Answer:

4.2%

Step-by-step explanation:

percent error = (estimated value - actual value)/(actual value) × 100%

Here, the estimated value is 250 g, and the actual value is 250 g.

percent error = (estimated value - actual value)/(actual value) × 100%

percent error = (250 g - 240 g)/(240 g) × 100%

percent error = 10/240 × 100%

percent error = 0.041666... × 100%

percent error = 4.2%

Step-by-step explanation:

the real thing is 240 grams.

the estimation of 250 grams was 10 grams off.

how many % is that ?

for that we need to divide these 10 by 1%.

and 1% is 240/100 = 2.4 grams.

10 / 2.4 = 4.166666666... ≈ 4.2%

the percent error is 4.2%

PLEASE HEP ME QUICK!!!!: Tom travels between the two mile markers shown and then finds his average speed in miles per hour. Sele
slega [8]

Answer:

speed=\frac{195\ miles}{3\ hours}

3\ hours=\frac{195\ miles}{speed}

3\ hours*(speed)=195\ miles

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x -----> the distance in miles

y ----> the time in hours

speed=\frac{x}{y}

we have

The distance is equal to subtract 35 miles from 230 miles

x=230-35=195\ miles

The time is equal to subtract 1:30 pm from 4:30 pm

y=4:30\ pm-1:30\ pm=3\ hours

substitute in the formula of speed

speed=\frac{195\ miles}{3\ hours}

<em>Isolate 3 hours</em>

3\ hours=\frac{195\ miles}{speed}

<em>Isolate 195 miles</em>

195\ miles=3\ hours*(speed)
