Answer:
36 cm^2.
Step-by-step explanation:
The area is half the product of the lengths of its diagonals.
(PA)(LY) = (12cm)(6cm)
= 72 cm
72cm ÷2= 36 cm^2
Therefore the area is 36 cm^2
Answer:
It would take 12 men 4.5 (four and a half) days to do the same amount of work as the 9 men in 6 days.
Step-by-step explanation:
9 is 75% of 12 (12*.75=9) if they work at the same rate it would take 75% of the time it did for the 9 men (6hrs*.75=4.5)
Answer:
28.125
Step-by-step explanation:
If it is going 45mph and every hour it decreases 1.6mph per inch of snow added. so 45 divided by 1.6 is 28.125.
To find the relationship between them, lets do some algebra:
f(x) = (7/10)^x
g(x) = (7/10)^-x
if we do:
f(x) * g(x) = 1
due to exponents multiplying addition law, therefore, the relationship, gives:
f(x) = 1 / g(x)
