A, Sketch of a heterogeneous plate, modelled as a cylindrically symmetric region that is thicker owing to a combination of greater depletion and lack of extension. b, Rock uplift at the edge and at the centre of the 'plateau' over 50 Myr of conductive relaxation for different values of d (w = d/10 and h = 100 km) and Tb, the initial basal temperature before mid-Tertiary time (modelled as t = 0), assumed to be the time of the thermal perturbation due to removal of the Farallon plate. The smaller symbols correspond to Te = 20 km and the larger to Te = 30 km (ref. 19). The observed range in residual rock uplift of the Colorado Plateau (Fig. 1d) is indicated by the grey regions. c, Lateral migration of the 1,200 °C isotherm at 180-km depth as a function of d and h (results shown are for Tb = 1,300 °C). The slope of the lines represents the migration rate, which is a strong function of w, as illustrated by the lines with the smallest black symbols and fastest rate of encroachment: d = 800 km and w = d/100. All other results are shown for a larger value, w = d/10. Grey bars indicate rates observed in the migration of the onset of magmatism in Fig. 2b. d, Spatiotemporal pattern of rock uplift (every 5 Myr) for d = 800 km, w = d/100, Te = 30 km and Tb = 400 °C, showing higher values at the margins than in the interior and migration of the point of highest uplift slightly in from the margins of the plateau.

Step-by-step explanation:

45x+34=24x+16

collect like terms, we now have;

45x-24x=16-34

21x=-18

Maria used one bag of flour. She baked

AveGali [126]

Answer:

Answer is 11.

Step-by-step explanation:

Maria used two loaves of bread , One loaf is equal=2 1/4 cups so two becomes 2 ×2 1/4= 9/2

Maria makes the remaing 48 muffins of the flour left so,

One muffin is equal 3 1/4 cups so two becomes 2×3 1/4=13/2

Add both of them

9/2+13/2=11

The three angle bisectors of ΔABC intersect at point P. Point P is the

lisabon 2012 [21]

<h3>Answer: C) incenter</h3>

========================================

Explanation:

If you were to intersect the angle bisectors (at least two of them), then you would locate the incenter. The incenter is the center of the incircle which is a circle where it is as large as possible, but does not spill over and outside the triangle. Therefore this circle fits snugly inside the triangle.

--------------

extra notes:

* The centroid is found by intersecting at least two median lines

* The circumcenter is found by intersecting at least two perpendicular bisector lines

* The orthocenter is found by intersecting at least two altitude lines

* The incenter is always inside the triangle; hence the "in" as part of the name. The centroid shares this property as well because the medians are completely contained within any triangle. The other two centers aren't always guaranteed to be inside the triangle.

* The red lines cut each angle of the triangle into two equal or congruent pieces.

PLEASE help with these questions?? there are 7 of them! Thank you!!

We know in these kind of triangles that have a 90 degrees angle, we can do:

${a}^{2} + {b}^{2} = {c}^{2}$

so the first question:

$\sqrt{ {99}^{2} + {20}^{2} } = 101$

and then:

$b = \sqrt{ {17}^{2} - {15}^{2} } = 8$

so , when you want to rationalize , usually you must multiply the irrational factor as 1:

$\frac{ \sqrt{15} }{ \sqrt{15} } = 1$

so , now multiply:

$\frac{3}{ \sqrt{15} } \times \frac{ \sqrt{15} }{ \sqrt{15} } = \frac{3 \sqrt{15} }{15} = \frac{ \sqrt{15} }{5}$

in the next question,we know negative numbers in radical don't have any solution so 2 is correct,
