What are some numbers that have an absolute value greater than 2 1/2
The numbers that have an absolute value greater than 5/2 are 4 and 5.
In general, ImI > 5/2. Where m is any number.
What is an absolute value?The absolute value of a number is the distance value from zero without considering the sign of a number. It is also represented as |x|, where x is any number.
Given:
The absolute value is [tex]2\frac{1}{2}[/tex].
[tex]2\frac{1}{2}[/tex] = 5/2
And we have to find the numbers that have the greater absolute value than 5/2.
5/2 = 2.5.
Any number that is greater than 2.5 is the required number.
Let 4 and 5 re the numbers.
Then, 4 > 5/2 and 5 > 5/2.
Therefore, 4 and 5 are the numbers.

Samuel has a coupon for 25% off the regular price of one item at the toy store. He buys a dirt bike that has a regular price of $419.99. The Kentucky tax rate is 6%, what is the price of the dirt bike after the coupon is used. Show your work!
The price of the dirt bike after the coupon is used and after applying the Kentucky sales tax is $333.89. The discount amount is $105, and the sales tax amount is $18.90.
Explanation:To find the price of the dirt bike after the coupon is used, we first need to calculate the amount of the discount. The regular price of the dirt bike is $419.99, and the coupon gives a 25% discount. To find the discount amount, we multiply the regular price by 0.25: $419.99 x 0.25 = $105. Next, subtract the discount from the regular price: $419.99 - $105 = $314.99.
Next, we need to calculate the sales tax. The regular price after the discount is $314.99. The Kentucky tax rate is 6%, which we convert to a decimal by dividing by 100: 6 ÷ 100 = 0.06. To find the amount of sales tax, multiply the regular price after the discount by the sales tax rate: $314.99 x 0.06 = $18.90.
Finally, to find the price of the dirt bike after the coupon and sales tax, add the regular price after the discount and the sales tax: $314.99 + $18.90 = $333.89. Therefore, the price of the dirt bike after the coupon is used and after applying the Kentucky sales tax is $333.89.

A local grocery store sells oranges $1.15 per pound, tax included. A shopper buys 1.3 pounds of oranges from the store. Rounded to the nearest cent, how much does the shopper pay for the oranges?
the price for one pound is $1.15
to find the total cost you need to multiply the cost of one pound by the total weight of how much was bought
they bought 1.3 pounds, so multiply 1.3 by 1.15 for the total cost
1.15 * 1.3 = 1.495 which rounds up to $1.50
the shopper paid $1.50
How many gallons of a plant food that is 9% nitrogen must be combined with another plant food that is 25% nitrogen to make 10 gal of a plant food that is 19% nitrogen?
To determine the amounts of two plant foods with different nitrogen percentages to create a desired mixture, we set up and solve a system of equations based on the total volume and total nitrogen content.
Explanation:A mixture problem that involves combining two solutions with different percentages of nitrogen to achieve a solution with a desired percentage of nitrogen.
Let's denote the amount of the 9% nitrogen plant food as x gallons and the amount of the 25% nitrogen plant food as y gallons.
Given that we want to end up with 10 gallons of a 19% nitrogen mixture, we can form the following two equations based on the problem's requirements:
Equation 1: x + y = 10 (Total volume of the mixture)
Equation 2: 0.09x + 0.25y = 0.19 × 10 (Total amount of nitrogen in the mixture)
By solving this system simultaneously, we can find the values of x and y.
The second equation can also be written as 9x + 25y = 190 to work with whole numbers.
We can multiply the first equation by negative 9 and add it to the second equation to eliminate x and solve for y.
This will give us the amount of 25% nitrogen plant food needed, and by subtraction of y from 10, we can find the amount of 9% nitrogen plant food required.
Based on the results, we may need multiple gallons of the 9% nitrogen plant food and a specific number of gallons of the 25% nitrogen to achieve our desired 19% nitrogen plant food.
Final answer:
To find the number of gallons of a 9% nitrogen plant food to be combined with a 25% nitrogen plant food, we can set up an equation based on the principle of conservation of mass and solve for the variable representing the number of gallons of the 9% nitrogen plant food.
Explanation:
To find out how many gallons of a plant food that is 9% nitrogen must be combined with another plant food that is 25% nitrogen to make 10 gallons of a plant food that is 19% nitrogen, we can set up an equation based on the principle of conservation of mass.
Let x be the number of gallons of the 9% nitrogen plant food.
Then, (10 - x) would be the number of gallons of the 25% nitrogen plant food.
The equation can be set up as follows:
0.09x + 0.25(10 - x) = 0.19(10)
Solving the equation will give us the value of x, which represents the number of gallons of the 9% nitrogen plant food needed to be combined with the 25% nitrogen plant food.

on an average day, 34 customers buy a bag of grapes at jerry's market. there are an average of 47 grapes in each bag. round to the nearest ten and then multiply to estimate the number of grapes jerry's customers buy every day.
Answer:
Step-by-step explanation:
1,500
There are on an average 34 customers for Jerry everyday buy a bag of 47 grapes. Hence, around 1600 grapes he sell every day.
To estimate the number of grapes Jerry's customers buy every day, we can multiply the average number of bags sold by the average number of grapes per bag:
34 bags/day x 47 grapes/bag = 1598 grapes/day
Rounding 1598 to the nearest ten gives us:
1600 grapes/day
Therefore, we can estimate that Jerry's customers buy around 1600 grapes every day.
