Region B
The solution of two intersecting lines is the point that both share in common. From a point of view, it is the point where the two lines meet. In this case, the point is in quadrant 1, or Region B.
100 percent because 45 % is always in between 30 and 50 %
There are a total of 900 students at Molly’s school. 810 is 90% of 900. 90% of students did not wear a silly hat.
27.98ft
You can get this by using the tangent formula. The answer exactly expressed is 60tan25.
For this case we have an equation of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: decrease factor
t: time
Substituting values:
y = 30 * (b) ^ t
To calculate t we use a point in the table.
We have:
(t, y) = (1, 28.5)
Substituting:
28.5 = 30 * (b) ^ 1
b = 28.5 / 30
b = 0.95
Answer:
a. Decay factor is 0.95
