Answer: b) 2y\leq 25x and y\geq 245


Step-by-step explanation:

If y represents students .

"There are at least 245 students enrolled in the school" gives

y\geq 245

Since school rules permit no fewer (atleast) than 2 teachers per 25 students.

Thus the rate of teachers=\frac{x}{y}\geq \frac{2}{25}

\\\Rightarrow25x\geq 2y

Hence, b is the right option.

A circular ice skating rink has a diameter of 65 feet. What is the circumference of the rink, rounded to the nearest tenth.
Nezavi [6.7K]
The meaning of circumference is to find the distance around a circle or in other words the perimeter of the circle. The circumference of a circle can be calculate by using the formula C=2πr or C=πd.

In this exercise is given that a circular ice skating rink has a diameter of 65 feet, and it is asked to find its circumference. In <span>this problem the diameter of the circle is given, so in this case the formula C=</span><span>πd would be used, where d represents the diameter.

C=</span>πd
C=π(65 ft)
C=204.2 feet

The circumference of the circular ice skating rink is 204.2 feet.

1/3y+1/4=5/12<br> Can someone give me easy steps for this
Liula [17]
  1) Set the equation equal to 0.
In order to do that, subtract 5/12 on both sides of the equation. Now you have 1/3y-1/6=0. If you need just an equation, there it is. If you need to go farther to find y, continue to step two.
  2) Now get the variable by itself.
Add 1/6 to both sides. Now you have 1/3y=1/6.
  3) Now divide 1/3y by both sides- but wait- it's a fraction.
So you have to multiply by the reciprocal which means multiply by 3 to both sides in this case.

So y=1/2.
Hope that's right and that it helped!
