X value is -1. y value is 21
Start off by finding 18% of 13.90.
18%=18/100=0.18
0.18(13.9)=2.5
An 18% tip would be $2.50.
Now, to find out if Lana has enough money, add $2.50 to $13.90 to find out the total amount she would leave. You get $16.40. Since $16.40>$15, the answer is no because the total cost including the 18% tip is greater than $15.

Answer:
1260 cm^2
Step-by-step explanation:
To find the area of the rectangle we need its base and its height and calculate the product A = (base)(height).
Here the height of the triangle is found using the Pythagorean Theorem:
37^2 = |AB|^2 + 12^2, or |AB|^2 = 1369 - 144, or 1225.
Taking the square root of both sides, we get |AB| = √1225 = 35 cm = height of rectangle.
Since BC:CD = 1:2, and since |BC| = 12 cm, |BD| is 12 cm + 24 cm = 36 cm.
Thus the length of the rectangle is 36 cm.
The area of the rectangle ABDE is (36 cm)(35 cm) = 1260 cm^2
Answer:
Marry's seat is units far from Betty's seat
Step-by-step explanation:
We are given that Class of Math is mapped on a coordinate grid and center point of the hall is at origin.
Coordinates of Mary's seat are (2,2) and Coordinates of Betty's seat are (6,7). We have to find how far is Mary's seat to Betty's seat. In order words, we have to find the distance between Marry's seat and Betty's seat.
Remember that whenever the coordinates of two points are given, the distance between them is calculated using the distance formula. The distance between two points and is given by distance formula as:
Here, the points with subscript 1 are initial points (2,2) and the point with subscript 2 are final points (6,7). Using these values in the formula, we get:
This means, Marry's seats is units far from Betty's seat
