9514 1404 393

Answer:

√51 ≈ 7.141
1313/9900 ≈ 0.133
∛971 ≈ 9.902

Step-by-step explanation:

The usual rules of rounding apply. If the digit in the 4th decimal place is 5 or more, then 1 is added in the 3rd decimal place. The roots are found using your calculator. The first 4 digits of the repeating decimal are clearly visible already.

a) √51 ≈ 7.141428... ≈ 7.141

b) 0.1326_26 ≈ 0.133

c) ∛971 ≈ 9.90238... ≈ 9.902

_____

<em>Additional comment</em>

The repeating decimal is equivalent to the fraction 1313/9900.

The ratio of enlisted men to officers in a division is 25 to 1.

9966 [12]

The answer is 40.

1000/25 will give you the new ratio

Simple way of thinking about it

25 enlisted men = 1 officer
1000enlisted men = X officer

Cross multiply (25 by X officer and the 1 officer by the 1000)

25x = 1000

X= 40.

alexdok [17]

The equation is:
h ( t ) = - 16 t² + 60 t + 3
The toy rocket will reach the ground when: h ( t ) = 0
- 16 t² + 60 t + 3 = 0
$t _{12} = \frac{-60+/- \sqrt{3600+192} }{-32}$
t 1 = - 0.05
t 2 = 3.8
