okay thanks so much
what is your question?
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
area of circle is 4^2π
16 times pi
now lets find the area of the triangle
i think we only need to find the circle/
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
first one is true
this stuff is a right angle triangle thats why it runs with pythagoras theorem
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
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
imagine it being cut like that
dilation means scaled down so this thing reduced by half in size
congruent means they are equal length in all sides
you should know the answers by now
i know that i just dont know how to do it:(
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
it is going to be similar bc we r cutting the size down to half
yes similar but not congruent
what would be the coordinates?
thats not very important, whats important is that you must know the distance between the points cannot be larger than the original triangle
since this is a multiple choice question you can test it out
divide the coordinates of the original triangle by 2
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)
is it a ?
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 Counterclockwise rotation about the origin by 180 degrees followed by reflection over the y-axis
is it a?
definitely the last 2 options
lemme check, i dont remember a thing about those already
yea its A
rotate to 4th quadrant then reflection to 1st quadrant from x-axis
really? i usually never get these right
thank u so much i got a 93 :)
a is the only option that fits in
will u be available later?
sometimes i fall asleep with my pc on
if i dont reply within 20mins, im prolly sleeping or playing dota2
