Answer:
5
Step-by-step explanation:
Whenever there are problems that have ladders leaning on a buildings, you have to know that is makes a right triangle.
3^2 + (x-1)^2 = x^2
(x-1)(x-1) = x^2 - 2x + 1
9 + x^2 -2x +1 = x^2
-x^2 -x^2
---------------------------------
-2x +10 = 0
-10 -10
---------------------
-2x=-10
-2x/2 -10/2
x=5 (the length of the ladder)

12/25
Step-by-step explanation:
Answer:
range = 18 and SD = 6
Step-by-step explanation:
range = max - min
= 228 - 210
= 18
FOR STANDARD DEVIATION * USE A SCIENTIFIC CALCULATOR THEY WON'T PENALIZE YOU*
follow these steps:
1. press mode then STAT
2. then press 1-VAR
3. put all the numbers on the table in ascending order
4 after press AC
5. press shift then 1
6. you will see many things but we are only interested in standard deviation, press *Var*
7. then select the standard deviation sign and press the equal sign
Answer: A

Answer:
Step-by-step explanation:
7259.75 - 7100 = 159.75
he earned 159.75 in interest
