Answer:
B
Step-by-step explanation:
The maximum amount Eric can spend on magazines is $25 less the cost of lunch, $15.
The appropriate inequality sign would be less than since he cannot spend more than $25.
Also, the amount he can spend on magazines would be what is left after paying for lunch.
So the correct inequality is 4m - 15 < 25
There are 4! = 24 poosible permutations of the four letters. Let the letters be A, B, C and D. Two permutations will have only letter A in the correct envelope, two more permutations will have only letter B in the correct envelope, two more will have only letter C in the correct envelope and two more will have only letter D in the correct envelope. Therefore 8 out of the 24 possible permutations will have only one letter with the correct address. The required probability is 8/24 = 1/3.
Answer is 50cm, to get the diameter you divide the circumference by pi.
Answer:
y = 
Step-by-step explanation:
Given y is inversely proportional to x² then the equation relating them is
y = 
← k is the constant of proportion
To find k use an ordered pair from the table
Using x = 3 when y = 1 , then
1 = 
= 
( multiply both sides by 9 )
9 = k
y = ← equation of proportion
