterior angle formed is half of the major arc - minor arc .

Angle formed by tangents or secants = \frac{1}{2}(Major arc - minor arc )

The sum of measure of arcs inany circle is 360°.

Minor arc is given as x°.So Major arc = 360-x.

Substituting the given values in the formula :

x=\frac{1}{2}(360-x-x)

x=\frac{1}{2}(360-2x)

x=180-x

Adding x both sides we have:

2x=180.

Dividing both sides by 2.x= 90.

The null hypothesis and the alternate hypothesis are: H0: The frequencies are equal. H1: The frequencies are not equal. Category
OLga [1]

Answer:

Reject H0

Step-by-step explanation:

Given :

H0: The frequencies are equal. H1: The frequencies are not equal

Category f0 A 10 B 30 C 30 D 10

Total f0 = (10 + 30 + 30 + 10) = 80

Expected frequency is the same for all categories :

Expected frequency = 1/4 * 80 = 20

χ² = Σ(observed - Expected)² / Expected

χ² = (10-20)^2 / 20 + (30-20)^2 /20 + (30-20)^2 / 20 + (10-20)^2 / 20

χ² = (5 + 5 + 5 + 5) = 20

Andres Michael bought a new boat. He took out a loan for S24 320 at 45% interest for 2 years. He made a 54.110 partial payment a
AleksAgata [21]

Answer:

$25,381.94

Step-by-step explanation:

45% interest in 2 years = 45/24 = 1.875% monthly

<u>Debt at month 0</u> (when Andres got the loan)

24,320

<u>Debt at month 1</u>

24,320*(1 + 0.001875) = 24,365.6

<u>Debt at month 2</u>

24,365.6*(1.001875) - 54.110 (partial payment) = 24,357.1755

<u>Debt at month 3</u>

24,357.1755*(1.001875)

<u>Debt at month 4</u>

24,357.1755*(1.001875)^2

<u>Debt at month 5</u>

24,357.1755*(1.001875)^3

<u>Debt at month 6</u>

24,357.1755*(1.001875)^4 - 3,410 (partial payment)

= 24,540.36874

<u>Debt at month 7</u>

24,540.36874*(1.001875)

<u>Debt at month 8</u>

24,540.36874*(1.001875)^2

<u>Debt at month 9</u>

24,540.36874*(1.001875)^3

<em>and so on</em> until month 24 (the maturity)

<u>Debt at maturity</u>

24,540.36874*(1.001875)^{18}

= 25,381.93916 = $25,381.94 rounded to the nearest hundreth.
