Step-by-step explanation:
Given
Triangles ABC and DEF
Required
Determine the scale of dilation
First, we pick a side on ABC

Pick a corresponding side on DEF

The scale factor is then calculated as:


i.e. ABC was dilated by 1/2
Answer:
D = 9.4868
Step-by-step explanation:
The expression is the following
D = √((x2-x1)^2+(y2-y1)^2)
Where
(x1,y1) = (4,6)
(x2,y2) = (7,-3)
D = √((7-4)^2+(-3-6)^2)
D = √((3)^2+(-9)^2)
D = √(9+81)
D = √(90)
D = 9.4868
Answer:
Step-by-step explanation:
A proportional
Given:
Cost of a game = $39.99
Shipping charge = $4.85
Let,
number of video games be "n"
Now,
total cost = (cost of each game * total no. of games) + shipping charge
= $39.99n + $4.85
So, you use the above equation to find the total cost of video games.
Answer:
$48
Step-by-step explanation:
The dress's price is $40. That is 100% of the dress's price.
Since tax is 20%, you need to add 20% to the 100%.
100% + 20% = 120%
The total cost including tax will be 120% of the cost of the dress.
To find a percent of a number, multiply the percent by the number.
120% of $40 =
= 120% * $40
= 1.2 * $40
= $48
