Answer:
20 girls
Step-by-step explanation:
if there are 10 girls to 2 boys when you doble it you get 20 girls to 4 boys but when you add 20 and 4 together you get 24 students
20 girls.
The girl to boy ratio is 10 to 2.
Insert the multiplier m and write an equation for the total number of students:
10 m + 2 m = 24, or
12 m = 24. Then m = 2.
The number of girls is 10(m) = 10 m = 10(2) = 20.
The number of boys is 2(m) = 4
Note that 20 (girls) + 4 (boys) = 24 (students), as specified.
Note that 20/4 = 10/2, which is the given ratio.
Answer: right triangle is a triangle with one angle equal 90. That being said, the total of all angles = 180. 1 of them is 90 which makes the sum of the 2 acute angles = 90. One acute angle = 30 => the second one = 90 - 30 = 60 degree
they are perpendicular
because the slope are opposite which means the lines intersect.
