Answer:
64 fish
Step-by-step explanation:
If there is 1/4 fish with black stripes and its a total of 16 then you have to multiple 16 times 4 because theres 4 groups. so 16 times 4 is 64.
3(21+15) is 3*21 and 3*15 which equal 63+45 which is 108 dollars
Answer:
77.93
Step-by-step explanation:
#We can simply read off the x,y coordinates directly from the graph.
![i. [1,8]\\\\ii. [4,5]\\\\iii. \ [14,21]\\\\iv.\ \ \ [17,18]](https://tex.z-dn.net/?f=i.%20%5B1%2C8%5D%5C%5C%5C%5Cii.%20%5B4%2C5%5D%5C%5C%5C%5Ciii.%20%5C%20%5B14%2C21%5D%5C%5C%5C%5Civ.%5C%20%5C%20%5C%20%5B17%2C18%5D)
#we know that a rectangle has pair of two equal sides. To calculate the area, we determine the dimension of any un-equal two sides:
#Using Pythagorean Theorem:

We can therefore calculate area as:

Hence, the area of the rectangle is 77.93
