Which explanation best describes how to solve this problem? Marcia covered her kitchen floor with twice as much tile as her bath

erica [24]

Answer:

54 ft^2

Step-by-step explanation:

Bathroom area is 15 ft^2

The kitchen is twice the bathroom

2*15 = 30 ft^2

Kitchen: 30 ft^2

Front door: 9ft^2

The total is all the areas added together

Total = bathroom + kitchen + front door

= 15 ft^2 + 30 ft^2 + 9 ft^2

= 54 ft^2

Wally is rebuilding his fence. Each section of the fence will have 12 vertical boards that are each eight inches wide. He’s goin

Leokris [45]

Answer:

Part A)

Each diagonal is about 9.43 feet.

Part B)

In total, Wally needs about 736.02 feet of wood.

Step-by-step explanation:

Part A)

Since each vertical board has a width of 8 inches, for one section with 12 vertical boards, the total width will be 8(12) = 96 inches.

96 inches is the same as 96/12 = 8 feet.

We are also given that the horizontal pieces will be 5 feet apart.

To find the diagonal, we can use the Pythagorean Theorem. The 8 is the base and 5 is the height. Therefore:

$\displaystyle d^2=8^2+5^2$

Compute:

$d^2=89$

Taking the square root, we acquire:

$\displaystyle d=\sqrt{89}\approx9.43 \text{ feet}$

So, each diagonal is about 9.43 feet.

Part B)

For each section, we have two horizontal pieces (each 8 feet) and one diagonal piece (each √89 feet).

Therefore, for one section, we will need a total of:

$\displaystyle L=8+8+\sqrt{89}=16+\sqrt{89}$

Then for 30 sections, we will need:

$T=30(16+\sqrt{89})$

Approximate:

$T\approx 763. 02$

Wally will need about 736.02 feet of wood in total.

Find the perimeter of the triangle shown using the Associative proprety. 4 1/2 in 5 1/2in 6 in

torisob [31]

So assumn that the measures given are the legnths of the sides
perimiter=side1+side2+side3
so
side1=4 and 1/2
side2=5 and 1/2
side3=6
subsitute
p=(4+1/2)+(5+1/2)+(6)
associative prpoerty says (a+b)+c=a+(b+c) (it deals with addiont with parenthasees)
p=4+1/2+5+1/2+6
p=4+5+1/2+1/2+6
p=9+1+6
p=10+6
p=16 inches
