Answer:
First rectangle: 12 cm by 2 cm
Second rectangle: 8 cm by 3 cm
Step-by-step explanation:
You can examine factor pairs of 24 to see which pairs meet the requirements:
24 = 1×24 = 2×12 = 3×8 = 4×6
Factor pairs (2, 12) and (3, 8) have one factor that differs by 1 and another factor that differs by 4. We can use these numbers to describe the rectangles:
First rectangle: 12 cm by 2 cm
Second rectangle: 8 cm by 3 cm
Answer:
12cm.
Step-by-step explanation:
The radius is half of a circe.
6 * 2 = 12.
Answer: 14.4444444444 liters
Step-by-step explanation:
Since Carrie jared 13 liters of jam in 9 days, all you have to do is divide the number of liters, 13, by the number of days, 9, which equals 1.44444444444. Then, multiply 1.44444444444 by 10 days to get how many liters of jam Carrie could jar in 10 days, which is 14.4444444444 liters of jam.
The amount of the radioactive substance is 374.6 g
<h3>How to determine the amount of
radioactive substance?</h3>
The given parameters are:
- Initial, a = 424 mg
- Rate, r = 6%
- Time, t = 2 hours
The amount of the radioactive substance is calculated as:
A(t) = a(1 - r)^t
This gives
A(t) = 424 * (1 - 6%)^t
At 2 hours, we have:
A(2) = 424 * (1 - 6%)^2
Evaluate
A(2) = 374.6
Hence, the amount of the radioactive substance is 374.6 g
