Answer: Measure the angle of each slice of the pie chart and divide by 360 degrees. Now multiply the value by 100.
Step-by-step explanation:
Answer:
4
Step-by-step explanation: If this regarding the splitting of two polynomials put through the pyth theorem.
The general formula for a line is y=mx+c, where m is the gradient (slope) and c is the intercept.
We can extrapolate c from the graph directly - it intercepts the y axis at -1, so c has a value of -1.
The gradient can be calculated by determining what the y value changes by for each value of x. Since this evidently has a fraction gradient, it's easier to take whole numbers.
We can see a triangle with whole numbers - from (-3,0) to (0,-1). The difference in x is +3 and the difference in y is -1. Dividing these gives us -1/3.
Therefore, the gradient of the graph (i.e. m) is
-1/3Putting these together:
To turn 4 5/6 into an improper fraction
you do 6 x 4 + 5 = 29
which makes 29/6
if you don't get it

So you have to calculate the volume
volume=height times area of base
area of base=area of circle=pi r^2
volume=hpir^2
we need radius but we are given diameter
2r=d
r=d/2
d=5
r=5/2=2.5
height=10
pi=3.14 for this question
so
volume=10 times 3.14 times 2.5^2
volume=31.4 times 6.25
volume=196.25
volume of face wash is 196.25
it is half empty
196.25 times 1/2=98.125 cm^3
so
4 cm^3 used every niehgt
so
x=number of nights
4 times x nights=volume of remaining
4x=98.125
divide boht isdes by 4
x=24.53
round to nearest whole number
25
answer is 25 days
