Answer:
or 
Step-by-step explanation:
we know that
the formula to calculate the distance between two points in three dimensions is equal to
Let
-----> coordinates of the barrel of her gun
-----> coordinates of the target
substitute the values
1. 100 minus 5 times a number
2.0.25 multiplied by a number plus 0.6 multiplied by a number
3. 3 times m minus 8 times n divided by 13
Answer:
$14.42
Step-by-step explanation:
Price of Album - $17.00 * .20 = 3.4 (this is the discount)
Then subtract 3.40 from 17.00 to get 13.60
Add the sales tax in by doing $13.60 * 0.06 = $0.82
Add that to the 13.60 to get $14.42 for the total after discount and after tax.
We need to work out first the scale factor of the side length
Side MN correspond to the side JK
Side MN = 3.5 cm
Side JK = 14 cm
Scale factor = 14/3.5 = 4
Side OM correspond to side LJ
Side OM = 12 cm
Side LJ = 12 × 4 = 48 cm
Answer:
115 mi
Step-by-step explanation:
speed = distance/time
distance = speed * time
0.5 hours at 50 mph
distance = 50 mph * 0.5 h = 25 mi
1.5 hours at 60 mph
distance = 60 mph * 1.5 h = 90 mi
total distance = 25 mi + 90 mi = 115 mi
