Answer:
see below
Step-by-step explanation:
The intersection of A and B is the list of elements that show up in both sets. Then the remaining elements of A and of B are those elements of the respective set that are not in the intersection.
The elements that are not in either A or B are listed at the lower left of the diagram (outside the circles).
There are 2 members of the 9-member set that are in the intersection of A and B. If some set member is chosen at random, the probability it is one of those is 2/9.

Step-by-step explanation:
We graph equations by drawing a number line and placing an open circle on the two values. We fill in the circles if we have . Since we don't, we leave it open. We then shade between the two.
Answer:
The value of the car will be x - (0.15)x after a year.
Step-by-step explanation:
The car was 15% more when it first came out, and the price went down by 15% after a year.
Therefore, to solve this problem, we need to multiply 0.15 by the initial cost, which will tell you how much the car price decreased.
Then, we need to subtract this amount from x, or the initial cost, in order to find how much the car will be worth after a year.
Therefore, the value of the car will be x - (0.15)x after a year.
Hope this helps! :D
Answer – 7 years old
SOLVINGS
Let Kevin’s present age be ‘x’
In 56 years, Kevin’s age will be x + 56
In 56 years, Kevin’s age will be 9x
Therefore, x + 56 = 9x
Solving for x
x + 56 = 9x
9x – x = 56
8x = 56
x = 56/8
x = 7
Kevin is 7 years old right now.
Nope
Step-by-step explanation:
Volume of rectangular prism :
= Base Area × h = l × w × h
Volume of triangular prism :
= Base Area × h
Cuz the base area of triangular prism, the volume is :
(½ × l × w) × h
= ½ lwh
So, the volume of a triangular prism is half of a rectangular prism
