A rectangle has perimeter 70 inches, and its area is 286 sq-inches. Find the dimensions of this
rectangle. (For purposes of this problem only, the width is shorter than the length.)
length =

inches
inches
Enter your answers as numbers. If necessary, round to the nearest hundredths.
Thus, the dimensions of the rectangle are - length 22 inches and width 13 inches.
Explain about the rectangle:An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). The opposite sides of a rectangular are equal and parallel. A rectangle has two dimensions—length and width—because it is a two-dimensional form. The rectangle's longer side is its length, while its shorter side is its breadth.
Let the length of rectangle be 'l'
Let the width be 'w'.
Then,
Perimeter = 2(l + w)
70 = 2(l + w)
35 = l + w
l = 35 - w ...eq 1
Now,
Area = length * width
286 = l*w ...eq 2
Put eq 1 in eq 2
286 = (35 - w)*w
286 = 35w - w²
w² - 35w + 286 = 0
Solving the quadratic equation:
w² - 22w - 13w + 22*13 = 0
w(w - 22) - 13(w - 22)= 0
(w - 22)(w - 13) = 0
w = 22 and w = 13
As, length is greater than width-
width w = 13 inch
Length l = 35 - 13 = 22 inches.

To find the length of a row of bookshelves, we can use the square root function, as the length of a row of bookshelves will be proportional to the square root of the area of the space that Isabel rents.
Mathematically, we can express f(x) as: f(x) = √(x)
Where x represents the area of the space that Isabel rents, and f(x) represents the total length of a row of bookshelves.
What is the square root function?The above function takes the square root of the area x, which gives us the length of a row of bookshelves in feet, assuming that the area is in square feet. As x increases, f(x) will also increase, indicating that the length of the row of bookshelves will also increase as Isabel rents a larger area in the warehouse.
To find the length of a row of bookshelves, we can use the square root function, denoted as √(x), where x represents the area of the space that Isabel rents.
Determine the area of the space that Isabel rents, denoted as x. This could be obtained from the rental agreement or by measuring the area of the space using appropriate units (e.g., square feet).Take the square root of x using a calculator or by using a mathematical formula. The square root of x, denoted as √(x), represents the positive value which, when multiplied by itself, gives x.The resulting value of √(x) represents the total length of a row of bookshelves in feet (assuming that the area is in square feet), as per the requirement given in the problem statement.For example, if Isabel rents an area of 324 square feet, we can find the length of a row of bookshelves as follows:
x = 324
f(x) = √(x) = √(324) = 18
So, the length of a row of bookshelves would be 18 feet in this case.

A wildlife group is trying to determine how many wild hogs are in a certain area. They trapped, tagged, and released 20 wild hogs. Later, they counted 8 wild hogs out of the 40 they saw.
What can the wildlife group estimate is the total population of wild hogs in that area?
A. 80
B. 90
C. 100
D. 16
Answer choice C is correct. That is the total population of wild hogs in that particular area is 100.
What do you mean by total population in a area?Total population in an area refers to the number of individuals of a particular species or group living in a specific geographical region or habitat. This can include both visible and hidden individuals, such as animals that are difficult to spot or track. Total population is an important measure for conservation and management efforts, as it helps determine the size of a population and whether it is growing or declining.
Given that 20 wild hogs were tagged and later they saw 8 tagged wild hogs out of 40 recaptured wild hogs. We need to find the total population of wild hogs in that area.
From the given information we can see,
(Number of hogs tagged) / (Total population) = (Number of tagged hogs recaptured) / (Number of hogs recaptured)
⇒ 20 / x = 8 / 40
⇒ 8x = 20 × 40
⇒ 8x = 800
⇒ x = 100
Therefore, the wildlife group can estimate that the total population of wild hogs in the area is 100.

Find the volume of the two prisms.
someone pls help me I need to ace this test
Therefore, the total volume of the two prisms is 10,404 cubic inches.
What is volume?Volume is a measure of the amount of space occupied by a three-dimensional object. It is typically measured in cubic units, such as cubic meters (m³), cubic feet (ft³), or cubic centimeters (cm³). The volume of an object is calculated by multiplying its length, width, and height or by using an appropriate formula for the shape of the object.
Here,
The two prisms have the same dimensions of 17 inches in height, 18 inches in base, and 17 inches in length and width.
To find the volume of a prism, we multiply the area of the base by the height. The base of the prism is a rectangle with length 18 inches and width 17 inches, so the area of the base is:
Area of base = length × width
= 18 in × 17 in
= 306 in²
Therefore, the volume of one prism is:
Volume = area of base × height
= 306 in² × 17 in
= 5202 in³
The volume of the two prisms combined is simply twice the volume of one prism:
Total volume = 2 × 5202 in³

How many bucket loads would it take to bucket out the world’s ocean
Answer:
Impossible to know, or best guess
Step-by-step explanation:
It is impossible to determine exactly how many bucket loads it would take to empty the world's ocean because the volume of the ocean is constantly changing due to factors such as tides, currents, and sea level rise. However, we can estimate the approximate volume of the ocean and calculate the number of bucket loads needed based on that estimate.
The approximate volume of the world's ocean is 1.332 billion cubic kilometers (km³) or 332.5 million cubic miles (mi³). Assuming that each bucket can hold 10 liters or 0.01 cubic meters (m³) of water, we can calculate the number of bucket loads needed to empty the ocean as follows:
1 km³ = 1,000,000,000 m³
1,332,000,000 km³ = 1.332 x 10¹⁸ m³
1.332 x 10¹⁸ m³ / 0.01 m³ per bucket = 1.332 x 10²⁰ bucket loads
Therefore, it would take approximately 1.332 x 10²⁰ or 133,200,000,000,000,000,000 bucket loads to empty the world's ocean. This number is so large that it is practically impossible to even visualize, let alone accomplish.

A group of students was to clean up to two areas in their school. area a was 1 1 2 times of area b. in the morning (half of a day), the number of students cleaning area a was 3 times that of the number of students in area b. in the afternoon (another half of a day), 7/12 of the students worked in area a while the rest of them in area b. at the end of the day, area a was done, but area b still needed 4 students to work one more day before it was done. how many were there in this group of students?
There were 24 students working in area B in the morning, and 3 times as many, or 72 students, working in area A. The total number of students is then 24 + 72 = 96.
What is an area?In geometry, an area is the measurement of the amount of space inside a two-dimensional flat surface such as a square, rectangle, triangle, circle, or any other shape. It is usually expressed in square units, such as square centimeters (cm²) or square meters (m²), and is calculated by multiplying the length and width of a rectangular shape or by using specific formulas for different geometric shapes such as the base times the height divided by 2 for a triangle or pi times the radius squared for a circle. The concept of area is fundamental in many branches of mathematics, physics, engineering, and other fields where the measurement of the extent of a surface is important.
According to the given equationLet's assume that the number of students working in area b is x. Then the number of students working in area A is 3x (since there are three times as many students working in area A as in area b in the morning).
Let A be the area of area a, and B be the area of area b. We know that A = 1.5B (since area a is 1 1 2 times the area of area b).
In the morning, the total number of students is x + 3x = 4x.
In the afternoon, 7/12 of the students work in area a, and the rest work in area b. So, the number of students working in area A in the afternoon is 7/12 * 4x = 7x/3, and the number of students working in area b is (1 - 7/12) * 4x = 5x/12.
Since area a was finished at the end of the day, we know that the total area cleaned by the students is A + B = 1.5B + B = 2.5 B. This means that the number of students working in area b is enough to finish 0.5B (since area a was already finished), but 4 more students are needed to finish the remaining 0.5B.
So, we can set up the following equation:
(5x/12) / x = 0.5 / (0.5 + 4/x)
Simplifying this equation, we get:
5x = 6x + 24
x = 24
Therefore, there were 24 students working in area b in the morning, and 3 times as many, or 72 students, working in area A. The total number of students is then 24 + 72 = 96.
