Answer:

305.12 square inches

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The area of the window is equal to the area of a rectangle, plus the area of two quarter circles plus the area of the smaller square between the two upper corners

Find the area of rectangle

$A=(12)(26-4)=264\ in^2$

Find the area of the two quarter circle

$A=2[\frac{1}{4}(3.14)(4^2)]$

$A=25.12\ in^2$

Find the area of the smaller square between the two upper corners

$A=(12-8)(4)=4^2=16\ in^2$

The total area is equal to

$A=264+25.12+16=305.12\ in^2$

The equation of a circle in general form is x2+y2+18x−36y+369=0

swat32

You have to complete the square of (x²+18x+?) as well as for (y²-36y+?)

You will find: (x+9)² + (y-18)² = 36

& this is the standard equation requested

Keiko, Dale, and Tony sent a total of 95 text messages during the weekend. Dale sent 7 fewer messages than Kelko. Tony sent 4 ti

Answer:

Keiko sent 17 messages, Dale sent 10 messages, and Tony sent 68 messages

Step-by-step explanation:

Let x represent the number of messages that Keiko sent.

Since Dale sent 7 less than Keiko, his number can be represented by x - 7

Since Tony sent 4 times as many as Keiko, his number can be represented by 4x

Using these variables, create an equation:

(x) + (x - 7) + (4x) = 95

Add like terms and solve for x:

6x - 7 = 95

6x = 102

x = 17

So, Keiko sent 17 messages.

Subtract 7 from this to find how many Dale sent:

17 - 7

= 10

Multiply it by 4 to find how many Tony sent:

17(4)

= 68

So, Keiko sent 17 messages, Dale sent 10 messages, and Tony sent 68 messages
