6 0

Here is the answer of the given question above. In order to simplify the square root of 180, you need to search for a square number that is a factor of 180. It could be the following: 36 x 5, 4 x 45 or 9 x 20. Then once you are done with the factors, you can simply write it this way. √180 = √36×5. Then, this gives you 6√5. This is the exact form. The decimal form would be 13.41640786.

A piece of pipe is 303/4 inches long. If five pieces, each 41/3 inches long, are cut from the pipe, how many inches of pipe rema

galina1969 [7]

So, what is the total lenght of the pieces that wer cut off?

we multiply the lenght by the number:

4 $\frac{1}{3}$ *5=20+ $\frac{5}{3}$ =21 $\frac{2}{3}$

and we subtract this from the original pipe, that is

30 $\frac{3}{4}$ -21 $\frac{2}{3}$

we need to bring the two fractions to the same denominator (by multiplying the fraction art in the first by 3 and 4 the second):

30 $\frac{9}{12}$ -21 $\frac{8}{12}$ =9 $\frac{1}{12}$

so the correct answer is D!

marusya05 [52]

Answer:

The width is 88

Step-by-step explanation:

Perimeter of a rectangle: 2L + 2W

Step 1: Solve for W

374 = 2(99) + 2W

374 - 198 = 198 + 2W - 198

176 / 2 = 2W / 2

88 = W

Answer: The width is 88

Convert the polar representation of this complex number into its standard form z=4(cos150+isin150).

Katen [24]

Answer:

Step-by-step explanation:

Using the exact values

cos150° = - cos30° = - $\frac{\sqrt{3} }{2}$

sin150° = sin30° = $\frac{1}{2}$

Given

z = 4(cos150° + isin150° ) , substitute values

= 4(- $\frac{\sqrt{3} }{2}$ + $\frac{1}{2}$ i )

= - 2 $\sqrt{3}$ + 2i , that is

(- 2 $\sqrt{3}$ , 2 ) → B

Which is independent and which is dependent.

Arada [10]

Idk if you are talking about independent and dependent variables but if you are then the independent variable is the variable that is changed or controlled and the dependent variable is the variable being tested and measured in a scientific experiment. Hope this helps!!!❤️
