(3/5 - 1/4)x = 350 where x = capacity of the basin
(7/20)x = 350
x = (350 *20) / 7 = 1000 mls Answer
Answer:
last choice
Step-by-step explanation:
sin(theta) is positive
tan(theta)=sin(theta)/cos(theta) is negative
If sin(theta) is positive and tan(theta) is negative, then cos(theta) is negative because +/-=-
So we are looking for the quadrant where sine is positive and cosine is negative or when x is negative and y is positive.
This is in quadrant 2 so our angle theta is between 90 and 180 degrees.
Parallel lines add to 180 therefore x is 146
Area of the shaded region = 80 in²
Explanation:
The outer diagram is a square
Area of the square = length × length
length = 12in
Area of the square = 12in × 12in
Area of the square = 144in²
There are 3 smaller squares in each row and column:
The length in each row and colum = 12
the length o fone small box = 12/3 = 4
Area of the smaller box = 4in × 4in = 16 in²
There are 4 boxes unshaded
Area of 4 unshaded boxes = 4 × 16 in² = 64in²
Area of the shaded region = Area of the outer box - area of the unshaded boxes
Area of the shaded region = 144 - 64
Area of the shaded region = 80 in²
