The wind chill factor represents the equivalent air temperature at a standard wind speed that would produce the same heat loss a

s the given temperature and wind speed. One formula for computing the equivalent temperature is
W(t) = {■([email protected](10.45+10√v-v)(33-t)/[email protected](33-t) ) ┤ ■(if 0≤v<[email protected] 1.79≤v<[email protected] v≥20)


where v represents the wind speed (in meters per second) and t represents the air temperature . Compute the wind chill for an air temperature of 15°C and a wind speed of 12 meters per second. (Round the answer to one decimal place.) Show your work.

Those wind chill formulas are REALLY complex.
Attached are the formulas for wind chill (F and C) plus the OLD wind chill formula.
Here's a wind chill calculator I wrote. http://www.1728.org/windchil.htm

(I figured you might need all the help you can get.)

The rectangular top of a small box has dimensions of one 40 mm x 230 mm. How long in centimeters with a ribbon need to go all th
kozerog [31]

Answer:

540 mm

Step-by-step explanation:

Here we are given a rectangular box with dimensions of the top surface as 40 mm and 230 mm

We are asked to determine the measurement of the ribbon which may go all the way around the edge of it. Basically we are being asked the perimeter of the top surface. The perimeter is given as the

P=2 (l+w)

l = 230

w = 40

P=2(230+40)

P=2 x 270

P= 540

Hence we need 540 mm of ribbon  to go all the way around the edge of the top of the box.

Leni [432]

Answer:

Option A is correct.

Point T is not co-planar with points A, C and D

Step-by-step explanation:

Co-planar states that those which lies in the same plane.

Point A, C and D are lies in the Plane AEDC.

Since, this plane also contains points S and U.

Thus, point A, C , D , E, S  and U are co-planar

but point T does not lie in the plane  AEDC.

Therefore, point T is not co-planar with points A, C and D

Justin invested $7,300 in an account paying an interest rate of 1.5% compounded
lana [24]

Answer: 10.7 years.

Step-by-step explanation:

7,300 * (1 + 0.015)^x = 8,560 <=>

7,300 * 1.015^x = 8,560 <=>

1.015^x = 8,560 / 7,300 <=>

1.015^x = 1.1726 <=>

x = 10.694

To the nearest tenth:

x = 10.7 years
