They meet (or pass) each other two hours after B leaves.
When B starts trip A has already gone 23 miles (46 x 0.5)
This means they are still 220 miles apart.
Their closing speed is 46 + 64 = 110 mph.
They will meet 2 hours after B leaves home. (220 / 110)
A will have travelled 46 x 2.5 = 115 miles and B will have travelled 2 x 64 = 128 miles
Answer:

Step-by-step explanation:
Assuming the geometric series is

then nth term is
,
and the first term is found when
:

There are two acceptable ways of solving this. I'll show both (just in case one of them doesn't align with the information from your textbook).
Option 1 (fast and easy):The following is the equation for the area of a regular pentagon with side length s.

Plug s=12 into the equation.


The third choice should be your answer.
Option 2 (much more complicated):The area of a regular polygon can be solved with the following formula.

Let's solve for the apothem.
A pentagon can be divided into 5 congruent isosceles triangles. The vertex angle will be 360/5, or 72 degrees.
An isosceles triangle can be divided into two right triangles. One of the angles of the right triangle will be 72/2, or 36 degrees.
The leg opposite of the 36 degree angle will be 12/2, or 6 inches long.


The apothem is about 8.26 inches.
The perimeter is 12*5, or 60 inches.



(it seems that we're off by 0.1 due to rounding errors)
The answer is the third choice. Hope this helps! :)
Answer:
y = -2x + 5
Step-by-step explanation:
The y intercept is the point where the line meets the y axis, and it meets at 5.
The slope is -2/1, because it goes down 2 and over 1.
Answer:
D.
Step-by-step explanation:
If you look at the pattern, the first shape (square) has four sides. Then, you have 5 sides, and finally, 6 sides.
Thus, a pattern of 4, 5, 6. So, the next shape must have 7 sides, leaving the only possible answer as D.
