Answer:
Jack can take only 1 horse on his trailer to be towed by the truck without going over the maximum weight the truck.
Step-by-step explanation:
Given:
Weight of 1 horse = 1,200 lb
Weight of trailer = 2,700 lb
Jacks'truck can tow a maximum of 5000 pounds.
To find the maximum number of horses Jack can take in his trailer without going over the maximum weight his truck can tow.
Solution:
Let the maximum number of horses that Jack can take be =
Using unitary method to find weight of horses.
If 1 horse weights = 1,200 lb
Then horses will weight in lbs =
Total weight of horses and trailer in lbs =
Since the maximum weight the truck can tow = 5,000 lb, so the inequality can be given as:
Subtracting both sides by 2700.
Dividing both sides by 1200.
From the inequality solution for , we can conclude that Jack can take only 1 horse on his trailer to be towed by the truck without going over the maximum weight the truck.
Answer:
The surface are of a box = 1186.92 mm²
Step-by-step explanation:
Given in question as :
Diameter of cylinder = 18 mm
The height of cylinder = 12 mm
The surface area of cylinder = ( 2××r×h) + (2×
×r²)
where R is the radius , R = =
Or Radius r = 9 mm
Or, The surface area of cylinder= ( 2××9×12) + 2×
×(9)²)
Or , The surface area of cylinder=(678.24) + (508.68)
Or ,The surface area of cylinder= 1186.92 mm²
Hence the surface are of a box = 1186.92 mm² Answer
