Assume that the cost of the milk is x.
We are given that a sandwich costs 0.75$ more than the cost of milk. This means that:
cost of sandwich = cost of milk + 0.75
cost of sandwich = x + 0.75
Now, the customer bought 4 sandwiches and 4 containers of milk at the cost of 7$.
We will transform this into an equation as follows:
total cost = cost of 4 sandwiches + cost of 4 containers of milk
7 = 4(x+0.75) + 4(x)
Solve the above equation to get x as follows:
7 = 4x + 3 + 4x
7-3 = 8x
8x = 4
x = 0.5
Therefore:
cost of milk = x = $0.5
cost of sandwich = x+0.75 = 0.5+0.75 = $1.25

Answer:
4. b) an angle
5. b) the angles of a triangle
6. b) opposite, hypotenuse and adjacent
Step-by-step explanation:
4. To find sine, cosine, tangent, you use the sin, cos, tan key of the calculator.
If you are given the value of the sin, cos, tan, and you are looking for the angle, then you use the second function of the calculator.
Answer: b) angle
5. angles of a triangle
6. The sides that form the right angle are the legs. In trig, there is an angle of interest, so to distinguish between the legs, one leg is called the adjacent leg, and the other leg is called the opposite leg. The side opposite the right angle is the hypotenuse.
Answer: opposite, hypotenuse and adjacent
