First off change everything to minutes. The 600 is irrelevant in this problem. He can mow this size in 80 minutes. 8 hours is 8x60= 480. 480/80 is 6 and therefore he can mow 6 lawns in this size in time of 8 hours
Hello!
To understand this question we first need to find some common measurements to make this math easier.
One day is equal to 24 hours.
One hour is equal 60 minutes.
One day in hours would be equal to 24 · 60, or 1440 minutes.
1440 is equal to 100% of our day.
To find 50% we can then divide that value in half to get 720 minutes.
Half of that value, or 25%, is equal to 360 minutes.
Answer:
C = 110 cm
Step-by-step explanation:
The circumference is given by
C = pi *d
C = 3.14 * d
C = 3.14 * 35
C =109.9
Rounding
C = 110 cm
<span>(4 · 2^5) ÷ (2^3 · 1/16 )
</span>= (2^2 · 2^5) ÷ (2^3 · 2^-4 )
= (2^7) ÷ (2^-1)
= 2^8
