Answer:

ABCD is a rhombus => AC is perpendicular with BD

=> AC = 2(2n + 5) = 30

<=> 2n + 5 = 15

=> n = 5

with n = 5 => AC/2 = 15

BD/2 = 4.5 - 3 = 17

BC² = (AC² + BD²)/4 = 514/4 = 128.5

=> BC = 11.34

Answer:

Step-by-step explanation:

The question is what does 2n + 5 represent? Is it 1/2 the line or all of AC. There seems to be a run on ambiguous questions. I'm going to assume that 2n + 5 is AC -- all of it. And 4n-3 is all of BD.

AC = 30

2n + 5 = 30      Subtract 5 from both sides.

2n = 30 - 5

2n = 25            Divide by 2

n = 25/2

n = 13.5

====================

BD = 4n - 3

BD = 4*13.5 - 3

BD = 54 - 3

BD = 51

Answer:

BD = 32.5

Step-by-step explanation:

Since this is a square, the length of all the sides are equal. So line AB = BC = CD = DA = 23

Additionally, all the interior angles are the same (90°)

To find the length of BD, you can cut the square in half diagonally to form two right angled triangles, ABD and BCD.

For either one, BD is the hypotenuse of the right angled triangle so we can use Pythagoras' theorem to solve for the that (since we also know the legnth of the sides)

a = 23

b = 23

c = BD, which we have to find

[tex]a^{2} +b^{2} =c^{2} \\23^{2} +23^{2} =c^{2} \\\sqrt{23^{2} +23^{2} } = c\\\sqrt{529+529} =c\\\sqrt{1058} = c\\32.5 = c[/tex]

therefore the length of BD is 32.5

hope this helps!

Answer:

[tex]16*(\frac{1}{2})^x[/tex]

Step-by-step explanation:

our equation will look something like this

abˣ=y

We can write the two equations

4=ab²

and

2=ab³

we can divide the second equation by the first and get

[tex]\frac{2}{4}=\frac{ab^3}{ab^2}\\\\=.5=b\\[/tex]

Now that we know what b equals we can plug that value in and solve for a

[tex]4=a*.5^2\\\\a=16[/tex]

Answer:

Explanation:

|4b + 4| = |2b + 8|

Solve absolute value

|4b + 4| = |2b + 8|

Either 4b + 4 = 2b + 8 or 4b + 4 = −(2b + 8)

4b + 4 = 2b + 8 (Possibility 1)

4b + 4 − 2b = 2b + 8 − 2b (Subtract 2b from both sides)

2b + 4 = 8

2b + 4 − 4 = 8 − 4 (Subtract 4 from both sides)

2b = 4

2b / 2 = 4 / 2 (Divide both sides by 2)

b = 2

4b + 4 = −(2b + 8) (Possibility 2)

4b + 4 = −2b − 8 (Simplify both sides of the equation)

4b + 4 + 2b = −2b − 8 + 2b (Add 2b to both sides)

6b + 4 = −8

6b + 4 − 4 = −8 − 4 (Subtract 4 from both sides)

6b = −12

6b / 6 = -12 / 6 (Divide both sides by 6)

b = -2

Answer:

1. 12.6  2. 21.4

Step-by-step explanation:

1. c=2piR, so if the radius is 2, then 2 times 2 then times 3.14= 12.6(rounding to the nearest tenth)

2.i already explained the formula, so it should be 3.4*2 then times 3.14= 21.4

Answer: $64.20

Step-by-step explanation:

Cost of shoe = $60

Sales tax rate = 7%

Sale tax = 7% × $60 = 7/100 × 60 = $4.20

The total price paid by Mary

= Cost of shoe + Sales tax

= $60 + $4.20

= $64.20

Answer:

  64/109 ≈ 0.5872

Step-by-step explanation:

41 + 23 = 64 of the events have outcome E.

An additional 35 + 10 = 45 do not.

The probability of an outcome of E is 64 out of a total of 64+45 = 109 events.

  P(E) = 64/109 ≈ 0.5872
