Answer:

500 km

Step-by-step explanation:

The relationship between distance, speed, and time is ...

distance = speed × time

The units of speed and time must be compatible. Since we're given the rate in distance per hour, our time units must also be hours.

40 min = (40 min)(1 hour)/(60 min) = (40/60) hour = 2/3 hour

Then the distance the plane travels is ...

distance = (750 km/h)(2/3 h) = 500 km

The aeroplane travels 500 km in 40 min.

Answer:

500 km/40 min

750/60=12.5 12.5*40=500

Es posible dibujar 9 segmentos de línea de manera que cada segmento interseque exactamente 1 de los otros segmentos?

uysha [10]

Answer: No es posible (It is not possible)

Step-by-step explanation:

The question in english is as follows:

Is it possible to draw 9 line segments so that each segment crosses exactly 1 of the other segments?

A necessary condition for two lines to intersect is that they must be in the same plane (they must be coplanar), being their intersection a single point.

Now, if we want several lines to intersect only once, we need to have an <u>even number</u> of line segments. However, this is not the case because <u>9 is odd. </u>

Therefore, it is not possible.

Log1/2 28? What is it?

I am Lyosha [343]

$\log_a(b\cdot c)=\log_ab+\log_ac\\\\\log_ab^c=c\cdot\log_ab\\\\\log_aa=1\\--------------------\\\log_\frac{1}{2}28=\log_\frac{1}{2}(4\cdot7)=\log_\frac{1}{2}4+\log_\frac{1}{2}7=\log_\frac{1}{2}2^2+\log_\frac{1}{2}7\\\\=2\log_\frac{1}{2}2+\log_\frac{1}{2}7=\boxed{2+\log_\frac{1}{2}7}$

$\log_ab=\frac{\log_cb}{\log_ca}\\-------------------------\\\log_\frac{1}{2}7=\frac{\log\frac{1}{2}}{\log7}\approx\frac{-0.6931}{1.9459}\approx-0.3562\\\\therefore\\\\\boxed{\log_\frac{1}{2}28\approx2+(-0.3562)=1.6438}$
