She buy 48 inches of ribbon to have the exact amount that she needs.

Given,

Area of the ribbon = 144 sq. inches

and, We know the formula for side of square is =[tex]\sqrt{Area of a square }[/tex]

Plug the value of area of square in above formula

Side of a Square = [tex]\sqrt{144}[/tex] = 12 inches

Now, we get the side of a square i.e., 12 inches

According to the question:

Sonya wants to sew ribbon along each side of a square pillow.

So, we need to find the perimeter of the square pillow.

and, Perimeter of a square is = 4 x side

=> Perimeter = 4 x 12 = 48 inches.

Therefore, She buy 48 inches of ribbon to have the exact amount that she needs.

Answer:

x = 2

Step-by-step explanation:

x + 3 + 1/2 x + 3 +x + 1 = 12  Combine like terms

21/2 x + 7 = 12   Subtract 7 from both sides of the equation

2 1/2 x = 5

The numerical length of GH = 20 units

FH is a line segment.

G is a point on the line segment.

Then G divides the line segment FH into two line segments FG and GH.

We are given the lengths of FH, FG and GH in terms of x.

That is,  FH=4x+8, FG=x and GH=5x

We need to find the numerical length of the line segment GH. We first need to find the x for this.

As G cuts the line segment FH into two parts, the length of the line segment FH is the sum of the lengths of the line segments FG and GH.

That is, FH = FG + GH

⇒ 4x+8 = x +5x

⇒ 4x+8 = 6x

⇒ 2x = 8

⇒ x = 4

So the numerical length of GH = 5x = 5 x 4 = 20 units

The value of of slope of is 1/4.

It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope of lines in a coordinate plane can aid in anticipating whether the lines are parallel, perpendicular, or none at all without actually using a compass.

Any two distinct places along the line can be used to determine the slope of any line. When two different places on a line are considered, the slope of a line formula compares the "vertical change" to the "horizontal change" in each case. The difference between the line's y and x coordinate changes is known as the slope of the line. Net changes in the y and x coordinates are as follows: y = y and x = x.

m = [tex]y_{2} - y_{1} /x_{2} x_{1}[/tex]

The total distance climbed by Kristen and her family is 16 meters.

It is given in the question that Kirsten and family climb down to 8 meters below ground level. Then they climb the opposite of 8 meters to return to ground level.

We have to find the total distance climbed by Kristen and her family.

We know that,

Total distance climbed by Kristen and her family = Distance climbed down the cave + distance climbed up the cave to reach ground level

Hence, we can write that,

Total distance climbed by Kristen and her family = 8+8 = 16 meters.

expression to be in form of h

To find on the interval: [9, 9 + h]

∵ Average rate of change of f(x) on interval (a,b) is

A = f(b) - f(a) / b - a

⇒ f(9) = 1 x 9 + 12 = 21

⇒ f(9 + h) = 9 +h + 12 = 21 + h

⇒ f(b) - f(a) = 21 + h - 21 = h

⇒ (b-a) = 9 + h - 9 = h

Answer:

y = mx + b

y = 1/4x + 2

Step-by-step explanation:

m(slope) = rise/run = 1/4

b(y intercept) = 2

     To prove this, we need to show that 2 is equal to x.

     Given:

2(x + 5) - 3x = 7x - 6

     Distribute:

2x + 10 - 3x = 7x - 6

     Combine like terms:

-1x + 10 = 7x - 6

     Add 1x to both sides of the equation:

10 = 8x - 6

     Add 6 to both sides of the equation:

16 = 8x

     Divide both sides of the equation by 8:

2 = x

Answer:

x=22

Step-by-step explanation:

Since a straight line is equal to 180 degrees,

(3x+3)+(5x+1) = 180

(3x+3)+(5x+1)-180=0

8x+4-180=0

8x-176=0

8x=176

x=176/8

x=22

Which also means that the first angle is (3(22)+3)=69 degrees

the second angle is (5(22)+1) = 111 degrees

111 + 69 = 180

Price of key ring = £1.6

Price of purse = £3.2

The unitary approach is a strategy for problem-solving that involves first identifying the value of a single unit, then multiplying that value to figure out the required value.

Given Data

Vicky makes 8 purses and 9 key rings to sell for charity.

Vicky wants to get a total of exactly £40

Suppose the price of key ring be v

and the price of purses be 2v

£40 = £8(2v) + £9(v)

40 = 16v + 9v

40 = 25v

v = [tex]\frac{40}{25}[/tex]

v = 1.6

The linear equation in point-slope form of a line with a slope of 23 and point (3,-2) is y = 23x - 71.

The slope intercept formula is expressed as;

y = mx + b

Where m is the slope and b is the y-intercept.

Given the data in the question;

Point: (3,-2)

First, use the the formula for the equation of line to determine the y-intercept 'b'.

y = mx + b

Plug in slope m = 23 and point (3,-2)

-2 = (23)3 + b

-2 = 69 + b

b = -2 - 69

b = -71

Now that we have both the slope m ( 23 ) and y-intercept b ( -71 ), plug these values into y = mx + b to find the linear equation.

y = mx + b

y = 23x + (-71)

y = 23x - 71

Therefore, the equation of the line is y = 23x - 71.
