Answer:
Step-by-step explanation:
12). By applying Pythagoras theorem in the given right triangle,
Hypotenuse² = (Leg 1)² + (Leg 2)²
x² = 7² + 7²
x² = 2(7)²
x = 
x = 
13). By sine rule,
sin(60)° = 
y = 
y = 18
By cosine rule,
cos(60)° = 
x = 
x = 
14). By applying Pythagoras theorem in the given right triangle,
12² = x² + x²
144 = 2x²
72 = x²
x = √72
x = 6√2
So first we need to get rid of that naughty sales tax so we need to divide 30.45 by 1.05 since 30.45 is 105% of the pre-tax price. We get the answer of 29 and subtract 12 from 29 since the long fleece socks cost 12 bucks and we get 17 dollars. Since there are 2 pairs of regular songs we divide 17 by 2 and get 8.5
So the regular socks cost $8.50
Checking work 8.5*2=17
12+17=29
1.05*29=30.45

"Quantitative" information is information that consists of numbers
and tells you the measure (quantity) of something.
The cost, mileage, and weight of the car are all quantitative items.
The model of the car may have numbers in it, but it doesn't tell
the measure of anything. It isn't quantitative data.
a. "The newer car is more expensive" is false. The leftmost graph is a graph of cost versus time; you can see that as you increase in age, the cost lowers (point B to point A).
b. "The slower car is larger" is true. Middle graph is the relevant one. You can see that as cruising speed increases, the size decreases. Point A is the larger car than point B
c. We have to use multiple graphs. We see that car A is the larger car from the middle graph but car A is older than car B from the left graph. So no, the larger car is newer is false.
d. A is the cheapter car and it carries more capacity. True
