a parking lot has 20 empty space. if the ratio of empty spaces to taken spaces is 5:2, how many spaces are there total?
The total number of spaces in the parking lot is 28, calculated by using the ratio of empty spaces to taken spaces (5:2) and knowing there are 20 empty spaces.
To calculate the total number of parking spaces in the lot, given a ratio of empty spaces to taken spaces, we use the information provided: there are 20 empty spaces and the ratio of empty spaces to taken spaces is 5:2. To solve this, set up a proportion with the given ratio:
5 (empty spaces) : 2 (taken spaces) = 20 (empty spaces) : x (taken spaces)
Now, cross-multiply and solve for x:
5x = 2 × 20
5x = 40
x = 40 / 5
x = 8
There are 8 taken spaces. Now, add the empty spaces to get the total:
Total spaces = empty spaces + taken spaces
Total spaces = 20 + 8
Total spaces = 28
So, the total number of spaces in the parking lot is 28.

The price of an item has increased 15% since last year. However, a person can buy the item for a 25% employee discount. The employee pays $172.50. What was the price last year?
Answer:
The employee pays $172.50 and he got 25% employee discount.
If the cost is $100, he pays $(100 - 25) = $75.
So, employee pays =
100
------
75
.
172.50
= $230.00.
Again, price was increased by 15% last year. So whose cost is $100
is sold by $(100+15) = $115.
When sell price is $115, then cost price is $100. Then,
when sell price is $230, then cost price is
100
------
115
⋅
230
= $200.

I am a 3-digit odd number greater than 800. My tens digit is 2 less than my ones digit. I am divisible by 3 but not 5. The sum of my digits is 12. Whats the number? DUDE HURRY ALWAYS HAVE HOPE
Final answer:
The number that fits all the conditions given is 835. It's a 3-digit odd number greater than 800, with a sum of digits equaling 12, tens digit 2 less than the ones digit, divisible by 3 but not 5.
Explanation:
To solve the problem, we need to find a 3-digit odd number greater than 800, divisible by 3 but not 5, with the sum of the digits equaling 12 and the tens digit being 2 less than the ones digit. Starting with the sum of the digits being 12, we can form possible combinations of three digits that add up to 12. Considering that the number is odd and greater than 800, our hundreds digit must be 8. To be divisible by 3, the sum of the digits must also be divisible by 3, which we already know is valid. Now, since the number is not divisible by 5, the ones digit cannot be 0 or 5. Therefore, we establish our ones digit first, which could be 1, 3, 7 or 9. Since the tens digit is 2 less than the ones digit, we cannot have 1 as our ones digit because that would make the tens digit negative.
With these constraints in mind and trying possible combinations, we realize that a workable combination is 8 for the hundreds place, 3 for the tens place (2 less than 5), and 5 for the ones place, giving us the number 835. This number satisfies all conditions: it's a 3-digit number, odd, greater than 800, divisible by 3, not divisible by 5, and the sum of its digits is 12.

300 girls were asked to name their favorite sport.12 girls said they like bowling. What is the percentage of girls who like bowling?
To calculate the percentage of girls who like bowling, you would divide the number of girls who like bowling (12) by the total number of girls (300) and then multiply by 100. This yields a result of 4%.
Explanation:To find the percentage of girls who mentioned bowling as their favorite sport, you would use the following formula:
Number of favorites / Total number * 100
In this instance, the calculation would be:
12 girls / 300 girls * 100
By doing this calculation, you get 4% which indicates that 4% of girls mentioned bowling as their favorite sport.

James's garden has a length of 12 1/4 feet and a width of 9 2/3 feet. What length of fencing will he need to surround his garden? Please show how you got the answer.
James will need 43 5/6 feet of fencing to surround his garden.
What is the length of fencing needed to surround the garden?Given the parameter:
Length of the garden = 12 1/4 feet
Width of the garden = 9 2/3 feet
Perimeter =?
To determine the length of fencing James will need to surround his garden, we can use the formula for the perimeter of a rectangle:
Perimeter = 2( length + width )
Plug in the values and solve for the perimeter:
Perimeter = 2( 12 1/4 + 9 2/3)
Perimeter = 2( 49/4 + 29/3)
Perimeter = 2( 263/12 )
Perimeter = 263/6
Perimeter = 43 5/6 feet
Therefore, the needed length of fencing is 43 5/6 feet.

instead of using the distributive property to expand 0.25 x (16.60a + 12.20y) could you have first found the sum 16.60a +12.20y explain
Answer:
Distributive property is the same as product of sum
So
0.25 (16.6 a + 12.2 y) = 0.25 × 16.6a + 0.25 × 12.2y = 0.25 [16.6 a + 12.2 y]

A store sells 3 ears of corn for $1 they round prices to the nearest cent.Tell whether you would describe the relationship between cost and number of ears of corn as proportional relationship justify your answer
The relationship between the number of ears of corn and cost is proportional because for every set of 3 ears of corn bought, the cost is a consistent $1, which maintains a constant ratio.
Explanation:A store sells 3 ears of corn for $1, and they round prices to the nearest cent. We need to determine if this represents a proportional relationship between the cost and the number of ears of corn. A proportional relationship means that the ratio between two quantities is constant. Here, for every 3 ears of corn, the cost is $1. If we buy 6 ears of corn, the cost would be $2, and so on. This pattern indicates that the relationship is proportional because the ratio of corn to dollars is always 1:3 or $0.33 per ear of corn, rounded to the nearest cent.
