to under stand this think of a rectangle, or square. that's the yard, then
we know the total area of that rectangle or square, some how. :/ they just tell us, then they tell us the length , or one side of our rectangle or square.
we just have to find the other side.
area of yard (rectangle) = Length * Width
area = L * W
81 = 12 * W
use your algebra skills... ( my calculus prof. tells us that we are all bad at it :))
81/12 = W
6.75 = W
the width of the yard is 6.75 meters

The answer is 41
Step-by-step explanation:
To solve this we must use the formula a^2+b^2=c^2. if we substitute in the values we get 9^2+40^2=c^2. The first variable is 81, then the b variable is 1600. The hypotenuse is the c value. 81+1600 is 1681, now we must find the square root of 1681. The answer is 41. Tell me if I'm wrong :)

What is a prime polynomial?An irreducible polynomial is a polynomial (of degree greater than zero) that cannot be factored into polynomials of lower degrees. The irreducibility property depends on the nature of the coefficients that are accepted for the possible factors, that is, the field or ring to which the coefficients of the polynomial and its possible factors should belong.
In this way we have that:

10 in
Answers
Answer: 800
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
The surface area of the figure is 40 + 5π.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:

We have,
From the figure,
We have a semicircle and a rectangle.
Now,
Diamter = 10 in
Radius = 5 in
Circumference = 2πr
Semicircle circumference = πr
Now,
The surface area of the figure.
= 15 + 10 + 15 + πr
= 40 + 5π
Thus,
The surface area of the figure is 40 + 5π.

The value of the missing number x will be 10.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Let the missing number be x. Then the equation can be written as,
3 + 7 + 2 = x + 2
Simplify the equation, then the value of the variable x will be
3 + 7 + 2 = x + 2
3 + 7 + 2 - 2 = x
x = 3 + 7
x = 10
The value of the missing number x will be 10.

A performing arts group has 23 members and adds 2 members per
month. Write an equation in slope-intercept form to represent the number
of members y in x months.
Answers
y=2x+23
2x is the for the number of people added every month and 23 is for the number you start with
The equation in slope-intercept form to represent the number of members y in x months is : y = 2x + 23
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
In slope-intercept form, an equation of a line is represented as y = mx + b, where m is the slope (or rate of change) and b is the y-intercept (or the point at which the line crosses the y-axis).
Let's represent x is the number of months and y is the number of members.
The number of members y in x months is a linear function of the number of months, with a slope of 2 (the number of members added per month) and a y-intercept of 23 (the number of members at the beginning).
Thus, the equation in slope-intercept form to represent the number of members y in x months is : y = 2x + 23
