Answer:

Step-by-step explanation: you divide 11 by 5 because you know the length for the same side on both of those triangles therefore you divide the number for the larger figure by thesmaller one and you get you get your scale factor (the number you divide or multiply by to shrink ir stretch a figure to equal the size a similar figure). Now knowing what you scale factor is you can multiply 6 times 2.2 to get 13.2. Also you multiply 6 and 2.2 because on both triangles if you were to rotate them 6 and x are the same side of both triangles. I hope I helped.

Find the lengths of two segments whose sum is 45 and whose ratio is 2:3
ohaa [14]
Let the two segments be x and y
x+y=45...1
X/y = 2/3...2
From1, y=45-x
Sub this into 2
x/(45-x)=2/3
3x=90-2X
5x=90
x=18
y=45-18=27

The vertices of a rectangle are (3, 1), (3, 5), (6, 5), and (6, 1). Find the perimeter of the rectangle
Sergio039 [100]

Answer:

14units

Step-by-step explanation:

Let the vertices of a rectangle be A(3, 1), B(3, 5), C(6, 5), and D(6, 1).

Using the formula for calculating distance between two points;

AB =√(5-1)²+(3-3)²

AB = √4²

AB = 4

BC = √(5-5)²+(6-3)²

BC = √3²

BC =>3

CD = √(1-5)²+(6-6)²

CD = √(-4)²

CD = √16

CD = 4

AD= √(1-1)²+(6-3)²

AD = √3²

AD = √9

AD =3

Perimeter of the rectangle = AB+BC+BD+AD

Perimeter of the rectangle = 4+3+4+3

Perimeter of the rectangle = 14units

One number exceeds another number by 6. One fourth of the sum of the two numbers is two less than the smaller.
dolphi86 [110]

Answer:

7 and 13

Step-by-step explanation:

let the 2 numbers be x and y , x > y , then

x = y + 6 → (1)

\frac{1}{4} (x + y) = y - 2 ( multiply both sides by 4 to clear the fraction )

x + y = 4y - 8 ( subtract 4y from both sides )

x - 3y = - 8 → (2)

Substitute x = y + 6 into (2)

y + 6 - 3y = - 8

- 2y + 6 = - 8 ( subtract 6 from both sides )

- 2y = - 14 ( divide both sides by - 2 )

y = 7

Substitute y = 7 into (1)

x = 7 + 6 = 13

The 2 numbers are 7 and 13
