An art museum had 275,760 visitors last year. The museum was open every day of the year except for 5 holidays. Hoe many visitors did the museum have each day, on average

Answers

If we're assuming a 365-day year, then you simply subtract the five holidays from 365, giving us 360, then divide the number of visitors by that answer.

(275,260)/(360)≈765 visitors per day on average

Peter receives a $30000 salary for working as an engineer. If Peter spends 20% of his salary on expenses each year, then how much money does Peter have to spend on expenses?Identify the part, percent, and whole. Then solve with the formula

Answers

If Peter spends 20% of his salary on expenses, and his salary is $30,000, then all we need to do is find 20% of 30,000.

We can do this by converting 20% to a fraction or decimal. We'll do fraction because I think it is easier to see.

20% = 20/100 = 2/10 = 1/5

So we need to find 1/5th of 30,000

1/5 x 30,000 = 30,000/5 = 6,000

Therefore, Peter has $6,000 to spend on expenses.
Peter has $6000 to spend on expenses. You have to multiply 30000 time .20(the decimal form of 20%).

A rectangular parking lot has a perimeter of 232 feet. The length of the parking lot is 36 feet less than the width. Find the length and the width.

Answers

Answer:

The rectangular parking lot has a width of 76 feet and a length of 40 feet

Step-by-step explanation:

Let's find the length and the width of the rectangular parking lot, this way:

Perimeter = 232 feet

Perimeter = 2 Length + 2 Width

Length = Width - 36 feet

Now, substituting, we have:

2 (Width - 36) + 2 Width = 232

2 Width - 72 + 2 Width = 232

4 Width = 232 + 72

4 Width = 304

Width = 304/4 = 76 feet

Length = 76 - 36 = 40 feet

The rectangular parking lot has a width of 76 feet and a length of 40 feet

Decrease 42 by 15%.
it's for maths and it's decreasing percenages

Answers

OK so 1st you need to do 42 times .15 = 6.3 then you need to subtract that number from 42 which is 35.7 so that is your answer! I hope it helps :)
