A notebook has a perimeter of 36 inches. It’s area is 80 square inches. What are the dimensions of the notebook
__inches by___ inches
Final answer:
To solve for the dimensions of the notebook, we set up equations based on the perimeter and area, then solved the quadratic equation to find that the dimensions are 10 inches by 8 inches.
Explanation:
To find the dimensions of a notebook with a perimeter of 36 inches and an area of 80 square inches, we will use the formulas for the perimeter and area of a rectangle. The perimeter (P) of a rectangle is 2 times the length (l) plus 2 times the width (w), or P = 2l + 2w. The area (A) of a rectangle is length times width, or A = lw.
Given P = 36 and A = 80, we can set up two equations:
2l + 2w = 36l × w = 80First, we simplify the perimeter equation to l + w = 18 by dividing everything by 2. We can then express w in terms of l: w = 18 - l. Now, we substitute w into the area equation: l(18-l) = 80. Expanding this gives us a quadratic equation: l2 - 18l + 80 = 0.
To solve the quadratic equation, we look for factors of 80 that add up to 18. The factors are 10 and 8, meaning the length is 10 inches and the width is 8 inches, since l = 10 and w = 8 satisfy both the area and perimeter equations.
Therefore, the dimensions of the notebook are 10 inches by 8 inches.

If a map shows the straight line distance between two cities as 3 1/2 centimeters and the map scale shows that 1 centimeteer equals 100 kilometers what would the actual distance be
Answer:
The actual distance between the two cities is 350 kilometers
Step-by-step explanation:
Information given to us to answer the question correctly:
Distance between two cities in the map = 3 1/2 centimeters
Scale of the map: 1 centimeter = 100 kilometers
2. What would the actual distance be?
Let's calculate the actual distance between the two cities, this way:
Actual distance = Distance between two cities in the map * Scale of the map
Replacing with the real values:
Actual distance = 3.5 * 100
Actual distance = 350 kilometers
Use the mid-point rule with n = 4 to approximate the area of the region bounded by y = x3 and y = x. (10 points)
Using the mid-point rule with n = 4, we approximate the area bounded by y = x³ and y = x b as 0.2578125.
To approximate the area of the region bounded by y = x³ and y = x using the mid-point rule with n = 4, we follow these steps:
Determine the points of intersection between y = x³ and y = x. Solving x³ = x, we get the points of intersection at x = 0 and x = 1.
Divide the interval [0, 1] into 4 subintervals, each of width Δx = (1 - 0)/4 = 0.25.
Calculate the midpoint of each subinterval: 0.125, 0.375, 0.625, and 0.875.
Evaluate the functions y = x³ and y = x at these midpoints:
At x = 0.125: y = x³ = 0.125³ = 0.001953125 and y = x = 0.125At x = 0.375: y = x³ = 0.375³ = 0.052734375 and y = x = 0.375At x = 0.625: y = x³ = 0.625³ = 0.244140625 and y = x = 0.625At x = 0.875: y = x³ = 0.875³ = 0.669921875 and y = x = 0.875Determine the heights of the rectangles by finding the difference between the values of y:
At x = 0.125: Δy = 0.125 - 0.001953125 = 0.123046875At x = 0.375: Δy = 0.375 - 0.052734375 = 0.322265625At x = 0.625: Δy = 0.625 - 0.244140625 = 0.380859375At x = 0.875: Δy = 0.875 - 0.669921875 = 0.205078125Compute the area of each rectangle (height × width) and then sum them up:
Area at x = 0.125: 0.123046875 × 0.25 = 0.03076171875Area at x = 0.375: 0.322265625 × 0.25 = 0.08056640625Area at x = 0.625: 0.380859375 × 0.25 = 0.09521484375Area at x = 0.875: 0.205078125 × 0.25 = 0.05126953125Add the areas to get the total approximate area:
0.03076171875 + 0.08056640625 + 0.09521484375 + 0.05126953125 ≈ 0.2578125
Therefore, the approximate area of the region bounded by y = x³ and y = x using the mid-point rule with n = 4 is 0.2578125.

He used the wrong values as the bases of the lateral faces.
He used the wrong expression to represent the area of the base of the pyramid.
He used two different values as the heights of the lateral faces. NOT C
He used an expression for surface area that did not include all the faces.
PLZZ HELP
the answer is A. hope this helps!!!!
The error that Gio is making in finding the surface area of the rectangular pyramid is that He used an expression for surface area that did not include all the faces.
What is Surface Area?The area of a three dimensional object on it's outer surface is called the surface area of the object.
Given a rectangular pyramid.
Pyramid consists of one rectangular side and 4 triangular faces of which each pair of triangular faces is identical.
Total surface area of the pyramid is the total surface area of each faces.
Area of rectangular face = (4.2) (9.6)
Area of the triangular faces = [2 × 1/2 × 4.2 × 6.5] + [2 × 1/2 × 9.6 × 4.8]
= (4.2) (6.5) + (9.6) (4.8)
Total area = (4.2) (9.6) + (4.2) (6.5) + (9.6) (4.8)
So his mistake is that he only find the areas of two triangular faces.
Hence the correct option is that He used an expression for surface area that did not include all the faces.

What is the equation of a circle with center (8, 4) and radius 7?
The standard form of the equation of a circle is given by (x-h)² + (y-k)² = r², where (h, k) are the center and r is the radius. For a circle with center at (8, 4) and radius 7, the equation of the circle becomes (x - 8)² + (y - 4)² = 49.
Explanation:The equation of a circle in standard form is given by (x-h)² + (y-k)² = r², where (h, k) are the coordinates of the center of the circle and r is the radius. This formula comes from Pythagorean theorem and how a circle is defined as the locus of points equidistant from a given point (the center).
By substituting the given center and radius into this formula, we can write the equation of the specific circle you're asking about. The center of this circle is (h, k) = (8, 4), and its radius is r = 7. Therefore, the equation of the circle is (x - 8)² + (y - 4)² = 7² or (x - 8)² + (y - 4)² = 49.
