Answer:

-2 $\sqrt{10$ +5

Step-by-step explanation:

The square root of 25 is 5. Perfect squares get taken out of the square root signs. 40 isn't a perfect square root so it breaks down into 2 and square root10. It is being subtracted so by a bigger number so it is going to be negative. Sorry if my explaining ins't the best. Good luck! I know math is SUPER hard. :)

The order of magnitude for total attended for a high school football team that averages 1,000 fans for each of its 5 home games

Tatiana [17]

The order of magnitude for total attended for a high school football team is 3

<h3>How to determine the order of magnitude?</h3>

The given parameters are:

Average number of fan = 1000

Number of home games = 5

The total number of fans in the 5 games is:

Total number of fans = Average number of fan * Number of home games

Substitute known values in the above equation

Total number of fans = 1000 * 5

Express 1000 as 10^3

Total number of fans = 10^3 * 5

Rewrite the equation as:

Total number of fans = 5 * 10^3

The power of 10 represents the order of magnitude

Since the power of 10 is 3, the order of magnitude is 3

Hence, the order of magnitude for total attended for a high school football team that averages 1,000 fans for each of its 5 home games is 3

Mrs.Henderson had 7/12dozen eggs in her refrigerator.Then she used 1/6 dozen eggs to make a cake.What fraction of a dozen is lef

zhuklara [117]

Ok so to find the eggs left we need to subtract but with fractions, you need a common denominator. You can multiply 1/6 by 2 because 6·2=12 which will be the same denominator as 7/12. You must multiply the numerator by 2 as well so 1/6· 2/2= 2/12. Now subtract 7/12 - 2/12 and you have 5/12 eggs left. :)

First you multiply the two numbers and get
1/6x3/5= 3/30

Then you reduce 3/30 and you get 1/10

So the final answer is 1/10!
