Each of the three oldest children sleeps in a twin bed. They all need bed sheets. A brand of sheets is on sale for “Buy one get one at 50% off”. If each sheet costs $18.00, how much will two sheets cost? How much will six sheets cost?
Using arithmetic operations, The total cost of six sheets will be:
$27.00 + ($9.00 x 4) = $63.00
If each sheet costs $18.00, then the cost of the first sheet will be $18.00, and the cost of the second sheet will be 50% of $18.00, or $9.00.
So, two sheets will cost the cost of the first sheet plus the cost of the second sheet, which is:
Using addition,
$18.00 + $9.00 = $27.00
For six sheets, we can use the same logic: the first two sheets will cost $27.00, and the next four sheets will be half off. So, the cost of the next four sheets will be 50% of $18.00, or $9.00 each.
Hence, the total cost of six sheets will be:
$27.00 + ($9.00 x 4) = $63.00

Then, the number of pounds of food that an adult manatee can eat in "d" days can be represented by the equation: p = r x d.
What is equation?An equation is a mathematical statement that shows that two expressions are equal. It consists of two parts: the left-hand side (LHS) and the right-hand side (RHS), separated by an equals sign (=). The equals sign indicates that the two expressions are equal, and the goal of solving the equation is to find the value of x that makes this statement true. Equations can be solved using various algebraic techniques, such as simplifying and rearranging the expressions, applying operations to both sides of the equation, and factoring or expanding expressions. Solving an equation involves finding the values of the variables that make the equation true.
Here,
Let's assume that an adult manatee eats "r" pounds of food per day on average. Then, the number of pounds of food that an adult manatee can eat in "d" days can be represented by the equation: p = r x d
Here, "p" represents the number of pounds of food, "r" represents the average amount of food consumed per day, and "d" represents the number of days. So, if we know the average amount of food consumed by an adult manatee per day, we can use this equation to calculate how much food it will eat in any given number of days.

Jorge's 3/4 hr drive to a job was part city and part country drivingIf 2/11 hr was city driving, how much time was spent on country driving?
Using arithmetic operation, the value for time spent on country driving is obtained as 25/44 hour.
What is arithmetic operation?
A subject of mathematics known as arithmetic operations deals with the study and use of numbers in all other branches of mathematics. Basic operations including addition, subtraction, multiplication, and division are included.
Jorge's drive was 3/4 hour, and 2/11 hour of that time was spent on city driving.
To find the time spent on country driving, we can use arithmetic operation of subtraction.
Subtract the time spent on city driving from the total driving time -
Time spent on country driving = Total driving time - Time spent on city driving
= 3/4 hour - 2/11 hour
To subtract these fractions, we need a common denominator.
The smallest number that 4 and 11 both divide into is 44 -
3/4 = 33/44
2/11 = 8/44
So -
Time spent on country driving = 33/44 hour - 8/44 hour
= (33 - 8)/44 hour
= 25/44 hour
Therefore, Jorge spent 25/44 hour driving on country roads.

Ms. Monroe ordered 24 costumes from Tip-Tap dance supply for each of her dance students to wear at an upcoming recital. Since she ordered during the store's end-of-season sale, Tip-Tap took $3.50 off the price of each costume. Ms. Monroe paid $516 in all.
Answer:
the original price of each costume was $25, and the sale price was $(25-3.50) = $21.50.
Step-by-step explanation:
Let the original price of each costume be $x. The sale price of each costume will be $(x-3.50). Ms. Monroe ordered 24 costumes, so the cost of 24 costumes at the sale price will be:
24 × (x-3.50) = $24x - $84
Ms. Monroe paid $516 in all, so we can write:
24x - 84 = 516
Adding 84 to both sides, we get:
24x = 600
Dividing both sides by 24, we get:
x = 25
Therefore, the original price of each costume was $25, and the sale price was $(25-3.50) = $21.50.
Answer: so Ms.Monroe got $84 off her entire purchase

Starting from home, you drive a certain distance south to Best Buy to get a new monitor for your computer. You then drive 5 miles west to return that awful shirt your mother bought you for your birthday. You then drive 25 miles home. How far is it from your home to Best Buy?
Answer:
To solve this problem, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.
In this case, we can consider the distance from home to Best Buy as the hypotenuse, and the distance traveled west and south as the other two sides.
Let's call the distance from home to Best Buy "x". Then, using the Pythagorean theorem:
x^2 = (distance south)^2 + (distance west)^2
We know that the distance west is 5 miles, and the distance home is 25 miles. We don't know the distance south, so let's call that "y".
Then we have:
x^2 = y^2 + 5^2
25^2 = y^2 + 5^2
Solving for y, we get:
y^2 = 25^2 - 5^2
y^2 = 600
y = sqrt(600)
y = 24.49 (rounded to two decimal places)
Now we can plug in y to find x:
x^2 = y^2 + 5^2
x^2 = 24.49^2 + 5^2
x^2 = 625.12
x = sqrt(625.12)
x = 25.00 (rounded to two decimal places)
Therefore, the distance from home to Best Buy is approximately 25 miles.

The amount of depreciation to be recorded for year 2 using the straight-line method of calculating depreciation is $6,750.
What is the amount of depreciation to be recorded for year 2?Straight-line depreciation is calculated by dividing a fixed asset's depreciable base by its useful life. The depreciable base is the difference between an asset's all-in costs and the estimated salvage value at the end of its useful life.
By using the straight-line method of calculating depreciation, the annual depreciation expense would be calculated as follows:
= (Purchase Price - Salvage Value) / Useful Life
= ($60,000 - $6,000) / 8 years
= $54,000 / 8 years
= $6,750.

Find all points having an x-coordinate of 2 whose distance from the point (-2,-4) is 5
The two points with an x-coordinate of 2 and a distance of 5 from (-2, -4) are: (2, -4 + 2√13) and (2, -4 - 2√13)
What is distance formula?
Distance is a measurement of how far away two things or locations are, either numerically or occasionally qualitatively.
Distance formula: [tex]distance = \sqrt{((x2 - x1)^2 + (y2 - y1)^2)}[/tex]
We can solve this problem using the distance formula, which gives us the distance between two points in a plane:
[tex]distance = \sqrt{((x2 - x1)^2 + (y2 - y1)^2)}[/tex]
Let (x, y) be a point with an x-coordinate of 2. Then we can write the distance from (-2, -4) to (x, y) as:
[tex]distance = \sqrt{((x - (-2))^2 + (y - (-4))^2)}[/tex]
Simplifying this expression, we get:
[tex]distance = \sqrt{((x + 2)^2 + (y + 4)^2)}[/tex]
We know that the distance between (-2, -4) and (x, y) is 5. Therefore, we can write:
[tex]\sqrt{((x + 2)^2 + (y + 4)^2)} = 5[/tex]
Squaring both sides, we get:
[tex](x + 2)^2 + (y + 4)^2 = 25[/tex]
Expanding the left side, we get:
[tex]x^2 + 4x + 4 + y^2 + 8y + 16 = 25[/tex]
Simplifying this expression, we get:
[tex]x^2 + 4x + y^2 + 8y - 5 = 0[/tex]
To find all points with an x-coordinate of 2 that satisfy this equation, we can substitute x = 2 and simplify the resulting equation:
[tex]2^2 + 4(2) + y^2 + 8y - 5 = 0[/tex]
Simplifying this equation, we get:
[tex]y^2 + 8y + 3 = 0[/tex]
We can solve this quadratic equation using the quadratic formula:
y = (-b ± sqrt(b^2 - 4ac)) / 2a
where a = 1, b = 8, and c = 3.
Plugging in these values, we get:
y = (-8 ± sqrt(8^2 - 4(1)(3))) / 2(1)
Simplifying this expression, we get:
y = (-8 ± √52) / 2
y = (-8 ± 2√13) / 2
y = -4 ± √13
Therefore, the two points with an x-coordinate of 2 and a distance of 5 from (-2, -4) are: (2, -4 + 2√13) and (2, -4 - 2√13)

The point A' is located in Quadrant IV, because it has a positive x-coordinate and a negative y-coordinate, which is the characteristic of points in this quadrant.

Chris throws a ball upward. The height of the ball, in meters, t seconds after being
thrown is modeled by h (t)= 8t-5t² +4. After how many seconds will the ball reach
the ground?
Answer:
When the ball hits the ground, its height will be 0 meters. Therefore, we need to solve the equation:
h(t) = 0
8t - 5t^2 + 4 = 0
We can solve this quadratic equation by factoring or by using the quadratic formula, but in this case, it's easier to use factoring:
(5t - 4)(t - 1) = 0
From this equation, we can see that either 5t - 4 = 0 or t - 1 = 0. Solving for t in each case, we get:
5t - 4 = 0 ==> t = 0.8 seconds
t - 1 = 0 ==> t = 1 second
Therefore, the ball will reach the ground after either 0.8 seconds or 1 second, depending on the initial height of the ball.
