Match the formula to the correct figure. What goes where? :D Will give out Brainliest Answer!!!
5/8+7/8
Answer:
B. y: y= -7, -2, 3, 8}
Step-by-step explanation:
There are 20 girls in the play.
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
Given that;
There are 32 students in a play.
And, The ratio of girls to all students on the play is 5 : 8.
Now,
Since, The ratio of girls to all students on the play is 5 : 8.
Hence, Number of girls = 5x
And, Number of students = 8x
Here, Number of all students = 32
So, We get;
⇒ 8x = 32
⇒ x = 4
Thus, Number of girls = 5x
= 5 × 4
= 20
Hence, Number of girls = 20

For the Christmas dance, they will need 51 songs.
A number that is calculated by adding quantities together and then dividing the total by the number of quantities.
Given that, For the Christmas dance, the dance committee needs three hours of music. Each song is an average of 3.5 minutes.
Converting 3 hours into minutes,
1 hour = 60 minutes
3 hours = 60x3 = 180 minutes
Since, on song is of 3.5 minutes,
So, number of songs that will be played in 3 hours,
= 180/3.5
= 51.42
≈ 51
Hence, the party will have to play 51 songs.
