Answer:

Step-by-step explanation:

Pythagorean Theorem

a²+b²=c²

(c² is the hypotenuse)

a² + 40² = 41²

a² + 1,600 = 1,681

subtract 1681-1600 in order to isolate a², which is the missing leg we are trying to find

a² = 81 in order to find our answer, we isolate a by squaring both sides

√a² = √81

a = 9

Our answer is 9.

A certain television is advertised as a 53-inch TV (the diagonal length). If the width of

zhenek [66]

The TV is 45 inches tall.

Step-by-step explanation:

The diagonal length of television = 53 inches

Width of TV = 28 inches

As TV is in rectangular or square shape, a diagonal will form a right triangle

Where,

Diagonal = hypotenuse = c = 53 inches

Width = base = b = 28 inches

Length = perpendicular = a

we will use pythagorean theorem to find the length.

$a^2+b^2=c^2\\a^2+(28)^2=(53)^2\\a^2+784=2809\\a^2=2809-784\\a^2=2025$

Taking square root on both sides

$\sqrt{a^2}=\sqrt{2025}\\a=45$

The TV is 45 inches tall.

Tickets for a raffle cost $13. There were 810 tickets sold. One ticket will be randomly selected as the winner, and that person

Assoli18 [71]

Answer:

$ -11.61

Step-by-step explanation:

The expected value in this case would be the subtraction between the probability that the draw will win for its value (the prize + value of the ticket) and the value of the ticket for the probability of not winning the draw, thus:

(1/810) * (1100 + 13) - (809/810) * (13)

1,374 -12,984 = -11.61

which means that the expected value is $ -11.61
