Find the length of BC

prohojiy [21]

Answer:

<h3>The answer is option A</h3>

Step-by-step explanation:

To find the length of BC we use tan

tan ∅ = opposite / adjacent

From the question

AC is the opposite

BC is the adjacent

So we have

tan 61 = AC / BC

tan 61 = 47/BC

BC = 47/tan 61

ASAP A virus has a volume of approximately 4.7x10^-14 cubic centimeters. Calculate the estimated volume of 4.1x10^16 viruses.

Afina-wow [57]

Hence, the volume of 4.1x10^16 viruses is:

$1.927*10^3\ cm^3$

Further explanation:

<u>Given</u>

$Volume\ of\ one\ virus=4.7*10^{-14}\ cm^3$

$Volume\ of\ 4.7*10^{16}\ viruses=?$

To find the volume of given viruses, volume of one virus will be multiplied to the number of viruses

So,

$Volume\ of\ 4.1*10^{16}\ viruses= (4.7*10^{-14})*(4.1*10^{16})$

When two numbers with exponents have to be multiplied, their powers are added and number are multiplied.

$V=(4.7*4.1)*(10^{-14+16})\\=(19.27)*(10^2)\\=19.27*10^2\\=1.927*10*10^2\\=1.927*10^{1+2}\\=1.927*10^3$

Hence, the volume of 4.1x10^16 viruses is:

$1.927*10^3\ cm^3$
