Answer:
K = 9
Step-by-step explanation:
K/3 -2 =1
+2 +2.
K/3 = 3
*3 *3
K = 9
If we simply it, then it would be
3 + 2x + 6 + x = 15, which equals
3x + 6 + 3 = 15,
3x + 9 = 15,
if we subtract 9 from 15, we get 6. If we divide 3x by 3, and 6 by 3, we get 2.
Therefore x = 2, and we know there is a 10/15 chance to get a humbug, or a 1/3 chance.
Hope this helped.
Answer: OPTION B
Step-by-step explanation:
Let be "x" the acceptable lengths for the rod.
You know that the ideal length of the metal rod is 30.5 centimeters and the measured length may vary from the ideal length by at most 0.015 centimeters.
Therefore, knowing this, you can say that the acceptable lengths must be:
Therefore, the range of acceptable lengths for the rod is the following:

This range matches with the one shown in the option B.
Answer:
22 and 23
Step-by-step explanation:
let two consecutive number be
x and x+1
now,according to the question
x+x+1=45
or,2x=45-1
or,2x=44
or,x=44/2
:-x=22
Hence, the two consecutive numbers are
22 and 23
