Prime Factors of 504: 2, 3, 7
23 × 32 × 71 where 2, 3, 7 are prime.
Answer:
D
Step-by-step explanation:
1. Make it into a y = x equation
y = 9x +7
2. change x to y and y to x
x = 9y + 7
3. Isolate y ( if not possible, use implicit differentiation but here you can)
x-7 = 9y
1/9x-7/9 = y
the answer for A. 1/4. 2/4=1/2 3/4
Answer:
15 minutes
Step-by-step explanation:
Their rate together is 1/6 floor per minute.
Her rate alone is 1/10 floor per minute.
His rate is the difference of these:
1/6 - 1/10 = 5/30 -3/30 = 2/30 = 1/15 . . . . floor per minute
It would take Jacob 15 minutes to do it alone.
Answer:
! means factorial . For example 3! (factorial 3) = 3*2*1 = 6
Answer to 14C3 is 364
Step-by-step explanation:
14! = 14*13*12*11*10*9*8*7*6*5*4*3*2*1
14C3 = 14*13*12*11*10*9*8*7*6*5*4*3*2*1 / 3*2*1 * 11*10*9*8*7*6*5*4*3*2*1
= (14*13*12) / 3*2*1
= 14*13*2
= 364
