Answer:

19.8 minutes

Step-by-step explanation:

Total time the 4 laps was completed = 4 x 2.5 = 10 minutes

Total time the 2 laps was completed = 2 x 4.9 = 9.8 minutes

total time = 10 minutes + 9.8 minutes = 19.8 minutes

Pls help asap...urgently help needed!!!<br>tia

Answer:

(a) v =  1536640/ m^2.

(b)  (i)   1186 m/s.

     (ii)   52.4g .

Step-by-step explanation:

(a)   The equation is v = k / m^2     where k is the constant of variation.

When m = 49, v = 640 so   640 = k / 49^2

k = 640 * 49^2

= 1,536,640.

Therefore the relation is v =  1536640/ m^2.

(b) (i)

When m = 36g,  the speed v = 1536640 / 36^2

= 1186 m/s.

(ii)   When the speed is  560 m/s :-

560 = 1536640 / m^2

m^2 = 1536640 / 560

=  2744

mass m = √2744

=  52.4g

Which expressions are equivalent to 1/2+3c+4/5
Nitella [24]

The equivalent expression of 1/2 + 3c + 4/5 is \frac{13 + 15c}{10}

<h3 /><h3>How to determine the equivalent expression?</h3>

The expression is given as:

1/2 + 3c + 4/5

Take the LCM of the expression

\frac{5 + 15c + 8}{10}

Evaluate the like terms

\frac{13 + 15c}{10}

Hence, the equivalent expression of 1/2 + 3c + 4/5 is \frac{13 + 15c}{10}
