The answer is letter c. If we talked about arithmetic sequence it has the explicit formula: A(n)= a+(n-1)d. So it showed in the choices that letter c has the correct formula for arithmetic sequence. It is the only formula if you are going to find nth term of an arithmetic sequence.
Step-by-step explanation:
x = 180-106 = 74°
y = x/2 = 74/2 = 37°
4z+6 =106
4z = 100
z = 25°
Answer:
Total children = 52
Step-by-step explanation:
The question says that "The ratio of boys to girls in the school play is 5 to 8. There are 32 girls participating in the play. How many children participate in the school play?
"
Let there are 5x boys and 8x girls in a school play.
Total no of girls participating in the play = 32
ATQ,
8x = 32
x = 4
Boys = 5x
= 5(4)
= 20
Total children = boys + girls
= 20 + 32
= 52
Hence, there are 52 children participating in the school play.
