Assume that y varies directly with x. if y=1/4 when x=1/8, find x when y=3/16

3/32

Step-by-step explanation:using k as constant of proportionality,

y=kx

1/4=1/8k

k=0.25/0.125=2

When y =3/16

x=y/k=(3/16)/2

x=3/32

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
