13 vehicles (at least) will be needed to transport the students. 18x3= 54+10= 64\5= 12.8. Round 12.8 to the nearest while number is 13
The answer is -4. I solved it on a calculator and got -4
This is where the question tricks you, you have to make it even for us to find out the integer. So that 199 would turn into a 200.
And the integer between 1 and "200" would simply be 99.
Answer:
No
Step-by-step explanation:
The only arithmetic sequence of side lengths that will form a right triangle is (3, 4, 5) or some multiple of that, such as (9, 12, 15).
Sides of length 10, 11, 12 cannot form a right triangle.
Answer:
W=2001.24 newton meters
Caution: check units and arithmetic - I often make errors.
Step-by-step explanation:
Work is force times distance.
Denote height by h where h=0 is at ground level.
Denote the mass of the bucket and rope at height h by m(h).
The rate at which the bucket loses mass with height is (20-16)/10=0.4 kg/m
The rate at which the rope between the bucket and the top of the building loses mass is 0.4 kg/m
The initial mass of the bucket and rope is
The mass at height h is
The force required at height h is
m(h)g
where g is the gravitational acceleration.
g=9.81 meters/sec/sec
The work required is
Where a=0 and b=10
g(244-40)=204g
W=2001.24 newton meters
