Answer:

1 cm^2 = 100 mm^2

9 cm^2 = 900 mm^2

5.2 cm^2 = 520 mm^2


1 dm^2 = 100 cm^2

17 dm^2 = 1700 cm^2

4.3 dm^2 = 430 cm^2


1 m^2 = 10000 cm^2

7 m^2 = 70000 cm^2

2.5 m^2 = 25000 cm^2


1 km^2 = 1000000 m^2

50 km^2 = 50000000 m^2

8.5 km^2 = 8500000 m^2

Step-by-step explanation:

1 cm = 10 mm

1 cm^{2} = 10×10 mm^{2} = 100 mm^{2}

9 cm^{2} = 9×100 mm^{2} = 900 mm^{2}

5.2  cm^{2} = 5.20×100 mm^{2} = 520 mm^{2}


1 dm = 10 cm

1 dm^{2} = 10×10 cm^{2} = 100 cm^{2}

17 dm^{2} = 17× 100 cm^{2} = 1700 cm^{2}

4.3 dm^{2} = 4.3 × 100 cm^{2} = 430 cm^{2}


1 m = 100 cm

1 m^{2} = 100×100 cm^{2} = 10000 cm^{2}

7 m^{2} = 7×10000  cm^{2} = 70000 cm^{2}

2.5 m^{2} = 2.5×10000 cm^{2} = 25000 cm^{2}


1 km = 1000 m

1 km^{2} = 1000×1000 m^{2} = 1000000 m^{2}

50 km^{2} = 50×1000000 m^{2} = 50000000 m^{2}

8.5 km^{2} = 8.5×1000000 m^{2} = 8500000 m^{2}

Twice the difference of a number and 5 is 2.<br> Use the variable W for the unknown number
Kitty [74]
Hey there!

The difference of a number, w, and 5 will be represented by (w – 5). Twice this would simply multiply this expression by 2, making it 2(w – 5). Finally, just set this expression equal to 2. Your equation is 2(w – 5) = 2. 

To solve this, expand the two to the terms in parentheses. Then, solve the rest of the way as you would normally, using addition, subtraction, multiplication, or division to cancel out and move around terms. Remember, what you do on one side must be done to the other!

2(w – 5) = 2
(2*w – 2*5) = 2
(2w – 10) + 10 = (2) + 10
(2w) ÷ 2 = (12) ÷ 2
w = 6

Hope this helped you out! :-)

A ceramics workshop makes wreaths, trees, and sleighs for sale at Christmas. A wreath takes 3 hours to prepare, 2 hours to paint
Vanyuwa [196]
If all things can be made at the same time, then it would look something like this(all numbers should be rounded down):

127 of Prep: Wreath:127/3 = 42 prepped
127 of Prep: Tree:127/14 = 9 prepped
127 of Prep: Sleigh:127/4 = 31 prepped

104 of Painting: Wreath:104/2 = 52 painted(but because only 42 were prepped, your number will be 42 still)
104 of Painting: Tree:104/3 = 34 painted(As stated above, but with only 9)
104 of Painting: Sleigh:104/17 = 6 painted(this number will overwrite the number of prepped sleighs as only 9 could be painted in the allotted time.)

133 of Firing: Wreath:133/9 = 14 ready to go
133 of Firing: Tree:133/4 = 33(but only nine were painted so the number ready to go is 9) 
133 of Firing: Sleigh:133/7 = 19(but only 6 are ready to go)

Final Results: Wreath - 14
                       Tree - 9
                      Sleigh - 6
