$25;300%increse percent change

Answers


well and 300% increase means you multiply by 3 and then add the original number


in this case 300% of 25 is 75 and its an increase so 25+75=100

the answer is 100

Jane is 7 years older than John.If the sum of their ages is 43.How old is Jane and how old is John​

Answers

Answer:

If

Jane= x

John = y

y+7= x

x-y=7 ---- (1)

x+y=43 --- (2)

(1) + (2),

x-y+x+y=7+43

2x=50

x= 50÷2

x= 25

substituting x= 25 in (2),

25+y=43

y= 43-25

y= 18

Jane is 25 years old and John is 18 years old.

Derek found a function that approximately models the population of iguanas in a reptile garden, where x represents the number of years since the iguanas were introduced into the garden.i(x) = 12(1.9)^x


Rewrite this function in a form that reveals the monthly growth rate of the population of iguanas in the garden. Round the growth factor to the nearest thousandth.

Answers

Answer:

i(x)=12 * (1+(0.9)/(12))^(12x) and growth rate factor is 0.075

Step-by-step explanation:

The function that models the population of iguanas in a reptile garden is given by i(x)=12 * (1.9)^(x), where x is the number of years.

Since, i(x)=12 * (1.9)^(x)

i.e. i(x)=12 * (1+0.9)^(x).

Therefore, the monthly growth rate function becomes,

i.e. i(x)=12 * (1+(0.9)/(12))^(x * 12).

i.e. i(x)=12 * (1+(0.9)/(12))^(12x).

Hence, the monthly growth rate is i.e. i(x)=12 * (1+(0.9)/(12))^(12x).

Also, the growth factor is given by (0.9)/(12) = 0.075.

Thus, the growth factor to nearest thousandth place is 0.075.
