Answer:

$3c \div d$

If c = 2, then

$3(2) \div d$

If d=-3, then

$3(2) \div ( - 3)$

We now evaluate

$6 \div - 3$

$- 2$

The answer is -2

Answer:

O is the center of the circle with radius IE(=ID=EF)

Step-by-step explanation:

Join all 3 points D, E, F, forming the triangle DEF.

Let the midpoint of EF be M and the midpoint of ED be N. (first picture)

Join point I to E, D and F.

Since IN is both an altitude and median to triangle EID, then triangle EID is an isosceles triangle, and IE=ID

similarly, we see that IE=IF.

conclusion: IE=ID=EF.

The results of a swim Wet are shown. Who swam faster explain your reasoning

kolbaska11 [484]

Answer:

The Susana swam the fastest.

Step-by-step explanation:

Speed : It is defined as the distance traveled per unit time.

Formula used : $Speed = \frac{Distance}{Time}$

First we have to determine speed of the following persons.

For Tawni :

Distance = 50 m

Time = 40.8 s

1.225 m/s which is the speed of Tawni.

For Pepita :

Distance = 100 m

Time = 60.2 s

1.661 m/s which is the speed of Pepita

For Susana :

Distance = 200 m

Time = 112.4 s

1.779 m/s which is the speed of Susana

From this we conclude that, in this problem meter affects the response and the speed of Susana is more than the Pepita and Tawani.

Thus, Susana swam the fastest.
