Answer: 20%

Step-by-step explanation:

Given : The expected weight of new born lion = 2.8 pounds

The actual weight of new born lion = 3.5 pounds

The formula to find the percent error is given by :-

\text{Percent error}=\dfrac{|\text{Expected value-Actual value}|}{\text{Actual value}}\times100\\\\\Rightarrow\ \text{Percent error}=\dfrac{|2.8-3.5|}{3.5}\times100\\\\\Rightarrow\ \text{Percent error}=\dfrac{0.7}{3.5}\times100\\\\\Rightarrow\ \text{Percent error}=20\%

Therefore, the zookeeper’s percent error = 20 %

How can you make your answer (41-13i)/(25) into a+bi form?
KengaRu [80]

Hello, do you know that for any a, b and c real numbers with c different from 0 the following is correct?

\dfrac{a+b}{c}=\dfrac{a}{c}+\dfrac{b}{c}

Then,

\dfrac{41-13i}{25}=\dfrac{41}{25}-\dfrac{13}{25}i

So,

a=\dfrac{41}{25}\\\\b=\dfrac{-13}{25}

Thank you.

Which of the following options is a better purchase for a bicycle? Option 1: A cash sale for $88
stellarik [79]

<u><em>Answer:</em></u>

Option 3

<u><em>Explanation:</em></u>

<u>To get the value of the cheapest bike, best option, we will calculate the total cost of each bike:</u>

<u>i- Option 1:</u>

Total cost = $88

<u>ii- Option 2:</u>

$5 down payment and $8 per week for 10 weeks

Total cost = 5 + 8(10) = 5 + 80 = $85

<u>iii- Option 3:</u>

$12 down payment and $5 per month for 12 months

Total cost = 12 + 5(12) = 12 + 60 = $72

<u>iv- Option 4:</u>

$20 down payment and $20 per month for 12 months

Total cost = 20 + 20(12) = 20 + 240 = $260

<u>Now, from the above calculations, we can conclude that:</u>

The best price would be that of option 3 ($72). It is the lowest price compared to other option.

Hope this helps :)

9. A box of cereal is packaged and sold at a local
emmasim [6.3K]

Answer:

288 Cubic Inches

Step-by-step explanation:

Assuming the cereal takes up 80% of the total volume of the box, you would take 80% of the total volume.

First, do Base x Width x Height for the volume of the box.

10 inches x 3 inches x 1 foot      (1 foot is 12 inches)

10 x 3 x 12 = 360

Now, take 80% of 360 cubic inches.

80% is 0.8 times a number

0.8 x 360 = 288

288 Cubic Inches
