Answer 1
Answer:

Answer:

3. There were 5 footballs sold for every 2 basketballs.

Step-by-step explanation:

Let the number of basketball = x and the number of football = y.

It is given that, 'the number of footballs were 2.5 times the number of basketballs last year'.

That is, y= 2.5x

That is, (y)/(x)=(2.5)/(1)

That is, (y)/(x)=(5)/(2)

That is, the ratio of football to basket ball is 5 : 2.

Which means, 'For every 2 basketballs, 5 footballs were sold'.

So, option 3 is true but options 1 and 4 are not true.

Moreover, 'if there were total 35 balls sold', we have,

x+y=35

i.e. x+2.5x=35

i.e. 3.5x=35

i.e. x= 10

So, y= 2.5x implies y= 2.5* 10 i.e. y= 25.

Thus, for total 35 balls sold, 10 were basketballs and 25 were footballs.

So, option 2 is not true.

Hence, the correct answer is option D.

Well, we can really show our work because their is no work to be done. Question 7 is a right angle because it is exactly 90 degrees. So since you now know what a right angle is, you can probably guess Question 8 a would be either 3 o'clock or 9 o'clock. For question 8b , he first one, and acute angle is an angle where it is below 90 degrees. So an example of an acute time is 3:05. An obtuse angle is an angle above 90 degrees. So an obtuse time would be (for example) 3:55. Hope this helped.
