Answer:
The remainder is what decimal of yardage she can purchase. For example, if Tom wants to buy fabric that costs 10 dollars per yard, and he has 101 dollars, he can purchase 10.1 yards.
Your problem would come out to 3.3 yards because the remaining 2 dollars is worth 1/3 yards.
Step-by-step explanation:
Step-by-step explanation:
You've got the concept correct, but be careful with your parentheses. You should write it 3/(2n). Otherwise it looks like three halves n.
Consider this option (this is not the only way):
1. according to the condition 2345N is divisible by <em>6</em>, it means, that N is even number (0;2;4;6 or 8).
2. <em>6</em>=3*2, then the number 2345N is divisible by 3 also. It means, that the number (2+3+4+5+N)=(14+N) is divisible by 3, where N={0|2|4|6|8}.
3. using items 1 and 2:
(14+4)=18; only 18 is divided by 3, it means that N=4.
answer: 4.
Note also, that only 23451; 23454 and 23457 are divided by 3. Only 2345<u>4</u> is divided by 6 (2345<u>4</u>/6=3909).

Answer:
40.5 ft
Step-by-step explanation:
Solve for the time at which the balls meet, then find the corresponding height.
__
The balls will meet at the height such that the two values of h are the same.
-16t^2 +56t = h = -16t^2 +156t -248
0 = 100t -248
t = 2.48
Using the first equation to find h, we have ...
h = t(-16t +56) = 2.48(-16·2.48 +56) = 40.4736
The balls meet at a height of about 40.5 feet.
