Set it up as a proportion
115/5=n/15
And then you cross multiply
5•n=15•115
5n=1725
n=345 miles
Answer:
Distributive Property
Step-by-step explanation:
Using function concepts, it is found that the turning points of the graph are:
- November 2000, when it goes from increasing to decreasing.
- December 2000, when it goes from decreasing to increasing.
- June 2001, when it goes from increasing to decreasing.
In a graph:
- A function is increasing if it is <u>pointing upwards.</u>
- If it is <u>pointing downwards,</u> it is decreasing.
- A turning point is when the function changes from <u>decreasing to increasing or vice-versa</u>.
In this problem:
- Initially, the function is increasing.
- In month 3, that is, November 2000, it starts to decrease, thus, in November 2000, we have a<u> turning point.</u>
- The next month, that is, December 2000, it starts to increase again, so it is another <u>turning point</u>.
- It increases until month 9, which is June 2001, when it starts to decrease, being the <u>final turning point.</u>

Answer:
m<C = 66°
Step-by-step explanation:
Perpendicular bisector, AB divides angle CAD into two equal parts. Therefore:
(5x + 9)° = (7x + 3)°
Solve for x
5x + 9 = 7x + 3
Collect like terms
5x - 7x = -9 + 3
-2x = -6
Divide both sides by -2
x = 3
✔️m<C + m<CBA + m<BAC = 180° (sum of triangle)
m<C + 90° + (7x + 3)° = 180 (substitution)
Plug in the value of x and solve
m<C + 90 + 7(3) + 3 = 180
m<C + 90 + 21 + 3 = 180
m<C + 114 = 180
m<C = 180 - 114 (Subtraction property of equality)
m<C = 66°
