What is the scale of a drawing in which a 9ft wall is 6cm long?

Mathematics

Orlov [11]3 years ago

Answer:

.022

Step-by-step explanation:

If you scale something you basically multiply it by something.  if you draw something at two times the scale, you are doubling it.  so 9 ft would be scaled up to 18 foot.  if you draw it at half the scale you cut it in half, so 9 would be 4.5.

The question is asking what do you multiply 9 feet by to get 6 cm.  Now, it's not just 9 to 6, but feet to centimeters.  A quick googling says the conversion is 1 foot = 30.48 centimeters.  so 30.48*9 gets us 9 feet is 274.32 cm.  So now we can simply find the scale factor between 274.32 cm to 6 cm.  Since it is decreasing we know it is going to be less than 1.  You basically use algebra though.  what do you multiply 274.32 by to get to 6?

274.32x = 6

x = 6/274.32

x = .022

So the scale factor is about .022

A track has lanes 1 meter wide. The turn radius of the inner lane is 25 meters. To make a fair race, the starting line in each l
Angelina_Jolie [31]
Assuming that there are N lanes and runners are running in the middle of each lane, 
width of each lane = (1/N) [m]turning of first lane = π×(R+(1/N)×(1/2))
turning of second lane = π×(R+((1/N)×(1/2))+(1/N))

you can get the difference in turning lane simply by subtracting turning of first lane from turning of second lane.  
If i worked the problem correctly, it should be π×(1/N) meter difference between each lane

ASAP!!!!!!!!!!!!!!!!!! Consider the point A=(1,3) and the line B, given by the equation y=2x-2 write an equation in slope-interc
vagabundo [1.1K]

Answer:

y = 2x+1 (slope-intercept form)

Step-by-step explanation:

From line B, y = 2x -2 and comparing with the general equation of line, y = mx +c, we have

m1 = 2

Parallelism rule states that m1=m2

Therefore, m2 = 2

Hence, the equation passing through point A(1,3) is

y-y1 = m2(x-X1)

y - 3 = 2(x-1)

y-3 = 2x-2

y = 2x-2+3

y = 2x+1 (slope-intercept form)
