Answer:
5=12
3=? then Criss cross it and you will get 12*3 divided by 5 then you get 7.2
so the answer will be 7 days
10 kilometers because 10 kilometers = 6.21371192 miles or
6.21 the formula to convert miles to kilometers5 mi*63360 in 1 mi*2.54 cm 1 in*1 km 100000…
A scale that multiplies the quantity you can right it as a proportion or fraction
Remember that
the formula to calculate the combination is equal to
nCr=n!/[r!(n-r)!]
in this problem
we have
n=4
r=3
substitute the given values
4C3=4!/[3!(4-3)!]
4C3=4!/[3!(1)!]
4C3=4*3!/3!
4C3=12
the answer is 12
For 2 scoops
we have
n=4
r=2
substitute
4C2=4!/{2!(4-2)!]
4C2=(4*3*2*1)/4
4C2=6
the answer is 6
