A tent is in the shape of an equilateral triangle. The triangularbase has a length of 4 feet and a height of 3.5 feet. The
rectangular sides and bottom of the tent have the dimensions
of 6 feet by 4 feet. The surface area of the tent is
square feet.

Answers

Answer 1

Answer:

The surface area of the tent is 86 ft²

Surface area of a triangular prism

SA = area of base + area of top + area of the three sides

Therefore,

The base and top are triangular.

Therefore,

area of base = 1 / 2 bh = 1 / 2 × 4 × 3.5 = 7 ft²

area of the tope = 7 ft²

Therefore, the other three rectangular sides are calculated as follows:

area = 6 × 4 = 24 ft²

Therefore,

Surface area = 7 + 7 + 24 + 24 + 24 = 86 ft²

Answers

(2/3 bed) / (6min) = ('x' bed) / (1min)

Cross-multiply:

(2/3 bed * 3min) = ('x' bed * 6min)

Divide each side by 6min:

1/3 bed = 'x' bed

it takes 1 gallon of diesel 1 fuel for a cruise ship to trarel 6 inches how many gallons will it take for the cruise ship to travel 1 mile

Answers

The last cruise I went on had a cocktail party for returning guests, which the captain attended to participate in a question and answer conversation. One of the questions asked pertained to the amount of fuel a cruise ship uses. I can't remember everything that was said, but I do remember the captain saying one gallon of fuel moved the ship a mere 17 inches!! So I would imagine close to a thousand gallons of fuel would be needed to move the ship one mile..
