Assuming that the actual question reads lines b and c are perpendicular to line d
we are given that c is perpendicular to line d and parallel to line a. Since b is also perpendicular to line d, a b and c must all be parallel (draw it out will make a lot more sense)
So b is also parallel to line a
Answer:
C and D
Step-by-step explanation:
You multiply the first two numbers and add the exponents of the second two while keeping the base number. I'm 99.9% sure. I hope this helps!
1 is in the one-tenths place. If 2 was in this spot, it would be two-tenths.
Here are the place values for the question's given number of 56.123.
5- tens
6- ones
decimal
1- tenths
2- hundredths
3- thousandths
ANSWER:
1 has the place value of C) one-tenth

Answer:
6 PM
Step-by-step explanation:
The truck has a 2 hour head start. It is moving at 45 km/h, so it is 90 km ahead.
If t is the time after 8 AM, then the distance between the truck and the station is:
d = 90 + 45t
The distance between the van and the station is:
d = 54t
When the distances are equal:
54t = 90 + 45t
9t = 90
t = 10
It takes 10 hours after 8 AM for the van to catch up with the truck. So the time would be 6 PM.
Veremos que la velocidad inicial es:
V = -a*t + Vo
<h3>
¿Como obtener la velocidad inicial?</h3>
Cuando tenemos la ecuación de la aceleración a(t), la velocidad inicial es el termino que se resta, de tal forma que deberiamos tener:
a = (velocidad final - velocidad inicial)/tiempo.
En este caso, la fórmula de aceleracion es algo como:
a = (Vo - V)/t
El termino que se resta es V, entonces esa es la velocidad inicial, para despejarla multiplicamos por t ambos lados y restamos Vo en ambos lados:
a*t - Vo = -V
Ahora multiplicamos por -1 a ambos lados:
-a*t + Vo = V
Esa es la velocidad inicial.
