Answer:
24,53cm²
Step-by-step explanation:
rectangle area=length×width=7×3
=21cm²
circle area=1/2Π r²
=1/2×3.14×1.5×1.5
=3.5325cm²
add the two areas
21+3.53=24,53cm²
Answer:
30 and -30 and if that doesn’t work then maybe try -30 first and 30 next
Knowing the amount doubles every 30 days, we'll have to find how many times it'lll double in the 210-day time frame:
210 / 30 = 7
It doubles 7 times. If we were to write a rough, not worked on expresion representing that, knowing the starting population was of 20, we would write:
(((((((20 * 2) * 2) * 2) * 2) * 2) * 2) * 2) = 2560 rabbits
Hope it helped,
Happy homework/ study exam!

50/0.1=500
double check, 500x0.1=50
