igor_vitrenko [27]

Answer:

6 years

Step-by-step explanation:

1.75% of 1,200 = 21

so 1 year= 21

21+21= 42         2 years

42+21=63           3 years

63+21=84            4 years

81+21=105             5 years

105+21=126            6 years

Or you can do

21x6=126 so it has to equal 6 years

Kevin Hill deposited 15,483 pennies. He put 50 pennies in each penny roll. How many full rolls did he have?​
Flauer [41]

Find how many full rolls he had by dividing 15,483 by 50:

15,483/50

= 309.66

What is B^y=x in logarithmic form?
Gala2k [10]

Answer:

The logarithmic function for x = 2y is written as y = log2 x or f(x) = log2 x. The number 2 is still called the base. In general, y = logb x is read, “y equals log to the base b of x,” or more simply, “y equals log base b of x.” As with exponential functions, b > 0 and b ≠ 1

How do I find Q15 c, d and e???
klasskru [66]
I would make a tree because there are not that many possibilities. to get 99 with numbers between 1 and 50 you have 50+49 and 49 and 50 nothing else will work because if one spin is less than 49 say 48 to get 99 you need 51 which is impossible. either you 50 then 49 or you get 49 then 50. the others are a bit harder because you need to find all possible spins that will sum to 52 which is a much larger number.
