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
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.
Step-by-step explanation:
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.
Answer:
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 , where x is the number of years.
Since,
i.e. .
Therefore, the monthly growth rate function becomes,
i.e. .
i.e. .
Hence, the monthly growth rate is i.e. .
Also, the growth factor is given by = 0.075.
Thus, the growth factor to nearest thousandth place is 0.075.
(c) -4
(d) 4
