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.

a taxi fare y can be determined by the equation y=0.50x+3.50, where x is the number of miles traveled
Final answer:
The taxi fare is calculated with a linear equation that uses the number of miles traveled. The cost per mile is the slope (0.50) and the initial fare is the y-intercept (3.50). By substituting the number of miles into the equation, one can compute the total taxi fare.
Explanation:
The student's question involves understanding the equation of a linear function which describes a taxi fare. Specifically, the taxi fare y can be determined by the equation y=0.50x+3.50, where x is the number of miles traveled. The number 0.50 represents the slope of the line, which is the cost per mile, and the number 3.50 is the y-intercept, which is the initial fare before any miles are traveled.
Applying this knowledge to a practical example, if a person travels 5 miles, their taxi fare would be calculated by substituting x with 5 in the equation: y = 0.50(5) + 3.50, which equals 5.50 as the total fare.

At Raging River Sports, polyester-fill sleeping bags sell for $79. Down-fill sleeping bags sell for $149. in one week the store sold 14 sleeping bags for $1456. How many of each type of bag were sold
The store sold 9 polyester-fill sleeping bags and 5 down-fill sleeping bags.
We need to find the number of polyester-fill and down-fill sleeping bags sold.
Let's denote the number of polyester-fill sleeping bags as x and the number of down-fill sleeping bags as y. The given equations based on the problem statement are:
x + y = 14 (the total number of sleeping bags sold)
79x + 149y = 1456 (the total sales from sleeping bags)
We can solve this system of equations using either the substitution method or the elimination method. By multiplying the first equation by 79, we have:
79x + 79y = 1106
Subtracting this new equation from the second equation gives us:
149y - 79y = 1456 - 1106
70y = 350
y = 5
Substituting y = 5 into the first equation:
x + 5 = 14
x = 9

The perimeter of square is 1848 m.
What is Perimeter of Square?All sides add up to the perimeter.
Square perimeter equals the sum of its four sides' lengths.
= side +side +side +side.
= 4 x sides.
Square's perimeter is therefore equal to 4s units.
Given:
Side of Square = 462 m
Now, Perimeter of Square = 4 x side
Perimeter of Square = 4 x 462
Perimeter of Square = 1848 m

what is 304 divided by 2 minus 26 plus 17 times 16
Final answer:
The order of operations is followed to solve the expression 304 divided by 2 minus 26 plus 17 times 16, resulting in a final answer of 398.
Explanation:
The student is asking to solve the mathematical expression 304 divided by 2 minus 26 plus 17 times 16.
To solve this, we need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).
We first divide 304 by 2, then subtract 26, and finally add the result of multiplying 17 by 16.
Divide 304 by 2 to get 152.Subtract 26 from 152 to get 126.Multiply 17 by 16 to get 272.Add 126 and 272 to get the final result of 398.Calculation:
(304 / 2) - 26 + (17 * 16)
= (152 -26) + 272
= 126 + 272
= 398

I have 13.75 gallons of paint. I want to use 2/5 of paint to paint the living room. How many gallons of paint will I use.
The student will use 5.5 gallons of paint to paint the living room by multiplying 13.75 gallons by 2/5.
The student has 13.75 gallons of paint and wishes to use 2/5 of it to paint the living room. To calculate the amount of paint used, we multiply the total amount of paint by the fraction representing the portion they wish to use.
The calculation is as follows:
Amount of paint used = Total paint × Fraction of paint used
Amount of paint used = 13.75 gallons × 2/5
Amount of paint used = 5.5 gallons
Therefore, the student will use 5.5 gallons of paint to paint the living room.

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 =

------
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

= $200.

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.
