Answer:
1 / 1296
Step-by-step explanation:
Rolling a 1 for one of the cubes is 1 / 6
1 / 6 * 1 / 6 * 1 / 6 * 1 / 6 = 1 / 1296
The equation of the line joining the points (4, 9) and (-1, 0) is y = 9/5 x + 9/5
<h3>How to find the equation of a line?</h3>
The formula for calculating the equation of a line is expressed as:
y = mx + b
m is the slope
b is the intercept
Determine the slope:
Slope = 0-9/-1-4
Slope = -9/-5
Slope = 9/5
Determine the y-intecept
0 = 9/5(-1) + b
b = 9/5
Hence the equation of the line is y = 9/5 x + 9/5

Answer:

Step-by-step explanation:
We are given that
Length of roll of sod, l=3 feet
Width of roll of sod, b=1 feet
Length of courtyard, L=60 feet
Breadth of courtyard, B=50 feet
Area of rectangle=
Using the formula
Area of roll of sod=
Area of roll of sod=3 square feet
Area of courtyard=
square feet
Number of rolls of sod needed=
Using the formula
Number of rolls of sod needed=
Number of rolls of sod needed=
This is required expression which represents the number of rolls of sod needed.
