F(10)=300+35(10)
f(10)=300+350
650(10)=300+350
6500

3 Metres; because for each 100 centimetres there is one metre. With centi- being the prefix for 10^-2 in the metric system.

Consider the following pair of points.

dedylja [7]

Answer:

The answer is

<h2> $\sqrt{265} \: \: or \: \: 16.28 \: \: \: \: units$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3> $d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$ </h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(9,-8) and (-7,-5)

The distance between them is

$d = \sqrt{ ({9 + 7})^{2} + ({ - 8 + 5})^{2} } \\ = \sqrt{ {16}^{2} + ( { - 3})^{2} } \\ = \sqrt{256 + 9} \: \: \: \: \: \: \: \: \: \\ = \sqrt{265} \: \: \: \: \: \: \\ = 16.27882$

We have the final answer as

$\sqrt{265} \: \: or \: \: 16.28 \: \: \: \: units$

Hope this helps you

In 25 minutes, Jay can run 10 laps around the track. Write an equation to represent the relationship.

Inessa [10]

Answer:

The equation is $y=\frac{2}{5} x$ .

Step-by-step explanation:

Let $y$ represent the number of laps Jay run, and $x$ the number of minutes it takes him to run those laps.

We know that it it takes Jay 25 minutes to run 10 laps; therefore, the number of laps jay runs per minute is:

$\frac{10\:laps}{25\:minutes} =\frac{2}{5}\:laps/min$

So, if Jay runs for $x$ minutes, the number of laps $y$ he will run be:

$\boxed{y=\frac{2}{5}x}$
