Step-by-step explanation:
Calculate. Good luck in scramble with friends.
4 squared = 4^2 = 16. This can be approx. by rounding it up to 20 (which is the nearest hundredths place).
We need to find the number of possible combinations<span> of </span>r<span> objects from a </span>set<span> of </span>n<span> objects. </span>
Jean has 5 different colors which means that n=5 and 2 colors are used to make a sign, which means r=2.
The number of combinations can be calculated with the formula:
C=n!/((n-r)!r!)
C=5!/(5-2)!*2!
C=5*4*3!/3!*2*1
C=20/2=10
The possible combinations are:
1.red blue
2.red green
3.red orange
4.red purple
5. blue green
6. blue orange
7. blue purple
8. green orange
9. green purple
10. orange purple
Answer: There are £61.50 in 992 rubles
Step-by-step explanation:
£31 = 500 rubles
£x = 992 rubles
To get c, what we do is simply cross multiply
£x * 500 rubles = £31 * 992 rubles
£x = (£31 * 992 rubles)/500 rubles
£x = £61.504
which is £61.50 to two decimal places
