Nita wants to buy a new keyboard for her computer. she will buy the keyboard when it is on sale for under $50. write an inequality that describes k the price in dollars at which nita will buy the keyboard.

The inequality will be:  

Step-by-step explanation:

Nita will buy the keyboard when it is on sale for under $50.

That means, the price of the keyboard should be any positive value between 0 and 50.

If the price of the keyboard is   dollars, then the value of will be greater than 0  and also less than 50.

Thus the inequality will be:  

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
