So a deckameter is = to 10 meters

just multiply it

3*10= 30
then divide

30/1= 30

So glenn needs 30 meter paces of ribbon

Step-by-step explanation:

Recall that for a quadratic equation y = ax² + bx + c in the X-Y plane, the x-location of the vertex (i.e maximum or minimum point) is given by

x @vertex = -b/2a

in this case your quadratic equation is

h = 4 + 20t - 5t²   (rearranging in the form y = ax² + bx + c )

h = - 5t² + 20t + 4

hence a= -5, b = 20 and c = 4

applying the formula for vertex

t @ vertex = -b  /2a = -(20) / (2)(-5) = -20/-10 = 2

therefore t = 2

Suppose you can work a total of no more than 38 hours each week at your two jobs. Housecleaning pays $7 per hour and your retail
MA_775_DIABLO [31]

Answer:

<u>The system of inequalities is:</u>

<u>7x + 8y ≥ 280</u>

<u>x + y ≤ 38</u>

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Amount of weekly hours you can work, no more than 38 hours (≤ 38)

Rate at housecleaning per hour = US$ 7

Rate at retail job per hour = US$ 8

Salary per week, at least US$ 280 (≥ 280)

2. Complete the system of linear inequalities to model this situation.

x = Number of hours per week worked at housecleaning job

y = Number of hours per week worked at retail job

Now, we have:

7x + 8y ≥ 280 (Total of salary of the two jobs should be at least US$ 280), where 7x is the salary received from housecleaning job and 8y is the salary received from retail job

x + y ≤ 38 (You can't work more than 38 hours per week)

Answer:

The answer to your question is below

Step-by-step explanation:

Process

1.- Get two points of each line to find the equation of each line

   Continuous line    A (-10, 0)  B (0, 9)

   Dotted line            C (-2, -3)   D (0, -10)

 Slope continuous line    m = \frac{9 - 0}{0 + 10} = = \frac{9}{10}

 Slope dotted line     m = \frac{-10 + 3}{0 + 2} = \frac{-7}{2}

2.- Get the equation of each line

     Continuous line    y + 0 = 9/10 (x + 10)

                                   y = 9/10x + 9

      Dotted line          y + 3 = -7/2(x + 2)

                                    y + 3 = -7/2x - 7

                                    y = -7/2x -7 - 3

                                    y = -7/2x - 10

3.- Find the inequalities

   <u> Continuous line</u> (we need the upper area of the line, we use ≥)

                               y ≥ 9/10x + 9

   The <u>Dotted line</u> (we also need the upper area, we use >)

                              y > -7/2x - 10
