If you were to measure a straight line from New York to Hong Kong it would measure 12.6 cm. If the scale of the map says that 30

00 miles are 3.2 cm, what is the distance between New York and Hong Kong in miles?

WE can solve it by ratio and proportions

Let the distance be x

\\ \sf\longmapsto \dfrac{x}{12.6}=\dfrac{3000}{3.2}

\\ \sf\longmapsto 3.2x=3000(12.6)

\\ \sf\longmapsto 3.2x=37800

\\ \sf\longmapsto x=\dfrac{37800}{3.2}

\\ \sf\longmapsto x=11812.5mi

Answer:

  • 11812.5 miles

Step-by-step explanation:

<u>Given:</u>

  • 3000 miles → 3.2 cm
  • x miles → 12.6 cm

<u>Solve for x by cross-product:</u>

  • 3.2x = 3000*12.6
  • x = 37800/3.2
  • x = 11812.5 miles

Lin is running on a track. Lin runs 5 laps around a track in 6 minutes. How many laps per minute is that? (Find both Unit Rates)
grandymaker [24]
They got the 1.2 minutes by taking the total number of minutes (6) and dividing them by the number of laps run (5). So 6 divided by 5 gives you the 1.2.

A trough of water is 20 meters in length and its ends are in the shape of an isosceles triangle whose width is 7 meters and heig
Vaselesa [24]

Answer:

a) Depth changing rate of change is 0.24m/min, When the water is 6 meters deep

b) The width of the top of the water is changing at a rate of 0.17m/min, When the water is 6 meters deep

Step-by-step explanation:

As we can see in the attachment part II, there are similar triangles, so we have the following relation between them \frac{3.5}{10} =\frac{a}{h}, then a=0.35h.

a) As we have that volume is V=\frac{1}{2} 2ahL=ahL, then V=(0.35h^{2})L, so we can derivate it \frac{dV}{dt}=2(0.35h)L\frac{dh}{dt} due to the chain rule, then we clean this expression for \frac{dh}{dt}=\frac{1}{0.7hL}\frac{dV}{dt} and compute with the knowns \frac{dh}{dt}=\frac{1}{0.7(6m)(20m)}2m^{3}/min=0.24m/min, is the depth changing rate of change when the water is 6 meters deep.

b) As the width of the top is 2a=0.7h, we can derivate it and obtain \frac{da}{dt}=0.7\frac{dh}{dt}  =0.7*0.24m/min=0.17m/min The width of the top of the water is changing, When the water is 6 meters deep at this rate
