Tomas is planning out a rail trail using a map with a marked grid. The head of the trail, which has an information kiosk, is loc

ated at (3, 0). He moves 1 unit east and 3 units north and places a pin at (4, 3) to represent the location of another information kiosk. He continues placing pins so that each pin is 1 unit east and 3 units north in relation to the previous pin. The map extends 30 units east and 40 units north to represent the land available for the rail trail to use. Where will the foot of the trail be if it also has an information kiosk and Tomas wants to make the trail as long as possible? Enter the coordinates in the boxes.

<span>Kiosks only occur when the y-coordinate is a multiple of 3. The closest to the 40 units of northern land would be at 39. 39 divided by 3 would mean Tomas placed an additional 13 kiosks after the first. With the x-coordinate incrementing 1 unit east each time, the x-coordinate of the last kiosk endpoint is 3+13 or 16. Thus the foot of the trail ends at (16,39).</span>

Since the head of the trail is located at (3, 0), the trail moves 3 units north with each move and the map extends to 40 units to the north, then the number of 3 units in 40 units is 13. 

Thus, he can move only thirteen 3 units to the north and hence, thirteen 1 unit to the east.

Thus, the x-coordinate of the foot of the trail is 3 + 13 = 16 and the y-coordinate of the foot of the trail is 0 + 3(13) = 39.

Therefore, the location of the foot of the trail is at (16, 39).

6 more than 5 times a number (x) is at least twenty- one
VMariaS [17]
Okay, so to start you off, try to write an equation, like 5x+6=21. Then, subtract the 6 to both sides of the equal sign. This gets you 5x=15. At this point, divide the five on both sides. This will then get you x=3. I hope that that was what you were looking for. Have a great day!!!!!

If the ordinate is three more than twice the abscissa and x ∈ {-1, 0, -1/3}, which of the following sets of ordered pairs satisf
Zigmanuir [339]
Y = 2 x + 3
We will plug in the numbers from the sets:
1 = 2 · ( -1 ) + 3 = - 2 + 3= 1  ( correct )
3 = 2 · 0 + 3 = 0 + 3= 3          ( correct )
7/3 = 2 · (-1/3 ) + 3 = -2/3 + 3 = - 2/3 + 9 /3 = 7/3   ( correct ) 
Answer : A ) { (-1, 1 ), ( 0, 3 ) , ( -1/3, 7/3 ) }

Find the volume of a ball with radius 6 inches. Use the formula V=4/3 3.14r^3. Round to the nearest whole number
konstantin123 [22]
Answer: 904 inches cubed

Explanation:
Since you know that the radius is 6 inches, then all you have to do is plug it into the formula.
V=(4/3)*(3.14)*(6)^3
=(4/3)*(3.14)*(216)
=904.32
When you round that to the nearest whole number, it becomes 904.
