Answer:
all real numbers less than or equal to –3
Step-by-step explanation:
Look at the y-values that the graph shows. There are none greater than -3. Any value of -3 or less is possible.
Answer:
Ending Amount = Beginning Amount / 2 ^ n
where 'n' = number of half-lives n = 65 / 29 = 2.2413793103
Ending Amount = 25 g / 2^2.2413793103
Ending Amount = 25 / 4.7284892286
Ending Amount = 5.2871009727 g = 5.29 g (rounded)
Step-by-step explanation:
Answer:
Number of sundaes = 36
Number of banana split = 28
Step-by-step explanation:
On that day, let the number of sundaes sold be x
Now, since they sold 8 more sundaes than banana, the number of bananas sold is x-8
So the cost of sundaes sold will be 2 * x = 2x
the total cost of banana splits sold will be 3(x-8) = 3x -24
The addition of both equals 156
Hence;
2x + 3x-24 = 156
5x -24 = 156
5x = 156 + 24
5x = 180
x = 180/5
x = 36
So
number of sundaes sold is 36 while the number of bananas split sold is 36-8 = 28
