How might this number be shown on a calculator?<br> 5.31x1037 (37 is above 10)<br> [?]e[ ]

Arisa [49]

Answer:

$5.31E37$

Step-by-step explanation:

Given

$5.31 * 10^{37}$

Required

How it'd be displayed on a calculator

Standard calculators, today are built to always convert huge numbers or extremely small number to scientific notations;

This was done to allow the calculator fit each values on its screen

$5.31 * 10^{37}$ is such a big number that it'll require the calculator to display it using scientific notations;

So, basically we have to convert $5.31 * 10^{37}$ to scientific notaton;

This is achieved by replacing $*10^{37}$ with $E37$

So, $5.31 * 10^{37}$ is equivalent to $5.31E37$

Write each Percent as a decimal and as a mixed number or fraction in simplest form

sveticcg [70]

$p\%=\dfrac{p}{100}\\\\225\%=\dfrac{225}{100}=2\dfrac{25}{100}=2.25=2\dfrac{1}{4}\\\\550\%=\dfrac{550}{100}=\dfrac{55}{10}=5\dfrac{5}{10}=5.5=5\dfrac{1}{2}\\\\0.8\%=\dfrac{0.8}{100}=\dfrac{0.8\cdot10}{100\cdot10}=\dfrac{8}{1,000}=0.008=\dfrac{1}{125}\\\\0.06\%=\dfrac{0.06}{100}=\dfrac{0.06\cdot100}{100\cdot100}=\dfrac{6}{10,000}=0.0006=\dfrac{3}{5,000}$

<em>IMPORTANT THIGNS TO REMEMBER:</em>

Has 20 lb. dog food!
Gives dog 1 3/5 everyday!
Find how much eaten after 2 days!
Find how much is left!

<em>ANSWER:</em>

Dog has eaten 3 1/5 after 2 days!

There is 16 4/5 left in bag!

<em>EXPLANATION:</em>

Since she gives 1 3/5 to her dog everyday and their asking for 2 days you would multiply 1 3/5 × 2 OR add 1 3/5 + 1 3/5

Which would give you 3 1/5

So, the dog has eaten 3 1/5 lb. of dog food in 2 days.

However then, you would subtract 20 lb. - 3 1/5 lb. because there is 20 lb. dog food in all and the dog has eaten 3 1/5 of it. This would give you 16 4/5 lb.

Meaning there is 16 4/5 lb. left in the bag of dog food!
