Question

If TUVW is an isosceles trapezoid with TU parallel to WV , name a pair of similar triangles. Explain.

A.
by the SAS similarity theorem.
B.
by the SAS similarity theorem.
C.
by the AA similarity postulate.
D.
by the AA similarity postulate.

Answer 1

I think it is D

Answer 2

Angle-Angle (AA) Similarity Postulate. If two angles of one triangle are congruent to two angles of another. triangle, then the two triangles are similar- ffi.

Answer 3

UXV-WXT
TXU-WXV
WUV-TVW
TXU-VXW

Answer 4

those are the similar triangles

Answer 5

do you mind if i ask the other person who was w us for a second opinion?

Answer 6

No of course not, I would love to hear a second opinion. :)

Answer 7

@mathstudent55

Answer 8

ahh they're not online. why do you think it is D?

Answer 9

I think it is D because I looked up the definitions for similarity theorem and similarity postulate. I already knew it was angle angle because means that the triangles have two of their angles equal and parallel.

Answer 10

AA means they have to be in two different triangle or parallel, but always equal.

Answer 11

The surface areas of two similar solids are 1008 cm^2 and 1372 cm^2 The volume of the larger solid is 1801 cm^3. Find the volume of the smaller solid. Round your answer to the nearest hundredth.

Answer 12

a) 252.15
b) 1134.16
c) 1323.18
d) 1372.19

Answer 13

Answer 14

A scale factor represents the ratio of corresponding sides in similar figures.
(scale factor)^2 => area ratio
(scale factor)^3 => volume ratio

√( 2023/1183) = 17 / 13
(17/13)^3 = 4913 / 2197
4913 / 2197 = 2333 / x
x = 1043.27 in^3

Answer 15

but that's not an answer choice

Answer 16

i already saw that on yahoo answers lol

Answer 17

those aren't the right numbers

Answer 18

oops ment 1134.20cm^3

Answer 19

I rounded

Answer 20

If a sphere’s radius is quadrupled, what is the corresponding change in surface area?
A.
The surface area is quadrupled.
B.
The surface area is multiplied by 8.
C.
The surface area is multiplied by 16.
D.
The surface area is doubled.

@iwanttolearn1212 keep the medal I don't want it

Answer 22

well can you still help me? you deserve the medal

Answer 23

yeahI am still helping you but for the other question

Answer 24

ok then!

Answer 25

SA=4 pi r^2

if you double the radius, it's quadrupled. answer is B.

4 pi (2r)^2 = 16 pi r^2

Answer 26

C I mean LOL

Answer 28

A.
lower quartile = 38, upper quartile = 47, interquartile range = 9
B.
lower quartile = 45, upper quartile = 50, interquartile range = 5
C.
lower quartile = 47, upper quartile = 53, interquartile range = 6
D.
lower quartile = 45, upper quartile = 47, interquartile range = 2

Answer 29

Use the box-and-whisker plot below to identify the lower quartile, upper quartile, and interquartile range of the data set the plot represents.

Answer 30

B

Answer 31

The lower quartile is on the left side of the box. The higher quartile is on the right side of the box. :)

Answer 32

cool i have more! lol

Answer 33

you are amazing

Answer 34

LOL cool

Answer 35

thanks
