The answer is supposed to be x=43 not x=42 because x=36+7 is equal to 43.
Answer:
9.5 * 10^-2 mm
Step-by-step explanation:
To find the total thickness, we proceed to add the two thickness that we have
Mathematically, this will be;
0.025 mm + 7 * 10^-2 mm
7 * 10^-2 mm = 0.07
So we have;
0.025 mm + 0.07 mm = 0.095
In scientific notation, this is 9.5 * 10^-2 mm
If 70% lay eggs, that leaves the remaining 30% to give live birth. 2700(0.30) = 810 species
Answer:
r = 8
Step-by-step explanation:
The common ratio r of a geometric sequence is
r = 
= 
= ..... = 
Then
r = 
= 
= 8
-.12 to both sides
49.46+.2x = 55.96
-49.46 to both sides
.2x = 6.5
Divide by .2 on both sides
X= 32.5
