What is the median of 1.5 hours 30 minutes 1 hour 15 minutes and 1.25 minutes

1 answer:

5 0

We have 1.5 hours 30 minutes = 120 minutes;
1 hour 15 minutes = 75 minutes;
1.25 minutes = 85 minutes;

75 < 85 < 120
The median is 85 minutes.
Finally, 1 hour 15 minutes is the median.

$y = - 3x^{2} + 18x + 10 \\ \frac{d}{dx}( - 3x^{2} + 18x + 10) \\ - 6x + 18 = 0 \\ - 6x = - 18 \\ x = 3$

The axis of symmetry for parabola is x = 3.

Using derivative to solve for axis od symmetry is easier.

three bags of sweets weigh 27/4 kg. two of them have the same weight and the third bag is heavier than each of the bags of equal

Nana76 [90]

I'm here buddy,

so, let's take the value of the two bags with equal weight as x.

= x + x + (x + $\frac{6}{5}$ ) = $\frac{27}{4}$

= 3x + $\frac{6}{5}$ = $\frac{27}{4}$

= 3x = $\frac{27}{4}$ - $\frac{6}{5}$

( let's take the LCM of 4 and 5 = 20

= 3x = $\frac{135}{20}$ - $\frac{24}{20}$

= 3x = $\frac{111}{20}$

= x = $\frac{111}{20}$ ÷ $\frac{3}{1}$ = $\frac{111}{20}$ × $\frac{1}{3}$ = $\frac{37}{20}$

So, the weight of the equal bags are $\frac{37}{20}$ and the weight of the third bag ( heavy one ) is $\frac{37}{20}$ + $\frac{6}{5}$ = $\frac{37}{20}$ + $\frac{24}{20}$ = $\frac{61}{20}$

1st bag = $\frac{37}{20}$ kg

2nd bag = $\frac{37}{20}$ kg

3rd bag = $\frac{61}{20}$ kg

Hope it helps...
