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

6a+10= 130

6a=120    a=20   so now we plug it in 6(20) +10= 130

26.   4a-4=2a+30

      2a=34      a=17   sso now we plug in 4(17)-4= 64    2(17)+30= 64

27.    6y+1=4y+9                             2x-5=x+7

          2y=8                                      x=2

         y=4

now plug in 6(4)+1=25     4(4)+9=25     2(2)-5= -1     (2)+7=9

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.

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!

Answer:

Jacob has a part-time job at an ice skating rink selling hot cocoa. He decided to plot the number of hot cocoas he sold relative to the day's high temperature and then draw the line of best fit. Based on the line of best fit, what would you predict the day’s high temperature to be if Jacob sold 89 hot cocoas?

Step-by-step explanation:

Parker would sell 93 hot cocoas.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

From the Curve we can write

slope = (101 - 105) / (5- 0)

slope = -4/5

so, the equation to represent the situation is

= -4/5t + 105

= -0.8t + 105

Now, if t= 15 then

s= -12 + 105

s = 93

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

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
