Solution: The correct option is option (B) 1.08(0.87y).
Explanation:
It is given that the original cost of cards is y. It is also given that cards was on sale of 13% and the tax in the country is 8%.
There is a sale of 13% it means the prices are 13% less.
13% of y =
The price of cards after discount is

The price after discount is 0.87y.
It is given that the tax in the country is 8%.
The amount of tax on the cards is calculated as shown below,

The price after discount is is calculated as shown below,

Therefore, the correct option is option (B) 1.08(0.87y).
Answer:
x=-4 and y=10
Step-by-step explanation:
Use the second equation to make y=x+6
sub y=x+6 into the first equation
-x-2*(x+6)=0
-x-2x-12=0
-3x-12=0
3x=-12
x=-4
Now sub x=-4 into the second equation
-(-4)+y=6
y=6+4
y=10
Answer:
Step-by-step explanation:
162, 188, 197, 201, 266
a. add all number: 1014/ 5 = 202.8
b. 266-162 = 104
c. for each number subtract the mean and square the result.
1664.64+219.04+33.64+3.24+3994.24
= 5914.8/5 = 591.48
d. square root of variance
= 24.32
e. i don't know this one because i need the number of people in the family
Answer:
e= 25.63
Step-by-step explanation:
The opposite sides of a rectangle will always be congruent. If they aren't, it's not a rectangle.
To find CD, you need to find what z is. This can be found using the given, the perimeter, and plugging that into the perimeter formula using the information given. You end up with 2(4z - 3) + 2(3z - 1) = 132. Solve for z and you find that z = 10.
CD is congruent to AB, which is 3z -1. Plug z in to get AB = 29. Since AB = CD, CD = 29.
