(2.5 x 10^-4) (3 x 10^5)
= (2.5 x 3)(10^-4 x 10^5)
= 7.5 x 10^1
answer
7.5 x 10^1
Surely the answer would be 20 + 10h, though that isn't an option?
It grows 2h inches each week for 4 weeks, meaning (4 * 2h = 8h).
Then every 2 weeks after that, another 2h. Meaning in 6 weeks, a total of 10h.
Add this on to its original height of 20, gives us (20 + 10h)?
Answer:
a+b
Step-by-step explanation:
1/2(4a+6b) - 1/4(4a+8b)
= 4a/2 + 6a/2 - 4a/4 - 8a/4
=2a+3b-a-2b
=(2a-a)+(3b-2b)
=a+b
Answer:
Step-by-step explanation:
The axis AB is passing through the center O as it hold the diameter.
OC⊥AC as tangent is perpendicular to radius.
<u>∠BOC is the central angle and is of same measure as intercepted arc BC:</u>
<u>∠BOC is exterior angle to ΔAOC, hence is equal to sum of non-adjacent interior angles:</u>
- m∠BOC = m∠OAC + m∠OCA
- 102° = m∠1 + 90°
- m∠1 = 102° - 90°
- m∠1 = 12°
