Answer:

16m/s

Step-by-step explanation:

distance travelled from L to M = 6 x 10 = 60m

distance travelled from M to N = 160 - 60 = 100m

time taken to travel from M to N = 100/25 = 4 seconds

average speed = total distance / total time = 160m / (6 + 4) seconds = 16m/s

hope that helps!

this is a question on speed, distance and time. I have a formula for it up in my insta page (learntionary) if you need it :)

Answer:

This confusing

Step-by-step explanation:

So the answer could be 35m/s I think this because if M to N is 25m/s that means it closer and L to M is 10m/s that mean shorter which make L and N a longer distance

The surface area of this cube is 864 square yards. What is the value of q?
earnstyle [38]

Answer:

Volume  

=

512

cubic feet

Explanation:  

A cube has  

6

faces all with equal area.

If the total surface area of the cube is  

384

sq.ft.

then each face has an area of  

384

÷

6

=

64

sq.ft.

Each face of a cube is a square and if we denote the length of an edge as  

E

then the area of a face (in this case  

64

sq.ft.) is equal to  

E

2

XXX

E

2

=

64

sq.ft.

XXX

→

E

=

8

sq.ft.

The volume of a cube with edges of length  

E

is  

E

3

In this case  

Volume

=

E

3

=

8

3

=

512

sq.ft.

Hope i helped

Emily bikes 18 miles in 2 hours. Ella bikes 22 miles in 2.5 hours. Which rate is better?
DaniilM [7]
By better I am assuming you meant faster so,
18 ÷ 2 = 9
22 ÷ 2.5 = 8.8
9 > 8.8
therefore Emily has the faster rate.

A gravel company sells gravel by the cubic yard and charges a flat delivery fee. The table shows the total cost C based on the a
Sergio039 [100]

Answer:

<h2>$60.</h2>

Step-by-step explanation:

The cost for 0 cubic yards of gravel refers to the y-intercept of the function.

First, we find the constant ratio of change

r=\frac{284-124}{7-2}=\frac{160}{5}=32

The constant ratio of change is 32, that means the cost per cubic yard of gravel is $32.

Now, we just subtract this ratio twice to find the relations until we have x = 0.

124 -32= 92

So, for 1 cubic yard, the cost is $92.

92-32=60

For 0 cubic yards, the cost is $60, that's the y-intercept or the initial condition.

Therefore, the answer is $60.
