A car traveled from city a to city b at an average speed of 3x miles per hour, where x > 0. the car then immediately returned

dlinn [17]

This is a classic question on Speed, time, & distance.

1. When time traveled in each segment is constant, then average speed is simple mean of speeds.

2. When distance traveled in each segment is constant, then average speed is reciprocal of simple mean of reciprocal of speeds. It is basically called Harmonic mean.

So this question falls in the category of 2.

=> So, average speed = Reciprocal of mean of reciprocals of 40 & 50.

=> Average speed = Reciprocal of mean of 1/40 & 1/50.

<span>=> Average speed = Reciprocal of (1/40 + 1/50)/2 = Reciprocal of (5+4)/400 = 44 4/9 .
Hope this helps</span>

Alexis put $2000 in a savings account. After 4 years, she had $2543 in the account. What rate of interest did she earn? Use the

natta225 [31]

Alrighty

P=2000
A=2543
t=4

$A=Pe^{rt}$
$2543=2000e^{4r}$
solve

$2543=2000e^{4r}$

divide both sides by 2000

$\frac{2543}{2000}=e^{4r}$

take ln of both sides

$ln(\frac{2543}{2000})=ln(e^{4r})$

$ln(\frac{2543}{2000})=(4r)ln(e)$

$ln(\frac{2543}{2000})=(4r)(1)$

$ln(\frac{2543}{2000})=4r$

divide both sides by 4

$\frac{ln(\frac{2543}{2000})}{4}=r$

use your calculator

0.060049=r
convert to percent
that is about 6%

the interest rate is 6%

Answer:

Step-by-step explanation:

she wrote it to solve the total amount spent on both T shirt.

30+6x=20+8x-8x

30+6x-8x=20

30-30-2x=20

-2x=20-30
