Answer:
Between 2 1/2 and 3 ounces
Step-by-step explanation:
Since 1/3 is lower than 3/4, 5 1/3 - 2 3/4 must be lower than 3, but higher than 2.
So, we can eliminate C and D.
A's range is too small, so we can select B.
Here is a trick that not a lot of people know
(# of terms)*(first+last)/2
(in case you don't know, * means multiply and / means divide)
It doesn't. 16/6 = 2 4/6 or 2 2/3
Answer:
7
Step-by-step explanation:
4 / 2 = 2, so they are proportional, and the perimeter of the smaller figure will be one half of the perimeter of the larger figure.
(4+2+5+3)/2 = 14/2 = 7
