Explanation:
The sales tax rate is usually a percentage (assumed here).
6.5
percent equals
0.065
(percent means "per 100" so is divided by
100
).
Step-by-step explanation:
<span>L = 2W + 5
A = LW = 63
L = 63/W
W=63/L
L = 2W + 5
63/W = 2W + 5
63 = 2WW + 5W
2WW + 5W - 63 = 0
2WW + 5W - 63 = 0
is already in quadratic equation form: ax^2 + bx + c = 0
use the quadratic formula to solve for two solutions:
x = ( -b +- sqrt( bb - 4ac ) ) / 2a
the two solutions are:
x = 9/2
x = -7
you cant have a negative solution for length so use the positive one
solve for length:
L=5+2(9/2)
L=5+18/2
L=5+9
L=14
W = 9/2
L = 14</span>
Answer:
1295$
Step-by-step explanation:
Let's denote the monthly salary of Barry A.
Then we have:
A - (1/5)A - (1/7)A = 851
or
(35A - 7A - 5A)/35 = 851
or
23A = 851 x 35
or
23A = 19785
or
A = 1295$
Answer:
96 minutes.
Step-by-step explanation:
17 miles = 204 minutes
1 mile = ?
204/17 = 12 minutes
1 mile = 12 minutes
8 miles = ?
8 × 12 = 96 minutes
It would take Liset 96 minutes to run 8 miles.
