Zina [86]

Answer:

2 dimes, 1 nickel and 3 quarters.

Step-by-step explanation:

The price of 2 postcards is $1. Any combination of coins that adds to $1 will work here. Remember, a penny is worth 0.01, a nickel is worth 0.05, a dime is worth 0.10, and a quarter is worth 0.25.

Adding 2 dimes, 1 nickel, and 3 quarters would be 2(0.10)+1(0.05)+3(0.25)=1.

Solve r/n + t = 4v for r

lana [24]

Since r is being divided by N, we need to multiply both sides by N.
We are left with R + T = 4v/n
Now, we subtract T from each side. The equation is now R = 4V/N - T
We have now solved for R.

A man commutes to work a distance of 4040 miles and returns on the same route at the end of the day. His average rate on the ret

Vladimir [108]

Answer:

$T(x) = \frac{80x+1000}{x^2+25x}$

$T(30) = \frac{3400}{1650} = 2.061$

Step-by-step explanation:

If the rate is x, then the rate of the return is x+25. In both trips, he has 40 miles to travel, therefore, it will take 40/x hours in the first trip and 40/x+25 for the return. As a consecuence

$T(x) = \frac{40}{x} + \frac{40}{x+25} = \frac{40 ( x+(x+25))}{x(x+25)} = \frac{80x+1000}{x^2+25x}$

Also,

$T(30) = \frac{80*30+1000}{30^2+25*30} = \frac{3400}{1650} = 2.061$

This means that if he starts at 30 miles per hour, it will take a bit more than 1 hour to be there: 1 hour and 20 minutes in the first trip, and a bit more than 40 minutes (40/55 hours) in the return.
