Step-by-step explanation:
the correct formula for this is the heron's formula
which states that s=√s(s-a)(s-b)(s-c). Where s is a+b+c all divided by 2
s=√(13.5-12)(13.5-9)(13.5-6)
s=√(1.5)(4.5)(7.5)
s=√50.625
s= 7.11 or 7 to the nearest square unit
0.000565 - this is a simple standard form question (if the 10 is to the power of a negative number, the answer will always be extremely low!)
1st one is 512L
2nd one is 125mL
let me know if im wrong
Answer:
d. 1
Step-by-step explanation:
The base for this "exponential" function is sufficiently close to 1 that the function looks linear. The value corresponding to x=0 seems to be 1.00. Rounded to tenths, it is 1.0.
Elio is right in assuming the relationship between the height and the hours it burns is proportional.
Find the unit rate
14 ÷ 8 = 1.75 cm/h
Divide
21 ÷ 1.75 = 12
You can set this up as an algebraic equation to check the answer.
If the candle is 21 cm tall, it will burn for 12 hours.
Hope this helped you! :)
