C is the y intercept of the line
Answer:
a. $629.10
b. $635.80
c. $6.70
Step-by-step explanation:
The first thing we need to do is turn these percentages into decimal values by dividing them by 100, this would make 10% into 0.10 and 15% into 0.15. Now we can make the following equations to calculate the total by multiplying the 100 pens by the individual pricer per pen, and then multiplying that product by the 1 minus the discount percentage.
A) (100 * 6.99) * (1 - 0.10) = x
699 * 0.90 = x
$629.10 = x
B) (100 * 7.48) * (1 - 0.15) = x
748 * 0.85 = x
$635.80 = x
C) 635.80 - 629.10 = $6.70
The difference is $6.70 more for the 100 pens in the second store.
Answer:
60
Step-by-step explanation:
m∠1=(55+65)/2=60
See diagram
so we got a right triangle
so for a right triangle, when we've got legs a and b and hytponuse c then
a²+b²=c²
so the legs are 90 and 90
hytponuse is distance from home to 2nd
so
90²+90²=c²
8100+8100²=c²
16200=c²
sqrt both sides
90√2=c
