(6.6*10^4) (7*10^3) can someone me i'm so confused! 12pts.

462,000,000

10^4= 10,000

10,000*6.6=66,000

10^3=1,000

1,000*7=7,000

Okay.

10^4 = 10*10*10*10 = 10,000

10^3 = 10*10*10 = 1,000

6.6*10,000 = 66,000

7*1,000 = 7,000

66,000*7,000 = 462,000,000

If you are still confused, I can try to explain further.

step-by-step explanation:

d

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
