Answers

The correct answers are:
$47.50;
$24.25;
$5.75;
$123.03;
$18;
$59;
Home by $7.50; and
separate rentals.

Explanation:
For the first question:
Your family purchases 2 adult tickets at $8 each; 2*8=16. You then purchase 1 10-18 ticket for $7.25 and 1 under 10 ticket for $4.25. You then purchase $20 in soda and popcorn. This gives us a total of:

16+7.25+4.25+20=47.50.

For the second question:
You purchase your ticket for 7.25 and a ticket for each of your siblings at 4.25, which is 2*4.25=8.50. You then purchase $10 in soda and popcorn. This gives us a total of:

7.25+8.50+10=25.75.

The change will be:
50-25.75=24.25.

For the third question:
5 tickets at $16.85 each would be 5*16.85=84.25.

This gives us
90-84.25=5.75 in change.

For the fourth question:
7 tickets at $13.79 each will cost 7*13.79=96.53.

The handling for all 7 tickets, at $2.50 each, will be 7*2.50=17.50

These together with the shipping charge will be
96.53+17.50+9=$123.03.

For the fifth question:
The book of 8 tickets, which cost $5.25 each, will be 8*5.25=$42.

This will give us
60-42=$18 in change.

For the sixth question:
He has buy one get one free tickets; this means he will buy 3 tickets and get 3 free for the first 6 tickets. He will then need to buy the 7th ticket; this means he will pay for 4 tickets:
4*10.25=$41.

Out of $100, he will have
100-41=$59 in change.

For the seventh question:
The tickets at Theatre Y cost 8.25*2=16.50. Two drink/popcorn combos at the theatre will cost 4.50*2=9. Together, this is 16.50+9=25.50.

The cost of the dvd rental (4.50), soda (1.50) and popcorn (2.00) at home is 4.50+1.50+2=8. This makes staying at home the cheaper option; it is
25.50-8=$17.50 cheaper.

For the eighth question:
4 separate rentals will cost 4*3.99=$15.96. This is cheaper than $20.

What is the perimeter of rectangle ABCD on the coordinate plane? coordinate grid

Answers

Drat it all I am so bad at reading. Sorry about that it is my fault :O

well the formula for a perimeter of a triangle is 2(lxw) so the length here is 10 i think (just count the cubes on the bottom) then with that number you multiply that by the width (side) then multiply by 2. i counted ten on the length and 5 on the width (im not sure if thats how any because its hard to cound on a tiny grid on a computer hehe), so i multiplied 10 x 5 and got 50, then multiply by 2, i got 100. im not sure, but ill double check :)

allie is making 8 dozen chocolate chip muffins and the recipe she is using calls for 16 ounce of chocolate chips for 3 dozen how many ounces does she need for her new amount

Answers

First off start with a ratio by which the recipe is smaller than the required amount. $(8)/(3) =2.67$
Then multiply 16 ounces by that ratio and voila.

The answer is: she has to buy 43 ounces

8 divided by 3 is 2.67. that times 16 is 42.67 , so a little less than 43 oz will be needed.

Which list of ordered pairs represents solutions to x + y = 2 ? (-4, 6), (0, 2), (4, 2) (-4, -6), (0, 2), (4, 2) (-4, 6), (0, 2), (4, -2)

Answers

The coordinates simply have to be plugged into the equation and determine whether the result is 2.
-4 + 6 =  2
0 + 2 = 2
4 + 2 =  6
-4 + -6 = -10
0 + 2 =  2
4 + 2 = 6
-4 + 6 = 2
0 + 2 = 2
4 + -2 = 2

The solutions (without repeating pairs) are:
(-4, 6), (0, 2), (4, -2)

Answer:

C: (-4, 6), (0, 2), (4, -2)
