Answer:

410 miles

Step-by-step explanation:

total distance covered (d) = 1640 miles

total time taken (t) = 4 hrs

average distance per hour= d/t

= 1640/4

= 410 miles

NUMBER 6 PLEASE HELP ASAP
Aleksandr [31]

Answer:

Part A: 115

Part B: 36000

Explanation:

Part A asks for the perimeter, which is adding, so add up the 15, 40, and 60, which will equal to 115.

Part B asks for the area, which is multiplying, so you multiply the numbers,

15 x 40 x 60 = <u>36000</u>

15 x 40 = 600

600 x 60 = 36000

You could try multiplying it a different way but get the same answer:

60 x 40 x 15 = <u>36000</u>

60 x 40 = 2400

2400 x 15 = 36000

I'm not sure if this is correct but I hope I helped

have a great day/night :))

Table:
Fynjy0 [20]

Answer:

2) Yes, each x-coordinate is only used once.

3) {1,2,3,4}

4) {25,45,60,70}

5) (3,60)

6) No because (4,7) and (4,25) share the same x-coordinate.

Step-by-step explanation:

A relation is a function if there is no more than one y-value assigned to an x.

Any x used can only be used once in an order pair.

You that here.

(1,25)

(2,45)

(3,60)

(4,70)

So basically because all of the x-coordinates are different, this is a function.

The domain is the x-coordinate of each pair (the first of each pair):

{1,2,3,4}.

The range is the y-coordinate of each pair (the second number of each pair):

{25,45,60,70}.

One ordered pair that I see in the table is (3,60). There are 3 others you can choose and I named them above.

{(4,10),(3,15),(1,5),(2,25),(4,25)} is not a function because there are more than one pairs with the same x-coordinate,4.
