perimeter = sum of all sides
27 = 9+7.8+x
x (third side) = 10.2
Answer:
156.25 grams
Step-by-step explanation:
Well, for starters we know that the substance decays by 2% each day and its been decaying for 34 days. Therefore, the substance has decayed by 68%
34 x 2 = 68
Hence, 50 grams is 32% because the substance has already decayed by 68%
100 - 68 = 32
So now we know 50 grams is 32%. Now we need to find how much 100% is.
50 - 32%
X - 100%
We cross multiply.
50 x 100 = 5000
And divide.
5000 / 32 = 156.25
Thus, in the beginning, there were 156.25 grams in the substance.
Hope this helps! :)
Answer:
outlier
Step-by-step explanation:
it is way to far away to be any of those other options. that means it is an outlier.
Perimeter = 2* length + 2 * width
12 feet = 2* 3 feet + 2 * width
2 * width =12 feet -2* 3 feet
2 * width =6 feet
width = 3feet
Answer:
about 30.1 astronomical units or 4.5 billion kilometers.
