Other number: x
one number: 5x - 2
x (5x - 2)=72
5x^2 - 2x = 72
Who names their child peppermint patty, I mean the candy is good but you gotta be pretty devoted to it to do that.
-------------------------------------------------------------
Define x :
-------------------------------------------------------------
Let the numbers be x, x+2 and x+4
-------------------------------------------------------------
Construct equation :
-------------------------------------------------------------
The sum of these number is 69
x + x + 2 + x + 4 = 69
-------------------------------------------------------------
Solve x:
-------------------------------------------------------------
x + x + 2 + x + 4 = 69
3x + 6 = 69
3x = 63
x = 21
-------------------------------------------------------------
Find the numbers :
-------------------------------------------------------------
x = 21
x+ 2 = 23
x + 4 = 25
---------------------------------------------------------------------------
Answer: The third number in the sequence is 25.
----------------------------------------------------------------------------
Ans: 8,736 cm 3
Volume of a rectangular prism = whl
When the dimensions are doubled
w= 13 * 2= 26 cm
l= 8 *2 = 16 cm
h= 10.5 * 2= 21 cm
V= 26*21*16
= 8,736 cm 3
To select 3 resistors of 10 resistors, the possible ways would be:
10C3= 10!/ (10-3)! 3!= 10*9*8 / 3*2= 120 ways
There are 2 defective resistors and 8 normal resistors. T<span>he possible ways to take 1 defective resistors and 2 normal resistors would be: 2C1* 8C2= 2* 8*7/2 = 56 possible ways
Then, </span>the probability of getting 1 defective resistor would be: 56ways / 120 ways= 46.7%
