Answer:
The answer would be D = 4 or option 2.
Step-by-step explanation:
9/12 = 3/?
First, you want to simplify 9/12
9/12 = 3/4
This shows you that D = 4
Answer:
a = 10 and b = 6
Step-by-step explanation:
I am having a little trouble reading the numbers, but I think that I see

If we wrote this in expanded form, it would look like:
How many 7s are on the top? 10 That is the answer to a. The product of powers principle tells us that if we are multiplying powers with the same bases we add the exponents 2 + 8 = 10

Now it looks like
if we cross the 7's out in the top and the bottom, we are left with 6 7's on the top. That is the answer to b.
The quotient of powers principle tells us that if we are dividing powers with the same bases, we can subtract the exponents (10 -4 = 6)
What is 0.00340.78 correct to 3 significant figures?
a significant fugure is when the number lean solething ,so its can anyone except 0
so if we are reducing 0.00340.78 to 3 significant number
first we have to look for the significant nulber ,which are 3,4,7,8
so the answer can be 0.0034.7
hopefully this helps
