If each of the 8 sides of an octagon is 25 centimeters long, then the perimeter of the octagon is how many meters?

Answers

Answer 1

Answer: total number of sides of a octagon =8
measure of 1 side= 25 cm
perimeter=8 x 25=200 cm

Answer 2

Answer: 200 because 25 x 8 = 200 because perimeter is the outside it =)

A rectangle with sides of lengths 1/3 yard and 3/4 yard what's the area

Answers

The area of any rectangle is

   Area = (length) x (width) .

For this one, Area = (1/3 yard) x (3/4 yard)

   = (1/3 x 3/4) yard²

   =    1/4 yard² .

If you would like to know what is the area, you can calculate this using the following steps:

area = width * length
area = 1/3 yard * 3/4 yard = 1/4 square yard

The area would be 1/4 square yard.

The line passing through (11,y) and (2,0)is parallel to the line joining (7,5) and (-2,2). Find y.

Answers

Answer: y = 3

Step-by-step explanation:

Two lines are said to be parallel if they have the same slope. All we need to do is to find the slope of each line . The formula for finding slope is given as :

m = $(y_(2)-y_(1))/(x_(2)-x_(1))$

For the first line

$x_(1)$ = 11

$x_(2)$ = 2

$y_(1)$ = y

$y_(2)$ = 0

substituting into the formula , we have

m = $(0 - y)/(2 - 11)$

m = $(-y)/(-9)$

m = $(y)/(9)$

Also Finding the slope of the second line we have

$m_(2)$ = $(2-5)/(-2 - 7)$

$m_(2)$ = $(-3)/(-9)$

$m_(2)$ = $(1)/(3)$

Since the two lines are parallel , we will equate their slope , that is

$(y)/(9)$ = $(1)/(3)$

3y = 9

y = 3

What is 5d=470 and what is 8a=47

Answers

5d=470:

in this case we have to divide both sides by 5:

d=94

8a=47:

in this case we have to divide both sides by 8:

a=5.875

as a general rule, if you want to find out a value of a in
ab=c

you have to divide both sides of the equation by b (if it's not zero); then you will have left:

a=c/b

and if you calculate c/b, this will give you the answer

$5d= 470 \n \n d=470:5 \n \n \boxed{\boxed{d= 94}} \n \n 8a=47 \n \n a=47:8 \n \n \boxed{\boxed{a=5.875}}$
