Lelu [443]

It can be noted that the percentage error made by Allison will be 1.6%

<h3>How to solve the percentage</h3>

From the information given, Allison measured a line to be 19.4 inches long and the actual length of the line is 19.1.

Therefore, the percentage error will be:

= (19.4 - 19.1)/19.1 × 100

= 0.3/19.1 × 100

= 1.6%

In conclusion, the correct option is 1.6%.

Mnenie [13.5K]
There aren't any functions listed to choose from, but it should look something like the following:

E= total earnings that day
h= # hours worked that day
n= # people served that day

E= 7h + 5n

substitute 6 hours in for h

E= 7(6) + 5n

E= 42 + 5n OR E= 5n + 42

Hope this helps! :)

There are 120 people on the bus 50% get off at the first stop 20% get off at the second stop. The rest get off on the third stop
erastova [34]

Answer:

48 people

Step-by-step explanation:

First, find how many were left after the first stop:

120(0.5)

= 60

Find how many were left after the second stop:

60(0.8)

= 48

So, since the rest got off on the third stop, this means 48 people got off on the third stop.

Please help!!! Brainliest for whoever is right! What is the sum of the rational expressions below?
fenix001 [56]

Answer:

<h2>\frac{5 {x}^{2} + 5x + 3 }{3 {x}^{2}  + 3x}</h2>

Step-by-step explanation:

\frac{2x + 3}{3x}  +  \frac{x}{ x + 1}

Write all the numerators above the least common denominator

\frac{(x + 1)(2x + 3) + 3 {x}^{2} }{3x(x + 1)}

Multiply the parentheses

\frac{2 {x}^{2} + 3x + 2x + 3 + 3 {x}^{2}  }{3x(x + 1)}

Distribute 3x through the parentheses

\frac{2 {x}^{2}  + 3x + 2x + 3 + 3 {x}^{2} }{3 {x}^{2}  + 3x}

Collect like terms=\frac{5 {x}^{2} + 5x + 3 }{3 {x}^{2} + 3 x}

Hope this helps...

Good luck on your assignment...
