For equations that model direct variation, they are of the form y = kx, where k is the constant of proportionality.
So, for there to be a constant of proportionality of 1/2, the equation should be y = 1/2 x.
This is the same as y = 3/6 x (since 1/2 = 3/6), so the answer is C.
Answer:
The cost per adult is $16.
Step-by-step explanation:
Given that:
Total number of children = 20+22 = 42 children
Total number of adults = 2 + 5 = 7 adults
Total cost for both groups = $490
Cost per child = $9.00
Cost of children ticket = 9.00*42 = $378
Cost of adult tickets = 490-378 = $112
This is the cost for 7 adult tickets.
Cost per ticket = 
= $16
Hence,
The cost per adult is $16.
4/105 In total there are 2+4+1+8=15 The probability of taking a blue is number of blue divided by number of total, so that would be 4/15. Since, it is not replaced, we can now say that there are 1 less marbles in the bag (since we took out a blue). Now probability of getting a green marble is:2/14=1/7
Answer:
20 inches by 28 inches
Step-by-step explanation:
The current size of the picture is 5 inches by 7 inches
If we want to enlarge the picture by a factor of 4, the perimeter will also increase by the factor of 4.
New dimension = 4(old dimensions)
= 4(5 inches by 7 inches)
= 20 inches by 28 inches
Hence, the size of the enlarged picture is 20 inches by 28 inches.
