Answer: 3¹/₃ boxes
Step-by-step explanation:
She made enough fudge to fill up 5 boxes then made 2/3 as much peanut butter.
To find out the number of boxes the peanut butter would fill, simply find out what is 2/3 of 5 boxes:
= 2/3 * 5
= 3.33 boxes
= 3¹/₃ boxes
Step-by-step explanation:
8x +6° +118° = 180° ( linear pair)
=> 8x = 180°-124°
=> 8x = 56°
=> x = 7°
hope this helps you.
Answer:
a) 
b) 
Step-by-step explanation:
Polar coordinates are represented as: 
, where 'r' is the length (or magnitude) of the line, and '
' is the angle measured from the positive x-axis.
in our case:
to covert the polar to cartesian:
we can plug in our values:
the Cartesian coordinates are:
(b) to convert (x,y) = (6.06,-3.5)
we'll use the pythagoras theorem to find 'r'
the angle can be found by:
to convert radians to degrees:
writing in polar coordinates:
First 1/5 is equivalent to 20% so to get 20% of both of them multiply by .2. so 400×.2=80 and 90×.2=18
Answer:
0 +256i
Step-by-step explanation:
According to Euler's formula, ...
(4 cis π/8)^4 = (4^4) cis (4×π/8) = 256 cis π/2 = 0 +256i
_____
"cis" is an abbreviation sometimes used for "cosine + i×sine". It simplifies writing the expression. Engineers sometimes simplify it further, writing 4∠(π/8) for the expression in this problem statement.
