Expanded form is the representation of a number with factors, exponents or words and separated into individual place values and decimal places that can form a mathematical expression. <span><span>8 </span><span>+ 0.4</span><span>+ 0.07</span><span>+ 0.008</span></span>

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.

Jeremy will roll a number cube, numbered 1-6, twice. What is the probability of rolling an even number than the number 3?

andreyandreev [35.5K]

There are 6 possible outcomes on a dice. Meaning when you roll it it could be any of them. Because 3 is one of the 6 the answer would be 1/6

The hotdog stand at a baseball game sells hotdogs for $3.50 each. The amount, D dollars, Mr. Moore paid for the hotdogs is direc

iVinArrow [24]

Answer:

D α H

k = D/H

k = 3.50

Step-by-step explanation:

Amount paid, D is directly proportional to the number of hotdogs, H

D = $3.50 per hot dog

D = $3.50 is directly proportional to 1 hotdog

Hence,

D α H

D = kH

k = proportionality constant

H = 1

3.50 = k

k = 3.50

k = D/H

María regala a su padre un best seller por su cumpleaños. Elige la encuadernación de tapas duras que tiene forma de prisma recta

iris [78.8K]

Answer:

<h2>María used only 792 square centimeters to cover the best seller.</h2>

Step-by-step explanation:

The volume of the best seller is about a rectangular prism, which is

$V= w \times l \times h$

Where $w$ is width, $l$ is length and $h$ is height.

In this case, we have

$w=12 \ cm\\l= 18 \ cm\\h= 6 \ cm$

Replacing values in the formula, we have

$V=12cm \times 18cm \times 6cm=1,296cm^{3}$

Now, according to the problem, 10% of paper covers the book, that means we need to find the suface area and then find the 90% of the paper missing. The formula for surface area is

$S=2wl+2lh+2hw$

Replacing values, we have

$S=2(12)(18)+2(18)(6)+2(6)(12)=432+216+144=792cm^{2}$

If 792 square centimeters is 10% of the total paper, then

$x=100\%\frac{792cm^{2} }{10\%} =7,920cm^{2}$

Therefore, there is 7,920 square centimeters of papers, but María used only 792 square centimeters to cover the best seller.
