Answer:
1:3
Step-by-step explanation:
First, you need to make a system of equations for the situation.
Let G represent the number of girls and B represent the number of boys.
Since there are twice as many girls as boys,
G = 2B
There are a total of 30 students in class so,
G + B = 30
or
G + B = TOTAL
In order to find the ratio of BOYS to the TOTAL STUDENTS,
you plug in B values that make up G.
(2B ) + B = TOTAL
3B = TOTAL
B = TOTAL / 3 or (1/3) TOTAL
Since B is one third of the total number of students, the ratio is 1:3.
This question requires you to solve,
(y²)⁵×y⁸ =y⁽²ˣ⁵⁾ × y⁸
= y¹⁰ × y⁸
= y⁽¹⁰⁺⁸⁾
= y¹⁸
The correct answer is y¹⁸
