An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms. 3/4 of this weight is metal and the rest is wood.

Troyanec [42]

Answer:

Given is a sculpture that is built up of metal and wood, and the weight of this sculpture is 14.9 kilograms.

It says that three-fourth of the total weight is metal and says to find the weight of wooden part.

We can find the weight of metal part and then subtract it from the total weight to calculate the answer.

Total weight = 14.9 kilograms.

Metal part = three-fourth of total weight =

Wooden part = 14.9 - 11.175 = 3.725 kilograms.

Hence, the wooden part is 3.725 kilograms.

Work out in a standard form. <br>A) 2.1x 10^-5 ÷7 x 10^-2

EleoNora [17]

$\huge\underline{\underline{\boxed{\mathbb {SOLUTION:}}}}$

<h3>Given:</h3>

▪ $\longrightarrow \sf{\dfrac{2.1 \times {10}^{5} }{7 \times {10}^{ - 2} } }$

First, rewrite the numerator in such a way that the coefficient 2.1 becomes 21:

$\small\longrightarrow \sf{\dfrac{21 \times {10}^{ - 6} }{7 \times {10}^{2} } }$

Divide the coefficient:

$\small\longrightarrow \sf{21 \div 7=3}$

Divide the base by subtracting the exponents of the base 10.

$\small\longrightarrow \sf{-6(-2) \Longrightarrow -6+2=-4}$

$\leadsto$ Hence, the quotient of the given expression has a coefficient of 3 and the exponent of the base 10 is -4.

$\small\longrightarrow \sf{3 \times 10^{-4}}$

$\huge\underline{\underline{\boxed{\mathbb {ANSWER:}}}}$

$\large \bm{The \: \: quotient \: \: is \: \: 3 \times {10}^{ - 4} .}$
