Step-by-step explanation:
P(t) = 12,000 (2)^(-t/15)
9,000 = 12,000 (2)^(-t/15)
0.75 = 2^(-t/15)
ln(0.75) = ln(2^(-t/15))
ln(0.75) = (-t/15) ln(2)
-15 ln(0.75) / ln(2) = t
t = 6.23
Answer:
1.5b (kg)
Step-by-step explanation:
Let's begin by listing out the variables we were given:
weight of the watermelon = b (kg),
weight of watermelon = (2/5) * weight of candies
weight of candies = 1 ÷ (2/5) = 1 ÷ 0.4
weight of candies = 2.5b (kg)
How much is the weight of the box of candies greater than the weight of the watermelon is given by:
weight of the box of candies - weight of watermelon= 2.5b - b = <u>1.5b</u> (kg)
<u>Therefore, the weight of the box of candies is greater than the weight of the watermelon by 1.5b (kg) </u>
Answer:
4 ways.
Step-by-step explanation:
The total amount of candy she has is 15 + 9 = 24 pieces. She has three younger brothers, and 24 is divisible by 3 (24/3 = 8). 15 and 9 are also both divisible by 3 (15/3 = 5 and 9/3 = 3).
-She can give them each 5 tootsie rolls.
-She can give them each 3 twizzlers.
- She can give them each 5 tootsie rolls and 3 twizzlers (if she were to give them all of the candy)
- She can give them one of each which would leave her 12 tootsie rolls and 6 twizzlers (which is the best option if she's trying to save for herself)
I see 4 ways to do this, and 2 ways after her mother asks her to give at least 1 type of candy to each of them.
