Step-by-step explanation:
a square has 4 identical sides.
so, when you have to "walk" around the perimeter of a square you have to go 4 times the same distance.
therefore
20 = 4×side length
side length = 20/4 = 5 in
it is a 5 in × 5 in square.
FYI a rectangle has 2 pairs of sides that are equally long inside their pair.
and so you have in this case a perimeter of
2×6 + 2×4 = 12 + 8 = 20 in

Hello!
The histogram summarizes the amount of sugar in organic snacks. (mg)
Y-axis shows the number of snacks
X-axis shows the amount of sugar per snack
The first column of the histogram show that 2 snacks contain sugar between 220 and 224 mg of sugar.
The second column shows that about 3 snacks have between 224 and 228 mg of sugar.
The third column shows that 8 snacks have between 228 and 232 mg of sugar.
The fourth column shows that 12 snacks have between 232 and 236 mg of sugar.
The fifth column shows that 11 snacks have between 236 and 240 mg of sugar.
The sixth column shows that 3 snacks have between 240 and 244 mg of sugar.
The seventh column shows that 2 snacks have between 244 and 248 mg of sugar.
The total of observations is 2+3+8+12+11+3+2= 41 snacks.
I hope this helps!

The day of the month that was 75% of the pond algae-free is: on day 28 or third day.
<h3>75% of the pond algae-free</h3>
Since we were told the algae doubled every day until it was covered in algae on day 30 of the month.
Hence:
Day 30 (First day)= It was 100% covered.
Day 29 (Second day)=It was 50% covered.
Day 28 (Third day )=it was 25% covered, which will be the same as 75% pond algae-free.
Therefore the day of the month that was 75% of the pond algae-free is: on day 28 or third day.

amount of algae covering the Smith's backyard pond doubled every day until it was completely covered in algae on day 30 of the month. On what day of that month was 75% of the pond algae-free?
2(2h)+2h=p
p is perimeter
2h is base which is twice and the second 2h is there because the equation for perimeter is 2b+2h=p
