Answer:
Option C. $1.67
Step-by-step explanation:
The price of a bag of candy at wholesale = $1.15
The markup on candy at the discount store = 45%
The retail price for the candy = 1.15 +(45% × 1.15)
= 1.15 + ([tex]\frac{45}{100}[/tex]×1.15)
= 1.15 + (0.45 × 1.15)
= 1.15 + 0.5175
= 1.6675 ≈ $1.67
The retail price for the candy would be $1.67.

Given the two equations below, determine which statement best describes the graph of the equations.
y=1/2x-3
y=-2x+16
Select answer A The two lines given by the above equations are perpendicular. Select answer
B The two lines given by the above equations coincide. Select answer
C The two lines given by the above equations are parallel.
D The two lines given by the above equations intersect (but are not perpendicular). ...?
Answer: Option A.
Step-by-step explanation:
The lines that we have is:
y = (1/2)x - 3
y = -2x + 16
Now, two lines of the shape y1 = a1*x + b1 and y2 = a2*x + b2 are parallel if both lines have the same slope, this means that a1 = a2.
Those lines are perpendicular if a1 = -1/a2
now, the slope in the first equation is (1/2) and in the second equation is -2.
so a1 = 1/2
-1/a1 = -(2) = a2
so the two lines are perpendicular, the correct option is A

A bedroom set lists for $12,000 and carries a trade discount of 30 percent. Freight (FOB shipping point) of $150 is not part of list price. Calculate the delivered price of the bedroom set including the freight. Assume a cash discount of 2 percent:
A new savings account is opened with $300 and gains 3.1% yearly for 5 years
At the end of 5 years, with the 3.1% interest rate, your savings account will grow to $349.47.
Use the concept of percentage defined as:
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means.
Given that,
A new savings account is opened with $300.
The account earns a 3.1% interest rate per year.
The interest is calculated yearly.
The duration of the investment is 5 years.
After the first year,
Savings will increase by 3.1% of $300, which is $9.30.
So, your balance at the end of the first year will be $309.30.
For the following years,
you will continue to earn 3.1% interest on the new balance each year. Here's a breakdown of your balance at the end of each year:
Year 1: $309.30
Year 2: $309.30 + 3.1% of 309.30 = $318.88
Similarly
Year 3: $328.77
Year 4: $338.96
Year 5: $349.47
Hence,
At the end of 5 years, with the 3.1% interest rate, your savings account will grow to $349.47.

4. Which of the following sets of numbers is a Pythagorean triple?
A. 4, 5, 6
B. 8, 15, 17
C. 5, 12, 14
D. 8, 24, 25
Suppose a triangle has side lengths 6, 7, and 10. Which of the following best describes this triangle?
A. obtuse
B. acute
C. right
D. Cannot be determined.
The set 8, 15, 17 is a Pythagorean triple because 8^2 + 15^2 = 17^2. A triangle with sides of 6, 7, and 10 is an obtuse triangle, because 10^2 > 6^2 + 7^2.
Explanation:The set of numbers, 8, 15, 17, represents a Pythagorean triple. A Pythagorean triple consists of three positive integers a, b, and c, such that a^2 + b^2 = c^2. In this case, 8^2 + 15^2 = 64 + 225 = 289, and 17^2 = 289, so the equation is satisfied.
Furthermore, a triangle with sides 6, 7, and 10 would be described as obtuse. In any triangle, if the square of the length of the longest side is greater than the sum of the squares of the other two sides, then the triangle is obtuse. Thus, if 10^2 > 6^2 + 7^2, or 100 > 36 + 49, then the triangle is obtuse. Since this statement holds true, the triangle is indeed obtuse.

The correct options are: B. 8, 15, 17 and A. obtuse
We can use the Pythagorean theorem to determine which set of numbers is a Pythagorean triple. The theorem states that in a right triangle, the square of the hypotenuse (c) equals the sum of the squares of the other two sides (a and b): a2 + b2 = c2.
Option A: 4, 5, 6: [tex]4^2 + 5^2 = 16 + 25 = 41[/tex], and [tex]6^2=36[/tex], which is not equal to 41.Option B: 8, 15, 17: [tex]8^2 + 15^2 = 64 + 225 = 289[/tex], and [tex]17^2=289[/tex], equal.Option C: 5, 12, 14: [tex]5^2 + 12^2 = 25 + 144 = 169[/tex], and [tex]14^2=196[/tex], which is not equal to 169.Option D: 8, 24, 25: [tex]8^2 + 24^2 = 64 + 576 = 640[/tex], and [tex]25^2=625[/tex], which is not equal to 640.The correct Pythagorean triple is 8, 15, 17.
To determine the type of triangle with side lengths 6, 7, and 10, we use the idea that for a triangle with sides a, b, and c (where c is the longest side):
If [tex]c^2 = a^2 + b^2[/tex], the triangle is right.If [tex]c^2 < a^2+b^2[/tex], the triangle is acute.If [tex]c^2 > a^2+b^2[/tex], the triangle is obtuse.For the triangle with sides 6, 7, and 10:
[tex]6^2+7^2=36+49=85[/tex] and [tex]10^2=100[/tex].
Since 100 > 85, the triangle is obtuse.
A box has dimensions of 17 inches long, 1.3 feet wide, and 8 inches high. What is the volume of the box? The formula for the volume is V = l w h. (1 point)
2121.6 cubic inches (in3)
176.8 cubic inches (in3)
14.7 cubic inches (in3)
1.2 cubic inches (in3)
To find the volume of the box, convert all units to inches, then apply the formula for the volume of a rectangular prism, resulting in 2,121.6 cubic inches.
Explanation:To calculate the volume of the box with dimensions given in inches and feet, we first need to convert all units to the same system. Since the width is given in feet (1.3 feet), we convert it to inches knowing that 1 foot equals 12 inches. Thus, 1.3 feet is equal to 1.3 × 12 = 15.6 inches.
To find the volume of the box, you need to multiply the length, width, and height together:
Convert the dimensions to a consistent unit, such as inches.
Calculate: 17 inches x 1.3 feet x 8 inches = 176.8 cubic inches.
Therefore, the volume of the box is 176.8 cubic inches (in3).
Now, with all dimensions in inches: the length is 17 inches, the width is 15.6 inches, and the height is 8 inches. Applying the formula for the volume of a rectangular prism, V = l × w × h, we get:
V = 17 inches × 15.6 inches × 8 inches = 2,121.6 cubic inches.
Therefore, the correct option is 2121.6 cubic inches (in3).
make x the subject 6x+a=5(x+t)
To make x the subject of the equation, you can rearrange the equation x = 5t - a.
Explanation:To make x the subject of the equation, we need to isolate the variable on one side of the equation. Here's how:
Distribute 5 to both x and t: 6x + a = 5x + 5tSubtract 5x from both sides: 6x - 5x + a = 5tCombine like terms: x + a = 5tSubtract a from both sides: x + a - a = 5t - aCancel out a: x = 5t - aTherefore, to make x the subject, the equation is x = 5t - a.

A school system is reducing the amount of dumpster loads of trash removed each week. In week 5, there were 45 dumpster loads of waste removed. In week 10, there were 30 dumpster loads removed. Assume that the reduction in the amount of waste each week is linear. Write an equation in function form to show the amount of trash removed each week.
f(x) = - 3x + 45
f(x) = 3x + 45
f(x) = - 3x + 60
f(x) = 3x + 60
The correct answer is:
[tex]\[\boxed{f(x) = -3x + 60}\][/tex]
To find the linear equation representing the amount of trash removed each week, we need to determine the slope and the y-intercept.
Given:
- In week 5, there were 45 dumpster loads.
- In week 10, there were 30 dumpster loads.
Step 1: Calculate the Slope
The slope m of a line is calculated by:
[tex]\[m = \frac{y_2 - y_1}{x_2 - x_1}\][/tex]
Here,[tex]\((x_1, y_1) = (5, 45)\) and \((x_2, y_2) = (10, 30)\).[/tex]
[tex]\[m = \frac{30 - 45}{10 - 5} = \frac{-15}{5} = -3\][/tex]
Step 2: Write the Equation in Point-Slope Form
Using the point-slope form of the equation [tex]\( y - y_1 = m(x - x_1) \):[/tex]
[tex]\[y - 45 = -3(x - 5)\][/tex]
Step 3: Convert to Slope-Intercept Form [tex]( \( y = mx + b \) )[/tex]
Simplify the equation:
[tex]\[y - 45 = -3(x - 5)\][/tex]
[tex]\[y - 45 = -3x + 15\]\[y = -3x + 15 + 45\]\[y = -3x + 60\][/tex]
Thus, the equation in function form that shows the amount of trash removed each week is:
[tex]\[f(x) = -3x + 60\][/tex]
Therefore, the correct answer is:
[tex]\[\boxed{f(x) = -3x + 60}\][/tex]

NOTICE: Edge loves moving things around SO IT MIGHT NOT BE C FOR YOU But its fore sure 74
Final answer:
Mr. Thom can put $59 per week towards emergency savings.
Explanation:
To find the total amount that Mr. Thom can put towards emergency savings per week, we need to calculate the difference between his total paycheck and the sum of his weekly deposits into the other accounts. From the given information, his total paycheck is $498, and the sum of his weekly deposits into the other accounts is $219 + $115 + $40 + $10 + $40 + $15 = $439. We can subtract the sum of the weekly deposits from the total paycheck to find the difference, which is $498 - $439 = $59. This is the amount that Mr. Thom can put towards emergency savings per week.
