Answer:
Step-by-step explanation:
in complex number land there are two distict parts real.. the first number and imaginary.. the second number with the i
if your problem really only has a 7 and an i in it.. then it looks like below
7 * i = 7i
but..I suspect you just left out a bit of the problem.. repost .. i'll answer it again if the problem is different that what you posted already :)
Answer:
t≅13.33h
Step-by-step explanation:
Adam (A) works at constant rate of 50tiles/h
Briana (B) works at constant rate of 55tiles/h, this means that A=50 tiles per hour and B=55 tiles per hour, then A+B = 105tiles/h together, but the floor consists of 1400tiles, so if 105 tiles are installed in one hour, then 1400 tiles in how long they will be installed?
t = 1400tiles*h/105tiles≅ 13.33 h
All options are incorrect
the correct answer is
Answer:
3210cm³
Explanation:
volume of a cylinder = πr²h
where r= d/2 = 16/2= 8cm
h= 16cm
.: V= πr²h
= 3.14 × 8² × 16
= 3.14 × 64 × 16
= 3215.32 cm³
=3210cm³ (rounding off to nearest tenth.)
