In the construction world, most materials are measured in cubic yards. Multiply the length (L), in feet, by the width (W), in feet, by the height (H), in feet, and divide by 27. This number is how many cubic yards of crushed stone you need.
Multiply the first equation by 2 or divide the second one my 2, to get the #X opposites, to cancel each other out
-4x+6y=12
4x-6y=-6
Or
-2x+3y=6
2x-3y=-3
there’s no solution either way
Answer:
I belive it is 'A' 9
Step-by-step explanation:
because the square root is 8.66025404 so that rounded to the nearest integer would be 9
Answer:
Length of the minor arc AB = 5.27777777778 cm
Step-by-step explanation:
Here you would require a simple proportionality.
The ratio of the degree of the minor arc (95 degrees) over the total, 360 degrees of every circle, comparative to the length of the minor over the circumference (20 cm).
Here we can propose that the length of the minor can be equal to x.
Now let's substitute the known values:
95 / 360 = x / 20
Now cross multiply:
360 * x = 95 * 20 ⇒
360x = 1900 ⇒
x = 5.27777777778 ⇒
length of the minor arc AB = 5.27777777778 cm
