Part A: 14 + 14 = y or 14•2 = y
Part B: (n•2) - 2 = a
Not 100% sure that this is correct but, hope this helps! :) If you have any questions than ask me.
Answer:
23/50
Step-by-step explanation:
27 + 23 = 50 (Implying that 50 is the total amount of tickets).
23 of them were sold to adults, so basically 23/50.
Remember a ratio can be written in 3 forms, so it can be either of these:
23:50
23/50
23 to 50

The Webster family is planning a barbecue for one hundred people. The Webster family needs one plastic plate for each person at the barbecue. The Stop and Shop store and Market Place Store both sell plastic plates in packages of fifteen for five dollars and ninety-nine cents per package. How many packages of plastic plates does the Webster family need to buy? What is the cost of plates for the barbecue?
Answer:
-The Webster family needs to buy 7 packages.
-The cost of the plates is $41.93.
Step-by-step explanation:
To calculate amount of packages that the Webster family need to buy, you have to divide the amount of people by the number of plates in each package:
100/15= 6.66
According to this, as they will need more than 6 packages, the Webster family needs to buy 7 packages to have one plastic plate for each person at the barbecue.
Then, the cost of the plates for the barbecue would be calculated by multiplying the price of each package for the number of packages needed:
$5.99*7= $41.93
The cost of the plates is $41.93.
Answer:
i am so sorry i dont get the question
Step-by-step explanation:
The formula for the distance from a point (x, y, z) to the plane ax +by +cz +d = 0 is this:
.. distance = |ax +by +cz +d|/√(a^2 +b^2 +c^2)
For your point and plane, that is
.. distance = |-8 -2*7 -4*6 -8|/√(1^2 +2^2 +4^2)
.. = 54/√21
.. = (18/7)√21
