Answer:

1. 5 hours

2. 4 hours

Reason:

Formula for speed is speed = \frac{distance}{time} , if you want to find time, then take distance / speed, which will equal to 100 / 20 = 5 hours, and the same with 2.

\\ \rm\hookrightarrow Speed=\dfrac{Distance}{Time}

\\ \rm\hookrightarrow Time=\dfrac{Distance}{Speed}

So

#1

\\ \rm\hookrightarrow Time=\dfrac{100}{20}=5h

#2

\\ \rm\hookrightarrow Time=\dfrac{180}{45}=4h

The answer to the question
djyliett [7]

Hey there!

Looking at the graph, we can see that the lengths of the two bases are 6 and 3. We can also see that the height is 6 as well.

The formula for the area of a trapezoid is shown below.

A=0.5h(a+b)

In the equation, h represents the height and a and b represent the two bases.

Let's plug our values into the equation.

A=0.5(6)(6+3)

A=3(9)

A=27

Therefore, our answers are below.

Bases: 3 and 6

Height: 6

Area: 27 square units

I hope this helps!

Answer:

D

Step-by-step explanation:

The contrapositive is where the variables are reversed and the positive/negatives are reversed. For example, the contrapositive of the statement "If it rained last night, the ground is wet" is "If the ground is not wet, it did not rain last night".

 Can someone solve then explain the process of solving this?

Answer:

58°

Step-by-step explanation:

<h3>Angle sum property of triangle:</h3>

  The sum of all angles of a triangle is 180°.

 x + 69 + 55 + x + 78 = 180

  x + x + 69 + 55 + 78 = 180

Combine like terms,

                   2x + 202 = 180

Subtract 202 from both sides,

                              2x = 180 - 202

                              2x = -22

Divide both sides by 2,

                                 x = -22/2

                                 x = -11

∠A = x + 69

     = -11 + 69

 \sf \boxed{\angle A= 58^\circ}
