Answer:

10√2

Step-by-step explanation:

A(1, 4), B(3, 6), C(6, 3), D(4, 1)

The distance formula tells you the distance d between two points (x1, y1) and (x2, y2) is given by ...

d = √((x2-x1)² +(y2-y1)²

Then the side lengths are ...

AB = √(2² +2²) = √8 = 2√2

BC = √(3² +(-3)²) = √18 = 3√2

The perimeter is twice the sum of these sides, so is ...

P = 2(2√2 +3√2) = 10√2 . . . the perimeter of the rectangle

If the line is perpendicular, that means the slope has to be opposite, so it will have a slope of -1/2

Fill in the point that it has to pass through on y and x

1=-1/2(0) + b

1=0+b

1=b

Then go back to the standard form y=mx + b and fill in the slope and y intercept

Y= -1/2x + 1

6x+2y=12 solve for y,state the m and b,and graph

kramer

Move 6x to the right side: 2y=12-6x
Divide both sides by 2: y=6-3x
m is the slope which in this case is -3
To see a graph plug y=6-3x into the website wolfram alpha!
Hope this helps!!

Answer: The cost for 20 people equals $180.

Step-by-step explanation:

Given: It costs $100 to rent the bowling alley, plus $4 per person.

The cost for any number (n) of people can be found using the expression

$100+4n$

We can find the cost for 20 people by substituting n=20 in the above expression, we get

$100+4(20)=100+80=180$

Hence, The cost for 20 people equals $180.

You know that the rose garden is 20% of the total garden. What is 20% written as a ratio?

astraxan [27]

Answer:

20:100

Step-by-step explanation:

We know that percentages are out of 100. The rose garden is 20 percent of the garden. Which is 20 percent/100 percent. A ratio says how much of one thing there is compared to another thing. Therefore we are comparing 20:100. You can also simplify this ratio to 1:5
