Answer:
1.45
Step-by-step explanation:
weight of all books= 14×1.1= 15.4
weight of all duster=7×0.2= 1.4
weight of books and duster= 15.4+1.4=16.8
weight of the empty box = 18.25-16.8=1.45
we are given to simplify

Open the bracket and write the like terms together

when the bases are same then the exponents gets added

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
1: 200-75= r
2: 73-29= v
73-29=44
v=44
Okay what’s the rest of the question ?
