The perimeter of a square can be obtained by adding the length of each side. If the perimeter is 5.5 mm, the perimeter equals 22 mm. If the sides are dilated by a factor of 11, the new perimeter is (5.5mm+11)*4 = 66 mm. This is the new perimeter after dilation

The length of a rectangle is 4 centimeters more than twice its width of the perimeter of the rectangle is 86centimeters find the

lana66690 [7]

Answer:

$Width= 13 cm$

$length=30cm$

Step-by-step explanation:

Let the length of the rectangle be 'L'

And the width of the rectangle be 'W'

$Perimeter= 86 cm$

According to the statement:

$Length= 2*Width+4\\L=2W+4$

Perimeter of a rectangle= 2(Length+Width)

$86=2(2W+4+W)\\86/2=3W+4\\43=3W+4\\3W=43-4\\3W=39\\W=39/3\\W=13 cm\\\\Length(L)=2W+4\\=2(13)+4=26+4=30 cm\\Length=30 cm$

$Width= 13 cm$

$length=30cm$

Area of the triangle base: (1/2)*3.3*x
area of the cone base: pi*3*3
they are equal, so 9pi=(1/2)*3.3x
x=17.1

Find an equation of the line that has the given slope and contains the given point. m=7/3 (1,6)

iris [78.8K]

The point-slope form:

$y-y_1=m(x-x_1)$

We have the point (1, 6) and the slope m = 7/3. Substitute:

$y-6=\dfrac{7}{3}(x-1)$ <em>use distributive property</em>

$y-6=\dfrac{7}{3}x-\dfrac{7}{3}$ <em>add 6 to both sides</em>

$y=\dfrac{7}{3}x+\dfrac{11}{3}$ <em>multiply both sides by 3</em>

$3y=7x+11$ <em>subtract 7x from both sides</em>

$-7x+3y=11$ <em>change the signs</em>

$7x-3y=-11$

Answer:

point-slope form: $y-6=\dfrac{7}{3}(x-1)$

slope-intercept form: $y=\dfrac{7}{3}x+\dfrac{11}{3}$

standard form: $7x-3y=-11$

Answer:

n = 8

Step-by-step explanation:

(n−2) × 180 is the formula to find the interior angles of a polygon

(n−2) × 180 = 1080

Divide each side by 180

(n−2) × 180/180 = 1080/180

n-2 =6

Add 2 to each side

n-2+2 = 6+2

n = 8
