Answer:

$\huge\boxed{\bf\:c = \frac{11}{4}}$

Step-by-step explanation:

$4c + 2c = 4c + \frac{11}{2}$

Cancel 4c on both the sides of the equation.

$2c = \frac{11}{2}$

Bring the 2 in the denominator of 11/2 to the left hand side of the equation.

$2*2c = 11\\4c = 11$

Bring 4 to the right hand side if the equation.

$\boxed{\bf\:c = \frac{11}{4}}$

HELP PLEASE!!!!!! Find the speed of an athlete who makes 4and3/4 laps in 3mins45 seconds on a 400m field in m/s

Rom4ik [11]

Given:

An athlete who makes $4\dfrac{3}{4}$ laps in 3 mins 45 seconds on a 400m field.

To find:

The speed of the athlete in m/s.

Solution:

We know that,

Distance covered in 1 lap = 400 m

Distance covered in $4\dfrac{3}{4}$ laps = $4\dfrac{3}{4}\times 400$ m

= $\dfrac{19}{4}\times 400$ m

= $1900$ m

We know that,

1 minute = 60 seconds

3 minutes = 180 seconds

3 minutes 45 second = 180 + 45 seconds

= 225 second

The speed of the athlete is:

$Speed=\dfrac{Distance}{Time}$

$Speed=\dfrac{1900}{225}$

$Speed\approx 8.44$

Therefore, the speed of the athlete is about 8.44 m/s.

I need help please.

We are trying to represent the change in position of a bird flying down 7 ft to the ground.

Often, for the y axis- up is positive and down is negative.

Change in position is displacement- how far it was from the starting point

( different from distance which is how far is traveled

ex. doubling back would have distance they traveled some distance while the displacement is 0 because they are back to where they started).

The bird is going down 7 ft from where it originally was, which can be represented by

Bird's displacement = -7 ft
