The original blanket was a square with side 31 inches both in length and width. After adding 1 foot to one side, and subtracting 4 inches from the other, new dimensions are 43 inches and 27 inches, respectively. Thus, the new area of the blanket is 1161 square inches.
Explanation:To solve this problem, we first need to note that the area of a rectangle (which our blanket has now become) is the product of its length and width. Since Kiara's blanket was originally a square before she added 1 foot to one side (12 inches) and subtracted 4 inches from the adjacent side, the original side length was the square root of the given area, i.e., √960 inch² = 31 inch. So, one dimension after alteration is 31 inches + 12 inches = 43 inches, and the other (after cutting) is 31 inches - 4 inches = 27 inches. Therefore, the new area of the blanket is 43 inches x 27 inches which equals 1161 square inches.

The area of the original blanket is 784² square inches
Let's denote the side length of the original square blanket as 'x' inches.
After adding 1 foot (12 inches) to one side, the length of that side becomes x + 12 inches.
After cutting 4 inches off from an adjacent side, the length of that side becomes x - 4 inches.
We are given that the area of the resulting blanket is 960 square inches. This can be expressed as:
(x + 12)(x - 4) = 960
Expanding the left side of the equation, we get:
x^2 + 8x - 48 = 960
Adding 48 to both sides of the equation, we get:
x^2 + 8x = 1008
Dividing both sides of the equation by x, we get:
x + 8 = 1008/x
Solving for x using a quadratic equation solver or by trying out different values, we find that x ≈ 28.
Therefore, the area of the original square blanket is:
x^2 = 28^2 = 784 square inches

a square field has an area of 2000 square feet. to the beat fest foot, how much fencing would be needed to enclose the field
Answer:
180 feet
Step-by-step explanation:
√2000 = 44.8
44.8 x 4 = 179.2 = 180 feet
The amount of fencing that would be needed to enclose this square field is 178.88 feet.
A square field would have both the length and the width being equal both of them could be represented as x.
Area of a square = Length x Width
2,000 = x × x
x² = 2,000
x = √2,000
x = 44.72 feet
The fencing needs to go around the field which means it needs to go around the field's perimeter.
Perimeter of Square = Length x 4
= 44.72 x 4
= 178.88 feet
In conclusion, 178.88 feet of fencing would be needed.

A computer cost £900. It is on sale for 25% off. You also need to pay 6% sales tax. What is the final price of the computer?
First we have to find 25% of 900 pounds (i hope that's the right currency). so 900 x .25 = 225
so we subtract 225 from 900 and get 675 pounds.
to find sales tax we have to find 6% of 675, so 675 x .06 = 40.50
675 + 40.50 = 715.5 pounds
The difference between the two roots of the equation 3x2+10x+c=0 is 4 2/3 . Find the solutions for the equation.
Answer:
x1 = - 4
x2 = 2/3
Step-by-step explanation:
Divide the equation by 3 to give
x^2 + 10x/3 + c/3 = 0
The sum of the two roots = - 10/3
So
x1 + x2 = -10/3
x1 - x2 = 4 2/3 Add these two equations.
2x1 = -10/3 + 4 2/3 Change 4 2/3 to an improper fraction
2x1 = -10/3 + 14/3 Combine the right
2x1 = 4/3 Divide by 2
2x1/2 =4/3//2
x1 = 2/3
=====================
x1 + x2 = - 10/3
2/3 + x2 = - 10/3
x2 = - 10/3 - 2/3
x2= -12/3
x2 = - 4
=================
(x - 2/3)(x +4) = 0 Multiply through by 3
(3x - 2)(x + 4) =0

Write the equation of the line in slope-intercept form using the two points: E(-1, 3) and F(-2, -3).
Answer:
[tex]\large\boxed{y=6x+9}[/tex]
Step-by-step explanation:
The slope-intercept form of the equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points E(-1, 3) and F(-2, -3). Substitute:
[tex]m=\dfrac{-3-3}{-2-(-1)}=\dfrac{-6}{-2+1}=\dfrac{-6}{-1}=6[/tex]
Therefore the equation of a line is:
[tex]y=6x+b[/tex]
Put the coordinates of the point E(-1, 3) to the equation and solve it for b:
[tex]3=6(-1)+b[/tex]
[tex]3=-6+b[/tex] add 6 to both sides
[tex]9=b\to b=9[/tex]

13 = 6 + y
13 - 6 is 7
7 + 6 = 13
Just subtract the 2 numbers and you get your answer.
Final answer:
The equation 13 = 6 + y is solved by subtracting 6 from both sides, yielding y = 7.
Explanation:
To solve for y in the equation 13 = 6 + y, we need to isolate y on one side of the equation. We can do this by subtracting 6 from both sides of the equation.
Here is how you can solve the equation step by step:
Start with the original equation: 13 = 6 + y.
Subtract 6 from both sides: 13 - 6 = 6 + y - 6.
This simplifies to: 7 = y.
So, the value of y is 7.

Answer: OPTION D.
Step-by-step explanation:
The symbol of the inequality ">" means "greater than". Then, -5 is greater than -6.
If a negative number -a is greater than other negative number -b , then the distance between -a and zero is shorter than the distance between -b and zero.

1 V
2 Ns
1 T
Possible positions:
For the S, any one of the nine positions. That's ⁹C₁ positions.
For the Es, any four of the remaining eight positions. That's ⁸C₄ positions.
For the V, any one of the remaining four positions. That's ⁴C₁ positions.
For the N, any two of the remaining three positions. That's ³C₂ positions.
For the T, only one way to fill the last position. That's ¹C₁ position.
Total number of positions

Step-by-step explanation:
if the circle's surface area is 89 square feet. The circle's radius will then be 5.32 feet.
What is the area of a circle?It is the closely curving line drawn from the center to an equally distant point. The distance separating a circle's center and perimeter is its radius.
Let r be the radius of the circle. Then the area of the circle is written as,
A = πr² square units
The area of the circle is 89 square feet. Then the radius of the circle will be given as,
89 = πr²
Simplify the equation, then the radius is written as,
πr² = 89
r² = 28.34
r = 5.32 feet
if the circle's surface area is 89 square feet. The circle's radius will then be 5.32 feet.

An employee’s new salary is $16,275 after getting a 5% raise. What was the salary before the increase in pay?
Answer:
$15,500
Step-by-step explanation:
Let s represent the initial salary. That salary, plus a 5% raise, comes out to 1.05s = $16,275.
Solve for s by dividing both sides by 1.05:
s = $16,275 / 1.05 = $15,500.
The original salary was $15,500.
Final answer:
The original salary before a 5% raise resulting in a new salary of $16,275 was $15,500. We found this by dividing the new salary by 1.05.
Explanation:
The question asks us to determine an employee's original salary before a 5% raise. To solve this, we assume that the new salary ($16,275) is 105% of the original salary (100% + 5% raise). Therefore, we can set up the following equation: Original Salary × 1.05 = $16,275. Now, we want to find the Original Salary, so we divide $16,275 by 1.05.
Original Salary = $16,275 ÷ 1.05
When we divide $16,275 by 1.05, we get the Original Salary = $15,500.
Therefore, before the increase in pay, the employee's salary was $15,500.

consider the equation x^2=36. Which of the statements below are true? select all that apply
Answer:
See possible solutions below.
Step-by-step explanation:
The equation x^2 = 36 is a polynomial equation.
It can be solved by using a radical on both sides. The solution is x = +/- 6.
The equation has two solutions. x = -6, 6.
While this is a polynomial equation, it is specifically called a quadratic since the exponent is 2.
The equation x^2 = 36 has two real number solutions: x = 6 and x = -6. Statements that acknowledge both of these solutions as possible would be true.
Explanation:The equation in question is x^2 = 36. To solve this equation, one must realize that there are two real number solutions since squaring either a positive or negative number will result in a positive number. Taking the square root of both sides of the equation gives us two solutions: x = 6 and x = -6.
Therefore, any statement claiming that there is only one solution is incorrect. The true statements would acknowledge the existence of two solutions, one positive and one negative.

How many times the number of matches pete played is the number of matches jack played?
Answer:
Pete played 1.5 times the number of matches that Jack played.Step-by-step explanation:
Pete played 18 tennis matches in a week.
P = 18
Jack played 6 fewer matches than Pete.
J = P - 6
J = 18 - 6
J = 12
How many times the number of matches pete played is the number of matches jack played?
18 / 12 = 1.5
Pete played 1.5 times the number of matches that Jack played.
Answer:
Pete played 1.5 times the amount of matches Jack did.
Step-by-step explanation:
In order to find this, first find the number that Jack played. Since he played 6 fewer than Pete we can solve by subtracting 6 from Pete's number.
18 - 6 = 12
Now to find how many more times higher it is, divide the number Pete does by Jack's number. 18/12 = 1.5
