Speed=distance/time
speed=37.5/3
=12.5 m/s
Answer:
1
Step-by-step explanation:
The slope of this line is -1 or -1/1, and to find the perpendicular slope you find the opposite of the reciprocal, which in this case would be 1/1 which simplifies to 1.
Answer:
a = -12
Remember that when a variable is times with a number, you <u>divide</u> the number on both sides.
When a variable is divided by a number, you <u>multiply</u> the number on both sides.
Hope this helps you. Thank you !!
Answer:
Sabemos que:
L es el largo de la avenida.
En la primer etapa se asfalto la mitad, L/2, entonces lo que queda por asfaltar es:
L - L/2 = L/2.
En la segunda etapa se asfalto la quinta parte, L/5, entonces lo que queda por asfaltar es:
L/2 - L/5 = 5*L/10 - 2*L/10 = (3/10)*L
En la tercer etapa se asfalto la cuarta parte del total, L/4, entonces lo que queda por asfaltar es:
(3/10)*L - L/4 = 12*L/40 - 10L/40 = (2/40)*L
Y sabemos que este ultimo pedazo que queda por asfaltar es de 200m:
(2/40)*L = 200m
L = 200m*(40/2) = 4,000m
Answer:
1. all real numbers less than or equal to 4 = </= 4.
Answer = YES!
2. all real numbers less than or equal to -3 = </= -3.
Answer = YES!
3. all real numbers greater than or equal to 4 = >/= 4
Answer = YES!
4. all real numbers greater than or equal to -3 = >/= -3
Answer = NO!
Step-by-step explanation:
1. all real numbers less than or equal to 4 = </= 4.
1 + 1 = 2
1 + 2 = 3
2 + 2 = 4
2. all real numbers less than or equal to -3 = </= -3.
1 - 1 = 0
1 - 2 = -1
1 - 3 = -2
1 - 4 = -3
3. all real numbers greater than or equal to 4
1 + 1 = 2
1 + 2 = 3
1 + 3 = 4
1 + 4 = 5
4. all real numbers greater than or equal to -3
1 - 1 = 0
1 - 2 = -1
1 - 3 = -2
1 - 4 = -3
