We are given
Ronaldo delivers the papers at the rate of 6 papers in 24 minutes
so, number of papers =6 in time =24 minutes
so, firstly we can find rate
rate = ( number of papers)/( time taken)
now, we can find times
Time for 56 papers:
we are given
number of papers =56
rate is
now, we can find time
Time for 41 papers:
we are given
number of papers =41
rate is
now, we can find time
now, we can find time difference
so, we can plug values

Answer:
x intercept is (3.75, 0) and y intercept is (0, 2.5)
Step-by-step explanation:
4x + 6y - 15 = 0
x int = (3.75, 0)
0*6 = 0
4x - 15 = 0
0 + 15 = 4x = 15
15/4 = 4x
x = 3 3/4 or 3.75
y int = (0, 2.5)
0*4 = 0
6y - 15 = 0
15 = 6y
15/6 = y
y = 2.5
Answer:
y = 1/4x+1
Step-by-step explanation:
We have 2 points so we can find the slope
m = (y2-y1)/ (x2-x1)
= (1-2)/(0-4)
= -1/-4
= 1/4
The point (0,1) is the y intercept
We find the y intercept when x=0
We want to find the equation in slope intercept form
y= mx+b where m is the slope and b is the y intercept
y = 1/4x+1
The area of a full circle would be Area = PI x r^2
The diameter would be the width of the dorr, so the radius would be half that. 34/2 = 17 inches.
Area for a full circle would be 3.14 x 17^2 = 907.46 square inches.
A semi circle is a half circle.
The area would be 907.46 / 2 = 453.73 square inches.
Multiply the area by the cost:
453.73 x 0.95 = 431.04
The answer is C.
