Answer:
82.5 kilometers
Step-by-step explanation:
15×5.5= 82.5 kilometers
Step-by-step explanation:
I assume they intersect at a right angle (90°).
then the intersection is a rectangle with one side being 12 m, and the diagonal being 13 m long.
the diagonal is the Hypotenuse (baseline) of a right-angled triangle with the length and the width of the rectangle as legs.
so, by using Pythagoras we have
diagonal² = length² + width²
13² = 12² + width²
169 = 144 + width²
25 = width²
width = 5 m
so, Oakdale Avenue is 5 m wide.
Answer:
-5/2 or -2.5.
Step-by-step explanation:
The remainder theorem states that if the polynomial f(x) is divided by (x - a) then the remainder is f(a).
To find the remainder we put x = -3/2 ( by solving 2x + 3 = 0).
The remainder = 4(-3/2)^3 + 6(-3/2)^2 + 3(-3/2) + 2
= -27/2 + 27/2 - 9/2 + 2
= -9/2 + 4/2
= -5/2.
3 because if the number behind the decimal point is a 5 or above you round up.
