<em>48 ft</em>

  • Step-by-step explanation:

<em>A  = 144ft² = l²</em>

<em>l = √144</em>

<em>l = 12 ft</em>

<em>P = 4l</em>

<em>= 4×12ft</em>

Which of the following describes the decimal .3? Repeating decimal Terminating decimal Circulating decimals Repeating factor? Th
drek231 [11]

Answer:

Repeating decimal

Step-by-step explanation:

The bar over any number to the right of a decimal point denotes that the number is recurring. Meaning that if the bar (line) is over the number 3 in 0.3, the number 3 is being repeated infinitely. (0.333333333333333333....)

These types of decimals are known as repeating or recurring decimals.

Hope this helps!

The lengths of the sides of a triangle are 3, 3, and the square root 3. Can the triangle be a right triangle?
Readme [11.4K]
First find the decimal equivalent of square root 3: SQRT(3) = 1.732 ( roughly)
 
If the base and height were each 3, then the hypotenuse would need to be:

3^2 + 3^2 = C^2
9 + 9 = C^2
18 = C^2
C = SQRT(18) = 4.24

This is larger than sqrt(3), so this cannot be a right triangle.


If one leg was 3 and the other leg was sqrt(3) then the hypotenuse would be:
3^2 + 1.73^2 = C^2
9 + 3 = C^2
12 = C^2
C = SQRT(12) = 3.46

This is larger than 3, this cannot be a right triangle.

The answer is b) no.

Minchanka [31]

Answer:

45 dogs

Step-by-step explanation:

so she has $550 and she did 20 cats and it costs $5 per cat and 5 x 20 is $100 and $550 - $100 = 450 and 450 divided by 10 ( because it's $10 per dog) is 45.
