side c = 150 feet of flowers

Area = 5400 feet squared

concert question:

The converse of the Pythagorean theorem can help you determine whether the roped off area is in the shape of a right triangle because you use the side lengths of each square and enter them into the equation, and if the equation is true, then it is a right triangle

Concession stand question:

The school banner can fit across the length of the concession stand

the following information is missing

The length if the sides: c is 50 feet long, b is 40 foot long, and a is 30-foot long.

The distance between the two red stars of the picture makes the hypotenuse of a right triangle, where two sides of length a (30 ft) are the legs. From Pythagorean theorem, diagonal of square A is:

diagonal² = 30² + 30²

diagonal = √1800  = 42.43 ft

which is longer than the banner.

Blueprint question:

No, diagonal of square C is 70.71ft

michael rented a truck for one day. there was a base fee of $20.95 , and there was an additional charge of 93 cents for each mil
jonny [76]
Let x = number of miles, cost per mile = 93 cents = $0.93 

Cost = 20.95 + 0.93*x 

200.44 = 20.95 + 0.93x

0.93x + 20.95 = 200.44

0.93x = 200.44 - 20.95

0.93x = 179.49

x = 179.49/0.93

x = 193

He drove 193 miles.
