Answer:
9.7 miles
Step-by-step explanation:
The shortest distance between 2 points is a straight line
The distance from point A to point B is
d = sqrt( ( x2-x1)^2 + ( y2-y1) ^2)
d = sqrt( ( 3 - -3)^2 + ( 4-1) ^2)
d = sqrt( ( 6)^2 + ( 3) ^2)
d = sqrt(36+9)
d = sqrt(45)
d =6.7 to the nearest tenth
The distance from point B to point C is
d = sqrt( ( x2-x1)^2 + ( y2-y1) ^2)
d = sqrt( ( 3 - 3)^2 + ( -2-4) ^2)
d = sqrt( ( 0)^2 + ( -6) ^2)
d = sqrt(36)
d = 6
But They only made it half way so 1/2 (6) =3
Add the distances together
6.7+3 = 9.7 is the minimum distance
Answer:
8
Step-by-step explanation:
Key to this question is assume that each exchange preserves the total dollar amount of Nick’s money.
If He exchanges all his $5 bills for $1 bills, it means that a $5 bill will result in 5 $1 bills as such, if he had x number of $5 bill, after the exchange, he would have 5x $1 bills.
then all his $20 bills for $5 bills, it means that for each $20 bill, he gets 4 $5 bills which means that if he had y number of $5 bills, after the exchange, he would have 4y $5 bills.
and finally all his $100 bills for $20 bills, then he must have received 5 $20 bills for each $100 such that if he had z number of $100 bills before the exchange, he would have 5z number of $20 bills after the exchange. Given that originally he had 17 bills and later 77 bills then
x + y + z = 17
5x + 4y + 5z = 77
Multiplying the first equation by 5,
5x + 5y + 5z = 85
5x + 4y + 5z = 77
subtract 2 from 1
y = 8
