I'm not too sure but i think:
A
_ r = x
Y
Answer:
7/4
Step-by-step explanation:
The measurement of angle b is 128°
There are 12 inches in 1 foot.
Divide 46 inches by 12 inches to get how many feet there are.
46/12 = 3.83
46 inches is about 3.83 feet.
Answer:
luxury=15
sports cars 25
Step-by-step explanation:
Step one:
let the luxury cars be x
and the sports cars be y
the objective function is
maximize
15000x+16000y=625000------1
the constraints are
1. Man-hours
1600x+1500y=61500-----------2
Step two:
the system of equation for the situation is
15000x+16000y=625000------1
1600x+1500y=61500-----------2
let us reduce both equation
divide equation 1 be 1000
and equation 2 by 100 we have
15x+16y=625--------1 x15
16x+15y=615--------2 x16
225x+240y=9375
-256x+240y=9840
=-31x+0=-465
31x=465
x=465/31
x=15
put x=15 in 15x+16y=625 we have
15(15)+16y=625
225+16y=625
16y=625-225
16y=400
y=400/16
y=25
