Compare square root of one hundred eighty and one hundred two eighths using &lt;, &gt;, or =.
olga2289 [7]

Converting the mixed number to a decimal, the correct comparison of the numbers is given as follows:

\sqrt{180} > \sqrt{100 \frac{2}{8}}

<h3>What is a mixed number?</h3>

A mixed number is represented by an integer part and a fractional part, as follows:

a b/c.

In which:

  • a is the integer part.
  • b/c is the fractional part.

In this problem, the numbers are given as follows:

\sqrt{180}, \sqrt{100 \frac{2}{8}}

The mixed number is:

100 and 2/8 = 100 + 0.25 = 100.25.

The square root is an increasing function, hence the higher the input, the higher the square root, as 180 > 100 the comparison is:

\sqrt{180} > \sqrt{100 \frac{2}{8}}

Kevin wants to cover a rectangular floor that is 15 feet by
igor_vitrenko [27]

Answer: 50 square yards

Step-by-step explanation:

From the question, we are informed that Kevin wants to cover a rectangular floor that is 15 feet by 30 feet with carpeting.

The first thing to do is to convert the measurement that were given to yards. We should note that 1 yard = 3 feet

15 feet = 15/3 = 5 yards

30 feet = 30/3 = 10 yards

Area = 5 × 10 = 50 square yards

What is the simplified form of (4j2+6)+(2j2-3)
Galina-37 [17]

Answer: 6j^2+3

Step-by-step explanation:

In order to solve this exercise it is important to remember the multiplication of signs. Notice that:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-

In this case you have the following expression given in the exercise:

(4j^2+6)+(2j^2-3)

Where the variable is "j".

When you multiply signs, you get:

=4j^2+6+2j^2-3

Now you need to identify that like terms and then you need to add them (or combine them). So, applying this procedure you get that the simplified form of the expression is  the shown below:

=6j^2+3

As you can observe, you get a 2nd degree binomial.

6cos x-6sin x=3.sqrt6
Yakvenalex [24]
Divide by 6
cos x - sin x = \frac{\sqrt{6}}{2}

Square both sides
cos^2 x -2 sin x cos x + sin^2 x = \frac{3}{2}

Simplify Left side using Trig identities: (Pythagorean, Double Angle)
1 - sin (2x) = \frac{3}{2}

Solve for x:
sin (2x) = -\frac{1}{2}  \\  \\ 2x = \frac{7 \pi}{6}, \frac{11 \pi}{6} \\  \\ x = \frac{7 \pi}{12}, \frac{11 \pi}{12}
