The mass of a particular substance is known to grow exponentially at a rate of 1.5% per day. Its initial mass was 230 grams and,
Papessa [141]

Answer:

23 days

Step-by-step explanation:

Given that the mass of a particular substance is known to grow exponentially at a rate of 1.5% per day

Initial mass = 230 gm

After t days, mass = 325 gm

The equation is

P(t) = 325 = 230 (1+\frac{1.5}{100} )^t\\\frac{325}{230} =1.015^t\\log 1.413 = t log 1.015\\t = \frac{log 1.413}{log 1.015} =\frac{0.1502}{0.0065} \\=23.229

Approximately after 23 days the mass will become 325 gms.

Mac has 117 white and black
olga55 [171]

Answer:

The number of white horses is 52

Step-by-step explanation:

Let

x ----> the number of black horses

y ----> the number of white horses

we know that

x+y=117 ----> equation A

\frac{x}{y}=\frac{5}{4}

x=\frac{5}{4}y ----> equation B

Substitute equation B in equation A and solve for y

\frac{5}{4}y+y=117

\frac{9}{4}y=117

y=117(4)/9\\y=52

therefore

The number of white horses is 52
