Answer:

Step-by-step explanation:
combine by putting together
Given:
In a number, adding
, then multiplying the result by
we get 8.
To find:
The unknown number.
Solution:
Let the unknown number be x.
According to the question,




Multiply both sides by
.


Subtract
from both sides.




Therefore, the required number is
.
Answer:
x^2+(y-1)^2=25
Step-by-step explanation:
eqn of circle : (x-h)^2+(y-k)^2=r^2
center of circle = (h,k)
hence, the center of the current circle is (2,3)
moving 2 units to the left would make the center (0,1)
the radius would remain the same (5) , hence the new eqn would be
(x-0)^2+(y-1)^2=25
x^2+(y-1)^2=25
Answer: 80 cubic centimeters
Step-by-step explanation:
Use the formula: V=
Bh
(B is the area of the pyramid's base)
V=
(16)(15)
Multiply: 16 x 15 =240
x 240 = 80
V= 80cubic centimeters
