The dimensions of the rectangular field with area 120 square meters is 10 meters by 12 meters.
The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
Given perimeter of the rectangular plot is 44 meters.
let the length is x , and width = y
Therefore perimeter = 2 (x + y)
or, 2 (x + y) = 44
or, x + y = 22
or, y = 22 - x
Now the area of the field is given as 120 square meters.
Area of the fields in terms of x is given by:
x ( 22 - x ) = 22 x - x²
Therefore 22 x - x² = 120
or, x² -22x +120 = 0
or, x² - 10x - 12x + 120 = 0
or, x (x -10) -12(x-10)=0
or, (x-10)(x-12) = 0
Now either the value of x is 10m or the value of x is 12m
Therefore the dimensions of the rectangular field is 10 meters by 12 meters.

A quarterback is sacked for a loss of 7 yards. On the next play, his team loses 12 yards. Then the team gains 5 yards
on the third play. Write an expression to represent the word problem. What is the total number of yards lost or gained?
The total number of losses is 14.
What are expressions?In mathematics, an algebraic expression is an expression composed of variables and constants as well as algebraic operations (addition, subtraction, etc.). Terms combine to form expressions.So, let the total number of lost and gains be 'x'.
Then, the expression:
-7 - 12 + 5 = x- 19 + 5 = x-14 = xSo, x has a value that is negative so it is a loss.Therefore, the total number of losses is 14.

The expression that represents the area of the given rectangle is: 2x² - 11x - 6.
How to Find the Area of a Rectangle?The area of a rectangle is the product of its width and its length. A rectangle's area is calculated using the formula below:
Area = (length)(width)
Given the following:
Length of the rectangle = 2x + 1
Width of the rectangle = x - 6
Therefore, substituting these into the formula, we have:
Area of the rectangle = (2x + 1)(x - 6)
Area of the rectangle = 2x(x - 6) +1(x - 6)
Area of the rectangle = 2x² - 12x + x - 6
Combine like terms
Area of the rectangle = 2x² - 11x - 6
Therefore, the expression that represents the area of the given rectangle is: 2x² - 11x - 6.

Answer:
Step-by-step explanation:
you add all of that up and you get your answer then you subtract that answer to 100 then that’s your answer.
Answer:
First what you want to do is start with the socks.
Socks cost $9.00 so if he is buying 3 pair you would multiply by 3.
9 times 3 is 27. = $27
He bought 2 belts and the belts cost $10.00 so you would multiply that by 2.
10 times 2 is 20. = $20
He bought 1 hoodie which amounts to $29.99 and a pair of shoe laces that amounts to $1.50.
Now what you do is add all thew prices together.
$27 + $20 + $29.99 + $1.50 = $78.49
Final, since he is paying with a hundred dollar bill you want subtract that from the total amount.
$100 - #78.49 = $21.51
So he would get back a total of $21.51.

There's a roughly linear relationship between the number of times a species of cricket will chirp in one minute and the temperature outside. For a certain type of cricket, this relationship can be expressed using the formula T=0.33c+38T=0.33c+38, where TT represents the temperature in degrees Fahrenheit and cc represents the number of times the cricket chirps in one minute. What could the number 38 represent in the equation?
The temperature at which the crickets do not chirp is represented by the number 38, which serves as the y-intercept of the linear equation.
The equation is as follows:
T = 38 + 0.3*c
The temperature is denoted by T, while the number of chirps in a minute is denoted by c.
We want to know what the number 38 means.
Take c = 0 to demonstrate this as there are no chirps.
Then:
T = 38 + 0.33*0 = 38
T = 38
This is the temperature where crickets cease to chirp.
The temperature at which the crickets do not chirp is represented by the number 38, which is the y-intercept of the linear equation.

An isolated agricultural country has two distinct regions: a lowland plain and an upland of rugged hills. On one unit of land on the PLAIN, a farmer can raise 10 bushels of grain or graze 10 sheep. On one unit of land in the HILLS, a farmer can raise 2 bushels of grain or graze 4 sheep.
Determine which region has the absolute advantage for sheep production. Explain your answer.
Because food grows more quickly in the hills when exposed to heat and rain rather than sunlight all day. Then for 1 sheep 1 bushel is required in the hills.
What are statistics?
The practice or science of organizing and interpreting numerical data in big quantities, particularly for the objective of concluding proportions in a whole from those in an expected sample.
Given that a remote agricultural nation is divided into two distinct geographic areas: a lowland plain and an upland of rough hills. A farmer can grow 10 bushels of grain or pasture 10 sheep on one unit of land on the plain. A farmer in the hills can pasture 4 sheep or grow 2 bushels of grain on one unit of land.
As opposed to being exposed to sunlight all day, food develops more quickly in the hills when it is exposed to heat and rain.
For uphill = 10 sheep = 10 bushels
For uphill = 1 sheep = 1 bushels
For down plain = 4 sheep = 2 bushels

What is energy?
Energy is described as the "capacity to accomplish work, which is the ability to apply a force that causes an object to move." Despite this perplexing terminology, the meaning is straightforward: energy is just the force that causes objects to move. Potential energy and kinetic energy are the two forms of energy.
Weight = 147 lb = 66.68 kg (since, 1 lb = 0.453 kg)

The equation for the axis of symmetry of the parabola y = - 4 x² + 24 x - 35 is given by x = 3.
We know that the method to find the axis of the symmetry of the parabola is given by:
x = - b / 2 a
We have the general equation of the parabola as:
y = a x² + b x + c
We have the equation of the parabola as:
y = - 4 x² + 24 x - 35
Comparing from this equation, we get that:
a = - 4
b = 24
c = - 35
Now, substituting the values, we get that:
x = - 24 / 2 (- 4)
x = - 24 / - 8
x = 24 / 8
x = 3

In this question we have been given a standard deck of 52 cards.
We need to find the number of ways 5 spades can be drawn from a standard deck of 52 cards without replacement.
We use the permutation formula.
We know that the number of ways to choose r elements from a set of n distinct objects where order does matter and replacements are not allowed.
