How do i get aquantum ml 29032 scale manager manual?


A Scale Manager kit comprises of the following:
  • One computerised electronic water descaler
  • One 12 volt power supply, cable length 1.8m - 6?
    Optional when ordering, 5m - 16½' power supply extension lead
  • Antenna cable with red plug
  • Antenna cable with black plug
  • Five plastic cable ties (1 spare)
  • One attachable black antenna plug
  • One attachable red antenna plug
Please Note: Ensure antennae cables do not come into contact with each other
  • The gap between the coils must be in excess of 60mm - 2½" no upper limit
  • Coils require a minimum of 50mm - 2? each side of uninterrupted straight pipe
  • Direction of coils is essential - see over
  • Ideally a 125mm + (5?+) straight run of pipe is required for each antenna coil
  • Direction of Water Flow is immaterial
  • Connect red plugs to red sockets and black to black
  • Scale Manager is effective on all pipes (copper, plastic, lead, steel etc)
  • Performance is not impaired if the pipe is painted
  • The Control Unit can be fitted at any angle or plane
  • A 13-amp socket is required for the power supply
The ideal location to install Scale Manager is near the entry point of the rising main, before any junctions. The antennae coils operate independently and can be positioned on separate pipes should you not have an uninterrupted pipe run of 250mm - 10?. Should the inlet pipe T off within 125mm - 10? of the stopcock, position the coils as fig 1 overleaf. If the inlet pipe available is over 125mm - 5? but under 250mm - 10? position as fig 2 overleaf.
The antennae coils require a minimum gap between them of 50mm - 2?. It is also necessary that the coils are at least 40mm -1½" from elbows and junctions.

Is it possible to calculate factors using a TI-30x IIS


I believe factors can be calculated on any basic calculator.

Starting with 1, increasing by 1 until you get to square root (number) + 1

Let's do an example.

28
square root (28)+1 = 6
Factors
1, 28/1=28
2, 28/2=14 14*2 - 28 = 0 (when you divide, you get no decimal)
3, 28/3=9.33333 - not a factor - doesn't go in evenly
4, 28/4 =7
5, 28/5=5.6 - not a factor - doesn't go in evenly
6, 28/6=4.66666 - not a factor
So now we can list our factors - 1, 28, 2, 14, 4, 7
Putting them in order, we get 1, 2, 4, 7, 14 and 28.

Good luck,

Paul

Regular pentagon QRSTU has a side length of 12 cm and an area of about 248 square cm. Regular pentagon VWXYZ has a perimeter of 140 cm. Find the area of VWXYZ. Round to the nearest tenth.


Find the scaling ratio
Perimeter of first pentagon is 12*5=60 cm
Scale factor (2nd/first)=140/60 =7/3
Ratio of areas varies as the square of the scale factor for the lengths
Area of second / area of first =(7/3)^2 =49/9
Area of second pentagon =248 *(49/9) cm^2
Finish the calculation.

Regular pentagon QRSTU has a side length of 12 cm and an area of about 248 square cm. Regular pentagon VWXYZ has a perimeter of 140 cm. Find the area of VWXYZ. Round to the nearest tenth.


The two pentagons are similar. If k is the scale factor for the lengths, the ratio of the areas is k^2.
Pent 1 side =12 cm
Pent 2 side =140/5 =28 cm
Scale factor (larger over smaller) is k=28/12=7/3
Area of Pent_2= (49/9)*Area of Pent_1
Your answer should be C.

The new patio


The figure are similar, corresponding sides are proprtional
L1/L'1=L2/L'2= ... =k , the scale factor for lengths.
However, if scale factor for lengths is k, the ratio of area is k^2 find
Scale factor
Use the given area to find the proportionality factor then use it the ratio of length to find the missing distance between the parallel sides.
Area of new /Area of old=360/250=36/25=k^2
k=SQRT(36/25)=6/5

Ratio of lengths =k=6/5
Distance between parallel sides of new patio/Distance between parallel sides of old patio=6/5
Distance between parallel sides of new patio= (6/5)*12.5=15

The distance between the parallel sides of the new patio is 15 feet.

How are you supposed to know if two shapes are similar if there aren't on a grid.


Use a ruler to measure the lengths of the sides and a protractor to measure the angles. The scale factor is the lengths of one divided by the lengths of the other.

How do you add pictures to the photo fram:


Use PhotoFiltre free photo editor program to edit your pictures.
You may download it from the below link.

http://www.4shared.com/file/gqHN4jSz/pf-setup-en.html

1. Photos should be in .jpeg format.
2. It is better to scale your photos with the above editor to 800x600 pix.
3. Prepare your pictures in a PC using PhotoFiltre. Scale all the pictures.
4. Transfer your pictures from PC to a USB Flash Disk (Memory Bar)
5. Plug USB Flash Disk to your Photo Frame.
6. Probably your photo frame will ask to transfer your pictures from flash disk to internal memory. Accept this and by pressing enter/OK/Set (Any button that changes from one product to another.)

I think it helps.
