Which is the best estimate for (8.9x10^8)/(3.3x10^4) written in scientific notation? a. 3x10^2 b. 6x10^2 c. 3x10^4 d. 6x10^4

Option C

Step-by-step explanation:

The given expression is

Now we have to solve this.

= 2.70 × 10⁽⁸⁻⁴⁾

= 2.70 × 10⁴

≈  3 × 10⁴

Therefore, Option C is the answer.

1/3 + 1/5 = 8/15.

step-by-step explanation:

hope it

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
