Answer:
Choice A. $2,392 is the correct answer :)
Step-by-step explanation:
Elisa, e = 11mins
Prenav,p = 13mins
time to complete, t
1 = t( 1/11 + 1/13) = t (24/143)
t = 143/24 = 5.96min
Answer is A 5.96mins
Answer:
3/12
Step-by-step explanation:
Theres 12 possibilities and she has 3 numbers which means each number has a 1 out of 12 chance of winning the prize. Molly has three numbers so she has a probability of 3/12 to win a prize.
Answer:
Longest possible length for each of the shorter lengths of ribbon is 9 cm because greatest common factor for both 36 and 45 is 9.
Step-by-step explanation:
Alannah has two ribbons one length is 36cm and other is 45cm.
It asked to find shorter length of ribbons that each cut into equal pieces with out no ribbon left over.
So, let's find greatest common factor for both 36 and 45.
Let's prime factor each number
36= 2*2*3*3
45= 3*3*5
So, GCF is product of common factors for both numbers.
GCF= 3*3 =9
So, longest possible length for each of the shorter lengths of ribbon is 9 cm.
