Answer:
30% members have voted.
Step-by-step explanation:
Given:
Number of members voted = 3
Number of members didn't vote = 7
We need to find what percentage of people voted.
Solution:
First we will find the total number of members in the election.
Now we can say that;
The total number of members in the election is equal to sum of Number of members voted and Number of members didn't vote.
framing in equation form we get;
The total number of members in the election = 
Now we will find the percentage of people voted.
So we can say that;
Percentage of members voted can be calculated by dividing Number of members voted from The total number of members in the election and then multiplying by 100 we get;
Percentage of members voted = 
Hence 30% members have voted.
Answer:
5 cm
Step-by-step explanation:
We khow that the altitude of this triangle is 1cm shorter than the base
- Let H be our altitude and B our base and A the area of the triangle
- A= (B*H)/2 ⇒ 15=(B*H)/2
- H is 1cm shorter than B ⇒ B=H+1
- H*(H+1)/2=15 ⇒ H*(H+1)=30⇒ H²+H=30⇒H²+H-30+0
that's a quadratic equation . Let's calculate the dicriminant .
Let Δ be the dicriminant
- a=1
- b=1
- c= -30
- Δ=b²-4*a*c = 1²-4*1*(-30)=1+4*30=121≥0
- Δ≥0⇔ that we have two solutions x and y
- x= (-1-
)/2= (-1-11)/2= -6 - y= (-1+
)/2= 10/2 = 5
We have a negative value and a positive one
The altitude is a distance so it can't be negative
H= 5cm
