Answer: 2.5, 5.4
Step-by-step explanation:

Answer:
2, 1, 1/2, 1/4
Step-by-step explanation:
2¹ = 2
2^0 = 1
2^-¹
= 1/2¹
= 1/2
2^-2
= 1/2²
= 1/2*2
= 1/4
To complete the table
2² 2¹ 2^0 2^-1 2^-2
4 2 1 1/2 1/4
Answer:
0
Step-by-step explanation:
-3y(2y+5)=0
-6y+15y=0
9y=0
y=0÷9
y=0
I do not agree because 3/4 is greater than 2/3 so you can not do 3/4-2/3
The relationship between space, time and velocity for a uniform motion is given by:

where
S is the distance covered
t is the time
v is the velocity
The plane in our problem has a velocity of

and so during a total time of t=4 h, the distance it covers is

therefore, 680 miles.
