which of the following statements are equivalent to the ratio 10: 3? choose all that apply

1. 28 days to 6 days
2. 120 meters to 8000 meters
3. 2000 pounds to 600 pounds
4. 300 seconds to 20 seconds
5. 250 cents to 75 cents

3. 2000 pounds to 600 pounds and 5. 250 cents to 75 cents

Step-by-step explanation:

The ratio is 10:3 so just multiply the first number by ten and the and the second by 3 to see if it matches

ex. 10 x 200= 2000    3 x 200= 600

10 x 25=250   3 x 25= 75

I hope this makes sense, this is kinda hard to physically explain.

Its 3 and 5.

Step-by-step explanation:

Simplifying:-

1. 28:6 = (28/2):(6/2) = 14 : 3   so its not 1.

2.  120:8000 =  (120/40) : (8000/40) = 3 : 200 . No.

3. 2000 : 600 = 1000 : 300 = 10:3.   Yes.

4.  300: 20 =(300/20):(20/20) = 15:.1  No.

5. 250 : 75  =  (250/25) : (75/25) = 10:3  Yes.

b, i believe, but not sure.

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
