To factore 5b - 15 c you have to find a least common multiple which happens to b 5
Divide all factors by 5
answer : b - 3c
Answer:
You must produce 12 units
Step-by-step explanation:
19.35 - 9.75=9.60
9.6/0.8=12
Solve for x by simplifying both sides of the equation, then isolating the variable.
X= 11,3
For Independent Events, P(A) × P(B) = P(A∩B)
so we have, P(A∩B) = 0.4×0.1 = 0.04
P(A') = 1 - 0.4 = 0.6
This information can be represented on a Venn diagram as shown below
P(A'∪B) means the union of everything that is not A with everything that is B
P(A'∪B) = 0.06 + 0.54 + 0.04 = 0.64
First I'd suggest plotting the points on a graph so that you can visualize the problem. What you're trying to find is the area of the triangle that the three points given will form. The area of a triangle is
where b is the size of the base of the triangle and h is the height of the triangle. From graphing the three points and connecting them, you can see that the base of the right triangle formed is 4 units/gridlines and the height of the right triangle is 7 units/gridlines. SInce the problem specifies that each gridline is 2 feet, that means that the base 4 x 2 = 8 feet, and the height is 7 x 2 = 14 feet. Now you just plug these values into the equation for the area of a triangle to get
feet squared as the area that will be covered in gravel.
