how do you solve this problem. there are approximately 2.1 million deaths per year in country A. Express this quantity as deaths
slamgirl [31]
Well... we know that... there are 365 days in a year, unless is a leap-year, but we'll use 365 anyway

and each day has 24hrs, each hr has 60 minutes

so. let us use those ratios

\bf 2.1million\iff 2.1E6\iff 2,100,000\qquad thus&#10;\\\\\\&#10;\cfrac{2100000\ deaths}{1\ year}\cdot \cfrac{1\ year}{365\ day}\cdot \cfrac{1\ day}{24\ hr}\cdot \cfrac{1\ hr}{60\ minute}

so.. multiply and simplify, cancelling out any like-units atop and bottom

notice, all we do, is use the ratios, in a way, that if we need one unit to be changed, we flip the ratio

for example, to toss away "year" unit, since in the first fraction is at the bottom, then we put it on the top on the ratio, year/year  = 1, effectively cancelling the unit

wlad13 [49]

Answer:

Building B, it is around 16 35 feet taller than building A ( C )

Step-by-step explanation:

<u>Calculating  the height of Building A </u>

Height = opposite ( ? )

∅ = 73°

base/adjacent  = 30 ft

∴ Height = Tan 73° * base

               = 3.2709 * 30 =  98.127 ft

<u>Calculating the height of building B </u>

∅ = 73°

base/adjacent  = 35 ft

∴ height = Tan 73° * base

              = 3.2709 * 35 = 114.4815

Therefore we can say Building B is Taller by approximately 16.35 feet
