35
Step-by-step explanation:
Given that a fast food restaurant has the following options for toppings on their hamburgers: mustard, ketchup, mayo, onions, pickles, lettuce, and tomato.
A customer can choose from these 7 options 4 different options in 7C4 ways
This is because order does not matter here
So we use combinations here
Total no of ways a customer choose four different toppings from these
options=7C4
=35
Answer is 35
Sorry Im in 6th but i still have no idea......
How much part can sally paint in an hour ?
a ÷ 7 = a/7
And what about Steve ?
a ÷ 9 = a/9
Where, a is the total area of the room.
So, let the time taken by both of them to paint the room together be 't'
So,
t(a/7 + a/9) = a
t(9a/63 + 7a/63) = a
t(16a/63) = a
t = 63/16 ≈ 4 hr
