Lengths of corresponding sides of similar polygons are in proportion.
That means that 2 is to 3 as 7 is to x where x is the length of the side of the other
triangle.
2/3= 7/x
2x = 21
x = 21/2 = 10 1/2
Answer: b) 10 1/2
Cole's error was that he did not round to the nearest ten thousand, he was supposed to write 20,000.
12.5 - 5.3 = 7.2 gallons
7.2 gallons x $1.30 = $9.36
$9.36 is your answer
Answer:
3.2
Step-by-step explanation:
Given the coordinates
X(4, -3)
Y(2, 1.5)
A(3, 3)
Z(4,-1)
We are to find the distance from point A to XZ
First let us get the coordinate XZ
According to vector notation XZ = Z-X
XZ = (4,-1)-(4,-3)
XZ = [(4-4),-1-(-3)]
XZ = (0, 2)
Next is to find the distance from A(3, 3) to XZ(0,2) using the formula for calculating the distance between two points.
D = √(x2-x1)²+(y2-y1)²
x1 = 3, y1 = 3, x2 = 0, y2 = 2
D = √(0-3)²+(2-3)²
D = √9+1
D = √10
D = 3.16
Hence the distance from point A to XZ to nearest tenth is 3.2
