Answer:
C) a = 10√3, b = 5√3, c = 15 , d = 5
Step-by-step explanation:
Here we use the ratio of 30, 60, 90 degree triangle.
The ratio of sides, 1:√3:2
2x = 10
x = 5
d = 5
b = 5√3
c = 5√3√3
c = 5*3 = 15
c = 15
a = 2(5√3)
a = 10√3
Therefore, a = 10√3, b = 5√3, c = 15 and d = 5
Thank you.
Answer:
B because when you multiply the first number by twelve the first two are correct but the second ones are not
Step-by-step explanation:
Let 
be the smaller integer. The larger integer is then 
, and we have
We omit 
, since 
is negative.
Then for 
we find 
, but this is not odd.
There are no consecutive odd integers that satisfy the given condition!
The correct answer is :85
You can find this out because you would count by fives so : 5, 10, 15, 20, 25 so there are 25 volunteers in the 11-15 hours worked so you would add that to the 21-25 also known as 10 hours worked you also have to add 16-20 also known as 50 so add all that and you get 50 + 25 + 10 = 85
So it's 85
I hope this helped! =)
