Answer:
Step-by-step explanation:
Given
--- candles melted
--- time to melt
Required
The time since the first was lit
If 1 candle melts in 4 hours, 2 candles will melt in 8 hours.
i.e.
For the 3rd candle that has melted, 4 inches
First, calculate the fraction that melt
The time to melt is:
So, the required time is:
Convert to minutes
Answer: Change the number: 36
To:48
Step-by-step explanation:
12x2 is 24 but 24 x 2 isn’t 36
Log (5) + log (3) = log (15)
Answer:
12 units
Step-by-step explanation:
Because the two triangles are similar:

Answer:
x⁷ = 60
Step-by-step explanation:
<u>Given</u><u> </u><u>:</u><u>-</u><u> </u>
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u><u> </u>
- The expotential equation .
<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>
Given logarithmic equation is ,
⇒ log x⁵ + log x ¹² = 7
⇒ log x ⁵ * ¹² = 7 [ log aⁿ + log aⁿ' = log aⁿ * ⁿ' ]
⇒log x ⁶⁰ = 7
In expotential form we can write it as ,
⇒ x⁷ = 60
