Answer:
$30.41
Step-by-step explanation:
To find the tax she paid take the total amount times the rate of tax
24.20x.05=1.21
Then add the tax to the amount she paid before tax was added and the tip
$1.21+$24.20+$5=$30.41
So she spent $30.41 at the restaurant
To find the length of the side of the square, we just need to find the distance between the two endpoints. This problem can quickly be solved by using the
distance formula, but for those who are not familiar with it, we can simply solve it by analyzing a triangle.
Take a look at the diagram below. We are interested in x. To find this we have created a right triangle. The horizontal component is just the distance between the x coordinates of the two points while the vertical component is the distance between the y coordinates.
The horizontal component is 9 and the vertical component is 5. We can now get x by using the
pythagorean theorem:


which is approximately equal to 10.30 units.
ANSWER: The length of the side of the square measures 10.30 units.
A side is 4t so A=400=16t^2 by definition. Thus t=5 which produces an area of 400 since [4 (5)]^2=20×20=400.
The answer is 0.60 because the sum of the shaded angles equals 145°, divided by 360° equals 0.60
Answer:
Step-by-step explanation:
set up the equation
1.48=(x-405)/97
x=548.56=549
