Answer:

Step-by-step explanation:
The fact that the figure is a cube means all sides, faces, and corners are equal.



First of all you have to convert kg to grams
so there is 1 kg in 1000g
.4 kg is 400g
1000+400= 1400g
1400-650 = 750 kg
that's your final answer
Answer:
A: 71°
Explanation:
The interior angles of a triangle must always equal 180°.
We have two of the angles, and if we add them up and subtract it from 180°, we can get the missing angle.
49+60+x=180
Add 49 and 60
109+x=180
Isolate the x, so subtract 109 from 180
x=71°
Answer:


Step-by-step explanation:
we are given
speed =8 mph
time = 6 hours
so, we have

now, we can find distance
distance = (speed)*(time)


so, we have

so, our range for x and y can be
