1. What is the length of (AB)?


2. What is the length of (BC)?


3. What is the perimeter of this rectangle?

Answers

The length of AB is 4.12 units, length of BC is 8.25 units and Perimeter of rectangle ABCD is 24.74 units.

What is Perimeter of Rectangle?

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Here,

A (-3, 3) and B (1, 4)

then, Length of AB = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

                               = [tex]\sqrt{(1-(-3))^2+(4-3)^2 }[/tex]

                               = [tex]\sqrt{4^2 + 1^2}[/tex]

                               = [tex]\sqrt{17}[/tex] units.

                               = 4.12 units

B (1, 4) and C (3, -4)

then, Length of BC = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
                                = [tex]\sqrt{(3 - 1)^2+(-4 - 4)^2 }[/tex]

                                = [tex]\sqrt{4 + 64}[/tex]

                                = [tex]\sqrt{68}[/tex]

                                = 8.25 units

Perimeter of Rectangle = 2 ( AB + BC )

                                        = 2 ( 4.12 + 8.25 )

                                        = 2 X 12.37

                                        = 24.74 units

Thus, the length of AB is 4.12 units, length of BC is 8.25 units and Perimeter of rectangle ABCD is 24.74 units.

Answers

Because this is a right triangle, we can use a trigonometric function to solve for the missing side.

Remember: SOH-CAH-TOA

We are given an angle, as well as the adjacent side and hypotenuse. Therefore, we should use the cosine function to solve for x.

cos(67) = x / 15

x = cos(67) * 15

Step-by-step explanation:

1) Expand the square

2) Distribute
3) Distribute

4) Distribute

5) Combine like terms

6) Add the numbers

7) Move terms to the left side

8) Subtract the numbers

9) Use the quadratic formula

10) Simplify

11) Separate the equations

12) Solve

Therefore, the solution of this equation is x = -3 + √42

(x + 3)² + 4 = 46

(x + 3)² = 42

x + 3 = ±sqrt(42)

x = ±sqrt(42) - 3

x1 = sqrt(42) - 3 = 3.480740698...

Answer:

8/9n - 3

Step-by-step explanation:

The answer is 8/9n - 1 1/3.

Explanation:

When multiplying a fraction by a whole number, you multiply the numerator by the whole number. In this case, doing so would result in 8/9n. Because the same principle would apply for the other part of the equation, we can do 4/9 x -3 to get -12/9. -12/9 is improper, so we could standardize it to get the equation’s expression in simplified form. -12/9 simplified is -1 1/3. The answer would be 8/9n - 1 1/3 because when there is a negative factor, the expression becomes a subtraction problem. Thus, your equation is 8/9n - 1 1/3.

y = 2x − 5
y = -6x + 3
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution.

Part B: Check your work. Verify your solution and show your work.

Part C: If the two equations are graphed, what does your solution mean?

Answers

Answer:

Part A

Solve by substitution.

Given equations:

y = 2x − 5y = -6x + 3

⇒ 2x - 5 = -6x + 3

⇒ 2x - 5 + 5 = -6x + 3 + 5

⇒ 2x = -6x + 8

⇒ 2x + 6x = -6x + 8 + 6x

⇒ 8x = 8

⇒ 8x ÷ 8 = 8 ÷ 8

x = 1

To find y, substitute the found value of x into one of the equations:

⇒ y = 2(1) - 5

⇒ y = 2 - 5

⇒ y = -3

Therefore, the solution is (1, -3)

Part B

Substituting x = 1 into the equations:

y = 2x − 5

⇒ y = 2(1) − 5

⇒ y = 2 − 5

⇒ y = -3

y = -6x + 3

⇒ y = -6(1) + 3

⇒ y = -6 + 3

⇒ y = -3

When x = 1, both equations return a y-value of -3.  Therefore, the solution is verified.

Part C

If the two equations are graphed, the solution will be the point of intersection.

Answers

Answer:

They bought 6 vanilla wafers and 21 chocolate, they add up to 27.

x = amount of vanilla wafers

y = amount of chocolate wafers.

4x+y = 45

x+y= 27

Step-by-step explanation:

x = amount of vanilla wafers

y = amount of chocolate wafers

Vanilla wafers = 4$ each

Chocolate wafers = 1$ each.

So, 4x+y = 45 and x+y= 27 because they spent 47$ on 27 packs.

With both equations we can substitute.

1. Change one equation so one variable is on one side

x+y = 27 to y = 27-x

2. Substitute the variable from the other equation.

4x+y = 45 to 4x+27-x = 45

3. Solve the equation for x.

4x+27-x = 45

3x+27 = 45

3x = 18

x = 6 (amount of vanilla wafers)

4. substitute with equation.

y = 27-x to y = 27-6

5. Solve the equation for y.

y = 27-6

y = 21 (amount of chocolate wafers)

Yellow: (2/5) * (1/3)

Purple: (3/10) * (6/19)

Blue: (1/4) * (13/51)

Step-by-step explanation:

 Green:

>> Maria has 11 letters in her bag, and 2 of them are B's.

>> At first, the chance of drawing a B is 2 out of 11: 2/11.

>> Let's assume that everything goes according to plan, and she actually draws a B.

>> Then she has 10 letters, and only one of them is B (she already has the other one).

>> That means that the chance of drawing that B is 1 out of 10: 1/10.

>> Thus, (2/11)*(1/10).

 Yellow:

>> There are 11 + 13 + 16 = 40 items in the closet.

>> The probability of selecting a prop is 16/40 = 2/5 (there are 16 props and 40 items).

>> That means that there are 40-1=39 items left.

>> Therefore, the probability of selecting a costume is 13/39 = 1/3 (as there are 13 costumes and 39 items).

>> The answer is (2/5) * (1/3).

 Purple:

>> There are 6+8+6=20 jellybeans.

>> At first, Hannah grabs an orange candy (there are 6 of them): 6/20 = 3/10.

>> Then there are 19 candies left.

>> Then she grabs a pink one (there are 6 of them): 6/19.

>> The answer is (3/10)*(6/19).

 Blue:

>> There are 52 cards in a standard deck, 13 clubs, 13 spades, 13 hearts, 13 diamonds.

>> The 1st is a spade: 13/52 = 1/4.

>> There are 51 cards left.

>> The 2nd is a club: 13/51.

>> (1/4)*(13/51).

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Let's suppose the total cost is $x if Jocelyn purchase cake from store A:

x = 1.50×150 + 25

x = 225+25 = $250

Let's suppose the total cost is $y if Jocelyn purchase cake from store B:

y = 2.25×150

y = $337.5

Difference between total cost = 337.5 – 250 = $87.5

Thus, the Jocelyn needs to pay $87.5 if Jocelyn order cakes from store B if store A charges $1.50 per serving plus a $25.00 delivery charge. Store B charges $2.25 per serving and no delivery charge.
