Answer:
8 ounces
Step-by-step explanation:
To solve the exercise the first thing is to find the equivalence between pound and ounce.
We know that 1 pound equals 16 ounces. In this exercise we have 1/2 pounds, that is, half a pound or 0.5 pounds, therefore:
1/2 pound * 16 ounces / 1 pound = 8 ounces
Which means that he bought 8 ounces of grapes and not 5 how he had put it.
The measure of the ∠Q = 41°
By law of cosines:
a law in trigonometry: the square of a side of a plane triangle equals the sum of the squares of the remaining sides minus twice the product of those sides and the cosine of the angle between them.
Which can we stated as:
solving equation using normal algebra:
60cos(Q) = 36 + 25 - 16
60 cos(Q) = 45
cos(Q) = 45/60
cos(Q) = 3/4
Thus, Q = 41°
Hence, the measure of the smallest angle in a triangle whose sides have lengths 4, 5, and 6. ∠Q is 41°.

Using proportions, it is found that Student 2 is correct, as 37.6/0.1 = 376.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
One tenth is worth 0.1. How many tenths are there in 37.6? The division is given as follows:
37.6/0.1 = 376.
Hence student 2 is correct, as there are 376 tenths in 37.6.
