Answer:

Hannah got $200 for her mom

Step-by-step explanation:

With the numbers in this question you don't even have to worry about percentages.

You can think of it in quarters:

75% is 3 quarters of 100%

(25% + 25% + 25% + 25%)

$150 is 3 quarters of $200

($50 + $50 + $50 + $50)

Hope this helps and isn't a confusing way of explaining it! :)

Find a rational number and an irrational number that are between 9.5 and 9.7.
IRISSAK [1]
So to better understand this question, let us define rational and irrational numbers first. Rational numbers are those numbers that can be written in fractions. On the other hand, irrational numbers are those numbers that cannot be written as fractions and the common example of it is pi. So, the rational number that is between 9.5 and 9.7 would be 9.6. This can be written as 9 and 3/5 or 48/5. And the irrational number would be <span>9.562359123571283578. Hope this answer helps.</span>

Ket [755]

The percent error is 4.167 %

<em><u>Solution:</u></em>

Given that, Mrs Franklin's speedometer said she was driving at a rate of 48 miles per hour

When checking the accuracy of her speedometer, an Automotive Specialist recorded her speed at 50 miles per hour

<em><u>The percent error is given by formula:</u></em>

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

\text{Percent error } = \frac{\text{experimental-theoretical}}{theoretical} \times 100

From given,

Experimental value = 50

Theoretical value = 48

<em><u>Substituting the values in formula, we get,</u></em>

Percent\ Error = \frac{50-48}{48} \times 100\\\\Percent\ Error = \frac{2}{48} \times 100\\\\Percent\ Error = 4.167

Thus the percent error is 4.167 %
