Ezra has a square brick patio. he wants to reduce the width by 6 feet and
increase the length by 6 feet.
What is the area of the square?The area of the square is the measure of the space occupied by it. It is equal to the product of the measure of its two sides.
We need to write the expression for the new patio and the area of the new patio if the original patio measures 13 feet by 13 feet.
let x be the measure of the side of a square.
The length increased by 6 ft, so the new length=x+6.
The width decreased by 6 ft, so the new width=x-6.
The area is the product of length and width, so the new area is
l×w = (x+6)×(x-6)
Since the original side is 13 ft, the new length is 13+6 = 19 ft, and the new width is 13-6=7 ft.
So, the area is (19 ft)×(7 ft) = 133 ft²
Hence, the area of the new patio if the original patio measures 13 feet by 13 feet is 133 ft².

A cylindrical pressure vessel has a height of 9 feet and a diameter of 6 feet. how much gas can the pressure vessel hold when full?
it is either, 54 pie cubic feet, 81 pie cubic feet, 108 pie cubic feet or 324 pie cubic feet
Step-by-step explanation:
the volume of a cylinder is as for any other regular 3D object :
ground area ×height
the ground area of a cylinder is a circle, so it is
pi×radius² × height
the radius is always half of the diameter (of the diameter is airways twice the radius).
radius = 6/2 = 3 ft.
the volume is then
pi × 3² × 9 = pi × 9 × 9 = pi × 81 ft³
so, the answer is 81pi ft³.

A family of 4 gets 505 text messages per month. Which of the following best describes the most even way these texts can be divided?
2 family members get 124 text messages each
2 family members get 125 text messages each
2 family members get 126 text messages each
2 family members get 125 text messages each
3 family members get 126 text messages each
1 family member gets 127 text messages
3 family members get 125 text messages each
1 family member gets 126 text messages
Answer:
3 family members get 126 text messages each
1 family member gets 127 text messages
Step-by-step explanation:
If you were finding the exact division of texts, 505 texts / 4 people, you would end up with 126.25 texts.
However, you can't get 0.25 of a text. If we take back each family member's 0.25 text, they will all be left with 126 texts (with an extra text leftover)
This extra text is considered the "remainder", meaning the amount left over when a number is divided [when it doesn't go into the larger number evenly]. The only importance/relevancy of a remainder is when a value cannot be split, such as a dog or a text.
So, we can give each family member 126 texts, and then we can give one family member an additional text, so that all texts are distributed.
This means that 3 family members get 126 texts, and 1 family member gets 127 texts

The statements that are true for Trapezoid WXYZ are:
Line WZ has the same slope as line XY.Line XW has a lesser slope than line YZ.Line ZW has the same y-intercept as line WZ.Line XY has a greater y-interceptHow to Interpret Line Coordinates?
We are told that;
Shape is a trapezoid WXYZ.
Now, In a trapezoid, one pair of opposite sides are parallel and parallel lines have the same slope.
Lastly, the slope of line parallel to x axis is 0 and so If the line starts at the bottom left and goes towards the top right it has negative slope. Thus, all the statements that are true for Trapezoid WXYZ are:
Line WZ has the same slope as line XY.Line XW has a lesser slope than line YZ.Line ZW has the same y-intercept as line WZ.Line XY has a greater y-interceptComplete question is;

To sell 300 notebooks and 120 pens quickly, a store decided to create two types of gift sets. one set is to include 2 notebooks and 1 pen, and the other will consist of 1 pen and 3 notebooks. the first set will be sold for $8, while the second will be sold for $11.50. it is unprofitable to sell more than 20 of any gift set. how many gift sets of each type must the store sell to obtain the biggest possible income?
The store must sell 60 of each set each to obtain the biggest possible income
How to determine the number of each gift set?The given parameters can be represented using the following table:
Set 1 Set 2 Available

Answer:
[tex]3n^2+3n-6=54[/tex]
Step-by-step explanation:
Total Area=54 square inches. Area=length*width.
Because the length is [tex][3(n-1)][/tex], and the width is [tex](n+2)[/tex], you can plug that into the equation for area. In this case, because the total area is 54, we can plug that in for area.
[tex][3(n-1)](n+2)=54[/tex]
Distribute through the parenthesis in [tex]3(n-1)[/tex].
[tex](3n-3)(n+2)=54[/tex]
Then, multiply [tex]3n-3[/tex] and [tex]n+2[/tex] using whatever method you prefer. I used FOIL, which stands for First, Outer, Inner, Last. You multiply the first terms together, the outer terms together, the inner terms together, and the last terms together.
