Answer:
9.4 units
Step-by-step explanation:
Step one:
given data'
We are given the coordinates
x1=4.2
x2=-5.2
y1=-2
y2=-2
Required
The distance between the points
Step two:
The expression for the distance is
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((-5.2-4.2)²+(-2+2)²)
d=√((-9.4)²
d= √88.36
d= 9.4 units
Answer:
-0.55n - 0.05
Step-by-step explanation:
You can start by distributing:
(0.25n - 0.3) - (0.8n - 0.25)
0.25n - 0.3 - 0.8n + 0.25
Then, you can combine like terms(0.25n & -0.8n; -0.3 & 0.25)
-0.55n - 0.05
Assume w is the width. the length is 3*2w
To fence the whole outside of farm, he needs:
2(w+6w)=14w meters
Also he needs one width and one length for the enclosed pens. Therefore, the total amount of fencing he would need:
14w+w+6w=21w meters
First, add hours until the difference is less than an hour. You can add 3 hours on to make it 9:32 p.m. Then, add minutes on until it's the exact time. from 9:32 to 9:48, you can add 16 minutes, so the total time in the movie was 3 hours, 16 minutes.
