I think it would be conditional, because B depends on A. Of A is false, then B isn’t possible, making it conditional.

Option D:

$\frac{25 a^{9} b^{10} }{6 }$ is equivalent to the given expression.

Solution:

Given expression:

$$\frac{(5 a b)^{3}}{30 a^{-6} b^{-7}}$

To find which expression is equivalent to the given expression.

$$\frac{(5 a b)^{3}}{30 a^{-6} b^{-7}}$

Using exponent rule: $(ab)^m=a^mb^m$

$$=\frac{5^3 a^3 b^{3}}{30 a^{-6} b^{-7}}$

Using exponent rule: $\frac{1}{a^{m}}=a^{-m}, \quad \frac{1}{a^{-m}}=a^{m}$

$$=\frac{125 a^3 b^{3}a^{6} b^{7}}{30 }$

$$=\frac{125 a^3 a^{6} b^{3} b^{7}}{30 }$

Using exponent rule: $a^{m} \cdot a^{n}=a^{m+n}$

$$=\frac{125 a^{3+6} b^{3+7} }{30 }$

$$=\frac{125 a^{9} b^{10} }{30 }$

Divide both numerator and denominator by the common factor 5.

$$=\frac{25 a^{9} b^{10} }{6 }$

$$\frac{(5 a b)^{3}}{30 a^{-6} b^{-7}}=\frac{25 a^{9} b^{10} }{6 }$

Therefore, $\frac{25 a^{9} b^{10} }{6 }$ is equivalent to the given expression.

Hence Option D is the correct answer.

What is 5x+ (2 + x). A .8x B. 6x + 2 C. 7x D. 5x + 2

vovikov84 [41]

The answer would be B) 6x + 2.

5x + 2 + x (simplify)

(5x + x) + 2 (gather like terms)

6x + 2 (simplify).

A new swimming pool is an 18 feet wide and 36 feet long rectangle with varying depths. If 1 cubic foot= 7.48 gallons of water, h

Blababa [14]

Answer:

gallons of water will be needed to fill the pool 19388.16 gallons

Step-by-step explanation:

given data

Length of rectangular pool = 36 feet

Width of rectangular pool = 18 feet

1 cubic foot = 7.48 gallons water

solution

we consider here Depth of rectangular pool = 4 feet

so Volume of the pool = Length × Width × Depth ..............................1

put here value

Volume of the pool = 36 × 18 × 4

Volume of the pool = 2592 cubic feet

and

1 cubic feet = 7.48 gallons

so 2592 cubic feet will be

2592 cubic feet = 7.48 × 2592

2592 cubic feet = 19388.16 gallons
