C. Because 8x24=192 and then you have to do 192x2.25 which gives you the answer 432!

The answer is C or 432. The steps towards the answer are 2.25 or 2 1/4 times 24 to find out how many boxes are being donated then multiply that by the number of crayons in each box. 2.25x24= 54 54x8=432

3.4 in word form and expanded form
bagirrra123 [75]
<span><span><u>Answer</u>
3.4 in words is: Three and four tenths
3.4 in expanded form 3+4/10

</span><span><u>Explanation</u>
Decimal points are fractions whose denominator is 10 or a power of 10. To write a decimal point in words we must be able to identify the place value of every digit.
3.4
3 is a whole number and its place value is ones and the place value of 4 is tenth.
So, 3.4 in words is: Three and four tenths
3.4 in expanded form 3+4/10</span></span>

A large stand of fir trees occupies 24 hectares. The trees have an average density of 1 tree per 20m squared. A forester estimat
Leona [35]

Answer:

The yield of the stand if one-tenth of the trees are cut is 360000 board-feet.

Step-by-step explanation:

First, let is find the total amount of fir trees that occupies the area of 24 hectares. (1 hectare = 10000 square meters)

n = \sigma \cdot A

Where:

\sigma - Surface density, measured in trees per square meter.

A - Total area, measured in square meters.

Given that \sigma = \frac{1}{20}\,\frac{tree}{m^{2}} and A = 24\,h, the total amount of fir trees is:

n = \left(\frac{1}{20}\,\frac{trees}{m^{2}}  \right)\cdot (24\,h)\cdot \left(10000\,\frac{m^{2}}{h} \right)

n = 12000\,trees

It is known that one-tenth of the tress are cut, whose amount is:

n_{c} = 0.1 \cdot n

n_{c} = 0.1 \cdot (12000\,trees)

n_{c} = 1200\,trees

If each tree will yield 300 board-feet, then the yield related to the trees that are cut is:

y = S\cdot n_{c}

Where:

S - Yield of the tress, measured in board-feet per tree.

n_{c} - Amount of trees that will be cut, measured in trees.

If n_{c} = 1200\,trees and S = 300\,\frac{b-ft}{tree}, then:

y = \left(300\,\frac{b-ft}{tree} \right)\cdot (1200\,trees)

y = 360000\,b-ft

The yield of the stand if one-tenth of the trees are cut is 360000 board-feet.
