Un triangolo rettangolo isoscele è metà quadrato. L'ipotenusa è la diagonale del quadrato, e i cateti sono i lati del quadrato.
Nei quadrati abbiamo
dove 
è la diagonale e 
è il lato. Usa le informazioni sopra che collegano la diagonale con l'ipotenusa e i cateti con i lati e potrai trovare i cateti, e quindi l'area.
To find the rate, you must divide the distance traveled by the time it took.
17.5 m is the distance while time it took was 5 seconds.
So,
17.5 ÷ 5 = 3.5 m/s
The rate of the anchor is 3.5 m/s
Note: I did not ignore the negative sign in the distance but rather acknowledged it as a magnitude. This meant that the anchor was dropping down instead of going up.
Answer: average speed of the train = 4,483.0 km/h
Step-by-step explanation:
Speed = Distance / Time
Distance = 66 km
Time = 15.47 cancelling 15, we have 60 sec added to 47 sec
<u> - 14.54</u>
= 14. 107 60 + 47
<u> - 14. 54</u>
<u> 53secs</u>
53secs to hours becomes =
60 secs = 1 min
60 min= i hour
therefore 53seconds =53/3600=0.0147222hours
Speed= 66/ 0.0147222= 4,483.025
Rounding to 1 dp becomes= 4,483.0 km/h
9514 1404 393
Answer:
77 purple counters
Step-by-step explanation:
There are a total of 5+7=12 ratio units, so each stands for 132/12 = 11 counters. The 7 ratio units representing the purple counters stand for ...
11 × 7 = 77 purple counters
7y 4x and 2x they all are paired with a variable
