1. 12 km/hr

2. a - 36   b - 40%

3.  a - 8 vertices  b - 27ft^3

Step-by-step explanation:

1. If Pedro was going 96km/8hrs, then division is all that is needed in order to determine how many kilometers per 1 hour that Pedro is going.

Just divide 96/8  

2. First understand that three-fifths is like saying 3/5.

a. When converting percents 3/5 is equal to 60%

Therefore in a when asking how many of the baker's cookies were chocolate it is 60% of them. So you take 60% move the decimal to the left 2 spaces to make .60 and multiply that by 60

.60 x 60

That gives you 36.

b. So if we know that 3/5 is 60% then we know that the remaining percent is 2/5 or 40%.

Therefore that is the remaining cookies that were not chocolate in the batch

3. First understand what a vertice is

a. Vertice - A point or corner where 2 or more line seqments meet.

when looking at the cube it is representative that there are 8 because each corner has multiple sides connecting to each other

therefore just count the corners in this situation.

b. the equation for volume is:

length x width x height

Each side is equal to 3

Therefore to solve the equation it is:

3 x 3 x 3

= 27

then make sure to add the ft^3 because that is always required in any measurement of a 3d Shape.  

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
