A builder wants to build the bridge whose cross section is shown in the diagram. Two companies offer simple bids on building the
leva [86]

The length of the bridge is the distance from the beginning to the end.

<em>The distance b between each beam is 9ft.</em>

Let:

<em />I \to<em> I-Beam</em>

<em />d_I \to<em> distance between I beam and the bridge</em>

<em />b \to<em> distance between each I beam</em>

<em />

Given that:

I = \frac 34 ft\\

d_I = 3 ft

<em />Length = 55ft\ 6in<em> --- length of the  bridge</em>

<em />

From the diagram (see attachment), there are: 6 I-beams.

So, the length of the 6 I-beams is:

L_1 = 6 \times I

L_1 = 6 \times \frac 34

L_1 = \frac {18}4

L_1 = 4.5ft

There are 2 I-beams beside the bridge

So, the distance between the 2 I-beams and the bridge is:

d_1 =2 \times d_I

d_1 =2 \times 3ft

d_1 =6ft

There are 5 spaces between the I-beams

So, the length of the total spaces is:

L_2 = 5 \times b

L_2 = 5b

The total length is:

Length = L_1 + d_1 + L_2

So, we have:

4.5ft + 6ft + 5b = 55ft\ 6in

Collect like terms

5b = 55ft\ 6in - 4.5ft - 6ft

5b = 44.5ft\ 6in

Convert inches to feet

5b = 44.5ft\ + \frac{6}{12}ft

5b = 44.5ft\ + 0.5ft

5b = 45ft

Divide both sides by 5

b = 9ft

<em>Hence, the distance (b) between each beam is 9ft.</em>

Simplify the inequality:<br> -12.4x+8x &gt; -0.4x-5.2-2.7
ad-work [718]

Answer:

<h3><u>x < 1.975</u></h3>

Explanation:

-12.4x + 8x > -0.4x - 5.2 - 2.7

<em>Add similar elements: -12.4x + 8x = -4.4x</em>

-4.4x > -0.4x - 5.2 - 2.7

<em>Subtract -5.2 - 2.7: -7.9</em>

-4.4x > -0.4x - 7.9

<em>Multiply both sides by 10</em>

-4.4x · 10 > -0.4x - 7.9 · 10

<em>Refine</em>

-44x > -4x - 79

<em>Add 4x to both sides</em>

-44x + 4x > -4x - 79 + 4x

<em>Simplify</em>

-40x > -79

<em>Multiply both sides by -1 (Reverse the inequality)</em>

-40x (-1) > -79 (-1)

<em>Simplify</em>

40x < 79

Divide both sides by 40

40x / 40 < 79 / 40

<em>Simplify</em>

x < ⁷⁹⁄₄₀

<em>Turn the fraction into a decimal</em>

<h3><u>x < 1.975</u></h3>
