Answer:

10 square units.

Step-by-step explanation:

Remark

No matter how weird it looks, the figure is a trapezoid. It has 2 parallel lines.

The height has 2 right angles, one at each end.

Givens

b1 = 2

b2 = 8

h = 2

Formula

Area = 1/2 * (b1 + b2 ) * h

Solution

Area = 1/2 * (2 + 4 + 2 + 2) * 2 Be sure you understand where all those 2s came from.

Area = 10 square units

Work out Ryan’s average speed for his total return journey detailing how you worked it out.

pickupchik [31]

Answer:

For the return, i guess that you say in the interval between 15:40 and 15:45, that is the moment where he goes back to his home, and pass through the local shop.

Ok, in the graph we can see pairs (time, position)

The average speed can be obtained with two of these pairs, and the average speed is:

As = (position2 - position1)/(time2 - time1)

In this particular case, we have the pairs:

(15:40, 900m) and (15:45, 400m)

(i guess that the distance is in meters)

Then the average speed is:

As = (900m - 400m)/(15:45 - 15:40)

and 15:45 - 15:40 = 0.5 minutes.

As= 500m/5 min = 100 m/min

This means that the average speed in this return is 100 meters per minute

Which equation represents a proportional relationship?

Verizon [17]

y = 3 x equation represents a proportional relationship.

Answer: Option B

<u>Step-by-step explanation:</u>

A proportional variation represents a relationship between two variables x and y. It can be expressed in the form y=k x. Here, the ‘k’, the proportionality constant is equal to the slope m and the line goes through the origin

case A) $y=2\left(x+\frac{1}{3}\right)$

A linear equation that not passes through the origin and so not proportional variation

case B) y= 3 x

Is a linear equation but passes through the origin and so proportional variation

case C) y = - 3x+2

A linear equation that not passes through the origin and so not proportional variation

case D) $\text { D) } y=\frac{1}{2 x}$

An inverse variation equation but not passes through the origin and so not proportional variation.

From these, equation option B is the proportion equation because in these equations, there is no addition and subtraction of any constant number. That’s why both these equations become proportional equations.
