An angle measuring (525n)° is in standard position. For which value of n will the terminal side fall along the negative portion
Mazyrski [523]

For n=2,

put the value 2 in the above equation we get 525*2=1050°.

1050° angle takes 2 complete revolution and then makes an angle of 330° which will fall in the negative portion of y-axis.


For n=6,

put the value 6 in the above equation we get 525*6=3150°.

3150° angle takes 8 complete revolution and then makes an angle of 270° which will fall along negative y-axis.

A candy manufacturer makes two types of special candy, say A and B. Candy A consists of equal parts of dark chocolate and carame
Sphinxa [80]
If we let x as candy A
y as candy B
a as dark chocolate in candy a
b as dark chocolate in candy b
c as caramel
d as walnut
P as profit
we have the equations:
a + c = x
2b + d = y
a + 2b ≤ 360
c ≤ 430
d ≤ 210
P = 285x + 260y

This is an optimization problem which involves linear programming. It can be solved by graphical method or by algebraic solution.
P = 285(a + c) + 260(2b +d)
If we assume a = b
Then a = 120, 2b = 240
P = 285(120 + 120) + 260(240 + 120)
P = 162000
candy A should be = 240
candy B should be = 360

For what value of the variable will<br> b<br> the value of 3−5c be 1 less than the value of 1−c?
Crank

Answer:

c = 3/4

Step-by-step explanation:

Lets set up an equation.

You can get

3-5c + 1 = 1-c to show that it is one less.

now we can solve it.

So by combining like terms, we get:

4-5c = 1-c

that then becomes:

3-5c = -c

--> 3 = 4c

--> c = 3/4

A playground measures 300 m × 170 m.Find the cost of planting grass on this at the rate of Rs 80 per hectare.​
Ierofanga [76]
<h2><u>Answer</u> :-</h2>

To find the cost of planting grass , we have to find area of the field.

Area of field = Length × Breadth

{= 300×170}

{=51000 sq. m}

Now convert into hectare.

1 hectare = 10000m sq.

51000 / 10000

So area field = 5.1 hectare sq.

Now cost = 5.1 x 0.80 p

{= 0.408 p}
