Simplify: 7√(1/3) + 2 1/3√(1/3) + 3√(147)​
LiRa [457]

Step-by-step explanation:

7 √(1/3) - 2 1/3 √(1/3) +3√147

→7(1/√3) - (7/3)(1/√3) +3√(3×7×7)

→ (7/√3) - (7/3√3) +3×7√3

→ (7/√3) - (7/3√3) + 21√3

On Rationalising the denominators then

→ [ 7√3/(√3×√3)]-[7√3/(3×√3×√3) +21√3

The Rationalising factor of√3 =√3

→ (7√3/3)-[7√3/(3×3)]+21√3

→ (7√3/3)-(7√3/9)+21√3

LCM of 3 and 9 = 9

→ [(3×7√3)-(7√3)+(9×21√3)]/9

→ (21√3-7√3+189√3)/9

→[(21-7+189)√3]/9

→ [(210-7)√3]/9

→ 203√3/9 Ans.

Hope this helps.

What is a better deal 56/25 or 32.05/15
saul85 [17]

We are given fractions: \frac{56}{25} \ or \ \frac{32.05}{15}.

Let us convert those both fractions in decimals only to get the better deal.

For first fraction 56/25, if we divide 56 by 25, we get

56 ÷ 25 = 2.24 decimal value.

And for second fraction 32.05/15 if we divide 32.05 by 15, we get

32.05 ÷ 15 = 2.14 (approximately).

2.14 is lesser value, therefore 2.14 is better deal than 2.24.

And finally we could say 32.05/15 is better deal  than 56/25.

A rock falls from rest a vertical distance of 0.72 meters to the surface of a planet in 0.63 seconds. The magnitude of the accel
Andreas93 [3]

Answer:

3.63 meter/sec²

Step-by-step explanation:

When a rock fall from a height h with initial velocity u and the rock reaches the surface in t seconds the expression that represents this is

h = 4t + \frac{1}{2} gt²

Where g is the acceleration due to gravity

Here h = 0.72 meters

        u = 0

        t = 0.63 seconds

from the given formula

0.72 = 0 ×(0.63) + \frac{1}{2} g(0.63)²

0.72 = \frac{1}{2} g(0.63)²

g = \frac{2\times0.72}{(0.63)^2}

= 3.63 meter/sec²
