.0625 is the answer. Hope this helped
It's 28/8 but if you want to simplify its 3.5
Answer:
$4.80
Step-by-step explanation:
6 oranges for 1.80
sp 6 divided by 1.80 comes out to 0.3 per orange
0.3 times 16 comes out to 4.80
therefor $4.80
Answer:
4
Step-by-step explanation:
The area is 16, and you know that it's 2 sides u need to multiply
The perimeter is 16, and you know that you need to add up all the sides
So....
A = b * h
A = 4 * 4
A = 16 CORRECT
And....
P = S + S + S + S ( s = sides)
P = 4 + 4 + 4 + 4
P = 16 CORRECT
Hope this helped!
Have a supercalifragilisticexpialidocious day!
