Answer:
5/7
Step-by-step explanation:
First calculate the total number of students:
Girls + boys
= 46 + 115
= 161
Then divide the number of boys over all students
= 115/161
= 5/7
Answer:
Ratio of area of triangles MNP and ABC is 1.05
Step-by-step explanation:
There are 2 triangles ABC and MNP.
We are given that ,m∠A = m∠M.
AB = 16 and AC = 10.
MN = 7 and MP = 24.
Area of a triangle ∝ Product of any two sides.
So area of triangle ABC ∝ 16
Area of triangle ABC = 160
,
where k is a constant.
So area of triangle MNP ∝ 7 
Area of triangle MNP = 168
So ratio of area of triangles = 
= 
= 1.05
96(over)100 in a fraction form
The number between -1 and 10 means start counting from 0 and stop just before 10. Which is 9. And only include the odd integers.
So, the set will be {1, 3, 5, 7, 9}.
EDIT:
I want to give a thank you to Helpwithschool for finding a mistake in my answer!
You would earn $34 in total because 3x3 equals 9. And 12+5+7=24. 9+24÷35
