Find The Perimeter And Area Of The Figure If Each Unit On The Graph Measures 1 Centimeter. Round Answers

Answers

Answer 1

Answer:

Area = 16 cm²

Perimeter = 20.9 cm

Step-by-step explanation:

To find the perimeter and area of the given triangle length of all sides of the given triangle will be required.

Use the formula to determine the distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],

d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Distance between A(0,9) and B(4, 9),

AB = [tex]\sqrt{(4-0)^2+(9-9)^2}[/tex] = 4 cm

Distance between A(0,9) and C(0, 1),

AC = [tex]\sqrt{(0-0)^2+(9-1)^2}[/tex]

AC = 8 cm

Distance between B(4, 9) and C(0, 1),

BC = [tex]\sqrt{(4-0)^2+(9-1)^2}[/tex]

BC = [tex]\sqrt{16+64}[/tex]

     = [tex]\sqrt{80}[/tex]

     = [tex]4\sqrt{5}[/tex]

     = 8.9 cm

Area of ΔABC = [tex]\frac{1}{2}(\text{AC})(\text{AB})[/tex]

                        = [tex]\frac{1}{2}(8)(4)[/tex]

                        = 16 cm²

Perimeter of the triangle = AB + AC + BC

                                         = 4 + 8 + 8.9

                                         = 20.9 cm

Step-by-step explanation:

line I is the perpendicular bisector of MN. find m

Answers

Answer:

m = 68

Step-by-step explanation:

MN bisects it or splits it in half so we know N = M, which we could also write as 8x-12 = 5x+18 because they give us those equations

once you have 8x-12 = 5x+18 you can subtract 5x from both sides, so you will get 3x-12 = 18, then you can add 12 to both sides and you will get 3x = 30. Once you have narrowed down to this you can divide three by both sides making x = 10

Now that we know x =10 we can insert it into the equation

5(10) + 18 = m

50 + 18 = m

m = 68

I do not know which formula to use

Carla bought a dress at a sale for 20% off the original price. The sale price of the dress was $68.90. Find the original price of the drees, in dollars.


Step by step explanation please.

Answers

Answer:

I think it's the second formula.

Step-by-step explanation:

Let x be the original price.

The discount rate is 20%

Sale Price is $68.90

Discount = 20% of x = 0.2x

Using the formula, Sale Price = Original Price - Discount,

Original Price - Discount is x-0.2x = 0.8x

$68.90 = 0.8x

From here on, just do the equation :) Hope this helps!

slove this?
​

Answers

I think it’s 3,996.35 if you use PEMDAS and you multiply 74 by 54 to get 3,996 then you divide 7 over 20 to get .35 and you then add them together to get 3996.35
74 x 54 = 3,996

7\ 20 = 0.35

3,996 + 0.35 = 3,996.35

Question 5 please. I need help with thus.

Answers

Answer:

TU = 63.84 in

Step-by-step explanation:

Since T lies on RU, then

RT + TU = RU, substitute values

9x - 2.64 + 11x - 4.36 = 117, that is

20x - 7 = 117 ( add 7 to both sides )

20x = 124 ( divide both sides by 20 )

x = 6.2

Thus

TU = 11x - 4.36 = 11(6.2) - 4.36 = 68.2 - 4.36 = 63.84 in

The length of TU is 63.84

EASY 10 POINTS QUESTION 7 PLEASEEEEEEE

Answers

Answer:

x=9

Step-by-step explanation:

-2x+9=-4x+27

first you want to get the -4x on the other side of the equal sign you do that by -4- -4 which will cancel them out and you do -2 - -4 = 2x

now you have 2x+9=27 now you do 9-9 which will cancel them out and you do 27 - 9 = 18

Now you have 2x=18 then you want to divide 2 by 2x which will cancel out the 2 and you want to divide 2 by 18 which equals 9 so you answer is x=9

Which of the following is equivalent to 5x-6y=20?

A y=5/6x
B y=5/6x-10/3
C y=6/5x+4
D y=-5/6x​

Answers

Answer:

y =  [tex]\frac{5}{6}[/tex]x - [tex]\frac{10}{3}[/tex]

Step-by-step explanation:

Given expression:

               5x  - 6y = 20

To solve this problem, we make y the subject of the expression:

     Solution

              5x  - 6y = 20

      Add -5x to both sides of the expression;

              -5x + 5x - 6y = 20 + (-5x)

                             -6y  = 20 - 5x

     Now, multiply both sides by [tex]-\frac{1}{6}[/tex] ;

              [tex]-\frac{1}{6}[/tex]  x (-6y) =  [tex]-\frac{1}{6}[/tex] (20 - 5x )

                         y  = [tex]-\frac{20}{6}[/tex] + [tex]\frac{5}{6}[/tex]x

                         y =  [tex]\frac{5}{6}[/tex]x - [tex]\frac{10}{3}[/tex]
