The regular price on a pair of jeans is $54. The store advertises a back to school sale at 40% of the regular price of the jeans. Two weeks later, the store advertises a sale at an additional 20% off the sale price of the jeans. Two friends decided to purchase the jeans. Shannon says these jeans are now 60% of the regular price. Mary disagrees because she figures that the total discount is less than 60%. What is the cost of the jeans at the 40% off back-to-school sale. What is the cost of the jeans during the additional 20% off sale.
Answer:

the measure of the larger angle is 12 less than 3 times the measure of the smaller angle
Answer:
Let x be the measure of the smaller angle. Then the measure of the larger angle is 3x - 12.
We can write this as an equation:
larger angle = 3 * smaller angle - 12 or 3x - 12 = larger angle.
Alternatively, we can write it as:
smaller angle + larger angle = 180 (since they form a straight line)
Substituting larger angle with 3x - 12, we get:
x + 3x - 12 = 180
Simplifying:
4x - 12 = 180
4x = 192
x = 48
Therefore, the measure of the smaller angle is 48 degrees, and the measure of the larger angle is 3(48) - 12 = 132 degrees.
The measure of the larger angle is 12 less than 3 times the measure of the smaller angle x = 48
What is angle?An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’ meaning “corner.”
Angles can mean is an acute angle.
Let smaller angle = x
Larger angle = 3x - 12
x & (3x - 12) are supplementary
So, x + 3x - 12 = 180°
4x - 12 = 180
4x = 180 +12
4x = 192
x = 192/4
⇒ x = 48°
Hence, the measure of the larger angle is 12 less than 3 times the measure of the smaller angle x = 48

Andre calculated the volume of a cylinder. Andre said, “I found the area of a circular cross section and multiplied it by the cylinder’s height.”
Do you agree with Andre's strategy? Explain your reasoning.
Yes, I agree with Andre's strategy for calculating the volume of a cylinder.
The volume of a cylinder is equal to the area of the base (which is a circle) multiplied by the cylinder's height. This formula is expressed as follows:
Volume = r2h, where r is the radius of the circular base and h is the cylinder's height.
We can use the following formula to calculate the area of the circular base:
Area = r2
So, if we multiply the area of the circular base by the cylinder's height, we get:
Volume = r2h is the formula for calculating the volume of a cylinder.
As a result, Andre's strategy of calculating the volume of a cylinder by finding the area of a circular cross section and multiplying it by the height of the cylinder is valid and correct.

A maintenance worker needs to wax a restaurant floor shaped like the image shown. A six-sided figure. There is a horizontal base of 35 feet then another horizontal base below it of 20 feet. The longest side is to the right and is 40 feet. The top is 30 feet. There is a perpendicular from the vertex of the top to the first base of 35 that is labeled 15 feet. If the wax cost $1.38 a square foot, how much will the wax cost to cover the floor? $1,224.75 $1,569.75 $2,104.50 $2,449.50
If the wax cost $1.38 a square foot, the cost of wax to cover the area of the floor is $1,569.75.
The correct option is B.
What is the total area of the floor?The total area of the floor is calculated from the shape of the floor.
The floor is made up of a trapezoid and a rectangle.
The area of a trapezoid can be calculated as:
A = (a + b)/2 * h
where
a and b are the lengths of the bases and h is the height.
The trapezoid has a height of 15 feet and bases of 35 feet and (20 - 20) or 10 feet. So its area is:
A = (35 + 10)/2 * 15
A = 337.5 square feet
The rectangle has a base of 20 feet and a height of 40 feet. So its area is:
A =20 * 40
A = 800 square feet
The total area of the figure is the sum of the areas of the trapezoid and triangle:
A = 337.5 + 800
A = 1137.5 square feet
Finally, to find the cost of the wax, we multiply the area by the cost per square foot:
Cost = 1137.5 * $1.38
Cost = $1569.75
