Answer:

7.8*10^7

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

An artist uses a 3-foot piece of wood to carve statues she uses 1/6 foot pieces of wood for each statue how many statues can be

Alexxandr [17]

Answer:

Step-by-step explanation:

Dimension of piece of wood = 3 ft

Dimension of piece of wood used for one statue = $\frac{1}{6}$ ft

To find:

Number of statues that can be made from all the wood ?

Solution:

To find the total number of statues that can be carved from the given piece of wood, we need to divide the dimensions of given piece of wood with the piece required to carve one statue.

Formula:

$\dfrac{a}{\frac{b}{c}} = \dfrac{a\times c}{b}$

Number of statues that can be made:

$\dfrac{3}{\frac{1}{6}}\\\Rightarrow \dfrac{3\times 6}{1}\\\Rightarrow \bold{18}$

Therefore, 18 number of statues can be made.
