Answer:
He is 5.6 km away
Step-by-step explanation:
he starts traveling away from base and is 8.3 km away to start with
then he turns west and travels 13.9 km away
what this mean is that you have to subtract the distance he turned from the distance he started off with
ex: 13.9 - 8.3 = 5.9
to get your answer of how far away he is from the base
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point form:
(0, -3)
Equation form:
x = 0
y = -3
You have to square it all up then add it up if you want you can use the calculator
Answer:
b= 10
Step-by-step explanation:
h=2b, (bh/2)=100, bh=100, b^2=100, b=10
Answer:
Perimeter = 4.71 ft
Explanation:
Diameter = 3 ft
Radius (r) = 3/2 = 1.5 ft
Since, the figure is a half circle, it's perimeter will be = 2π*r/2 = π*r
Thus, perimeter = π*(radius) = 3.14*1.5 = 4.71 ft
