Answer:
1287
Step-by-step explanation:
Number of people in elevator , n = 8
Number of floors, r = 6
Since they all look alike, arrangement doesn't matter, the we use combination :
(n+r-1 r - 1) = (8+6-1 C 6-1) = 13C5
Recall:
nCr = n! / (n-r)!r!
13C5 = 13! / (13-5)!5!
13C5 = 13*12*11*10*9 / 5*4*3*2*1
= 1287
This is a division problem. You can use the standard algorithm of 128/ 5. Or you can create equal groups (draw five circles) and count out eggs until you distribute them all. I would start with 20 in each circle. That would be 20+ 20+ 20+ 20+ 20= 100 Then think 128-100= 28 Next count by 5's. 5+ 5+ 5+ 5+ 5= 25 Then think what is 28-25= 3 so 128/ 5= 25 with a reminder of 3 eggs left over.
Answer:
The volume(V) of gas will increase when the pressure of the gas decreases assuming all the other variables are held constant.
Step-by-step explanation:
P = Pressure of the ideal gas
V = Volume of the ideal gas
n = Moles of the ideal gas
R = Universal gas constant
T = Temperature of the ideal gas
Answer:
B(4,-2) D(-3,5)
Step-by-step explanation:
you must graph the points and project the lines in X and Y until they intersect and form a square
I attached an image
Required number is 17.
<h3>Justification:</h3>
<u>We need to find the largest number that will divide 398, 436 and 542 leaving remainders 7, 11 and 15 respectively</u>.
Hence, we need to find the HCF of 3 numbers (398-7), (436-11) and (542-15).
Hence,
- 398 - 7 = 391
- 436 - 11 = 425
- 542 - 15 = 527
Now, you can find the HCF(391, 425, 527) = 17
<u>Hence, the largest number that will divide 398, 436 and 542 leaving remainders 7, 11 and 15 respectively is 17</u>.
