Answer:
18 cm, 24 cm, 30 cm
Step-by-step explanation:
30² = 18² + 24²
900 = 324 + 576
900 = 900
Answer:
54
Step-by-step explanation:
2x+2=3x-52
subtract 2 from both sides
2x=3x-54
x=54
Answer:
A. 9.8 ft
Step-by-step explanation:
first convert the degrees to radians:
80° x (pi/180) ≈ 1.396
arc length = r x θ (always in radians)
= 7 x 1.396
= 9.772 ≈ 9.8 ft
Answer:

Step-by-step explanation:
Let t represent the number of years since 2005.
We have been given that the number of people afflicted with the common cold C in the winter months steadily decreased by 202 each year from 2005 until 2010.
The number of people decreased in t years would be
.
We are also told that in 2005, 12,073 people were afflicted. So 12,073 will be initial value.
We will represent our given information in an equation as
, where,
m = Slope of line,
b = The initial value.
Since the number of people afflicted with the common cold C in the winter months steadily decreased, so slope will be negative.
Substitute the given values:

Therefore, our required equation would be
.
