Angle a,b,c equals 222; because angle a and b already is 180; so there is a right angle in the top with a 48 degree next to it so add then up and its 138; now subtract 180 which is the total of the total angels with 138 and you get 42; now add that to 180 and you get your answer which is 222.

We need to solve the speed formula for d. To do so, let's start by moving the number of the left hand side:

$\frac{S}{356} = \sqrt{d}$

Square both sides to get rid of the square root:

$\frac{S^2}{126736} = d$

Now plug the known value of the speed to find the distance:

$d = \frac{140^2}{126736} = \frac{19600}{126736} \approx 0.15465$

So the closest answer is the last one: d=0.155km

There are 8 members on a board of directors. If they must form a subcommittee of 5 members, how many different subcommittee are

Assoli18 [71]

56 different sub-committees are possible

Step-by-step explanation:

When the selection has to be made without order, combinations are used.

The formula for combination is:

$C(n,r) = \frac{n!}{r!(n-r)!}$

Here,

Total members = n = 8

Members to be selected = r = 5

So,

$C(8,5) = \frac{8!}{5!(8-5)!}\\= \frac{8!}{5!}\\=56\ ways$

Hence,

56 different sub-committees are possible
