There are 100 bacteria in a jar. Every day, the number of bacteria increases 25%. In approximately how many days will there be 5

algol [13]

Use compound interest formula

$\\ \rm\Rrightarrow P(1+r/100)^t=500$

$\\ \rm\Rrightarrow 100(1+0.25)^t=500$

$\\ \rm\Rrightarrow (1.25)^t=5$

$\\ \rm\Rrightarrow log(1.25)^t=log5$

$\\ \rm\Rrightarrow tlog1.25=log5$

$\\ \rm\Rrightarrow t(0.097)=0.3$

$\\ \rm\Rrightarrow t=3.3\approx 3$

The selling price for a classic car is $12,000, which is $500 less than two times its original price. What was the original pric

Rashid [163]

Answer:$6250

Step-by-step explanation:

selling price(sp)=12000

Original price(op)=?

sp+500=2 x op

12000+500=2 x op

12500=2 x op

Divide both sides by 2

12500/2=(2 x op)/2

6250=op

Therefore original price is $6250

What is t ? 3t - 2/3=1+t

MatroZZZ [7]

<span>3t - 2/3=1+t
we need to separate t. subtract t from both sides.
2t - 2/3 = 1
add 2/3 to both sides.
2t = 1+2/3
2t = 3/3 + 2/3
2t = 5/3
divide 2 by both sides.
t = 5/6</span>
