Apot of water is being heated up the temperature of the water can be modeled by this equation with y representing the temperature in degrees fahrenheit and d representing the time in minutes that the water has be on the stove
y = 9.5x + 62.1
after how many minutes will the temperature of the water be 138.1 fahrenheit?
|? | minutes

8 minutes

Step-by-step explanation:

To answer this, set the function y = 9.5x + 62.1 = to 138.1 and solve the resulting equation for x:

9.5x + 62.1 = 138.1

We must isolate x.  Start this process by subtracting 62.1 from both sides of this equation, obtaining:

9.5x = 76

Now divide both sides of this equation by 9.5:

x = 76/9.5 = 8

The water  reaches 138.1 degrees F after 8 minutes.

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
