Four runners start at the same point: Lin, Elena, Diego, Andre. For each runner write a multiplication equation that describes t

heir journey.
I NEED A REAL ANSWER!! NOT "I DON'T KNOW!!" IF YOU DON"T KNOW, DON'T ANSWER!!!

Lin runs for 25 seconds at 8.2 meters per second. What is her finish point?
Elena runs for 28 seconds and finishes at 250 meters. What is her velocity?
Diego runs for 32 seconds at -8.1 meters per second. What is his finish point?
Andre runs for 35 seconds and finishes at -285 meters. What is his velocity?

Mark the formulas

  • Velocity=Displacement/Time

#Lin

We need distance

\\ \tt\hookrightarrow 25(8.2)=205m

#Elena

We need velocity

\\ \tt\hookrightarrow 250/28\approx 9m/s

#Diego

We nend distance

\\ \tt\hookrightarrow 32(-8.1)=-259.2m

#Andre

We need velocity

\\ \tt\hookrightarrow -285/35\approx -8m/s

Answer:

Lin =    8.2 m/s  x  25 s =<u> 205 m  </u> (<em>Finish Point)</em>

Elena =  V = 250 m / 28 s     <u>V = 8.93/s </u> (<em>Velocity</em>)

Diego = -8.1 m/s x 32 s =<u> -259.2 meters</u>  (<em>Finish Point</em>)

Andre =  V = -285 m /35 s     V= -8.14ms  (<em>Velocity</em>)

The equations -6x + 3y = 6 and x² + y = 10 intersect at the
eimsori [14]

The values of the letters in coordinates (a, b) and (c,d) are;

<u><em>a = -4</em></u>

<u><em>b = -6</em></u>

<u><em>c = 2</em></u>

<u><em>d = 6</em></u>

<u><em /></u>

We are given two equations;

-6x + 3y = 6  ---(eq 1)

x² + y = 10 ---(eq 2)

  • We are told that they intersect at coordinates; (a, b) and (c, d).

Let us make y the subject in eq 2 to get;

y = 10 - x²  --(eq 3)

  • Let us put 10 - x² into eq 1 to get;

-6x + 3(10 - x²) = 6

expanding further gives;

-6x + 30 - 3x² = 6

rearranging gives;

3x² + 6x - 24 = 0

Using online quadratic equation <em>solver</em>, we have;

x = -4 and x = 2

Putting x = -4 into eq 3 gives;

y = 10 - (-4)²

y = 10 - 16

y = -6

Putting x = 2 into eq 3 gives;

y = 10 - (2)²

y = 10 - 4

y = 6

  • Thus, the coordinates are; (-4, -6) and (2, 6)

Comparing with (a, b) and (c,d), we have;

a = -4

b = -6

c = 2

d = 6

A school principal wants to find out if his school needs more bike racks. a survey is taken of 30 students who ride their bikes
Sergio039 [100]
Hello there.

Question: <span>A school principal wants to find out if his school needs more bike racks. a survey is taken of 30 students who ride their bikes to school. why might the sample be biased?

Answer: It might be biased as the survey was only taken of students who ride their bikes to school. It is most likely that they would agree to it. To make it fair they survey should have been taken of a variety of different students.

Hope This Helps You!
