Solution:
we are given that
In a certain grocery store, strawberries cost $6.40 per pound ( 6.40 dollars/lb ).
we have been asked to find the cost per ounce?
As we know that
16 oz=1 lb
so we will divide by 16 to get the cost per ounce.
strawberries cost $6.40 per pound so for 1 oz it will cost 
$
Hence cost per ounce is 0.40 $
Beats me man not enough information
These involve the rules for the power of a point. For questions 6-8, we use the theorem that the square of the length of the tangent is equal to the length of the secant multiplied by the length of its external segment.
6. 6^2 = (3)(x + 3)12 = x + 3x = 9 units
7. 4^2 = (2)(x + 2)8 = x + 2x = 6 units
8. 24^2 = (12)(x + 12)48 = x + 12x = 36 units
9. The included angle is half the difference of the larger and smaller arcs. Since the larger arc is 85 degrees, the smaller is 25 degrees, and the difference is 60. Half this difference is x = 30 degrees.
10. The angles at the intersection are vertical angles, so both equal to 65 degrees. Then the sum of the intercepted arcs must be equal to double of the vertical angle: 2 x 65 = 130 degrees. Since one is 95 degrees, the other is x = 130 - 95 = 35 degrees.
In the given figure three angles are marked x°, 56° and 146 °
When two lines intersect they form two pairs of opposite angles. Vertical angles are always congruent, which means that they are equal.
In the figure angles x ,56 and 146 are formed on two opposite sides of the straight lines are so are vertically opposite angles and hence they are equal.
We can write this as x+56=146.
The first option is the right answer.
