Answer:
x=14
Step-by-step explanation:
Since the triangles are similar, you first line up the sides. Then, because the 16 and the 24 line up together, you divide them to find out how much bigger the first triangle is, which is 3/2 or 1.5. After that, you can see that the 21 and the x are on the same side, so you would divide 21 by 1.5 or 3/2 to get x. 21÷1.5=14.
x=14
Answer:
6π
Step-by-step explanation:
(135/360)×π×4²
(135/360)×π×16
=6π
The answer is roughly 21.4 copies per minute
an estimate
you multiply the oposite of the radical
i.e. 3-RADICAL 75 oposite 3+RADICAL 75
then you can divide like normal.
RADICAL = the radical sign then the 75 is in the sign
