A machine makes 150 boxes in 15 minutes what is the rate

The rate of the machine is 10 boxes per min.

Step-by-step explanation:

Given,

A machine can make 150 boxes in 15 min

To find the rate of the machine

Meaning to find the number of boxes machine it can make in 1 min

We will apply unitary method.

In 15 min it makes 150 boxes

In 1 min it makes (150÷15) boxes = 10 boxes

Hence the rate is 10 boxes per min.

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
