sqrt(2/3) = 0.816496
since it is a decimal with no repeating numbers it would be irrational
Answer:
No
Step-by-step explanation:
as X=-1. and y=5
according to this y<3x+8
which means 5< 3*-1 +8
5<-3+8
5<5
which is not true.. as 5=5
Answer:
income=2*expenses-100
Step-by-step explanation:
income=a*expenses+b
a:slope
a=(income of 1 - income of 0)/(expenses of 1 - expenses of 0)
=(10-0)/(55-50)=10/5=2
income=2*expenses+b
for product 0
income=0
expenses=50
》0=2*(50)+b
b=-100
income=2*expenses-100
D) $20 because if you plug it in to the equation it equals $225
Answer:
Step-by-step explanation:
<u>Given:</u>
- Horizontal leg of the right triangle = 778 ft
- Angle opposite to vertical length = 39°
- Vertical leg = h
<u>Use tangent to solve for h:</u>
- h/778 = tan 39°
- h / 778 = 0.81
- h = 0.81*778
- h = 630.18
Correct choice is B
