The number of grams of a radioactive isotope present after t years is 1,500(1/2)^t. What does 1,500 represent if
t>0
A. The original number of grams of the radioactive isotope present
B. The number of grams of the radioactive isotope present after 1/2 year
C. The number of grams of the radioactive isotope present after 2 years
D. The final number of grams of the radioactive isotope present

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

radha is now 5 years old

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
