mylen [45]

Answer:

0.81

Step-by-step explanation:

The letters between L and P are M,N,O.

It is inclusive, so we have 5 letters L,M,N,O,P.

The letters which we can choose we have 26-5=21.

The probability to choose a letter not between L and P is 21/26=0.81

The solution is 0.81, ie,

You have 81% chance to choose latter not between L and P.

Determine the equation of the circle graphed below
Irina-Kira [14]

Answer:

(x-1)^2+(y-6)^2=16

Step-by-step explanation:

The equation of a circle is given by (x-h)^2+(y-k)^2=r^2, where (h,k) is the center of the circle and r is the radius of the circle.

From the diagram, we can find the following:

  • the radius of the circle is 4
  • the center of the circle is located at (1,6)

Thus, we have:

(x-1)^2+(y-6)^2=4^2,\\\boxed{(x-1)^2+(y-6)^2=16}

The measures of two angles are 4x and (2x+12). what is the measurement of each angle if x=13?
oksano4ka [1.4K]

Answer:

52 and  38

Step-by-step explanation:

If x = 13 then 4x = 4 * 13 so 52.  

Same for the next one.  2x = 2 * 13 so 26.  26+12 is 38.  

Done...

Bonjour je suis en 3 ème pouvez vous m'aider s'il vous plaît une voiture met 2 h 30 pour faire 200 km 1. Calculer sa vitesse moy
Lemur [1.5K]

Répondre:

Explication étape par étape:

Vitesse = Distance / Temps

Distance donnée = 200 km

Durée = 2 h 30

Convertir le temps en heures

Depuis 60 minutes = 1h

2 heures 30 minutes = 2+ (30/60)

2h30 = 2 + 1/2 hors

2 heures 30 minutes = 2,5 heures

Vitesse en km / h = 200 km / 2,5 h

Vitesse en km / h = 80 km / h

D'où sa vitesse moyenne en km / h est de 80 km / h

a) Distance = Vitesse * Temps

Vitesse donnée = 80 km / h

Durée = 3h15

Temps = 3 15/60 h

Durée = 3,25 h

Distance = 80 * 3,25

Distance parcourue en 3h15 = 260 km

b) Distance = Vitesse * Temps

Vitesse donnée = 80 km / h

Durée = 42 minutes

Durée = 42/60 h

Distance = 80 * 42/60

Distance = 3360/60

Distance = 56 km

Distance parcourue en 42 minutes = 56 km

c) Distance = Vitesse * Temps

Vitesse donnée = 80 km / h

Durée = 3 h 36 minutes

Temps = 3 36/60 h

Durée = 3,6 h

Distance = 80 * 3,6

Distance = 288 km

Distance parcourue en 3 h 36 min = 288 km

d) Distance donnée = 540 km

Vitesse = 80 km / h

Temps = Distance / Vitesse

Heure = 540/80

Temps = 6,75 heures

Par conséquent, le temps nécessaire pour parcourir 540 km est de 6,75 heures
