Question

can someone please help me?

Answer 1

the answer is not A or D

Answer 2

I agree: the answer is neither A nor D.
But that leaves us with 2 possible answers.
What principles of geometry can you think of that would apply to this problem and thus help you choose B or C?
What does "congruent" mean to you in this context?

Answer 3

I meant B?

Answer 4

Dolly, I'd love to help, and will help, but do ask you to think this problem through and to answer my questions, such as "what does congruent mean to you?? first.

Answer 5

That property, "congruent," is the key to understanding this problem. I would like you to finish this problem knowing how to obtain the answer yourself, and that's why I won't be telling you right up front what I think the answer is.

Answer 6

So: two angles are congruent if ... what?

Answer 7

Congruent means have the same size ,shape, and measure. (corresponding angles should be equal and proprtional)

Answer 8

@mathmale, I gave the definition

Answer 9

Are angles X and E congruent? If y ou think they are, explain why. if you think they're not, explain why.

Answer 10

the answer is C because angle X is congruent to angle Z

Answer 11

@mathmale

Answer 12

it is c

Answer 13

thank you guys so much :)

Answer 14

The surface area of a triangular pyramid is 375.2 m2.

What would change if the surface area were measured in square centimeters?



A.
The surface area of the pyramid would decrease.


B.
The surface area of the pyramid would increase.


C.
The surface area of the pyramid would stay the same, but the number representing the surface area would decrease.


D.
The surface area of the pyramid would stay the same, but the number representing the surface area would increase.

Answer 15

@mathmale can you please help my friend @lilyryan with this question?

Answer 16

@lilyryan : Looks as though you've posted your question at the end of someone else's post. Please, would you post your question separately? On the left side of the screen, under the blue line, is a box that says, "Ask a question." type your question there next time, and I'll be happy to help you with it. Since Dolly has asked me to help you with this present question, I will gladly do so:

Answer 17

@lilyryan, mathmale is glad to help :)

Answer 18

The surface area of a triangular pyramid is 375.2 m^2, or 375.2 square meters.

Answer 19

thanks your my bff

Answer 20

no problem I hope you understand the question :)

Answer 21

yea

Answer 22

my real name is destiny

Answer 23

what yours

Answer 24

Supposing we wanted to convert that to square centimeters, what would we do?

Are you familiar with the unit, centimeter, which is 1/100 th of a meter? In other words, 100 cm = 1 meter. Hello, Destiny! Warren Goldmann.

Answer 25

OpenStudy is apparently being heavily used, so responses are slow.

Answer 26

If you can accept this: 100 cm = 1 meter,
then we can convert that to a conversion factor:

100 cm
-----------
1 meter

Answer 27

The volume of a cube is 512 cm3. What would change if the volume of the cube were measured in cubic meters?

Answer 28

You have the surface area as A = 375.2 square meters.

If we take that and multiply it by (100 cm)^2/(1 m^2, we'll get
\[\frac{ 375.2 m ^{2} }{ 1 }*\frac{ (100 cm)^{2} }{ (1 m)^{2} }\]

Answer 29

Destiny: Please look at that expression carefully. Can you see how to reduce/simplify it? If you do this, y ou'll end up with the AREA in cm^2 instead of in m^2.

Answer 30

@lilyryan : If you'll look at that expression I typed in immediately above, you'll see \[m ^{2}\]
in both numerator and denominator. If y ou cancel those out, you'll be left with the surface area of this pyramid iexpressed in cm^2 instead of m^2.

Please let me know if you have further questions.
