let's firstly convert the mixed fraction to improper fraction, and then divide it by 4 to see what our quotient is.

Answer: a is the # of elements in A but NOT B, that is A ONLY
b is the # of elements in B but NOT A, that is B only
N is the # of elements in the INTERSECTION of A and B
a + N = 99
b + N = 25
a + b + N = 123
Subtracting the first two equations: a - b = 74
Subtracting the last two equations: -a = -98
a = 98
So then a - b = 74 and a = 98
98 - b = 74
-b = -24
b = 24
a = 98, b = 24 and a + b + N = 123
98 + 24 + N = 123
122 + N = 123
N = 1
98 are in A only
24 are in B only , which is the answer to the question
1 is in both A and B
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Incorrect answers = 100-77=23
Percentage of 23 out of 100 is (23/100)*100 = 23%
Answer:
2500000000
Step-by-step explanation:
→ Multiply 1 by 25000
1 × 25000 = 25000
→ Convert into metres
2500000
→ Convert into centimetres
2500000000
Hi! I will try my best to answer your question, the wording provided is unclear.
If the 10% of the original cost of something is $1.50, then the total cost is $15.00.
Assuming this is the discounted price, which would be 90% of the original cost, the original cost would be $16.67.
