If a concrete mix contains 1-1/2 cubic feet of gravel, 1/2 cubic foot of water,

Karolina [17]

Answer:

The correct answer is "50%".

Step-by-step explanation:

The given values are:

Gravel,

= $(1-\frac{1}{2} )$

Water,

= $\frac{1}{2}$

Cement,

= 1

Sand,

= 2

Now,

The total mixture will be:

= $Gravel+Water+Cement+Sand$

By substituting the values, we get

= $(1-\frac{1}{2} )+\frac{1}{2} +1+2$

= $\frac{1}{2} +\frac{1}{2} +1+2$

= $4 \ cubic \ feet$

hence,

The percentage of sand will be:

= $\frac{Sand}{Total}\times 100$

= $\frac{2}{4}\times 100$

= $50$ %

Need the a answer for this

FinnZ [79.3K]

Answer:

Given expression:

$\dfrac{14a^4b^6c^{-10}}{8a^{-2}b^3c^{-5}}$

Separate the variables:

$\implies \dfrac{14}{8} \cdot \dfrac{a^4}{a^{-2}} \cdot \dfrac{b^6}{b^3} \cdot \dfrac{c^{-10}}{c^{-5}}$

Reduce the first fraction:

$\implies \dfrac{7}{4} \cdot \dfrac{a^4}{a^{-2}} \cdot \dfrac{b^6}{b^3} \cdot \dfrac{c^{-10}}{c^{-5}}$

$\textsf{Apply Division Property of Exponents rule} \quad \dfrac{a^b}{a^c}=a^{b-c}:$

$\implies \dfrac{7}{4} \cdot a^{4-(-2)} \cdot b^{6-3} \cdot c^{-10-(-5)}$

$\implies \dfrac{7}{4} \cdot a^{6} \cdot b^{3} \cdot c^{-5}$

$\textsf{Apply Negative Property of Exponents rule} \quad a^{-n}=\dfrac{1}{a^n}$

$\implies \dfrac{7}{4} \cdot a^{6} \cdot b^{3} \cdot \dfrac{1}{c^5}$

Therefore:

$\implies \dfrac{7a^6b^3}{4c^5}$
