or anybody else good with math?

Answer 1

@saseal

Answer 2

yea

Answer 3

okay thanks so much

Answer 4

what is your question?

Answer 5

hang on

Answer 6

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

Answer 7

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

Answer 8

4

Answer 9

area of circle is 4^2π

Answer 10

16 times pi

Answer 11

now lets find the area of the triangle

Answer 12

i think we only need to find the circle/

Answer 13

yea

Answer 14

so a?

Answer 15

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

Answer 16

its not in the option

Answer 17

first one is true

Answer 18

so a?

Answer 19

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

Answer 20

yea

Answer 21

A wooden block in the shape of a rectangular pyramid is shown below:
If a cross section of the block is cut perpendicular to the base but does not pass through the top vertex, which of the following shapes describes the cross section?

Triangle
Rectangle
Trapezoid
Hexagon

Answer 22

trapezoid

Answer 23

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

Answer 24

imagine it being cut like that

Answer 25

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

Answer 26

congruent means they are equal length in all sides

Answer 27

you should know the answers by now

Answer 28

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

Answer 29

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

Answer 30

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

Answer 31

yes similar but not congruent

Answer 32

what would be the coordinates?

Answer 33

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

Answer 34

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

Answer 35

divide the coordinates of the original triangle by 2

Answer 36

?

Answer 37

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)

Answer 38

2,-3

Answer 39

is it a ?

Answer 40

yep

Answer 41

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?

Answer 42

yea c

Answer 43

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
Counterclockwise rotation about the origin by 180 degrees followed by reflection over the y-axis

Answer 44

is it a?

Answer 45

definitely the last 2 options

Answer 46

c?

Answer 47

lemme check, i dont remember a thing about those already

Answer 48

yea its A
