39 inches is the longest bc a foot is 12 inches and the longest feet the is 3 feet or a yard. So 12 x 3 = 36 and that is 3 inches short than 39 so 39 is the longest.
Answer:
∠2 = 152
Step-by-step explanation:
A straight angle should always equal 180, and that is really the key to how we answer this problem. That means that ∠1 and ∠2 are supplementary, and add up to 180°.
That means that 180-28, will give us our other angle.

Answer:
The product is approximately 5400.
Step-by-step explanation:
9 1/16 rounded to the nearest whole number is 9.
645 3/5 rounded to the nearest hundred is 600.
Multiplying these values gives a product of 9·600 = 5400.
The product is approximately 5400.
Answer:
Step-by-step explanation:
1) For each situation to grow or decay by a constant percent rate, it must be exponential. Therefore, the correct examples are
A. The number of cars sold doubles every year. It is a 200% growth every year.
D. Each time you start a car engine the remaining engine life decreases by 0.0075%. A case of decay
E. The number of people creating cat videos increases by 15% percent every year.
F. Computer technology increases by a factor of 3 every five years.
2) this is a case of exponential decay. The expression for exponential decay is
y = b(1 - r)^t
y = final value
b = initial value
r = decay rate
t = time
Given that
r = 10% = 10/100 = 0.1
b = 50 kilograms
y = W kilograms
The relationship is
W = 50(1 - 0.1)^t
W = 50(0.9)^t
