Cos x = sin (90 - x)
cos 63 = sin (90 - 63)
cos 63 = sin 27
x = 27
Answer:
No.
Step-by-step explanation:
The equipment wll save $35,000 per over for 10 years, which totals to $350,000.
If the equipment is bought on a simple interest rate of 12% annually for ten years, it will cost:
We will need to pay $440,000 in total for the machine in over ten years.
If we compare both values, it can be deduced that industrial equipment is more expensive than labor cost.
$105.65/5 shirts = $21.13/shirt
Answer:
Let x be the number of regular health bars you buy and y the number of strawberry health bars you buy. Then:
0.75x+1.25y=3.75
x+y>=3
Step-by-step explanation:
For the first equation, we have to assume that you will spend all of your money, otherwise it becomes an inequation. The money you spend on regular bars is 0.75x dollars and the money you spend on strawberry bars is 1.25y, so if you spend your 3.75 dollars on the bars, then 0.75x+1.25y=3.75.
For the second, you will always buy x+y health bars, regular and strawberry. There isn't enough information to make this into a equation, the only thing we can deduce is the inequation x+y>=3.
If we also assume that x and y are integers (we can't buy half-bars or one-fourth of a bar) then the minimum number of bars we can buy is 3 (3 strawberry bars) and the maximum is 5 bars (5 regular bars). x+y must be an integer too, so the possibilities for the second equation are x+y=3, x+y=4 and x+y=5. There is a finite number of solutions in any case.
The answer to (-7)+1+4= -2
