1. The ratio of boys to girls is 4/5. If there
are 24 boys, how many girls are there?
Answers
Given:
The ratio of boys to girls is [tex]\dfrac{4}{5}[/tex].
Number of boys = 24
To find:
The number of girls.
Solution:
We have,
Boys: Girls = 4:5
Let the number of boys be 4x and number of girls be 5x.
[tex]4x=24[/tex]
[tex]x=\dfrac{24}{4}[/tex]
[tex]x=6[/tex]
Now,
Number of girls = [tex]5x[/tex]
= [tex]5(6)[/tex]
= [tex]30[/tex]
Therefore, the number of girls is 30.

Write down in terms of n an expression of the nth terms?
Answers
Answer:
A. nth term = 4 + (n - 1) -3
B. nth term = -7 + (n - 1) -5
Step-by-step explanation:
A. 4, 1, -2, -5, -8
First term, a = 4
Common difference, d = 1 - 4 = -3
nth term = a + (n-1)d
nth term = 4 + (n - 1) -3
B. -7, -12, -17, -22, - 27
First term, a = -7
Common difference, d = -12 - (-7)
= -12 + 7
= -5
nth terms = a + (n - 1)d
nth term = -7 + (n - 1) -5

A. For each input value, x, there is exactly one output value, y.
Step-by-step explanation:
A function always have exactly one output value (y-value) that is related or assigned to each input value (x-value), however, two different x-values can have the same y-value.
In the graph given, although two different values have the same y-value, every x-value has exactly one y-value corresponding to it. No x-value has two different y-values.
Therefore, the graph represents a function.
