The best estimate of the lateral area of the cube with edges that are 2.1 inches long is 4.2
Answer:
290/s
Step-by-step explanation:
Basically, the question is asking you to find:
290/s miles per hour
The only problem is translating words to math.
Hope this helps!
Distance ran by Tara = 1600 m
Time taken by Tara to ran 1600 m = 5 min 20 seconds
We have to calculate the speed.
Firstly, we will convert the unit of time in one unit.
Time = 5 min 20 seconds
= 5 min +
min (Because 1 min = 60 sec)
= 
=
=
min
Now we will use Distance speed formula which states,
Distance = speed
time
1600 m = speed

speed = 
Speed = 300 m/min
So, the speed of Tara was 300 meter/min.
Slope, m, is y2-y1 / x2-x1 or 7- -1 / 10-2, or 8/8, or 1
using the 1st point we get
y+1=x-2
using the second we get
y-7=x-10
both are correct
