Theres a diagram of a tap fully on and off 180 degrees is fully on, when fully on the tap flows at 18 litres a minute
the rate at which water flows out is in direct proportion to the angle of turn
the tap is turned to 126 degrees, the water flows into a tank with a capacity of 115.92 litres
how long in minutes will it take to fill the tank

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
