The correct answer would be 21 feet, as the image shown is an equilateral triangle. Thus, finding the perimeter we add up all sides and get the answer of 21 feet, which is less than 28 feet as needed.
Answer:
The possible numbers the chemistry club could rent the room is less than 6 hours(t<6)
Step-by-step explanation:
Reservation fee = 15
Additional fee of 5 per hour
If the chemistry club wants to spend less than 45 on renting the room, let the possible number of hours be t.
t = time
15 + 5t < 45
5t < 45 - 15
5t < 30
t < 30/5
t < 6 hours
Work out 3/8 of 48.
First of all divide 48 by the denominator:
48 ÷ 8 = 6 (this gives 1/8 of 48)
Now multiply this answer by the numerator:
6 × 3 = 18 (this gives 3/8 of 48)
Answer:
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and gamma decay (γ-decay), all of which involve emitting one or more particles. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetic and strong forces.[1]
