10 out of every 65 students order pizza for lunch. There are 416 students at her school. How many students will eat pizza at her
Studentka2010 [4]

Answer:

64

Step-by-step explanation:

First, you divide 416 by 65. This gets you 6.4. But it's not 1 in 65 eating pizza, it's 10 out of 65, so then you multiply 6.4 by 10, getting 64.

What is the exact value of tan 30° ? enter your answer, as a simplified fraction, in the box?
attashe74 [19]

In this question , we have to find the value of tan 30  and we need to write the answer in simplified form .

tan x = \frac{sin x}{ cos x}

Substituting the values of sin (30) and cos(30, we will get

tan (30) = \frac{1/2}{ \sqrt{3} /2}

Multiplying both numerator and denominator by 2, we will get

tan(30 )  = \frac{1}{ \sqrt3}

TO simplify it, we need to multiply both numerator and denominator by square root 3.

tan(30) = \frac{ \sqrt 3}{ \sqrt3 * \sqrt 3} = \frac{ \sqrt 3}{3}
