S_A_V [24]

The number of pieces made from rod is 49

<h3><u>Solution:</u></h3>

Given that A metal rod will be cut into pieces that are each 1/56 meters long

The rod is 7/8 meters long.

<em><u>To find: number of peices made from rod</u></em>

The number of peices made from rod can be calculated by dividing the total length of rod by length of each piece

\text {number of pieces made }=\frac{\text {total length of rod }}{\text { length of each piece}}

Here total length of rod = \frac{7}{8} meters

length of each piece to be made = \frac{1}{56} meters

Substituting the values in above formula, we get

\text {number of pieces made }=\frac{\frac{7}{8}}{\frac{1}{56}}=\frac{7}{8} \times \frac{56}{1}

\text {number of pieces made }=7 \times 7=49

So the number of pieces made from rod is 49

20 POINTS PLEASE HELP ASP D:
Butoxors [25]

Hi there!

When two lines intersect, we know that the ones on the opposite sides are equal to one another. Thus, we know that the angle opposite of the one marked with 90 degrees (on the other side of the intersection) is also 90 degrees.

We know that a full turn is 360 degrees. We can see that the two 90 degrees make up part of the turn, and the other pair of angles, both of which are equal to x (as per the reasoning above), make up the rest. We know that the two 90 degrees, added together, is equal to 180 degrees. This means, after subtracting 180 from 360, that 180 degrees are remaining that aren't the 2 90 degrees, and are make up of two angles both measuring x degrees.

As we know that they both measure x, then we know that we say 2x = 180, which gives us x = 90.

Hope this helps!

Please factor 5x^2-23x+12
STALIN [3.7K]

5x^2-23x+12

= 5x^2 - 20x - 3x +  12

= 5x(x - 4) - 3(x - 4)

= (5x - 3)(x - 4)

Hope that helps

I have 3 questions for math
Airida [17]

Answer:

  1. no question content
  2. (x, y) = (1/2, 4)
  3. (x, y) = (2, 10)

Step-by-step explanation:

1. No link, no question

__

2. Divide the first equation by 2 and substitute for y using the expression in the second equation.

  2x +(4x+2) = 5

  6x = 3 . . . . . . . . . subtract 2

  x = 3/6 = 1/2 . . . . divide by2

  y = 4(1/2) +2 = 4 . . . . substitute into the equation for y

The solution is (x, y) = (1/2, 4).

__

3. The solution using a graphing calculator is (x, y) = (2, 10). (see attached)
