I'm assuming that the pitch of this roof is in fact its slope...

Slopes are basically tangents...

tan(x)=Opposite/Adjacent

-------

tan(x)=9/7

-------

This means that the answer is D), 9/7.

Answer:

D. \frac{9}{7}

Step-by-step explanation:

We have been given that the pitch of a roof that has a height of 9 ft and a horizontal run of 7.

We know that slope of a line represents the relation between rise over run. The run is the horizontal distance between to x-coordinates and rise is vertical distance between two y-coordinates.

\text{Slope}=\frac{\text{Rise}}{\text{Run}}  

\text{Slope}=\frac{9}{7}  

Therefore, the pitch of roof is \frac{9}{7} and option D is the correct choice.

Can anyone help me with this question please

Answer:

  7.  ∠CBD = 100°

  8.  ∠CBD = ∠BCE = 100°; ∠CED = ∠BDE = 80°

Step-by-step explanation:

7. We presume the angles at A are congruent, so that each is 180°/9 = 20°.

Then the congruent base angles of isosceles triangle ABC will be ...

  ∠B = ∠C = (180° -20°)/2 = 80°

The angle of interest, ∠CBD is the supplement of ∠ABC, so is ...

  ∠CBD = 180° -80°

  ∠CBD = 100°

__

8. In the isosceles trapezoid, base angles are congruent, and angles on the same end are supplementary:

  ∠CBD = ∠BCE = 100°

  ∠CED = ∠BDE = 80°

Answer:

7x + 14

Step-by-step explanation:

the first thing to do is expand the parentheses/brackets.

3(5x + 2) -2(4x - 4) will be

3(5x) + 3(2) -2(4x) -2(-4)

= 15x + 6 - 8x + 8

collect like terms

15x - 8x + 6 + 8 = 7x + 14

the answer is 7x + 14
