Step-by-step explanation:
1 hour = 60 minutes
40 minutes out of an hour can be written as: 40/60
Fraction = 40/60
= (2 × 30) / (3 × 20)
Canceling out common factors of numerator and denominator, we get 2/3
Therefore, 40 minutes is 2/3 of an hour.
Hello,
Let's factor:
2(4x-1)² * (x+5) + 6(4x-1)³ * (x+5)
=2(4x-1)²(x+5)*[1+3(4x-1)]
=2(4x-1)²(x+5)(12x-2)
=4(4x-1)²(x+5)(6x-1)
Answer:
D = 55 feet
Step-by-step explanation:
Let below sea level is negative direction and above sea level is positive direction.
A deep sea diver is at 45 feet below sea level = -45 feet
A helicopter is at 100 feet above sea level = +100 feet
We need to find the distance between the helicopter and deep sea diver. It can be calculated by simply adding the above data as follows:
D = -45 +100
= 55 feet
Hence, the distance between the helicopter and deep sea diver is 55 feet.
