Answer:

37.6 in

48.2 yd

Step-by-step explanation:

The are of a circle is given as :

Area = pi(d²) /4

Area = 1110.4in²

1110.4 = 3. 14 * d² / 4

1110.4 * 4 = 3.14 * d²

4441.6 = 3.14d²

d² = 4441.6 /3.14

d² = 1413.8051

d = 37.600

d = 37.6

8.)

Area, A = 1824.7yd²

1824.7 = 3. 14 * d² / 4

1824.7 * 4 = 3.14d²

7298.8 = 3.14d²

d² = 7298.8 / 3.14

d² = 2323.2801

d = sqrt(2323.2801)

d = 48.200

Hence, diameter = 48.2 yd

Answer:

Step-by-step explanation:

ahh this is a really tough one  :D  Does this happen to be an AP math class,  Pineapple    .. you are in advanced math :O.... good for you  :)

sooo what can we set equal

note the lines  have the same lenght, therefore the arc length will also be the same,  then they give us the other two lengths to make the entire circle , yay

so then just set all the arc lengths equal to 360 °

(3x+ 30) + (3x + 30 ) + 2x + 4x = 360  ( put like terms together )

12x +  60 = 360    ( subtract 60 from both sides )

12x = 300   ( divide both side by 12 )

x = 25

nice we now know X  :)

Answer: The answer is because 12 is how many bows the work made and 0.5 is 5 feet of the ribbon left.

Answer:

X > 40

Step-by-step explanation:

Given that:

Let number of coins in her collection is more Than 40

To represent the number of coins in Melissa's collection as an inequality :

Let total number of items in her collection = X

Coins in her collection > 40

Hence, coins in her collection can be represented as :

X > 40

Answer:

f(x)=x+2

Step-by-step explanation:

Pick any two points from the question and plug them into the equation y2-y1/x2-x1. In this case, I picked (0,2) and (1,3). Therefore, the equation will be   3-2/1-0. Simplify this to get 1/1 which is equal to 1. Therefore, the slope is equal to 1. Then pick a point and plug it into the point  slope form equation which is y-y1=m(x-x1) where m is the slope. In this case, I picked (0,2). Therefore, the equation will be y-2=(x-0). Simplify this to get y-2=x. You want to isolate y so you have to add 2 to both sides. This will make the equation y=x+2 which is the answer. Therefore, the answer is y=x+2 or f(x)=x+2.

Answer:

   1/6

Step-by-step explanation:

The gradient of the line segment is the same as slope

m = (y2-y1)/(x2-x1)

   = ( -4 - -5)/( 2 - -4)

   = (-4+5)/( 2 +4)

   1/6

Answer:

Step-by-step explanation:

Gradient = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]

               [tex]=\frac{-4-[-5]}{2-[-4]}\\\\=\frac{-4+5}{2+4}\\\\=\frac{1}{6}[/tex]

Answer:

17 will represent the batches of purple paint he wanted to make. It also represents the number of cup needed for each blue and red paint.

Step-by-step explanation:

Hence, [tex]17[/tex] represents the number of cups required for the blue and red paint and it also represent the batches of purple paint he wants to do.

What is the equation?

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here given that,

To make the perfect purple hue, the artist used cup of blue paint per batch and cup of red paint per batch. He wanted to make [tex]17[/tex] batches of purple paint.

Hence, [tex]17[/tex] represents the number of cups required for the blue and red paint and it also represent the batches of purple paint he wants to do.

Answer: D (3,4) trust and believe

brainlyst pls I think I spelt is wrong

Step-by-step explanation:

When a line or shape or point is rotated, it must be rotated around a point.

The image of the point is D. (3,4)

The point is given as:

[tex]\mathbf{(x,y) = (-3,-4)}[/tex]

A 180-degree rotation across the origin is represented as:

[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]

Substitute values for the coordinates of the point (x,y)

[tex]\mathbf{(-3,-4) \to (-(-3),-(-4))}[/tex]

Simplify

[tex]\mathbf{(-3,-4) \to (3,4)}[/tex]

Hence, the image of the point is D. (3,4)

Answer:

11.5 cm

Step-by-step explanation:

The dimensions of a right angled triangle can be determined using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = hypotenuse

a² + 8² = 14²

a² + 64 = 196

a² = 196 - 64

a² = 132

find the square root of 132

a = 11.5 cm
