A piece of cable 8.5 cm long weighs 52 grams. How much does a cable that is 10 cm long weigh
Arturiano [62]
8.5 cm cable weighs = 52 grams

1 cm of cable weighs = \frac{52}{8.5}grams
                                      
                                      = 52/ \frac{85}{10} grams
                                      = 52* \frac{10}{85} grams
                                      = \frac{520}{85} grams
                                      = 6.11764 grams
Rounding it up = 6. 10000 grams

Then, 

10 cm of cable weighs = 6.10*10 grams
                                            <span>    </span>= 61.0 grams

Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify.</em>

-3(x + 2) = 16 - x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Distributive Property] Distribute -3:                                                                -3x - 6 = 16 - x
  2. [Addition Property of Equality] Add <em>x</em> on both sides:                                     -2x - 6 = 16
  3. [Addition Property of Equality] Add 6 on both sides:                                    -2x = 22
  4. [Division Property of Equality] Divide -2 on both sides:                                x = -11

New #6 find the value of x. Round answer to nearest tenth.
bija089 [108]

This is a right triangle. We know that

                                                  \sin x = \frac{\text{opposite side}}{\text{hypotenuse}}

Therefore,

                                            \sin x = \frac{15}{20} = \frac{3}{4} = 0.75

Now we have:

                                                    x=\sin^{-1}0.75

                                                         x=48.6

Guys, I’m giving you at least 100 points for you to answer to my angles, triangles, and quadrilaterals word problem homework pac
frez [133]

Step-by-step explanation:

For question 22: Notice the congruent symbol on sides AB and CB; this shows that the triangle is isosceles, and in an isosceles triangle, the angles opposite congruent sides are congruent. Thus, angle A actually equals angle C.

In other the find B, it is know that all of the interior angles of a triangle must add to 180; thus, this can be written as: angle A + angle B + angle C = 180.

Since you already know angles A and C, subtract angle A and angle C from 180 to get angle B.

For question 23:

Notice that triangle DBC is an isosceles triangle, and that angle D and angle C are opposite of congruent sides, indicating that they are equal. Since the interior angles of a triangle must add up to 180, and you know that angle D equals angle C, you can find angle DBC by doing 180 - (2 * angle D).

Now that you have angle DBC, you can find angle CBA; since these two angles form a straight line, you know they must add to 180 degrees. Thus, 180 - angle DBC equals angle CBA.

Now, notice that triangle CBA is also isosceles, and that angles CBA and angle A are opposite congruent sides, indicating that they are also congruent. Thus, angle A equals angle CBA.

Hope this helps :)
