Answer:

4.) 6

5.) \frac{11}{15}  

Step-by-step explanation:

4.

PEMDAS

Parenthesis, Exponents, Multiplication, Division, Adition, Subtraction.

3 + 27 ÷ ( 4 + 5 )

Do the parenthesis first ( 4 + 5 )

3 + 27 ÷ 9

Do the division next ( 27 ÷ 9)

3 + 3

Now addition.....( 3 + 3)

6

__________________________________________________________

5.

\frac{1}{3} + \frac{2}{5}

In order to find the sum between these 2 fractions, we need to find a common denominator, and in this case, it can be 15...

\frac{1 * 5}{3 * 5} = \frac{5}{15}

\frac{2 * 3}{5 * 3} = \frac{6}{15}

Now that we have a common denominator, we can add them up...

\frac{5}{15} + \frac{6}{15} =\frac{11}{15} \\\\\frac{11}{15}

\frac{11}{15}  is ur answer.

Hope this helped!

Have a supercalifragilisticexpialidocious day!

Answer:

3 plus 27 divided by (4 plus 5) = 6

Find the sum 1/3 plus 2/5 = 11/15

Step-by-step explanation:

Find the sum 1/3 plus 2/5

Step 1

Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term.

So, we multiply 1 by 5, and get 5, then we multiply 3 by 5 and get 15.

1/3 times 5

Now for the second term. You multiply 2 by 3, and get 6, then multiply 3 by 5 and get 15.

2/5 times 3

We now have a new problem, that looks like this:

5

15

+  

6

15

Step 2

Since our denominators match, we can add the numerators.

5 + 6 = 11

Answer:

11 /15

Step 3

Now, do we need to simplify this fraction?

1 /3 +  2 /5= 11 /15

A ventilation fan is installed in a vertical position. As the fan rotates, the distance, in inches, between the tip of a fan bla
V125BC [204]

Answer:

The number of times the fan blade revolves each minute is 1,000 times

Step-by-step explanation:

The given function, y, that gives the distance between the tip of (one of the fan)  blade(s) and the ceiling is given as follows;

y = 6·cos(2,000·pi·x) + 11

Where;

x = The time, in minutes, at which the distance is measured

The general form of the cosine function is y = a·cos(b·x - c) + d

Therefore, by comparing with the given function, we have;

b = 2,000·pi

a = 6

c/b = The horizontal shift or phase shift

The period, p, (which is the time to complete one revolution of the fan blade) of the function is given as follows;

p = 2·pi/b

Therefore;

p = 2·pi/(2,000·pi) = 1/1,000 = 0.001 minutes/revolution

The number of revolution the fan completes per minute, which is the rpm is given as follows;

rpm = 1/p = 1/(0.001) ×1/minutes/revolution) = 1,000 revolutions/minute

Therefore;

The fan blade revolves 1,000 times each minute.
