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.
121 = 112 - k • -3
9 = k • -3
k = -3
Answer:
D
Step-by-step explanation:
4.2 precent of 5000 is 210. You multiply that by the year (4) because he paid 4.2 of 5000 anually. If you multiply that the answer should be 840.
3.9 precent of 5000 is 195. If you multiply that again by 6 (the year) because he paid 3.9 of 5000 anually. If you multiply that your answer should be 1170.
Now after all that subtract. 1170-840= 330
Answer and Step-by-step explanation: Suppose remaining credit is y and time in minutes is x. To determine a value of y corresponding to a value of x, first find the equation for the function.
Since the function is linear, the equation is of the form: y = mx + b. To determine it:
1) Find slope, or inclination, of the line:
slope (m) = 
where x's and y's are points of the function.
2) Determine the y-intercept, or b: Use a point of the function, replace them at the equation, y = mx + b, and find b.
3) The equation will be: y = mx + b
With the equation, replace x for the minutes the question is asking and calculate to find the remaining credit.
Th result will be a pair (x,y)
