25. Tom and Jerry must stuff and mail 1000

poizon [28]

Answer:

Step-by-step explanation:

The general formula for this is

Formula

1/t1 + 1/t2 = 1/t_tot

givens

t1 = 6 hours

t2 = x

t_tot = 4 hours

Solution

1/6 + 1/x = 1/4 Subtract 1/6 from both sides.

1/6-1/6 + 1/x = 1/4 - 1/6 Change to 12 as your common denominator

1/x = 3/12 - 2/12 subtract

1/x = 1/12 Cross multiply

x = 12

Tom would need 12 hours to do the job alone.

Solve equation 1102 Base 3= 212 Base n

Norma-Jean [14]

Answer: 4

Step-by-step explanation:

$1102_{3}=2+0(3)+1(9)+1(27)=38\\\\212_{n}=2+1(n)+2(n^2)=2n^2 + n+2\\\\\implies 2n^2 + n+2=38\\\\2n^2 + n-36=0\\\\(n-4)(2n+9)=0\\\\n=-\frac{9}{2}, 4$

However, as the base must be positive, n=4.
