Seven times seven equals forty nine
Answer:
31465 ways
Step-by-step explanation:
Given data
Let us apply the combination formula
nCr = n! / r! * (n - r)!
n= 31
r= 4
substitute
= 31!/4!(31-4)!
= 31!/4!(27)!
= 31*30*29*28*27!/ 4!(27)!
= 31*30*29*28/4!
=31*30*29*28/4*3*2*1
=755160/24
=31465 ways
Hence there are 31465 possible ways to rank it
Step-by-step explanation:
you need too look somewhere else
Use the formula I = Prt. Plug $2300 into P.
Plug 7.5% (decimal form is 0.075) into r.
Plug 10 into t.
Your simple interest after 10 years is $1725
Answer:
$77.44
Step-by-step explanation:
If the shoes cost $88 but you get a 20% discount, subtract 20% from 88: -->
$88-20% = $70.4
Then add 8% of 88 to 70.4 -->
8% of $88 = $7.04.
$70.4 + $7.04 = $77.44
Therefore the final price of the shoes are $77.44
