You can use a plot diagram to plot the points and if they all go straight through the origin then it is proportional :)

On a bicycle, Esmeralda rides for 2 hours and is 12 miles from her house. After riding for 9 hours, she is 47 miles away.
In-s [12.5K]

For this case what we must do is find the speed of Esmeralda.

For this, we look for the rate of  change of the function

We have then:

AVR=\frac{y2-y1}{x2-x1}

Substituting values:

AVR=\frac{47-12}{9-2}

Rewriting:

AVR=\frac{35}{7}

AVR = 5

Answer:

Esmeralda's average rate during her trip is 5 miles per hour.

Answer:

21mm

Step-by-step explanation:

The formula for solving the area of a rhombus is : \frac{1}{2}xy, where x and y are two intersecting diagonals.

In this case, we are given both values, thankfully. 6 and 7 are to be replaced with x & y. Now, the rest you have to do is simple math.

(6 * 7) / 2 = 21

The area of the rhombus is 21mm.

What is the remainder of 67 divided by 3?
hammer [34]
The remainder for 67 divided by 3 would be 1 because (this might be a bad explanation since i'm not good at explaining math without showing u my work) if u do divide 6 by 3, 3x2 is 6 and 6-6 is 0. Then if u divide 7 by 3, then 6 is the closest u can get to 7 without multiplying by a decimal. Then if u do 7-6, u get 1 and u cant divide 1 by 3 so the remainder would be 1.
