1. Annel sells a phone which costs $180 and earns 5% commission. What is the dollar amount of commission that Annel earns?
A $189
B $9
C $109
D $90

B) $9

Step-by-step explanation:

5% can also be written as 0.05

Dividing a percentage by 100 gives you decimal form.

The question is asking for the amount of commission earned, not the total amount. This means that all we have to do is do:

$180 x 0.05 = $9

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

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
