There are 5040 ways he can play his cards if he is required to play one card at a time.

Step-by-step explanation:

Given :Marcos has been dealt seven different cards.

To Find :How many different ways can he play his cards if he is required to play one card at a time?

Solution:

No. of cards = 7

He is required to play one card at a time

So, For first draw he has 7 choices

For second draw he will have 6 choices and so on

On seventh draw all cards will be drawn .

So, No. of ways he can play his cards if he is required to play one card at a time=

Hence There are 5040 ways he can play his cards if he is required to play one card at a time.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

6e14 is the answer.
