Answer:
9
Step-by-step explanation:
It is a right angle triangle. Hypotenuse is 10, because it was 15 ft tall. 10 squared is 100. 5 squared is 25. 100 - 25 = 75. Sqrt 75 = 9
Answer:
16
Step-by-step explanation:
x^2-8x+k is a quadratic expression of the form ax^2 + bx + c. Here a = 1, b = -8 and c = k. Focus on x^2-8x and complete the square as follows: Take half of the coefficient of x (that is, take half of -8) and square the result:
(-4)^2 = 16; if we now write x^2-8x+ 16, we'll have the square of (x - 4): (x -4)^2.
Thus, k = 16 turns x^2-8x+k into a perfect square.
Answer:
The algebraic expression that represents the total amount of money (in dollars) in a cash register containing p pennies is:
Total amount = p/100 dollars
Note that to convert pennies to dollars, we divide the number of pennies by 100.

Answer:
Option D. Divide 15 by 2
Step-by-step explanation:
we know that
To find the y-coordinate of the midpoint of a vertical line, adds the y-coordinates of the endpoints and divide by two
we have the endpoints
(0,0) and (0,15)
The y-coordinate of the midpoint is (0+15)/2=15/2=7.5
therefore
Divide 15 by 2
Answer:
the answer is to count by hands ( A ) and divide 15 by 2 ( D )
