The first and third are correct. They are equal.
The second is incorrect. This is because 1800 meters = 1.8 km (not 18 km). The answer you should have is a "less than sign" because 1.8 km is smaller than 18 km.
To go from meters to kilometers, you move the decimal point 3 spots to the left. This is the same as dividing by 1000.
To go from kilometers to meters, you move the decimal point 3 spots to the right. This is the same as multiplying by 1000.
Answer:
The answer to your question is a) 588.6 N b) 132.3 N
Step-by-step explanation:
Data
mass = 60 kg
weight = ?
Process
1.- Write the formula of weight
Weight = mass x gravity
gravity = 9.81 m/s²
2.- Substitution
Weight = 60 x 9.81
3.- Result
Weight = 588.6 kg m/s² = 588.6 N
4.- Convert Newtons to Pounds
1 pound ----------- 4.45 N
x ----------- 588.6 N
x = (588.6 x 1) / 4.45
x = 132.3 pounds
if there are 4 numbers that average to 60, when mutiplied they must come up to: 60*4= 240
100+30+45= 175
240-175= 65
PROOF:
100+30+45+65= 240
240÷ 4
= 60
Answer:
He can make a maximum of $480.
Step-by-step explanation: Technically he can win all 60 times so the maximum is 60*8 = 480
Answer:
V = 500 pi in^3
or approximately 1570 in ^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
The diameter is 10. so the radius is d/2 = 10/2 =5
V = pi (5)^2 * 20
V = pi *25*20
V = 500 pi in^3
We can approximate pi by 3.14
V = 3.14 * 500
V = 1570 in ^3
