Nikita's work
area of base = b = 3 bn=(718) = 28 cm?
volume=bh= (28)(13) = 364 cm
where, if any, did nikita first make a mistake in her work?
nikita used the wrong formula for the area of the base.
nikita used the wrong measurements when finding the area of the base.
nikita used the wrong formula for the volume of the prism.
nikita did not make a mistake.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

step-by-step explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
