Answer:
Here's how to do it.
Step-by-step explanation:
The two triangles must be similar, that is, corresponding angles must be equal, as in the diagram below.
1. Find a corresponding pair of sides
Assume that ∆ABC is the original and ∆DEF is its scaled image.
Then, AB and DE are corresponding sides, with lengths of 8 and 12 units , respectively.
2. Set up a ratio
Ratio = side length in image/side length in original = 12/8
3. Simplify the ratio
The simplified ratio is the scale factor (SF).
SF = 12/8 = 3/2 = 1.5
The scale factor is 1.5.
Answer:
Step-by-step explanation:
Given that the time to complete a standardized exam is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
P(completing exam before 1 hour)
= P(less than an hour) = P(X<60)
=P(Z<
)
=0.5-0.34=0.16
i.e. 16% of students completed the standardized exam.
Answer: a result or effect of an action or condition.

Answer:
(i) Approximately 3 half lifes
(ii) 
Step-by-step explanation:
(i) ∵ The half life of Radon-222 is approximately 3.8 days,
So, the number of half life in 11.46 days = 
≈ 3
(ii) Since, the half life formula is,
Where,
= initial quantity,
t = number of periods
= half life of the quantity,
Given,
N = 
t = 11.46 days,
