Darrin put the numbers 7.25, 7.52, and 5.72 and 5.27 in order from greatest to least.Is his work correct?Explain

Answers

Answer 1
Answer: if the order of the numbers in the question are the order Darrin put theem in then no, his work is not correct. this is because 7.25 is not greater than 7.52. the real order should be 7.52,7.25, 5.72, 5.27
Answer 2
Answer: His work was incorrect, the number has the  most value is the greatest number
Because 7 > 5, then 7.25 and 7.52 will be 1st and 2nd numbers and 5.72 and 5.27 will be 3rd and 4th numbers. 
Let's compare 7.25 and 7.52
Because 2 < 5 (the tenth digit) so 7.52 is 1st number and 7.25 is the 2nd number
Now, compare 5.72 and 5.27, again, 7 > 2 (the tenth digit) so 5.72 is 3rd number and 5.27 the 4th number.
Totally, the order from greatest to least is 7.52 , 7.25 , 5.72 , 5.27

it costs $15 per month for membership at a baseball club. Members pay $5 for game tickets. Write an expression for the cost of 1 month, including the membership fee, for a person who attends g games in month.

Answers

15+5G= total per month

explanation- your (15) is your constant variable. It will never change. The (5) will change depending on how many games you go to.

15+5G= Total
Y=15+5gY is the total cost in one month. 15 is the cost of the membership and 5 is the amount you paid to see the game. G is the variable for the amount of games. You multiple the g by 5 to get the total cost of games per a month that you went and saw. Than you add the base cost of 15 or your starting point. And you get your total cost.

How many digits are written when 1000 to the power of 2015 is expressed as a numeral?

Answers

Answer: There are 6046 digits will be written on expansion upto 2015th power.

Step-by-step explanation:

Since we have given that

1000^(2015)

We have to find the number of digits ,

So,

1000^(2015)\n\n=(10^3)^(2015)\n\n=10^(6045)

Since we know that

10^n\text{ has n+1 number of digits }

so,

10^(6045)\text{ has 6046 number of digits }

Hence, there are 6046 digits will be written on expansion upto 2015th power.

Final answer:

To find the number of digits in 1000 to the power of 2015, you would multiply the exponent by the logarithm of the base (10) and add 1.

Explanation:

To determine the number of digits in a large number expressed in scientific notation, you need to consider the exponent. In the case of 1000 to the power of 2015, the exponent is 2015. To find the number of digits, you would multiply the exponent by the logarithm of the base (10) and add 1. Therefore, the number of digits in 1000 to the power of 2015 is (2015 * log10(1000)) + 1.

Explain and demonstrate how to change 4/20 into a percent

Answers

4/20 is equivalent to 20%.

What is a expression? What is a mathematical equation?

  • A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
  • A mathematical equation is used to equate two expressions.
  • A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correctanalysis, observations and results of the given problem.

We have the following fraction -

4/20

We can convert it into percent as -

[x]% = (4/20) x 100

[x]% = 20%

Therefore, 4/20 is equivalent to 20%.

You can start by dividing both top and bottom by four, making it 1/5. From there you can do 1 divided by 5 making it a decimal of 0.2. Afterwards, move the decimal to places to the right and add an extra 0 making the percentage 20%.
