Answer:
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.
