Paulo has 39 patches from states he and his relatives have visited he wants to pin the onto a board and arrange them equally in 3 rows how many patches will be in each row

Answers

Given:

Total number of patches = 39

Total number of rows = 3

To find:

The number of patches in each row.

Solution:

We have,

Total number of patches = 39

Total number of rows = 3

We need to divide the total number of patches by total number of rows to find the number of patches in each row.

\text{Number of patches in each row}=(39)/(3)

\text{Number of patches in each row}=13

Therefore, the number of patches in each row is 13.

Austin plays both forward and goalie on the school soccer team. He has played forward in 4 games for every 3 games he has been the goalie this season. Pick the diagram that models the ratio in the story. If Austin has played forward in 8 games, in how many games has he been the goalie?

Answers

Answer:

Austin has been the goalie in 6 games.

Step-by-step explanation:

The diagram that models the ratio in the story is a fraction diagram.

Let's represent Austin playing forward as F and Austin being the goalie as G.

According to the story, Austin has played forward in 4 games for every 3 games he has been the goalie. This can be represented as the fraction 4/3.

Now, we know that Austin has played forward in 8 games.

To find out how many games he has been the goalie, we can set up a proportion using the ratio from the story:

4/3 = 8/x

To solve for x, we can cross-multiply:

4x = 3 * 8

4x = 24

Dividing both sides of the equation by 4, we get:

x = 6

Therefore, Austin has been the goalie in 6 games

Miguel is making an obstacle course for field day. At the end every sixth of the course,there is a tire. at the end of every third of the course ,there is a cone. At the end of half of the course,there is a hurdle. At which locations of the course will people need to go through more than one obstacle

Answers

People will need to go through more than one obstacle at three places in the course:  The 1/3 mark, the 1/2 mark, and the 2/3 mark.

The tires are at these spots
--\--\--\--\--\--\

The cones are at these spots
----\----\----\

And the hurdles are here:
------\------\

When you combine these:
--\--\\--\\--\\--\--\\\

You get two marks at the 1/3, 1/2, 2/3, and Final spots (Final can be 1, 2/2, 3/3, or 6/6.)
the people will have to go through these obstacles more than once:
The tires are here
--\--\--\--\--\--
The cones are here
---\---\---
but this would be the hurdle which is at the end of half the course
----\----
only one spot so it would only be the first two cuz they are repeated
