I think the answer is 12/20 or 3/5 because out of the 20 marbles you are drawing 4 orange and 8 blue and replacing it. So 8+4=12 and there are 20
Step-by-step explanation:
Step one:
given data
we are told that she wants her balance to be at least $100
y=100-------1
the expression relating her current balance and spending rate is
let y be the total and m be the number of months
y=330-11m----------2
Required
the number of months m
equating 1 and 2 we have
100=330-11m
11m=330-100
11m=230
m=230/11
m=20.9
m=21 approx
This means that she will keep her account open for 1 year 9 months
360 degrees is the whole circumference.
300 degrees is 300/360 of the circumference.
The circumference: pi*r*2 = 4*pi = approximately 12.566.
300/360*12.566=10.472 = answer
Answer is option C.
m(x) = -7x
This is a bijective function.
Here for everyvalue of theres is only one and one unique value of y.
And hence its inverse will also be a function.
