If we are talking about degrees they should equal 180
Perimeter of the triangle, a+b+c
In this case, a=b=c=28
So, perimeter would be 28*3 = 84 cm
R=fixed rate
m=rate of miles
n= miless
T(n)=total amount per miles(n)
T (n) =mn+r
Answer:
10.375
Step-by-step explanation:
To find the mean, you need to add up all of the numbers and then divide by the amount of numbers.
4 + 5 + 8 + 12 + 12 + 13 + 14 + 15 = 83
83 ÷ 8 = 10.375
So we know that:
City A is -96ft in elevation
City C is -24ft in elevation
City D is (1/4C)ft in elevation.
So, knowing this we can make an equation: 1/4•-24/1=-24/4=-6
So from that, we get the result of City D being -6ft in elevation, or 6ft below sea level.
