Answer:
658 + 342 = 1000.
Step-by-step explanation:
Let x be the multiple of 47 and y be the multiple of 19 which gives 1000 while adding.Hence 47x + 19y = 1000On multiplying, find x and yX=14 and y=18So, 47*14= 658 and 19*18= 342 On adding, 658+342=1000Therefore, 658 and 342 are the two parts of 1000.
in simple way
47a + 19b = 1000
a = 14, b = 18
check: 14 x 47 = 658, 18 x 19 = 342, 658 + 342 = 1000.
Answer:
Step-by-step explanation:
The given function is
We need to find first partial derivatives of the function.
Differentiate partially w.r.t. x and y, z are constants.
Differentiate partially w.r.t. y and x, z are constants.
Differentiate partially w.r.t. z and x, y are constants.
Therefore, the first partial derivatives of the function are 
.
Answer:
210 dollars in 18 hours
Step-by-step explanation:
175 / 15 = 11.6666666667
11.6666666667 times 18 equals 210 dollars
Answer: 4,000 cubic feet
Step-by-step explanation:
Volume=LWH (Length times width times height, nay base times height)
V=40*20*5
V=40*20*5= 4000
Answer: 4,000 cubic ft.
Answer:11.5
Step-by-step explanation:
distance=6 2/5 + 2 3/4 + 2 1/3
d=(5x6+2)/5 + (4x2+3)/4 + (3x2+1)/3
d=32/5 + 11/4 + 7/3
d=(12x32+15x11+20x7) ➗ 60
d=(384+165+140) ➗ 60
d=689 ➗ 60
d=11.5
