There are 56 students in a school play. The ratio of boys to girls is 3:5. How many girls are in the school play?
Murrr4er [49]

Answer:

35 girls

Step-by-step explanation:

First add the ratios together ( 3+5) this will give you 8. Then divide the total number of students by 8, this will get you 7. Now multiply 7 to 3 and multiply 7 to 5. As the ratio of boy to girl is 3 to 5, to find how many girls are in the school play we multiply 7 to 5. This makes 35 girls.

If you want to check, 7 x 3 =21 boys and 7 x 5=35 girls. 35 +21= 56 (the total number of students).

Graph the relation and it's inverse. Use open circles to graph the points of the inverse
joja [24]

Step-by-step explanation:

We are given a set of points (0,3), (4,2), (9,7) and (10,-1) representing a function.

It is required to graph the function and its inverse.

As we know that, the inverse of a function is reflected by y=x line on the graph.

So, in order to find the inverse we have to replace the co-ordinate (x,y) by (y,x).

Then the points (3,0), (2,4), (7,9) and (-1,10) represents the inverse of the function.

So, after plotting all the points of the function and its inverse, we get the following graph, where figure 1 is of the function and figure 2 is of its inverse.
