Y=7×2^t/30 what is the equation solved for t​
CaHeK987 [17]

Answer:

Option C

Step-by-step explanation:

Given expression in the question is,

y = 7(2)^{\frac{t}{30}}

To get the value of t,

\frac{y}{7}=2^{\frac{t}{30}}

Take the log on both the sides of the expression,

log(\frac{y}{7}) = \text{log}[(2^{\frac{t}{30}})]

log(\frac{y}{7}) = \frac{t}{30}(\text{log2})

t = 30(\frac{\text{log}\frac{y}{7}}{\text{log}2} )

t = 30[\text{log}_2(\frac{y}{7})] [Since, \frac{\text{loga}}{\text{logb}}=\text{log}_a(b)}]

Therefore, Option C will be the answer.

The cost of 3 candles is 19.50 what is the unit price with work shown
kobusy [5.1K]
Well, since 3 candles are 19.50, simply divide. This will make a ratio so that 1 candle will equal 6.50 per candle.

19.50 / 3 candles = 6.50 per candle.
