Find the area. Of the congruent figure. Use decimals in your answer if necessary.

Natali5045456 [20]

Answer:

200.5 km

Step-by-step explanation:

So we can break up this irregular polygon into many smaller easier to calculate kind of polygons like rectangle, or triangles.

We can break up this figure into 4 smaller ones:

3 rectangles:

a) a 23 by 5 size

b) a 12 by 4 size

c) a 4 by 5 size

1 triangle

a) 7 by 5 size

You find the area and add them up to get 200.5 km^2

Please help me, i need branliest answers. I hope u help me:)

Answer:

1.) 20,160 cookies, 2.) 37,600 Letters to students in a different country 3.) 252.36 Exact form, Approximate form: 252

Step-by-step explanation:

The first question is written in standard form like this:

Standard Form: 315 x 64 = 20,160

Algebraically/Logical: 315 Packages x 64 Cookies = 20,160 Cookies in All

Therefore, Kenneth bought 20,160 Cookies

The second question is written like this:

Standard Form: 940 x 40 = 37,600

Algebraically/Logical Reasoning: 940 students x 40 letters = 37,600 letters written to students in a different country.

Note: This question has a random P 240, That will be erased so that is why the equation is 940 x 40

The third question is written like this:

Standard Form: 36 x 7.01 = 252.36

Approximate form: 36 x 7 = 252

Algebraically/Logical Reasoning: The standard form would explain it all but if I was answering this question I would round 7.01 to the one's place because there is no way you would get a decimal when trying to solve an even amount of cloths. So there are 36 squares in one table cloth, times that by 7 which is equal to 252 approximently.

System w/Elimination<br>-2x-9y=-25<br><br>-4x-9y=-25

Lerok [7]

x=0 and y= $\frac{25}{9}$

Step-by-step explanation:

We need to solve the system by elimination and find values of x and y

$-2x-9y=-25\,\,\,(1)\\-4x-9y=-25\,\,\,(2)$

Subtract eq(1) and eq(2)

$-2x-9y=-25\,\,\,(1)\\-4x-9y=-25\,\,\,(2)\\+\,\,\,+\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,+\\---------\\2x=0\\x=0$

Now Multiply equation (1) by 2 and subtract with eq(2)

$-4x-18y=-50\\-4x-9y=-25\\+\,\,\,\,\,\,+\,\,\,\,\,\,\,\,\,\,\,\,\,\,+\\--------\\-9y=-25\\y=\frac{-25}{-9}\\y=\frac{25}{9}$

So, x=0 and y= $\frac{25}{9}$

The world’s largest round pizza was set in December 2012 by five Italian chefs. The diameter of this pizza was 131 feet. If this

Tems11 [23]

First find the area of the whole pizza.

The formula for area of a circle is Area = PI x r^2

The diameter is given as 131 feet, so r would be 131/2 = 65.5 feet.

I will use 3.14 for PI since the problem doesn't say what value to use.

Area = PI x 65.5^2

Area = 3.14 x 4290.25

Area = 13,471.39 square feet

Divide the total area by the number of pieces:

13,471.39 / 50 = 269.43 square feet

To find the length of the crust first find the circumference of the whole pizza:

Circumference = PI x diameter

Circumference = 3.14 x 131 = 411.34 feet

Now divide the total by the number of pieces:

411.34 / 50 = 8.23 feet

Each slice has an area of about 269.43 square feet and a crust length of 8.23 feet.
