Answer:

\boxed{10.4 \%}

Step-by-step explanation:

\text{Percent error} = \frac{\lvert\text{Predicted - Actual}\lvert}{\text{Actual}} \times 100\%

Data:

Predicted = 275 lb

  Actual = 307 lb

Calculation

\text{Percent error} = \frac{\lvert275 - 307\lvert}{307} \times 100\%\\\\= \frac{\lvert-32\lvert}{307} \times 100\%\\\\= \frac{32}{307} \times 100\%\\

= 0.104 × 100 %

= 10.4 %

The percent error of the zookeeper's prediction was \boxed{10.4 \%}.

Answer:

a taco is 1.25 and a drink is 0.95

Step-by-step explanation:

tacos = t

drinks = d

5t + 3d = 9.10

3t + d = 4.70

this is a simultaneous equation so times the first one by one and the second by 3 and then take them away from each other and solving to get

t = 1.25 and d=0.95

one drink is $0.95

one taco is $1.25

Hope this helps!!

Help me decrease 25 by 30%
Marysya12 [62]

Step-by-step explanation:

Percentage decrease = 30% × 25

New value = 25 - Percentage decreaseNew value =

25 - Percentage decrease =

25 - (30% × 25) =

25 - 30% × 25 =

(1 - 30%) × 25 =

(100% - 30%) × 25 =

70% × 25 =

70 ÷ 100 × 25 =

70 × 25 ÷ 100 =

1,750 ÷ 100 =

17.5

Absolute change (actual difference) =

New value - 25 =

17.5 - 25 =

- 7.5

How do you do number 1?
Alla [95]

Answer:

The decimal is not a rational number.

REASON:

A decimal can be a rational number if it fulfills any of the two conditions.

  • Condition 1:

            It must be Terminating. This means that the decimal should have finite number of digits.

  • Condition 2:

        If it is non-terminating decimal it should be Recurring. This means the decimal should repeat itself after some specific digits.
