If I have a circle that is 12 in in diameter and it's cold and a half and then folded in half again what is the area of the resulting shape and what is how do I write out the equation

Answers

Answer:

A= πr^2/4

Step-by-step explanation:

Step one:

given data

diameter of circle= 12 in

the radius is r=d/2=6in

the area of the circle is

A=πr^2

A=3.142*6^2

A=3.142*36

A=113.1in^2

If the circle is folded in half, the area will be A/2= 113.1/2= 56.55in^2

In the corresponding shape is folded again the area is A/4= 28.3in^2

The expression for the last shape is

A= πr^2/4

Given

point (3,-7)

m = 5

Solution

y - y1 = m(x - x1)

y - (-7) = 5(x - 3)

y + 7 = 5x - 15

y = 5x - 15-7

y = 5x-22

Mira has breakfast at a restaurant. She leaves a 20\%20%20, percent tip of \$1.80$1.80dollar

Answers

Answer:

Price of Mira Breakfast = 9 $ before tip

Step-by-step explanation:

Let say Mira's breakfast Price = B $

Tip she left = 20 %

20 % Tip amount =  (20/100) B =  0.2B $

Tip Amount She left = $ 1.8

Equating Tip Amount

0.2B = 1.8

=> B = 9

Price of Mira Breakfast = 9 $ before tip

If 2 (3t - 10) + t = 40 + 4t, what is the value of 3t?

Answers

To start, simplify the equation using PEMDAS
parentheses first
6t-20+t=40+4t
Then, because there aren’t like terms, we can’t multiply/divide/add/subtract until we get the like terms together. So move all the t s to one side
6t+t-4t=20+40
Add like terms
3t=60

There’s 3t and it’s value!
60!

Hope this helped! If so, please make it brainliest!!

The value of 3t is given by the equation A = 75

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

2 ( 3t - 10 ) = 40 + 4t

On simplifying the equation , we get

6t - 60 = 40 + 4t

Subtracting 4t on both sides of the equation , we get

4t - 60 = 40

Adding 60 on both sides of the equation , we get

4t = 100

Divide by 4 on both sides of the equation , we get

t = 25

So , the value of 3t = 25 x 4

The value of 3t = 75

Hence , the equation , 3t = 75

Solve this algebraic expression:
5x-2(3x)

Answers

5x - 2(3x)

5x - 6x

-1x


Answer:

-x

Step-by-step explanation:

Simplifying

5x + 2 = 3x

Reorder the terms:

2 + 5x = 3x

Solving

2 + 5x = 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

2 + 5x + -3x = 3x + -3x

Combine like terms: 5x + -3x = 2x

2 + 2x = 3x + -3x

Combine like terms: 3x + -3x = 0

2 + 2x = 0

Add '-2' to each side of the equation.

2 + -2 + 2x = 0 + -2

Combine like terms: 2 + -2 = 0

0 + 2x = 0 + -2

2x = 0 + -2

Combine like terms: 0 + -2 = -2

2x = -2

Divide each side by '2'.

x = -1

Simplifying

x = -1

= -x
