During a sale, a store offered a 25% discount on a bed that originally sold for $800. After the sale, the discounted price of the bed was marked up by 25%. What was the price of the bed after the markup? Round to the nearest cent.
Answers
The price of the bed after mark up is $475.00
What is discount?Discount results in the reduction of the selling price of the product, which makes it more attractive for the customer.
The first discount given is 25% , therefore the price of the bed before mark up is
25/100 × 800
= 25×8
= 200
the price before mark up = 800-200 = $600
Another 25% is given after the first sale, there the price of the bed after mark up is
25/100 × 600
=$ 125
price after markup = 600-125
= $475.00
therefore the price of the bed after markup is $475.00

What is range?Range is a statistical measure that refers to the difference between the highest and lowest values in a set of data. In other words, it is the distance between the largest and smallest values in a dataset.
According to given information:(a) The two dots on the graph at 53 represent two different samples of size 40 that both had a range of 53.
(b) No, the simulation does not provide evidence that the sample range is a biased estimator of the population. A biased estimator systematically overestimates or underestimates the population parameter of interest. The fact that the distribution of sample ranges is approximately symmetric and centered around the true population range suggests that the sample range is an unbiased estimator of the population range. However, the variability of the sample range is quite large, which means that a single sample range may not be a very precise estimate of the population range.

For the right triangle below, find the measure of the angle.
Figure is not to scale.
Answers
For the given right-angled triangle the measure of the angle is 11.30°.
Given adjacent base of the triangle = 10
given opposite side of the triangle = 2
To find out the angle we can use a little bit of trigonometry. By trigonometry, we know that tan ∠ = opposite side / adjacent side.
So, we can use the above tan ∠ relation to find the angle.
Tan ∠ = opposite side / adjacent side
Tan ∠ = 2/10
Tan ∠ = 1/5
∠ = Tan⁻¹(1/5)
∠ = 11.30°.
From the above explanation, we can conclude that the measure of the angle for the given right triangle is 11.30°.

Answers
Without knowing the exact number of turtles in 2005, we cannot determine the exact number of turtles in 2010. However, we can use the information given to set up an equation.
Let x be the number of sea turtles in 2005.
According to the problem, the number of sea turtles in 2010 was twice the amount in 2005, or 2x.
We can set up an equation:
2x = number of sea turtles in 2010
We don't know the exact value of x, so we cannot solve for the number of turtles in 2010.

Answers
The area of the first rectangle is:
20 inches × 15 1/4 inches = 20 × (60/4 + 1/4) = 20 × 61/4 = 20 × 15.25 = 305 square inches
The area of the second rectangle is:
10 1/2 inches × 10 1/4 inches = (10 × 2 + 1/2) × (40/4 + 1/4) = 21 × 41/4 = 21 × 10.25 = 215.25 square inches
Therefore, the total area of construction paper needed for the project is:

A wrestler weighs in on the first day at 162 pounds. To make weight for the first match, the wrestler must lose 1.1 pounds per week. This can be modeled by the equation y=−1.1x+162. Use this model to predict the wrestler’s weight at the first match that is 9 weeks away.
Answers
The wrestler's weight at the first match will be 152.1 pounds. The solution has been obtained by using the substitution method.
What is the substitution method?
The substitution method is a strategy used in algebra to solve simultaneous linear equations. In this process, as the name suggests, the value of one variable from one equation is swapped in the second equation.
We are given that the given situation can be modeled by the equation
y = −1.1x + 162.
Now, we need to find weight at the first match which is 9 weeks away.
So, we get that x = 9.
By substituting this value in the equation, we get
⇒ y = -1.1 (9) + 162
⇒ y = -9.9 + 162
⇒ y = 152.1
Hence, the wrestler's weight at the first match will be 152.1 pounds.

To the nearest ten dollars, what can Carlos expect the value of the computer to be 3 years after purchase
Answers
Carlos can expect the value of the computer to be $580 three years after purchase.
To model the value of the computer, we can use the formula:
y = abˣ
We know that the initial value of the computer is $1,350, so a = 1350.
We also know that one year after purchase, the value of the computer is $810, so we can use this to find the value of b:
810 = 1350b
b= 0.6
b = 0.6
So our exponential equation is:
y = 1350(0.6)ˣ
To find the value of the computer 3 years after purchase, we can substitute x = 3:
y = 1350(0.6)³
y = 583
Hence, Carlos can expect the value of the computer to be $580 three years after purchase.

Navid earns a basic wage of $10.25 an hour. He works for 40 hours a week. He earns 20% more than his basic wage when he works overtime. Navid wants to earn at least $500 this week. Calculate the total number of hours he needs to work. Give your answer to the nearest hour.
Answers
$10.25/hour x 40 hours = $410
To earn at least $500, Navid needs to earn an additional $90 ($500 - $410).
To earn 20% more than his basic wage, Navid would earn:
$10.25/hour x 1.2 = $12.30/hour for each overtime hour
So, Navid needs to work:
$90 ÷ ($12.30/hour - $10.25/hour) = 47.4 hours
Since Navid cannot work a fraction of an hour, he needs to work 48 hours to earn at least $500.
Therefore, Navid needs to work for a total of 40 hours + 8 hours of overtime, which is 48 hours in total (rounded up to the nearest hour).

Answers
Answer:
The expression $11.75x + $20 represents the total price for the order, including delivery to the school.
In this expression, 'x' represents the number of boxes of paints being purchased, and $11.75 represents the cost of each box. The term $11.75x represents the total cost of the boxes of paints based on the number of boxes being purchased.
The term $20 represents the delivery cost to the school, which is added to the total cost of the boxes of paints.
By multiplying the cost per box ($11.75) by the number of boxes (x) and adding the delivery cost ($20), you can calculate the total price for the order, including delivery.

How to solveA graph for straight-line depreciation for a car is given.
a
The number of years the car totally depreciates is 8 years as seen in the graph which is x -intercept.
Step 3/7
The model makes straight-line depreciation. In a straight line depreciation equation, the intercepts are
(0, maximum car value) and (maximum lifespan,0)
Let y represent the value of the car at any time during its lifetime. The minimum y -value is zero dollars and the maximum y -value is the purchase price of $25,600
The intercepts are (0, 25, 600) and (8,0)
Determine the slope of the equation.
Two points determine a line, so only two points are needed to determine the slope of a line.
Let the coordinates of the -intercept be the first point. That is, (xi,yi) = (0, 25, 600)
Let the coordinates of the -intercept be the second point. That is (x2, y2)= (8,0)
Use the slope ratio as shown below;
The slope of the depreciation equation is.
-3200
The general form for the equation of a straight line is:
y = mx + b
Where m represents the slope of the line and b represents the y-intercept.
The slope is -3,200 and the -intercept is 25,600 as obtained.
Therefore, the straight line depreciation equation is:
y = -3,200x + 25,600
Therefore, the value of the car after 4 years is $12,800
b.
Use the depreciation equation and substitute x=5 years to find the car worth after 5 years.
Therefore, the value of the car after 5 years is $9,600
c.
The half value of the car is half of $25,600 which is $12,800
The car will be worth half its original value after 4 years
