The ice cream shop offers 31 flavors. you order a double scoop cone how many different ways can the clerk put the ice cream on t

Lynna [10]

Answer:

465

Step-by-step explanation:

Since we are looking for the the number of combinations to have 2 different flavors in the ice cream, we can use the formula for combination.

$_{n}C_{k}=\dfrac{n!}{k!(n-k)!}$

Our variables are:

n = 31

k = 2

$_{31}C_{2}=\dfrac{31!}{2!(31-2)!}$

$_{31}C_{2}=\dfrac{31!}{2!29!}$

$_{31}C_{2}=465$

The number of possible combinations of having 2 different flavors out of 31 different flavors is 465.

Find the angle of XZY

qaws [65]

Answer:

Step-by-step explanation:

<h3>to understand the solving steps</h3><h3>you need to know about</h3>

trigonometry i.g sin(x)=opp/hypo
PEMDAS

<h3>given:</h3>

opp:6
hypo:15

xyz angle

<h3>let's solve:</h3>

$let \: xyz \: angle \: be \: \alpha$

$according \: to \: the \: question$

$\sin( \alpha ) = \frac{xy}{zy}$

$\sin( \alpha ) = \frac{6}{15}$

$\alpha = asin( \frac{6}{15} )$

$\alpha = {23.6}^{o}$

therefore

<h3>xyz angle=23.6°</h3>
