Step-by-step explanation:

The question is incomplete as we are not told what we are to determine. Consider the following question

Question:

Tomas has two boxes to be shipped. One box weighs 3 kilograms. The other box weighs 720 grams.

a) What is the total weight of the boxes in kilogram?

b) If the shipping cost $8 per kilogram, what is the total cost of shipping.

Solution:

This is a question on measuring mass.

a) Total weight of the two boxes = weight of 1st box + weight of 2nd box

1st box = 3kg

2nd box = 720g

1000 g is equal to 1 kg

720g = (720/1000)kg = 0.72 kg

2nd box = 0.72 kg

Total weight of the two boxes = 3kg + 0.72kg

Total weight of the two boxes = 3.72kg

b) cost of shipping per kg = $8

cost of shipping for 3.72 kg = 8 × 3.72

Total cost of shipping for both boxes = $29.76

from my calculations its 3.72

which is also 3720 grams

i really dont know

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
