Katie invests $5,000 in an account earning 4% interest, compounded annually for 5 years. Two years after Katie's initial investm

Lyrx [107]

Emily earned $166 more in her account than Katie.

We use the compound interest formula for both of these:

$A=p(1+r)^t$

For Katie's deposit:
$A=5000(1+0.04)^5=5000(1.04)^5 = 6083.26$

This gives Katie 6083.26-5000 = 1083.26 in interest (1083, to the nearest dollar).

For Emily's deposit:
$A=10000(1+0.04)^3=10000(1.04)^3=11248.64$

This means she earned 11248.64-10000=1248.64 in interest (1249, to the nearest dollar).

The difference in interest is given by 1249-1083=166

Answers:

slower train = 139 km per hour
faster train = 159 km per hour

=================================================

Explanation:

x = rate of the slower train

x+20 = rate of the faster train

rates are in km per hour, abbreviated as kph

The train traveling at x kph will travel 5x km after 5 hours.

Use this formula

distance = rate*time

Using that same formula, the faster train travels 5(x+20) = 5x+100 kilometers in 5 hours.

The two distances must add to 1490 if we want the trains to pass by each other. Assume that the trains are traveling on parallel side-by-side tracks.

--------------------------

So,

(slower train distance) + (faster train distance) = 1490

(5x) + (5x+100) = 1490

10x+100 = 1490

10x = 1490-100

10x = 1390

x = 1390/10

x = 139

The slower train moves at a rate of 139 km per hour.

x+20 = 139+20 = 159

The faster train moves at a speed of 159 km per hour.

--------------------------

Check:

The slower train travels 139 kph and travels for 5 hours, so it covers a distance of 139*5 = 695 km

The faster train has a speed of 159 kph and travels for 5 hours, so it covers 159*5 = 795 km

Total distance = 695+795 = 1490

The answers are confirmed.

What is the solution to the equation y3+4=120

ladessa [460]

To solve this problem first subtract the 4 from 120.
120 - 4 = 3y + 4(-4) =
116 = 3y.
Then divide both sides by three.
116 / 3 = 3y / 3 =
38.6666666667 = y
y = <span>38.6666666667.</span>
To double check the answer , 38.6666666667 x 3 + 4 = 120.
