Answer:
Priya's age = 15
Amirah's age = 19
Shirley's age = 13
Step-by-step explanation:
Let x be the age of Priya.
According to the question,
Amirah's age = x + 4
Shirley's age = x - 2
Their sum is 47.
So,
x + 4 + x + x - 2 = 47
3x + 2 = 47
3x = 47 - 2
3x = 45
x = 45/3
x = 15
So,
Priya's age = 15
Amirah's age = 15 + 4 = 19
Shirley's age = 15 - 2 = 13

Answer:
B. Figure B
Step-by-step explanation:
The figure is difficult to read. We assume the height of the pyramid is 9, and the radius of the cylinder is 1.
The pyramid volume is ...
V = 1/3Bh
V = 1/3(4²)(9) = 48 . . . cubic units
__
The cylinder volume is ...
V = πr²h
V = π(1²)(48) = 48π . . . cubic units
The cylinder has π times as much volume as the pyramid. Figure B is larger.
_____
<em>Additional comment</em>
If the diameter (not the radius) of the cylinder is 1 unit, then its volume is 12π cubic units and the pyramid has more volume.
Answer:
Step-by-step explanation: her precent change is 12% because 32 - 20 = 12 and since 12 is a whole number that would make it 12%
Radius of design= 18 in
Area of design= pi*r^2
= 3.14*324
= 1017.36 sq. in
1017.36/144
= 7.065 sq. ft
7.065*35
= 247.275
Therefore, the cost of building the design costs $247.275 to make
im not going to give the answer but i am going to help you
Step-by-step explanation:
look the median is just the middle, if there is 2 medians then you add those 2 and then divide by 2 to get the MEDIAN in absolute.
now to find the mean all you do is simple you first add all of the numbers below then you would divide by how many numbers you have?
I hope this helps if not then have a nice day
