If we rotate the 3-D figure around y-axis we'll obtain a cone with a radius of 3 units
There is a 0% chance of selecting either of those letters as they do not appear in the work BULLDOG.
Answer:
x=−3 and y=7
Step-by-step explanation Solve: 7x+2y=−7for x:
7x+2y=−7
7x+2y+−2y=−7+−2y(Add -2y to both sides)
7x=−2y−7

=
−2y−7

Answer:
40.5
Step-by-step explanation:
diameter^2 = (3 +6)^2 + (5+4)^2
or, d^2 = 9^2 + 9^2
or, d^2 = 81 +81
or,d^2 =162
or d=√ 162
• d= 81
then radius = d/2
r = 81/2
•r= 40.5 ans
5 1/3+1 1/3
= 15/3+1/3 3/3+1/3
=20/3
= 18/3+2/3
=6 2/3
OR
when both fractions are the same, you can just add them this way:
5 1/3 + 1/3
= 5+1 + 1/3+1/3
=6+2/3
= 6 2/3
