The asnwer is 28. Since 7 is one of the factors,and 7+x=11,you would do 11-7 to find x. After doing 11-7 to find x (4),then you multiply 7 and 4 since they are the factors of the missing number. 7×4 is 28,therefore,you are the number 28.
Answer:
x^2 + y^2 -2x -8y -47 =0
Step-by-step explanation:
The center is at (1,4) and the radius is 8 units
We can write the equation as
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x-1)^2 + (y-4)^2 = 8^2
Foil
x^2 -2x+1 + y^2 -8y +16 = 64
x^2 + y^2 -2x -8y +17 =64
Subtract 64 from each side
x^2 + y^2 -2x -8y +17-64 =64-64
x^2 + y^2 -2x -8y -47 =0
Answer:
the answer is 5 hours or less which is 5 and the < sign with line under which means they have equal to and less than that so the most hours they can do is 5
Step-by-step explanation:
you have 275
you subtract 50 from 275
275-50=225
divide 225 by 45
225/45=5
ANSWER
66 cubic units
EXPLANATION
The volume of a triangular prism is the area of the triangular base times the height of the prism.
We calculate the volume using the formula:
where b=4 is the base of the triangle and h=3 is the height of the triangle.
H=11 is the height of the prism.
We substitute these values to get;
