Answer:

w = 33.94 ft

Step-by-step explanation:the roof takes the shape of a right angle. The top of the roof is a right angle. To find the width of the house, which is the hypotenuse of the triangular roof, we would apply pythagorean theorem.

Thus:

w^2 = 24^2 + 24^2

w^2 = 1,152

Square both sides

\sqrt{w^2} = \sqrt{1,152}

w = 33.94 (to 2 decimal places)

The width of the house = 33.94 ft

The Flip-Flop-Alot Company makes and sells flip-flops. They have one linear function that represents the cost of producing flip-
Brums [2.3K]
If we let the number of flip-flops be x in the equation and that the cost would be y ( in terms of x) and the income would be z ( in terms of x), these equations will likely intersect each other during breakeven. That is, when the total revenue that the company will gain from sales of the flip-flops just be equal with the total cost.

Freezing point of salt water :

Freezing point of water - 7°C

0°C - 7°C

= - 7°C
