Answer:
initial speed: 240 m/h
Step-by-step explanation:
48 m/h is the current speed which is the 20% of X
x (20 / 100) = 48
20x = 4800
x = 4800/20
x = 240 m/h
The two inequalities are :
option B and option C
Explanation:
Daniel moves no more than 30 of his sheep and goats into another field. This means the summation of sheep and goats will be at maximum 30.
that is why it is 
And more than 7 of his animals are sheep means sheep are greater than 7. that is why = 
First you take a protractor and a pencil
next, you draw a horizontal line (red)
then find the value of the angle, and draw a line with the matched value (green)

Answer:
1444.4 m2
Step-by-step explanation:
Surface Area = 2 * 3.14 * (R*R + R*L) = 2 * 3.14 * (10*10+10*13) = 1444.4 m2
Note .. You can Derive this
"Surface Area = 2 * 3.14 * (R*R + R*L)"
Using Calculus by differentiating its Volume
V = 3.14 * R * R * L
