If Gary has seven suits, he can choose which of the seven he will place first. He can choose from the remaining six which one he will place next. This goes on until all the suits are placed in his wardrobe. In short, he can arrange his suits in 7! (7 factorial) ways in his wardrobe.
7! = 5040
Thus, Gary can arrange his suits in 5040 ways.
He had 28.5kg but then he sold 16.93kg so that would be 28.5kg - 16.93kg which is 12.57kg, and then he sold another 9.807 so you do 12.57 - 9.807 which is 2.763kg. Are you sure this is middle school maths and not primary school?
Answer: If Tara puts 4 pennies in for every one Sam does then after he puts in 10 she would of put 40.
She put in 40 pennies. Hope this helps ;)
A
Slope intercept form is y=mx+b. Plug in the m to make the equation y=6x+b. Then plug in the b to make the equation y=6x+4.2.
I didn't get the same answers.
In this problem, 25 is your constant (the number of baby hats you already started out with).
26 will be affected by your variable, d, the number of days. With each day that passes, 26 more hats will be knit, so the expression 26d can be used.
Set h equal to the constant + hats made per day to create an expression that you can use to solve for h:
h = 26d + 25
Now, just plug the numbers in for d to get h:
When d = 2, h = 26d + 25 = 26(2) + 25 = 77
When d = 4, h = 26d + 25 = 26(4) + 25 = 129
When d = 7, h = 26d + 25 = 26(7) + 25 = 207
When d = 9, h = 26d + 25 = 26(9) + 25 = 259
Your answers should be:
77
129
207
259
