The image below is a triangle drawn inside a circle with center O:Which of the following expressions shows the area, in square inches, of the circle?
(π = 3.14)
3.14 · 42
3.14 · 52
3.14 · 5
3.14 · 22

the diameter of the circle is 8" so the radius is 8/2

- muscrat123

4

- anonymous

area of circle is 4^2π

- muscrat123

16 times pi

- anonymous

now lets find the area of the triangle

- muscrat123

i think we only need to find the circle/

- anonymous

yea

- muscrat123

so a?

In triangle XYZ, z2 = x2 + y2.
Which equation is true about the measure of the angles of the triangle?
The measure of angle XZY is equal to 90 degrees
The measure of angle XYZ is equal to 100 degrees
The measure of angle XYZ plus the measure of angle YXZ is equal to 80 degrees
The measure of angle XYZ plus the measure of angle YXZ is equal to 70 degrees

its not in the option

- anonymous

first one is true

- muscrat123

so a?

- anonymous

this stuff is a right angle triangle thats why it runs with pythagoras theorem

- anonymous

yea

Triangle ABC with vertices A(4, −6), B(2, −8), and C(−10, 4) is dilated by a scale factor of 2 to obtain triangle A′B′C′. Which statement best describes triangle A′B′C′?
It is similar to triangle ABC and has coordinates A′(2, −3), B′(1, −4), and C′(−5, 2).
It is similar to triangle ABC and has coordinates A′(8, −12), B′(4, −16), and C′(−20, 8).
It is congruent to triangle ABC and has coordinates A′(2, −3), B′(1, −4), and C′(−5, 2).
It is congruent to triangle ABC and has coordinates A′(8, −12), B′(4, −16), and C′(−20, 8).
there is no picture

- anonymous

imagine it being cut like that

- anonymous

dilation means scaled down so this thing reduced by half in size

- anonymous

congruent means they are equal length in all sides

- anonymous

you should know the answers by now

- muscrat123

i know that i just dont know how to do it:(

- anonymous

|dw:1438954561117:dw|

- anonymous

now if we scale this down by a factor of 2 we cut down the length of all the sides of all sides by half

- muscrat123

it is going to be similar bc we r cutting the size down to half

- anonymous

yes similar but not congruent

- muscrat123

what would be the coordinates?

- anonymous

thats not very important, whats important is that you must know the distance between the points cannot be larger than the original triangle

- anonymous

since this is a multiple choice question you can test it out

- anonymous

divide the coordinates of the original triangle by 2

- muscrat123

?

- anonymous

A(4, −6), B(2, −8), and C(−10, 4)
New triangle: A (4/2, -6/2) B (2/2, -8/2) C (-10/2,4/2)

- muscrat123

2,-3

- muscrat123

is it a ?

- anonymous

yep

Jamie has a deck of 60 sports cards, of which some are baseball cards and some are football cards. Jamie pulls out a card randomly from the deck, records its type, and replaces it in the deck. Jamie has already recorded six baseball cards and nine football cards. Based on these data, what is, most likely, the number of baseball cards in the deck?
12
15
24
30
c, correct?

Which sequence of transformations will change figure PQRS to figure P′Q′R′S′?
Counterclockwise rotation about the origin by 90 degrees followed by reflection over the x-axis
Counterclockwise rotation about the origin by 90 degrees followed by reflection over the y-axis
Counterclockwise rotation about the origin by 180 degrees followed by reflection over the x-axis

is it a?

- anonymous

definitely the last 2 options

- muscrat123

c?

- anonymous

lemme check, i dont remember a thing about those already

- anonymous

yea its A

- anonymous

rotate to 4th quadrant then reflection to 1st quadrant from x-axis

- muscrat123

really? i usually never get these right

- anonymous

|dw:1438955704612:dw|

- muscrat123

thank u so much i got a 93 :)

- anonymous

a is the only option that fits in

- anonymous

lol yw

- muscrat123

will u be available later?

- anonymous

maybe

- anonymous

sometimes i fall asleep with my pc on

- anonymous
