9514 1404 393

Answer:

  (n, d) = (56, 68)

  Hunter has 56 nickels and 68 dimes.

Step-by-step explanation:

The equations can be solved by using the second equation to substitute for d in the first equation.

  10(n +12) +5n = 960

  120 +15n = 960 . . . . . . . eliminate parentheses

  15n = 840 . . . . . . . . . . . . subtract 120

  n = 56 . . . . . . . . . . . . . . . divide by 15

  d = 56 +12 = 68 . . . . . . . find d

The solution is n = 56, d = 68. This means Hunter has 56 nickels and 68 dimes.

_____

The meaning of the solution comes from the definitions of the variables.

The prime cost of an article was four times the value of material used. The cost of raw materials was increased in the ratio 3 :
jenyasd209 [6]

Answer:

Step-by-step explanation:

The prime cost = 4 times the value of material used

Former Prime cost = 540

Value of material = 540 / 4 = Rs. 135

Since ;

Prime cost = raw material + wages

540 = 135 + wages

Wages = 540 - 135

Wages = 405

Increase in raw material ; 3 : 4

New cost of raw materials = (4/3) * 135 = 180

Decrease in wage ; 4 : 5

New wage = 4/5 * 405 = 324

New prime cost :

180 + 324

= 504

How do I solve for tan(p)
a_sh-v [17]
The tan function goes by the syntax (setup) of tan(O/A) where O is the side opposite of the chosen angle, and A is the adjacent (next to) side from the angle. 
To find an angle, you would use tan^-1(O/A);. This is called the tangent inverse.
This gives you tan^-1(12/16) which is 36.87 (if you need to find an angle.
If you just want to find tan(p) you would do tan(12/16) which is 0.01

A construction company charges $15 per hour for demolition Plus a one time $50 fee for the use of trash dumpsters how much would
iogann1982 [59]

Answer:

<em>$170</em>

<em></em>

Step-by-step explanation:

Given that:

One time fee for the use of trash dumpsters = $50

Charges for demolition per hour = $15

Time period for which trash dumpsters are used per day = 8 hours

To find:

The cost of 8 hours of operation = ?

Solution:

Here, to find the required cost, we need to first multiply the number of hours with the per hour cost of using the trash dumpsters.

And then we need to add the fixed / one time cost of the trash dumpsters to find the required cost.

Cost for using it for 8 hours = 8 \times 15 = \$120

Total cost for using it for full 8 hours = Cost for using it for 8 hours + One time cost = $120 + $50 = <em>$170</em>

<em></em>

Therefore, the answer is: <em>$170</em>
