HELPP I need help solving these metric system operations!!! ASAPP 1) 0.026m ___ 1480mm - 20mm = 1.486m

2) 0.12kg x 10,000mg - g = 1120g

3)7000mL/0.35L ___ 5mL = 0.1L

4) 6000mm + 300m x 2000mm = m

5) 444g/111g ___ 5000mg = 20,000mg

6) ___mL x 30mL - 7L =
500mL

7) 90m ___ 40m/10,000mm = 86m

8) 0.6kg x 300g/90g = ___g

9)3600mm ___ 3m + 10m = 10,600mm

10) 3000mL + L/4L = 6000mL

I just need the blanks filled in :)

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
