Nick and June win some money and share it in the ratio 4:5. Nick gets £40. How much did June get?
sineoko [7]

Answer:

June gets \£50

Step-by-step explanation:

Let

x ----> amount of money Nick gets

y ----> amount of money June gets

we know that

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

x=40 ----> equation B

solve the system by substitution

substitute equation B in equation A

\frac{40}{y}=\frac{4}{5}

solve for y

Multiply in cross

(40)(5)=y(4)\\y=200/4

y=\£50

a barangay has 1000 individuals and its population doubles every 60 years. Give an exponential model for the barangay's populati
sdas [7]

Answer:

P(t) = 1000e^(0.01155)t

Step-by-step explanation:

Let the population of barangay be expressed according to the exponential formula;

P(t) = P0e^kt

P(t) is the population of the country after t years

P0 is the initial population

t is the time

If barangay has 1000 initially, this means that P0 = 1000

If the population doubles after 60years then;

at t = 60, P(t) = 2P0

Substitute into the formula

2P0 = P0e^k(60)

2 = e^60k

Apply ln to both sides

ln2 = lne^60k

ln2 = 60k

k = ln2/60

k = 0.01155

Substitute k = 0.01155 and P0 into the expression

P(t) = 1000e^(0.01155)t

Hence an exponential model for barangay's population is

P(t) = 1000e^(0.01155)t
