Answer:
2 and 5
Step-by-step explanation:
We have rations:
a:b=b:c, we can write that also like
a/b=b/c. Now we know that:
axc=bxb i.e
c=bxb/a, i.e. c/b=b/a then statmen 2 is TRUE.
Statmen 1 is not tru, because if a=c than we have a:b=b:a an it is true only if b=a, but we don’t have that information.
Statmen 3: suppose that
a:b=b:c=k, where k is some number. From that we get:
a=kb and c=b/k.
So b-a=b-kb=(1-k)b
And c-b=b/k-b=(1/k-1)b, these two statmen are equal only if k=1, i,e a=b=c but we dont have that information, so 3 is not true.
4. I think it is missing something??
5. If a=b than a:b=b:b=1, so it is b:c=1, i.e b=c, statement 5 is TRUE
Answer: 1,800
Step-by-step explanation: Divide 21,600 and 12 and you should get 1,800.
The number sentence that is true is B. 2.9 x 104 < 2.25 x 1011
2.9 x 104 = 301.6
2.25 x 1011 = 2,274.75
Therefore, 301.6 is less than (<) 2,274.75
