What is the value of X?
Intersecting Chords (Lengths)

Answer:

Step-by-step explanation:

QA = QC = 5.9    ⇒    PA = 27.4 - 5.9 = 21.5

PB = PA = 21.5

CR = BR = 12.2

So, the perimeter:

P = 27.4 + 5.9 + 2×12.2 + 21.5 = 79.2

The perimeter of the triangle PQR is 79.2 units.

Perimeter of a straight sided figures or objects is the total length of it's boundary.

Given a triangle PQR.

An incircle is drawn inside the triangle.

We know that the length of the tangents which are drawn from an exterior point to the circle are equal.

Using this property and the given lengths,

PQ = 27.4

PR = (27.4 - 5.9) + 12.2 = 33.7

QR = 5.9 + 12.2 = 18.1

Perimeter of the triangle = 27.4 + 33.7 + 18.1 = 79.2 units

Hence the perimeter is 79.2 units.

Answer:

our inputs are 3 & 1/2

Step-by-step explanation:

the ? is the slope and the slope is equal to 1/2 so

?=1/2

the point slope formula is

(y-y1)=m(x-x1)  (x1,y1)--> a point on the line  m--> slope

so we chose (x1,y1) as (3,0)

when we plug that in we get

y-0=1/2(x-3)

so our inputs are 3 & 1/2

Step-by-step explanation:

you are a very nice person for helping your mom. good luck for this!

ok let's work on question 7 first.

$63.99 is the cost of a skateboard.

  15% of 63.99 = 10% + 5%

  10% of 63.99 = 6.399          (move the decimal one place to the left)

   5% of 63.99 = 1/2 of 6.399

     1/2 x 6.399 = 3.1995

6.399 + 3.1995 = 9.5985

ok, so that's 15% of 63.99

now we need to take away 9.5985 from 63.99

63.99 - 9.5985 = 54.3915

the discount price of the skateboard is $54.3915

a further 10% is $5.43915

so take off that from the discount,

54.3915 - 5.43915 = 48.95235

the final price is $48.95235

QUESTION 8

         shop A = 6.95 x 40

     6.95 x 40 = $278

         shop B = 20% of 325

20/100 * 325 = 65

      325 - 65 = 260

therefore, shop B is cheaper.

hope this helped, good luck!

Complete question :

The Hiking Club is taking another trip. The hike leader's watch shows that they gained 296 feet in altitude from their starting position. Their altitude is now 285 feet, but there is no record of their starting altitude. Write and solve an equation to represent this situation and find their starting altitude.

Answer:

Expression :

285 = x + 296

Starting altitude, x = - 11 feets

Step-by-step explanation:

Let starting position = x

Altitude gained = 296 feets

Final attitude = 285 feets

The starting altitude could be obtained by the expression :

Final altitude = starting altitude + Altitude gained

285 = x + 296

Solve for x, to obtain starting altitude ;

285 - 296 = x + 296 - 296

-11 = x

Hence, starting altitude is - 11 feets

Answer:

x = -4 + 3√2 and x = -4 - 3√2

Step-by-step explanation:

Complete the square of x^2+8x-2=0:

Between 8x and -2, write in 4^2 - 4^2, so that we now have:

x^2 + 8x + 16 - 16 - 2 = 0, or by writing x^2 + 8x + 16 as the square of a binomial, (x + 4)^2 = 18

Taking the square root of both sides, we get:

x + 4 = √18 = ±√9√2, or ±3√2

Then x = -4 + 3√2 and x = -4 - 3√2
