bekas [8.4K]

Answer:

Andres has 12 stars.

Step-by-step explanation:

  • 3 stars - 1 goal
  • -3/4 stars - Missed goal
  • Scored 5
  • Missed 4

3 * 5 = 15

He has 15 stars but then misses 4 goals.

3/4 * 4 = 3

He loses 3 stars becuase he missed 4 goals.

15 - 3 = 12

He ends with 12 stars.

Shera is building a cabinet she is making wooden braces for the corners of the cabinet. What is the surface area
MA_775_DIABLO [31]
The correct answer for the question that is being presented above is this one: "28 in^2." 

We have to get the individual area of each surface.
A1 = 1*3*2 = 6
A2 = 1*3*2 = 6
A3 = 1*2*2 = 4
A4 = 2*3*2 = 12
Area = A1 + A2 + A3 + A4 
Area = 6 + 6 + 4 + 12
Area = 28 in^2

A packaging company is planning is in the planning stages of creating a box that include a three dimensional support inside the
Oliga [24]

Answer:

The length of the diagonal support is 69 feet.

Step-by-step explanation:

Dimensions of the box: length = 6 feet

                                       width = 5 feet

                                       height = 8 feet

The diagonal support relates with the diagonal of the base and the height.

From the base of the box, let the length of its diagonal be represented by x. Applying Pythagoras theorem;

/Hyp/^{2} = /Adj 1/^{2} + /Adj 2/^{2}

x^{2} = 6^{2} + 5^{2}

x^{2} = 36 + 25

   = 61

x = \sqrt{61}

  = 7.81

let the length of the diagonal support be represented by l. So that;

/Hyp/^{2} = /Adj 1/^{2} + /Adj 2/^{2}

l^{2} = x^{2} + 8^{2}

  = \sqrt{61} + 64

l  = \sqrt{\sqrt{61} + 64 }

  = 61 + 8

  = 69

Thus, the length of the diagonal support is 69 feet.
