n = 1.2 E 12

m = 2.4 E14

\frac{n}{m}=\frac{1.2\times10^{12}}{2.4\times10^{14}}=\frac{1.2}{2.4}\times10^{12-14}=\frac{1.2}{2.4}\times10^{-2}=0.5\times10^{-2}=5\times10^{-3}

Name the postulate or theorem you can use to prove the triangles congruent.
r-ruslan [8.4K]
The question is referred to a particular pair of triangles.

They are two "siamese" right triangles. The side that they share is the hypotenuse of both triangles.

The other sides that are marked as congruent are the heights of each triangle.

Then, you can use the Hypotenuse  Leg theorem to prove the congruence of both triangles.

The hypotenuse  leg theorem states that any two rigth triangles that have congruent hypotenuse and a corresponding, congruent leg are congruent triangles.

84 is 60% of what number?
Fudgin [204]

To convert a percent to a decimal, you divide by 100.


60% = 0.60


If x is the unknown number, the word is means equal


84 = 0.60 * x


Divide both sides by 0.60


84/0.60 = (0.60/0.60)* x = x


140 = x

One of the same side angles of two parallel lines is five times smaller than the other one. Find the measures of these two angle
shutvik [7]

Answer:

30 and 150

Step-by-step explanation:

Whether these are same side interior or same side exterior, the sum of them is 180 when the angles are on the same side of a transversal that cuts a pair of parallel lines.  Let's call the angles A and B.  If angle A is 5 times smaller than angle B, then angle B is 5 times larger than angle A.  So the angles are x and 5x.  They are supplementary so

x + 5x = 180 and

6x = 180 so

x = 30 and 5(30) = 150

. In Problem 2, how many lateral faces would there be if the base had
Alla [95]

The number of lateral faces for a hexagonal prism or pyramid is 6.

<h3>What is a prism?</h3>

A prism is a three dimensional figure consisting of pair of opposite bases and lateral faces which are parallelogram.

Given that the base off the prism has two sides of length 3 inches and four sides of length 2 inches. Hence the base is hexagonal. The lateral faces would be 6.

The number of lateral faces for a hexagonal prism or pyramid is 6.
