Not evenly, no. If you divide 4460 by 3 or 9, the answer comes out as a decimal

In the relationship shown by the data linear ? If so , model the data with an equation A. The relationship is not linear B. The

dybincka [34]

Let's take two points so that we can get the equation of the line which goes through those points. P1 (-9, -2), P2 (3, -17):

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{-17-(-2)}{3-(-9)}=\frac{-17+2}{3+9}=-\frac{15}{12}=-\frac{5}{4}$ $\begin{gathered} y-y_1=m(x-x_1) \\ y-(-2)=-\frac{5}{4}\cdot(x-(-9)) \\ y+2=-\frac{5}{4}\cdot(x+9)_{} \\ y=-\frac{5}{4}x-\frac{45}{9}-2 \\ y=-\frac{5}{4}x-7 \\ f(x)=-\frac{5}{4}x-7 \end{gathered}$

So, y is the line which goes through the first and last points of the chart.

To proof that the rest of points go through the line as well, we will evalute each point

$\begin{gathered} f(-5)=-\frac{5}{4}\cdot(-5)-7=\frac{25}{4}-7=-\frac{3}{4}\ne-7 \\ f(-1)=-\frac{5}{4}(-1)-7=\frac{5}{4}-7=-\frac{23}{4}\ne-12 \end{gathered}$

Since the evaluation of these points don't correspond to the values of the chart we can assure that the relationship is not linear

Mark ran a mile in 7 1/2 minutes. His brother ran a mile in 6 1/6 minutes. How much more time does Mark take to run the mile?

Bas_tet [7]

Answer:

1 1/3 more minutes

Step-by-step explanation:

Lets first convert both times to improper fractions

7 1/2 -> 15/2 (Mark's Time)

6 1/6 -> 37/6 (Mark's Brother's Time)

Now we need common denominators

15/2 = 45/6

Now times to subtract Mark's time - Mark's Brother's Time = More Time

45/6 - 37/6 = 8/6 or 1 2/6 = 1 1/3

Seth measured a hotel and made a scale drawing the the scale he used was 1 inch : 3 feet the actual of the hotel is 18 feet how

sertanlavr [38]

Answer:

Step-by-step explanation:

Width of the room in the drawing = x

1 : 3 :: x : 18

Product of means = Product of extremes

3 * x = 18 *1

x = 18 ÷ 3

x = 6

Width of the room in the drawing = 6 inches
