ASHA 777 [7]

Answer:

The number of ways Tony and Maria can both be selected for the committee is 8 ways.

Step-by-step explanation:

i) Tony and Maria have to be on the committee together or not at all.

ii) Let us consider Tony and Maria as combined as one person.

 Therefore now we can say that the number of eligible people for the committee = 9 - 1 = 8.

iii) therefore the number of ways that both Tony and Maria can be selected for the committee are

 = 8C1   =  \hspace{0.2cm}\binom{8}{1} = \frac{8!}{1! (8-1)!}  = \frac{8!}{1!\times 7!}  = \frac{8}{1}  = \hspace{0.1cm}8 \hspace{0.1cm}ways

Please help me answer this step by step would be helpful
UNO [17]

Answer:

Step-by-step explanation:

The viniculum in a fraction represents subtraction with exponents.

Subtracting exponents gives us  3^12/3^8 * 3^2

Simplifying gives 3^12/3^10. Then, we can achieve 3^12 - 3^10.

This equals 3^2.

3^2 = 9.

So 9 is the answer of your question.

What would the length of segment BC have to be in order for line BC to be tangent to circle
Tju [1.3M]

Given data:

The first given length is AC=53.

The second given length is AB= 45.

The expression for the Pythagoras theorem is,

\begin{gathered} AB^2+BC^2=AC^2 \\ (45)^2+BC^2=(53)^2 \\ BC^2=784 \\ BC=28 \end{gathered}

Here, consider only positive sign of BC length as side cannot negative.

Thus, the BC length is 28.
