Y=mx+b
m=slope
perpendicular lines have slopes that multiply to get -1
the slopes are
for
and
, the slope are
since their product is -1, the lines are perpendicular
Step-by-step explanation:
B) Surface Area
C) Volume
Answer:
2 1/4
Step-by-step explanation:
set 1.5/24=x/36
cross multiply to find x
Cost of the meal ordered by Mr. Rodriguez = $6.25
Cost of the meal ordered by Mrs. Rodriguez = $7.50
Cost of each pizza ordered by the two children = $4.99
Then
The cost of the 2 pizzas ordered by the 2 children = (2 * 4.99) dollars
= 9.98 dollars
So
The total cost of the orders = (6.25 + 7.50 + 9.98) dollars
= 23.73 dollars
Percentage of tip on the bill = 15%
Then
Amount of tip paid = (15/100) * 23.73 dollars
= 355.95/100 dollars
= 3.56 dollars
Percentage of tax paid on the bill = 7.25%
Amount of sales tax that was paid = (7.25/100) * 23.73 dollars
= 172.04/100 dollars
= 1.72 dollars
So
The total bill that was paid = (23.73 + 3.56 + 1.72) dollars
= 29.01 dollars
Pretty sure it's A. (X times .5 equals Y)
